Digital Camera
Tips and Tricks
Shoot at the Highest Resolution
Always shoot at the highest resolution your camera offers. For example, the
D-620L from Olympus shoots at two resolutions: 1,280 by 1,024 or 640 by 512 pixels.
You can shoot four times as many of the smaller pictures, but they'll be only
one-fourth as good. This goes even when shooting photos for the Web--a large
original picture provides more flexibility, permitting you to crop, reduce the
image size, or perform a combination of the two. Remember, you can always reduce
the number of pixels in an image, but you can't magically invent more. If you
shell out the bucks for high resolution, and you should, you might as well use
it.
Get in Close
Ever wonder why all the vacation shots of you and your companions taken by other
tourists look terrible? It's because the stand-in photographers step back half a
mile away when they take the shots. With a digital camera, that means you end up
taking about 15 pixels in the center of the image. Pixels are scarce, so you
need to devote as many to the subject of the photograph as possible. When
photographing a person, turn on the LCD and close in until that person fills up
the screen. Don't take the shot until you see the whites of their eyes.
Shoot in Pairs
When shooting important images--staff parties, family functions, vacation
photos--don't settle for a single shot. Like butterflies, digital pictures are
free, so go nuts. The rule of thumb is to take no fewer than two pictures of
virtually everything, four or five if the scene is even moderately interesting.
Think fashion photographer: keep moving that camera and firing off shots. With
lots of variations to choose from, there's a higher probability of getting a
good photograph.
Shoot Big
Pixels don't treat all objects equally. About the worst thing you can photograph
with a digital camera is a tree. If the camera captures about a million pixels,
and the tree contains a few hundred thousand leaves, you end up with three or
four pixels per leaf, so it all smears together in a big, gummy mess. The same
goes for lawns, gardens, distant mountains, hairy surfaces, or anything else
with scads of intricate details. For the best results, photograph clearly
defined subjects with smooth, distinct outlines. People photograph well, as do
cars, buildings, furniture, and most man-made objects. Stick to obvious
foreground subjects that stand out clearly from their backgrounds, and you
should be fine.
Eliminate Red-Eye
If you've ever shot a picture with a flash, you've no doubt encountered red-eye,
in which everyone's pupils turn bright red, giving them a mildly demonic look.
The culprit is dilated pupils. In dim light, the pupils are nice and big,
permitting the flash to bounce off the inside of the retina and reflect back
into the camera lens. One solution is to turn on your camera's red-eye reduction
flash. This provides a preflash, which reduces pupil sizes so that the second
flash is reflected harmlessly off the iris. The problem with a preflash is that
it causes people to blink--and most of us would rather get red-eye than a bunch
of closed eyelids. A better solution is to turn on a few lights or to shoot in a
shaded area outdoors. By shining some light on a situation, you reduce pupil
sizes naturally and limit your risk of red-eye.
Shoot Outside in Indirect Light
Most digital cameras offer built-in flashes, but they're not very good. When
shooting in a dimly lit room or at night, a subject a few feet away will appear
as a luminous ghoul against a pitch-black background. For the best results,
shoot outside or in a naturally lit room during the day. A little cloud cover or
tree shadow helps to soften the harsh color transitions you often get in direct
sunlight. Counterintuitive as it may sound, low contrast is better than high
contrast. There's nothing worse than a large area of white (called a hot spot)
or black in a photo, because there's no way to fix it.
Use the Flash in Backlit Conditions
The best use for a cheesy consumer flash is to fill in shadows in full daylight.
When you photograph a person against a bright sky--a condition called
backlighting--the camera averages the light from the person and the sky and
comes up with an intermediate exposure. But that exposure is too brief for the
person and too long for the sky, so you get a dark silhouette against a
blindingly bright background. The solution is to turn on the flash, a technique
called fill-flashing. This not only lightens up the person, it also reduces the
exposure so that the sky appears less bright.
Avoid Digital Zoom
Many digital cameras offer two kinds of zoom: an optical zoom and a digital
zoom. Of the two, the optical zoom is the only one you should use. An optical
zoom uses a system of lenses to refract light and to magnify an image onto the
CCD. The result is expanded detail and clarity. A digital zoom crops and
enlarges images, inventing pixels through interpolation. The result is a
magnified but fuzzy image. If an optical zoom doesn't enlarge an image
sufficiently, walk closer to your subject, but try to avoid the digital zoom.
