Submission Guidelines for Photographs, Arcata High School, The World "The way we saw it"

The images should be in jpeg format (.jpg). The longest side of the photo should be a minimum of 1800 pixels for publication, but 3,600 pixels would be ideal. If you need to set a dpi, then 300 dpi is the minimum. The recommended bit depth for a black-and-white photo is 8 and for a color photograph 24. If prompted, the compression/quality of a jpeg image should be set to 10 Maximum.

On a PC, if you right-click an image file and select "properties," you will be able to view the dimensions and bit depth of an image.
