The best digital camera settings for high resolution photos start with
file resolution and compression, and four digital
photo exposure settings that are automatically set [AUTO], or adjusted
File Resolution and Compression. Both of these camera settings
determine the size of photos stored on your camera's digital media card.
A general rule of thumb is that the higher resolution setting with the
least amount of compression is the best for producing giclée
use the Canon Powershot A40 camera to illustrate this point. The button
marked Menu on the body of the camera displays the resolution and compression
settings. Select M2=1024x768, M1=1600x1200 or L=2272x1704 to produce
giclée prints. The larger (L) file size is best for large format
Powershot stores photos in a format that is dowloaded in JPEG file format.
Digital SLR cameras also offer RAW or RAW+JPEG file formats that are
best for producing high resolution prints.
to resolution, the Powershot A40 offers three Compression settings:
superfine, fine and normal. The size of the image saved with superfine
compression is larger, so this is the best format for producing high

your digital photographs for giclée prints.
Photo Exposure. There are four digital camera settings that
bracket exposure. AUTO exposure automatically sets all four. Digital
SLR cameras and some digital snapshot cameras also allow you to set
them manually to refine photo capture:
In the pre-digital camera age this was known as film speed. To capture
subjects in low light levels, increase your camera's ISO setting.
For instance, use ISO 64 for direct sunlight, ISO 100-200 for moderate
to cloudy daylight, and ISO 400 or above for interior photos. Note
that ISO can only be set when AUTO [P] exposure is not selected on
most digital cameras that offer manual setting features.
Or, the size of the lens opening when the digital scan is taken. The
SMALLER the f-stop NUMBER the LARGER the lens OPENING. Yes, a 4.5
aperture f-stop allows more light to reach the image sensor than an
11 apeture f-stop setting. Outdoor photos in full sunlight usually
require an aperture setting of 8 or above, and interior ones without
a flash (and enough indoor light) require 4.5.
SPEED. Yes, that's scanner not shutter speed. Since digital
cameras use digital image processors rather than film to capture images,
the amount of time light is exposed to the camera's digital processor
is the same as the shutter speed setting on film cameras. Higher speeds
= less exposure time, thus less light will reach the digital processor.
BALANCE. Typically set at AUTO, some digital cameras also
allow you adjust the hue of white to compensate for different lighting
[AUTO]. Most digital cameras have an automatic setting that
optimizes light exposure so ISO, aperture, scanner speed and white
balance are optimized based on the camera's built in light exposure
Setting Summary: Settings with accompanying low and bright light conditions:
setting = low light
High Scanner Speed = bright light
High Apeture (f-stop) = bright light
what is "good" exposure? Good exposure is a photograph
that exploits the entire range of white to black and the color spectrum
without loosing detail in the very dark or light areas of the print.
Most high end digital cameras and digital photo processing software
use the histogram to illustrate that range. Here is one example of a
bad exposure with it's original histogram, and how the photo looked
after correcting the exposure with Adobe Photoshop.
EXPOSURE is washed out. Note the dark end of the histogram
(the height of lines to the left) is weak as well as the light end (absence
of lines to the right). There is no detail in the dark, nor the light
areas of this photograph.
same photograph in which the range is adjusted to increase dark and
light areas during the digital photo processing phase of producing the
many deficiencies in the amount of light and scanning speed can be corrected
by the digital proofing process, it is far better to start with a photograph
whose ISO, aperture, speed and white balance have achieved consistent
exposure and a wide range of gradients from light to dark across the
color spectrum, similar to this photo taken at sunset when the sun's
light is fading.