Use the LCD for Close-Ups
Very few digital cameras under $1,000 offer single-lens reflex (SLR)
viewfinders, the kind in which you and the camera see through the same lens. Far
more popular is the rangefinder design, in which you see through one lens, the
optical viewfinder, and the camera sees through another, the primary lens
element. Although these lenses are designed to converge at the same point, they
can't help but vary slightly as you zoom in and out. And they may vary
dramatically during close-up shots, a phenomenon known as parallax. Therefore,
most optical viewfinders are highly suspect.
The more accurate framing device is the LCD screen: turn it on and you get a
live video feed directly from the CCD. Consequently, what you see on the LCD
screen is more representative of what you'll get. Be aware, however, that the
LCD requires scads of power and quickly drains the batteries. A standard set of
rechargeable AA cells will last about 50 to 80 shots with the LCD turned on,
compared to four times that many with the LCD off. So limit your use of the LCD
to close-up shots, and keep an extra set of batteries fully charged and close at
hand.
Use Accessory Lenses to Extend Your Range
Most digital camera lenses are 3x optical zooms. While this is a sufficient
range for many photo situations, you might find yourself wanting more range for
wide-angle and telephoto compositions. The good news is that you can achieve
greater focal-length range by adding accessory lenses to your system. There are
many such lenses available today for use with a growing number of cameras. These
lenses can add ultra-wide and extreme-telephoto capabilities to your camera’s
fixed zoom lens.
Accessory lenses attach to the camera’s fixed lens either directly or with an
optional adapter mount. If this is something you’ll want to consider, be sure
your camera can accept such lenses before you buy.
Stick to Optical Zoom
When you choose a digital camera, you’ll notice that there are a couple of zoom
figures listed on the box and other promotional material. One is the optical
zoom and the other is the digital zoom. Typically, optical zoom is about 3x or
4x, while digital zoom can be closer to 10x and higher. The difference between
the two is that optical zoom is achieved through use of the lens elements while
digital zoom is achieved by cropping in on the image sensor, then interpolating
the resultant image file to higher resolution. I recommend that for maximum
image quality you stick to using only the optical zoom. The newest digital
cameras on the market have vastly improved digital zoom algorithms than were
available just a few years ago. These improvements make the digital zoom much
more useful, but it’s still a compromise.
Take Advantage of Scene Modes
Many digital cameras offer pre-programmed “scene” modes that make getting the
perfect exposure easier. Landscape, portrait and night shot are a few of the
most common modes, although some cameras offer many more. Set your camera
to the appropriate mode for the circumstances and it will automatically select
the aperture, shutter speed, flash and other exposure choices for the best
results possible. These modes are a terrific tool when you want to make the most
of a scene without being bogged down with manual settings.
Battery Power
Batteries are a key issue for digital cameras. One of the worst experiences for
a photographer is to be photographing and have the camera die with no chance of
recovery. A good policy is to own three batteries (or sets) for your camera and
a charger separate from your camera. This way, you can have a fully charged
battery in your camera, a fully charged battery in your bag and the third
battery on your charger. If you photograph during the day and use up most of the
two batteries, you put the one from the charger into your camera and put a
battery on the charger overnight. Then you have two fully charged batteries with
you the next day and you put the last battery on the charger to charge up while
you’re photographing.
Use a Tripod
The best way to become a better photographer is to use a tripod. I’ve said that
to any number of people over the years and I still stand by it. Using a tripod
does a couple of things. First, it makes your camera steady and stable so you
take razor-sharp pictures. Second, it forces you to slow down a little bit. Just
taking out a tripod and setting it up slows you down and makes you look a bit
more critically through the viewfinder as you compose your image. Most of us end
up not using tripods because they have a reputation for being big and heavy and
cumbersome, but if you have a compact digital camera, you can use one of the
ultra-lightweight, compact models that are available and reap the benefits.
There are plenty of instances when using a tripod simply isn’t possible, but if
you get in the habit of using one as often as you can, you’ll find that all of
your pictures will improve.
