Hey maru, thanks for adjusting that pic for me, that is much more as it looks in person! Adjusting photos is still a skill that alludes me. Nice to hear from you, I always inboxed chatting in the past and hope to see you around more on here!
If the image has something you know to be white, it is easy because some softwares are "one click" with those (so cheat and try to always have something white somewhere). Even with neutralish grey, it can be easy. If no such areas, it can be tricky as you have to estimate the colors and eyes-brain can play nasty games.
Haven’t posted in here in a while, but here is a dump of some of the stuff I’ve done in the last little while.
