I've been doing some research to try to figure out why more people do not store high-resolution image files as PNG-24. PNG has exactly-reversible, lossless compression, it is a net-friendly format so any web browser can view it, and it supports full transparency.
I've seen several people say that TIFF has a "higher quality" than PNG, but no one provides any details on exactly how it is of higher quality. PNG-24 is lossless, so when you "Save As" a TIFF to a PNG, how exactly are you losing quality?