Slightly Overexpose a Subject to Reduce Blemishes
If your portrait subject suffers from skin blemishes or wrinkles, you don’t have
to wait until you get the image in Photoshop to make his or her skin look
better. Slight overexposure of your subject can reduce those unflattering
details. Overexposure often results in a lack of detail because the camera is
recording an excess item_price_1 of light off of your subject. In this case, this is
exactly what you want. By overexposing by two-thirds of an ƒ-stop or more,
the subject becomes brighter and the contrast is significantly reduced as are
the blemishes. Different skin colors as well as lighting conditions will
determine what item_price_1 of overexposure is necessary, but by using a digital
camera’s LCD display, you quickly can determine whether you’re increasing the
exposure by too much. For the best results, bracket your exposure so that you
have some comparison to choose from when editing the portrait.
Use an Off-Camera Flash
Using a flash off-camera allows you to shape the light around the subject. An
on-camera flash often results in a flat look to an image. While it’s quite
effective in eliminating harsh shadows that may appear beneath the eyes and
nose, there’s a noticeable drop in contrast and texture. An off-camera flash
allows you to create a sense of depth. A flash held off to the left results in
the light “wrapping” around the subject. If your camera has a hot-shoe or flash
sync port, you can tether the flash to the camera using a sync cord. A TTL-sync
cord maintains most of the camera/flash controls, including through-the-lens
flash metering. If you’re using a standard sync cable, exposure will have to be
determined manually or by using the flash’s auto metering mode. You also can use
an auxiliary slave flash. Make sure the slave flash is designed for digital
cameras. Digital cameras often use a pre-flash to calculate the correct flash
exposure, which may lead to the slave firing prematurely. A slave designed to
work with digital cameras will provide accurate sync.
Mega Pixel Madness
Mega pixel escalation is the name of the marketing game. How many mega pixels do
you really need? It all depends. Mega pixels aren’t an arbitrary indication of
quality—they mainly tell you how big a photo can be from the image file. If you
make a 4x6-inch print, 2, 3 or more mega pixels largely will give the same image
if other things like the lens and internal processing chips are the same. A
2-megapixel camera will give excellent 4x6- and 5x7-inch prints. At 3 mega
pixels,
you gain size so that superb 8x10- and 11x14-inch prints can be made; 4
mega pixels give you larger prints yet, as well as the ability to crop into this
larger file to still make excellent prints. You can crop a 4-megapixel file
considerably to make a 4x6-inch print and still have it look great.
Selective Focus Effects
Small digital cameras have short focal-length lenses. They have an inherent
tendency to give a greater apparent depth of field, so selective focus effects
(where the subject is sharp and everything else is soft) are harder to do. To
get this effect, there are two approaches. First, shoot as much as you can at
telephoto, zoomed-in focal lengths and back up to get your subject in the frame.
Telephoto settings have less depth of field. Second, use a neutral density (ND)
filter so you can shoot at the widest lens opening possible (the smaller numbers
such as ƒ/2.8 or ƒ/4) with your camera. Wide lens openings give less depth of
field.
Try Unusual Angles
If we look at our images, we may see that a great number of them are shot with
the camera at eye level. A whole new world can be opened to us when we pull the
camera away from our face and try different compositions and angles. A
great way to experiment is to focus on a single subject and try every angle and
position you can think of. Position the camera at various heights above and
below your subject. Tilt the camera slightly to the left or right. Start with a
wide shot and slowly move closer until you’re filling the frame with some
details of your subject. You’ll soon discover that there’s more than one way to
take a picture of any subject. As you review your photographs, you’ll find that
angles and camera positions you normally wouldn’t try add an interesting and
dynamic quality, even to a static subject.
Sharpen Your Files
Due to the way in which digital cameras process captured images, photos taken
with a digital camera benefit from sharpening. You want to increase the contrast
of edges in your image. For best results, use the Unsharp Mask filter. In
the Unsharp Mask filter dialog box, set the item_price_1 of sharpening to a high
percentage, starting between 100% and 200%. Next, set the radius to a low
number, around 1 pixel. Finally, adjust the threshold setting to 0. Have the
Preview option selected and view the image at 100% so you can see how the
adjustments affect your photo. If noise begins to appear in the continuous-tone
areas of the image, reduce the radius or increase the threshold in small
increments until the noise goes away. If you don’t have an Unsharp Mask
filter in your software, use whatever sharpening filter is available and apply a
light to moderate item_price_1 of sharpening. If the image starts to look funny,
you’ve sharpened too much.
