Resolution
What you are going to do with your digital
pictures dictates what your resolution should
be Display on website 72 dots/inch
(dpi) High quality prints 300 dpi If
you convert resolution from 72 dpi to 300 dpi,
your print size gets smaller. How small depends
on how many megapixels your camera is. A 3.1
megapixel camera will make a maximum of a 5 x 7
print at 300 dpi Good quality prints gt150 dpi
You can get a bigger print with good
quality by compromising on resolution. Walmart
supplies a CD at 200 dpi.

Resampling

• Resampling changes the pixel composition of your
  image. Most instances you will not resample when
  converting resolution or image size.

Uncheck for no resampling

Resembling II

• You may want to resample
• 1. If your image size is not large enough
  after you convert to the desired resolution.
  (limit size changes to 25 or less to maintain
  quality)
• or
• 2. You are making images smaller for
  display on the web. This is necessary to keep
  file sizes small and make web pages load faster.
• Note Because resembling always alters the pixel
  composition of your original image, you should
  always save resampled pictures by a different
  name, so you keep your original copy intact.

Elements of Photography
8
Visual Rhythm
Visual rhythm refers to repetitive patterns
within images. This picture has several.
9
Figure Study
A figure study captures the image of your subject
in its entirety. Cutting off the hand in this
image was an error.
10
Vantage Point
The bear was actually a rug and the photographer
laid on the ground to get the view. Your
position in relation to your subject can greatly
affect the perception of the viewer.
11
Balance
The position of the steeples compliment each
other and add balance to the image.
12
Contrast
Refers to the difference between the lightest and
darkest area of the image. The neck of the
flamingo is exemplified next to the dark
background.
13
Texture
Texture is often eye-catching and can be
manipulated to enhance the image as in the trunks.
