______________________________________________________________
Tip: For subject-perspective problems,
back away and use telephoto
- When you shoot tall subjects, such as
buildings, at close range, they can look as if they're ready to collapse in on
themselves due to perspective problems. To straighten things up, move away
from your subject, and then use a telephoto lens or mode. You'll straighten
the sides of your subject and avoid time-consuming work in a photo-editing
application.
Tip: Study your background with care
before you shoot portraits.
- When framing casual portraits, you should
take care there isn't anything that appears to be visually sticking out of
your subject's head. Tree limbs, signs, light poles, and flowers, to name but
a few things can distract from the strength of your image. When framing your
image, check your viewfinder or LCD preview before you shoot. When necessary,
move either yourself or your subject to a simple background that will
emphasize your subject, not the background.
Tip: Use a quick release tripod for
set-up speed and convenience.
- Although camera tripods come in many styles
and sizes, they all operate pretty much alike. You mount your camera on the
tripod head, set the length of the legs, adjust the framing of your camera,
and shoot. While tripods are great photo accessories, they also take time to
use. One way to speed things along when shooting is to use a tripod equipped
with quick release head mount. Before you begin shooting, you attach your
camera to a special mounting plate. When ready to place your camera on your
tripod head, you flip a lever to lock down your camera, and you’re ready to go
in a few seconds.
Tip: Image stabilization is now
available on many on digital camera models.
- Image stabilization, which has been a
feature of video cameras for years, is beginning to make its way onto the
digital photography market. It works by using complex optical designs that
compensate for camera movement caused by the photographer. Image stabilization
works well for steadying shots taken at a high zoom factor, a problem that has
been plaguing digital photographers for some time now. The drawback is more
expensive lens elements and increased power consumption. However getting a
clear shot every time certainly can make it worth the extra expense.
Tip: Know what the Raw file format is.
- When most digital cameras capture an image,
the image data is sent to the camera’s processor which compresses and then
outputs the date too a JPG or TIF file. However, many digital photographers
didn't like the idea of having their image data compressed, so manufacturers
have now begun to include a Raw file format as a file capture choice.
The Raw file format saves the image data in an uncompressed file format
directly from the image sensor. Raw files typically are smaller than TIFF
files, but require a special utility on your computer to interpret them, such
as Photoshop’s Camera Raw plug-in.
Tip: Pan action shots with your digital
camera.
- When you shoot a moving object, it's often
best to track the subject as it moves across the scene. This technique called
panning helps you to keep your subject in focus while blurring the background.
The effect also gives your image the visual illusion of movement and captures
the moment with greater visual interest. When panning with your camera, you
should be certain to keep your camera steady and level as you track your
subject.
Tip: Avoid the automatic power-off
hassle.
- Slam, and it’s a home run at a little league
game? Arrg! Your digital camera automatically powers off, and you miss the
shot. Most digital cameras have a setting that automatically turns the camera
off when the camera hasn't been used within a certain period of time. While
this setting certainly helps you save battery power, it can happen at the
worst moment. If you know there's a particular moment you want to capture,
sacrifice your battery life and turn off the auto power-off feature, and
remember o turn it back on after you've take the shot.
Tip: Know about the aspect ratio of
your digital images
- One surprise for photographers switching
from a film to digital camera is the size difference of the image. The frame
of a traditional 35 mm camera has an aspect ratio of 3:2, while one from a
digital camera is typically 4:3. This means that an image from a 35 mm frame
is longer than one from a digital camera photo. While this is easy to get used
to, you should keep this in mind that when composing your shots. You might
have to crop out some image information if you want to print to a standard
photo size such as 4 x 6 or 5 x 7, which works out to 4.5 x 6 and 5.25 x 7,
respectively.
Tip: Keep in mind camera temperature
changes
- In case you’ve forgotten, that camera lens
you spent so much money on is a big chunk of precision glass. Like most glass,
it can fog up quickly when exposed to drastic temperature changes. If you’re
traveling in the tropics for example, but staying in a nice, air-conditioned
villa, set your camera out on the balcony a few minutes prior to capturing the
first shot. Otherwise, you’ll find your lens has fogged up.