Turn on the Flash During the Day for Fill
When you see a professional photographer working, you’ll notice he or she uses a
lot of flash. It’s an easy and highly effective way to dramatically improve your
pictures. Flash helps to soften or completely eliminate harsh shadows and adds
emphasis to the main subject in your shot. This is especially useful when you’re
taking pictures of people.
Continuous Shooting Mode for Portraits or Close-Ups
A camera’s continuous shooting mode was designed to help capture fast-moving
action. Yet, it’s a great tool for shooting portraits or close-ups because it
can help to ensure a sharp picture. Anytime you depress the shutter release
button, slight movement occurs, which can have an impact on the image. This is
especially a risk when working with a very shallow depth of field or a
relatively slow shutter speed. By using the continuous shooting mode, the camera
takes several almost identical pictures in quick succession. The vibration may
impact the first shot, but the subsequent images are noticeably sharper. The
trick is to maintain pressure on the shutter release button while you’re taking
the pictures. Although a tripod is always preferable, this camera feature
increases the chances of having a tack-sharp image.
Long Exposure Effects
Long exposures can give moving subjects a beautiful, soft and flowing look, from
water to cars on the freeway. However, this can be a problem with small digital
cameras with lenses that only stop down to ƒ/8 or so. You never get a slow
enough shutter speed to really see the movement effect. Try using a neutral
density (ND) filter. You’ll probably want at least 8x strength; for a shaded
waterfall and an ISO 100 setting, this typically will give about 1/8 sec. at
ƒ/8. This starts to show movement. Use two filters for even slower exposures.
Singh-Ray has a new variable ND filter called the Vari-X, which allows you to
adjust its strength.
Apply Unsharp Mask to a Separate Layer
Every digital image requires a degree of sharpening, whether it’s produced in a
digital camera or scanned using a film scanner. As a result of the image being
digitized, a slight loss in sharpness occurs. The Unsharp Mask tool found in
most image-editing applications is one of the best ways to achieve this. While
other tools sharpen an image globally at a fixed item_price_1, an Unsharp Mask
provides individual settings that you can adjust to customize the results.
By creating a separate layer for the application of the Unsharp Mask, you
provide another way of adjustment beyond the tool’s settings. You can choose
settings for a high degree of sharpening, but then reduce its effect by slowly
reducing the opacity of the layer from 100 percent. You can quickly see the
before and after effects of the unsharp layer by enabling and disabling the
layer in the Layers palette. You even can apply different degrees of sharpening
to specific parts of the image by using a Selection tool. In a portrait, for
example, you can select the eyes and lips for sharpening and create a layer.
Another layer can be created for a slightly lower item_price_1 of sharpening of the
hair and clothes.
Preset Exposure and Focus to Reduce Shutter Lag
One of the chief disappointments for many photographers when they first use a
digital camera is the lag time between the moment when the shutter release is
depressed and the instant when the image is captured. This lag time is the
result of the camera going through a number of processes, including the
charge-up time of the camera’s recording sensor, finding focus and exposure
metering. There’s nothing we can do about the first of these—it’s something that
undoubtedly will be worked out as the technology progresses. However, we can
reduce shutter lag by presetting our focus and exposure. First, compose
your image; then depress the shutter release button halfway and hold. This will
cause your camera to set the exposure and focus based on your camera’s metering
and focus mode. Some cameras offer a separate button to lock exposure or focus;
you can use these options if available. With focus and exposure locked, wait for
the decisive moment and then fully depress the shutter release. You’ll find that
this approach can cut shutter lag time significantly.
Choose a Self-Assignment
Every photographer periodically falls into a creative funk. Rather than shelving
the camera, it’s the perfect time to challenge yourself by creating a
self-assignment. By choosing a simple photographic task, you not only engage in
an exercise that will sharpen your photographic skills, but you’ll bring back
the fun of shooting, too. Choose a single color or shape or subject and
shoot nothing else for the day. You’ll become more aware of your surroundings as
you search for things that fit your limited subject matter. It’s important to
keep your equipment simple: a single camera and lens. A compact digital camera
is even better as your mind will focus on what’s in the viewfinder rather than
camera settings. If you prefer your SLR with a zoom lens, try to limit the lens
to a single focal-length setting. If you prefer wide-angle, shoot instead at the
telephoto position. By doing something different, you’ll discover
something new, and you’ll reintroduce yourself to the excitement you experienced
when you first picked up the camera.
