/ic/ - Artwork/Critique

Found out recently that 8-bit Integer color space sux due to noticeable posterization.

So let me ask what the best configuration is for:
>ICC profile?
ACES/Pro/WideGamut/Adobe/s/CIE etc. RGB or if you use XYZ fine too.
>ICC version?
v4 or v2.x?
>color depth?
8/16/24/32/bit?
>TRC? (gamma)
l-star/linear/standard
>document type for publishing
PNG/raw BMP/etc. Preferrably lossless quality
>document type for master
ORA/KRA/PSD/etc.

For me TIFF is pretty good due to: WSIWYG, alpha, layers, ICC profile, and lossless compression although it's not widely used or supported...

TGA and XPM are also fine.
so far JPEG and PNG just works but recently most online services lossly re-compress images over and over again and sometimes even delete the ICC profile like what most normie social sites and 4chan/imgur does to save server space (only if the image exceeds the file size range for decreasing server/cdn and client load).

Tips to avoid these problems and which artist sites respect the ICC and file's checksum?

Do not >>>/b/itchpost if you don't understand any of the shit we're talking about.
