O.k., so I've got FF running inside an old version of Photoshop (V5), and when I render to .jpeg at the highest quality setting, it's 1/3 the file size of a 100% render straight out of FF (stand alone). So my question is, why the difference, and what is the difference in halfway down to earth (non-techy) terms ?

on your full size render in stand-alone, how are you checking the file size, in ps v5?

When I hover the mouse over the file it tells the Kb/Mb size of the file, and it's a big difference, about triple.

----Just in the folder I rendered it into. Or when I right-click and check the properties.

ah, ok. sounded like you might were pulling it up in ps and getting the loss that way. seems no, though.

no clues then. sounds fishy.

Jffe, different programs have different compression algorithms. The 'Highest' setting in Photoshop may greatly differ from the '100%' in Filter Forge.

Jffe, could you post both Jpegs and an uncompressed Tiff/BMP of the original render?

----The .tif alone is 16mb, yer looking at anywhere from 25megs to 25megs for all 4 renders, can I just upload them to the forum here ??

I would also say that the "Full-precision color encoding" checkbox in FF's JPEG save dialog (which is enabled by default) increases file size a lot (around two times usually) for giving relatively small quality improvement when dealing with photographic or just any other non-high-contrast images (high-contrast synthetic images like patterns benefit a lot from that option on the other hand).

----And that is bypassed when FF is used as a filter/plug-in inside of Photoshop then I take it ?

----I tried it with a 600 X 600 image, and a 1200 X 1200 (100% synthetic images), and got right about 25%-30% filesize difference both times. The difference between FF stand-alone and FF inside Photoshop is about 300%+, waayyy bigger difference. I need to know why, and what the difference is.