True Infrared
Black-and-white infrared has long given a wonderful, almost exotic look to
scenes. Skies turn dramatically black, clouds pop out in white, trees and other
vegetation turn a pale gray or white, and haze disappears. Film was so tricky to
handle that infrared was hard to do. Digital camera sensors actually are
sensitive to infrared light. Most high-end cameras, though, have a cut-off
filter built in that limits infrared light to the sensor. But on
low-priced cameras, there’s usually none, so the camera can actually be used for
true infrared photography. Just buy an infrared filter (several filter
manufacturers make them) and hold it in front of the lens. The filter is black,
but the camera usually will compensate. Exposures tend to be long, so use a
tripod or other support. Set the camera on black-and-white, if you can
(otherwise, you have to convert in the computer). You may need to do some
lightening in the computer, but the end result is great.
Place Your Subject Where the Light is the Best
Photography is dependent on light, but a great image is dependent on a
photographer’s awareness of light. If you take a photo of a brightly painted
green door in the shade, the image is significantly different than if you shoot
that same door being illuminated by a setting sun. The difference in lighting
creates two distinctly different images, one of which likely will be more
dramatic and satisfying. Yet, late afternoon isn’t the only time to create
great images. Take the time to see how light is falling around you. Maybe a
shaft of light is passing between two buildings and shining on a busy sidewalk.
Maybe sunlight passing through the leaves of the trees is creating a fascinating
pattern on the ground. Once you have the light that you find interesting, you
may want to move your subject into that light. By making your search for great
light your priority, you’ll increase your chances of creating a dramatic and
stunning image.
Use White Balance Settings to “Filter” Images
Filters have been a creative control for photographers for as long as there has
been film. Digital cameras allow the use of conventional filters just as their
film counterparts always have, but digital cameras also have a built-in tool
that can be used the same way, and that’s white balance. By setting white
balance manually, you can give a scene a “warm” or “cool” look. Try using the
cloudy day setting to “warm” your shot and the sunset selection to “cool” it.
(Be sure to consult your camera’s manual, as different manufacturers use
different terms for the white-balance controls.)
Bracket Your Exposures
If you’re not familiar with the term, bracketing refers to taking multiple
exposures around the one the camera’s internal meter suggests. In-camera light
meters do an excellent job, but they can’t “think.” Occasionally, the in-camera
meter will generate an exposure that ignores an element in the frame that’s of
special importance to you. By bracketing, you ensure that the critical subjects
are properly exposed. In the film camera world, this was an expensive
proposition, but with a digital camera, it’s easy to bracket and discard the
images that aren’t right at no cost.
Frame Your Prints To Preserve Their Life
Inkjet prints are infamous for fading quickly. While ink and paper manufacturers
continue to make great strides in improving the life expectancy of inkjet
prints, it’s a good idea to protect your favorite images from the elements.
Sunlight is one of the chief enemies of print longevity. Gasses in the
environment also can be very detrimental to your prints. The best way to protect
them is to mount and frame them under glass. Choose acid-free matte papers and
mount your prints with “archival” tape. UV-reflective glass also is preferable.
Once framed, hang your prints away from direct sources of light. Protect your
prints, and they will last much longer than if left unprotected. Of
course, one of the great benefits of digital photography is that you can always
make another print easily in the comfort of home if a favorite image begins to
fade or color-shift.
Elegant Border
One way to make an elegant-looking print is to add a thin black line as a
border, a classic way of presenting images. There are several ways to do this.
The easiest is to make a selection of the entire image (Select/Select All, or
keyboard commands, Ctrl or Cmd A), then change the selection to a border
selection. (In Adobe products, this is in the Select Menu under Modify; in Ulead
Photo-Impact, this is in the Select Menu under Border). In Jasc Paint Shop Pro,
you can go directly to borders under Image/Borders. The size of the border to
use depends on the size of your photo and your taste. Try something in the
4-pixel size to start. Then fill with black, deselect and you’re done. For more
flexibility, you can put this border on a separate layer.
