Many studies have used cameras to investigate animal colour patterns, but most fail to test their digital Camera manuals may state the level of compression used on different settings, and image software should also state the from raw digital TIFF file images and the nominal reflection value, showing a curved relationship for the R, G, and B	./cache/work_qmfr2vpmjrh6da57h42olu4ggy.pdf	./txt/work_qmfr2vpmjrh6da57h42olu4ggy.txt