Tip: Use a color-reference card to
color balance your images
- There are times when you have to match the
colors in an image as closely as possible to those in the subject itself. An
easy solution is to place a color-reference card in at least one of your
subject shots, and then use the reference card later as a reference while
color-balancing your image using an application, such as Adobe Photoshop.
Tip: Take along a small printer on
vacation to make prints for your vacation friends
- A good way to make friends while you’re
traveling is to carry along a small dye sublimation printer. They only weigh
about two pounds and take up less space than an additional digital SLR. You
don’t need to have a computer in order to print photos directly from your
camera. Take a few snapshots of people you meet along the way and then give
them the photo the next day. You’ll instantly become a digital photography god
to them.
Tip: Make a CD of your vacation photos
for your vacation companions with your laptop
- If you’re taking your laptop computer with
you on vacation, you can impress your vacation companions by presenting them
with a CD of your vacation photos of the week. Just pop a few blank CDs into
your computer case before you leave and then burn all the good shots (you know
they can’t all be perfect shots, now don’t you?) onto the CD. Then, before you
leave, give the CD to your companions to remember their fun times. Trust us;
they’ll be amazed at your thoughtfulness.
Tip: Take advantage of your digital
camera’s exposure lock for improved exposure
- Many automatic cameras will retain your
exposure setting if you press the shutter button halfway down. To use this
feature, aim the center of your frame at the part of your subject that is
overexposed, press the shutter halfway, hold it, and then recompose the scene
and shoot. You should have improved your exposure.
Tip: Try infrared digital photography
for interesting shots
- No doubt, you’ve seen prints of infrared
shots done with a traditional camera and film. Way cool, yes? But did you know
it’s possible to capture infrared images with a digital camera as well? Yes,
and it’s easier than you might think. All you’ll need is an infrared filter,
your tripod, and time to test out your equipment for best results. For
specific information on which filters are best for your camera, consult your
digital camera user’s manual.
Tip: Transparent materials at hand make
for great digital camera filters
- While there are plenty of commercially
produced digital camera filters available, you might want to try using
transparent materials you find at hand the next time you require a filter.
Stained glass from a hobby shop, soda and beverage bottles, and even candy
wrappers are a few materials that make great filters.
Tip: Use flat lighting to your advantage
- Most often, photographers avoid flat lighting because it
decreases definition and texture in a subject. But you can use
flat lighting to your benefit. Whenever you want to shoot a
subject with small flaws, such as scratches, nicks, and dents,
and don't want to spend hours retouching it later, shoot your
subject in an open shadow with bounced flash or studio light.
Tip: Use your imagination
-
An old saying goes, "Some things are best left to the
imagination." You might say the same about capturing your digital
shots as well. If you sometimes allow soft tones, indistinct
subject definition, and misty backgrounds, you enable your viewer
to engage his imagination with your image, and in a sense, make
it his own.
Tip: Use your built-in timer for slow shutter speeds
- Image blur is often the result of slow shutter speeds. To avoid
the problem, a traditional photographer uses a cable release.
However, most digital cameras have no means of attaching a cable
release for that purpose. A simple workaround is to use your
built-in timer. Allowing the camera to settle for the 5 or 10
seconds of delay usually prevents the annoying problem of blur.
Tip: Use manual focus mode for critical focusing on macro subjects
- Shooting a subject close up can be a tricky thing, especially if
your autofocus mode just isn't cooperating and nothing you do
seems bring your subject into focus at such a close range. A
great way to work around the problem is to switch to manual focus
mode. Set the focus as close as your camera will allow, and then
slowly move your camera toward your subject until it's in focus.
You'll find it's often less frustrating than trying to find the
autofocus sweet spot that's eluding you.
Tip: Getting close-up shots with a flash
- If you like taking close-up shots
using the macro mode on your digital camera, you know that you built-in
flash can be too bright when placed so close to your subject. If
you're serious about your close-up shots, consider using an external
light source to the side or behind the object to help evenly light the
scene without adding any unwanted hotspots. You can instantly
check to see if you have the right exposure using your camera's LCD
viewer. If the flash is too bright, move it about a foot farther
away from you subject. Do this until the exposure is correct.