Carry a Towel
In The Hitchhiker’s Guide To The Galaxy by the late Douglas Adams, a towel was
described as the single most useful item one could carry. While that may be a
bit of hyperbole, there’s no question that a towel has uses that extend far
beyond its mundane appearance. I recommend that a white towel be a permanent
part of your camera gear. You can use a towel for wiping down wet or dirty
cameras, you can sit on it when the ground is dirty, and a white towel can be
used to easily set white balance in tricky situations or when you want to create
a special effect.
Get Bigger Prints with Less Resolution
You probably know that the generally recommended image resolution for making
prints is 300 dpi. Setting your images to this resolution will always deliver
high-quality prints. What you may not know is that you often can get away
with less resolution, thereby allowing you to print your images larger. Some
digital images, especially those from digital cameras (as opposed to scanned
images), can make excellent prints at resolutions as low as 200 dpi, allowing
you to increase your print size by a fair item_price_1. For example, an image I
recently captured with a 4-megapixel camera delivered a 6x8-inch image set at
300 dpi, but jumped up to an 8x10-inch print at 240 dpi and a 9x12-inch print at
200 dpi. Try setting your image resolution to 240 or even 200 dpi and make a
test print; print the same image with the resolution set to 300 dpi and compare.
You may be pleasantly surprised to notice very little, if any, difference in
image quality between them.
Bracket Your Compositions
You might already bracket your exposures. We also recommend that you try
bracketing your compositions. By this, we mean experiment with minor or even
dramatic changes in the way you frame a given subject. As photographers, when
we’re drawn to a subject, we usually have an initial impulse that guides us to
our composition. Many times, this impulse leads to a fine image, but there are
countless other images that could result from the same photo opportunity.
Bracketing your compositions is a way to move beyond your first view of a
subject and explore other ways of presenting it. By trying several compositions,
you have a good chance of finding an even better photograph than the one you
originally intended. You also get the opportunity to improve your photo skills
by challenging the almost automatic response that we develop as photographers
over time. It’s easy to get into a compositional rut, and this is a creative way
to break out. Think of it as “sketching” a subject from as many angles as
possible. Thanks to digital cameras, you don’t have to worry about wasting film
with such an exercise. Shoot as many images as you like until you feel you’ve
exhausted the possibilities. You can always delete the shots that don’t work.
Archive Images Immediately, Burn them to CD or DVD
Workflow is important when you use a digital camera. If you don’t develop good
habits, you can easily lose images forever. I like to download my images from
the memory card to a folder on my computer desktop. Then I do a quick batch
rename (with an image-management program like ACDSee) on all of the images to
get rid of the cryptic name from the camera. Typically, I don’t even try to edit
the pictures at this point. Once they’re renamed, I immediately burn all of the
images to a CD or DVD. That becomes my fail-safe backup copy of the images. Only
after I confirm that the images are safely saved on the CD or DVD will I erase
the memory card. I adapted this workflow after losing a number of images to a
computer crash—never again!
Exposure Compensation
Most consumer grade digital cameras will not allow to set exposure time.
However, you may have an exposure compensation feature, which allows you to over
or underexpose your photos. This could be handy for taking some pictures under
low lighting, or bright lighting conditions.
Know Your Camera's Limits
Read the manual. Become familiar with all aspects of your digital camera's
features. Experiment. This will eliminate fumbling to figure out a particular
feature, perhaps missing the perfect shot!
Shoot at High Quality
You can squeeze more photographs onto a memory card by adjusting the image
quality. Lower-quality settings apply higher item_price_1s of JPEG compression, which,
loosely defined, reassembles an image's pixels into a grid of square blocks.
This reassembly saves space, but it makes the image look less natural as well.
Most cameras let you select from three compression settings, usually defined
using comparative terms on their settings' menus. For example, Kodak uses the
terms Best, Better, and Good, and Fuji uses the terms Fine, Normal, and Basic.
Sometimes they vary on this theme a little. Epson, for example, uses a series of
stars. Whenever possible, stick with the highest-quality setting. If you
desperately need to squeeze more images onto a nearly full card, switch to the
second-highest setting. But don't go any lower than that, if you do, your
pictures will suffer.
Buy as Much as You Can Afford
This isn't saying that you have to run out and spend $500 or $1000 on a
camera. But if you buy a basic one, it may not provide you with all of the
features that you require! Having said this, there is nothing wrong with
purchasing a basic digital camera, and upgrading as your needs grow.
