So here’s the “base plate” i usually start with camera raw filter or some LUTs to fine tune the lighting and color to how i want it, takes a while to do granular changes in blender so i prefer to do it in photoshop.
Then go in and manually fix exposure in places for example the subject matter is very washed out so painting some fog behind the ship to break up the layers and adjusting exposure to make it pop.
Then some photobashed smoked and FX, then really i just bust out the paint brush on areas of highlights cause thats where the main focus will be, silhouettes and lit surfaces. the ship didnt need much cause thats where i spent most of my time.
But yeah i use a textured brush to get some of that painterly feeling but again you only have to do it in a few specific areas the rest of the comp is just eye rest and no one would ever notice if you did anyways.
