Photos and Sketches
Remember that photos need not meet any particular quality standards; they will be examined only for any distinguishing characteristics that may help confirm a species ID. In many cases, a poor photograph is better than none at all and may provide the evidence that clinches a decision.
Digital images should not be significantly edited. If you made field sketches, please include one or more digital scans as these can be tremendously useful, even if you don't consider yourself to be a good artist!
