Digital Photography

Week One Review


Resolution l.jpg

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 >150 dpi

You can get a bigger print with good quality by compromising on resolution. Walmart supplies a CD at 200 dpi.

Figure study l.jpg
Figure Study what your resolution should be:

A figure study captures the image of your subject in its entirety. Cutting off the hand in this image was an error. Figure studies don’t necessarily have to be human subjects. Any object can be photographed as a figure study as long as it is composed in its entirety.


Vantage point l.jpg
Vantage Point what your resolution should be:

The bear was actually a rug and the photographer laid on the ground to get a straight-on vantage point. Your position in relation to your subject can greatly affect the perception of the viewer.
