I love PNG for many things. But when dealing with Raw portability sometimes
a Tiff is needed. The real challenge is what is your end goal and what are
you looking to do with it. I acutually use JPG to protect my images from
full theft because only i have access to the 100% RAW image. my Jpg's at
best go our as 80 of the original and at most 1/4th the resolution.
4000x6000 rendered to 1080x1920