Tip: You need to clean your memory card too
- Sand is great for a sandbox and at the
beach, but not for digital cameras. Even a grain or two that gets
caught in the contact sockets of your memory card can cause problems.
Whenever you return from an sandy outing, check your card for lingering
sand and debris that may have found its way to your card. If you
do find a few grains, carefully dust them to the side, or use a blast or
two of canned air. If you use canned air, be careful not to blow
and jam sand into the socket holes. Always direct the air stream
across the sockets and never into them.
Tip: Don't forget about your remote control
- Some digital cameras come equipped
with remote control shutter releases. If yours has one, it's well
worth your time to learn how to use it. It's better than a time
delay because you can take a hands-off shot whenever you want. In
a situation when you're alone and have to control a reflector or a scrim
on a subject that's more than arm's length from your digital camera, you
can just press the remote button.
Tip: Title your vacation photos
- If you're in the habit of taking many
vacation photos, and then wonder months later where you shot them as you
review your photos, take a few seconds to snap a title shot for each
event you shoot. It's actually quite easy. If, for example,
you're shooting in a public museum, take a quick shot of the entrance
sign or guide brochure. If you're shooting scenes in a town, shoot
the "Welcome to" entry sign, town hall, or even a local store with the
town name in it.
Tip: Use manual mode for greater depth of
field
- Whenever you need a great depth of
field for a shot, use the manual mode. That way you can set your
digital camera's f-stop to its smallest setting. If you use your
auto mode, you'll get the aperture shutter combination your camera's
software gives you.
Tip: Set focus to infinity when shooting a
landscape through a window
- Sometimes when shooting a landscape
out a car or room window, your digital camera auto focuses on the window
glass rather than your scene. To correct the problem, set your
focus mode to infinity, and you'll never have that dilemma again.
Tip: Put a red dot on your memory card
- Do you have a problem remembering
which way your memory card fits in your camera? Even though you
can only fully insert them one way, you may sometimes flip it back and
forth while trying to rock it into place. If this is a problem for
you, take a red Sharpie marker and put a red dot on the side of your
memory card that faces you. Then, remember "Read Red Right,"
meaning when you can Read the Red dot your card is positioned Right, and
you'll have the problem solved.
Tip: Apply Velcro to the back of your lens
cap
- Lens caps aren't provided by camera
manufacturers simply for show. They help avoid fingerprints and
scratches on your lens. Since most digital cameras are made with a
fixed mounted lens, repairing a damaged lens means sending the entire
camera out for service. If your lens cap didn't come with a short
attachment toggle, solve the problem of lost lens caps with two
Velcro-brand dots. Glue one on the back of your lens cap, and the
other on your camera strap. Then, when you want to take a shot,
you can quickly attach your lens cap to your strap. It will stay
put, and you won't forget where you left it.
Tip: Use your exposure compensation feature
to correct for consistent problems with exposure
- If you consistently feel your images
are too light or too dark, or even if you prefer them that way, don't
forget about the Exposure Compensation feature found on most cameras.
Use it to override the default setting by up to several stops to suit
your preferences.
Tip: Use your self timer to prevent shaky
pictures
- The next time you're taking a shot at
a slow shutter speed, use your self timer to prevent blurry-looking
images caused by camera motion. Even when your camera is mounted
on a tripod, camera motion can occur, especially if you haven't set the
locks well enough, or if you're using a lightweight tripod.
Tip: You have what kind of brown spots in
your grass?
- Describing plant problems to a garden
and lawn expert can be difficult. This is especially true when you
can't take a problem sample with you. Take several shots of ailing
plants, bring your camera with you, and then play back your photos when
talking with your plant doctor. It should be very helpful as you
try to find a remedy.
Tip: Capture faces and names at family
reunions
- Family reunions are popular events.
If you have a problem remembering all your twice removed cousins or
great uncles, take a quick shot of your extended family members and
include a 3 X 5 name card. If you do this at the start of the
event and offer to email your photos to anyone who wants copies, chances
are you'll find little resistance from participants who are camera shy.
