So a video i have been meaning to make for a while now... All about why paintings look so grainy in photos and better in person.
seems like a simple thing, but so many people don't actually know this.. or realize too late AFTER they think they ahve finished the painting.
Its always a good idea to take photos of you artwork as you go.. and THIS shows you one very common thing that it can pick up on.
not super useful if you are doing big think impasto pieces. But for my art - super useful.
