The sRGB color space reproduces more vividly
for viewing on a computer monitor. Adobe
RGB would be the choice for inkjet printers and
traditional printing presses, which use inks that
can reproduce the wider gamut of this color space.
Exposure Numbering
For identification, the frames on a roll of
exposed 35 mm film are numbered from 1 to 24
or 1 to 36, depending on roll length. Negatives are
edge-numbered on the margins of the frame, while
slides have numbers printed on the mounts. Many
photographers assign a number or date code to each
roll, so a specific frame can be identified as needed.
Digital images are numbered by the camera’s
software. Each image is electronically tagged
with an identifying number that becomes a part
of the file and is usually used as the filename,
such as IMG_2237. Most cameras offer a choice of
continuous numbering of up to 9999 images or of
restarting numbering each time a new memory
card is inserted. Since continuous numbering
minimizes the possibility of images with duplicate
numbers, most photographers choose that method.
Physical Care of Your
Camera
Cameras and lenses are precision instruments
that can be damaged by rough handling or by
exposure to water, dust, sand, or other environmental
dangers. Protecting your camera from damage is
mostly a matter of common sense. You would not use
the camera in a driving rainstorm without some form
of waterproof covering, nor would you set it down in
the sand while shooting at the beach.
Wet-Weather Protection
Rainy weather can often allow you to make
good photographs. To protect both you and
the camera while photographing under rainy
conditions, use various forms of shelter—a building
doorway or porch, a vehicle with the window
rolled down, or an umbrella. See Figure 2-21.
When conditions are both wet and windy, however,
such shelter may not be enough to keep your
camera dry.
Better protection is offered by flexible plastic
housings that fit over the camera and lens barrel.
These housings do not cover the front of the lens,
since the material would cause distortion of the
image. The housings may have cutouts or other
provisions for using camera controls. See Figure 2-22.
An inexpensive alternative can be made
with a large plastic food storage bag and a
rubber band. For SLRs with telephoto lenses,
either a one-gallon or two-gallon zip-closure bag
is adequate. Cut off one of the bottom corners
of the bag to leave a hole approximately the
diameter of the lens hood. Place the camera in
the bag with the lens protruding from the hole,
then use the rubber band to secure the plastic
around or just behind the lens hood. The open
end of the bag lets you use the viewfinder and
operate camera controls.

delicate electronics from moisture on rainy or snowy days,
or when photographing from a boat or canoe. Various sizes
are available to accommodate different zoom lens lengths.
