Never done any postwork on any of my renders. I always use 100% DAZ settings. You can get some really nice results with just DAZ, just need to learn how to use it.
Likewise.
I just use PS to remove any fireflies if I can't do that with DAZ or resizing, Spot Render pasting and add my signature.
Even if I spot some poke-through, I usually fix it in DAZ even if I also fix it with PS.
Although, I posted 1 render in this thread that I edited heavily (for me anyway) in PS because I couldn't get all the elements right.
Not to dunk on those that are amazing with their PS skills, I know there are things you just can't do in DAZ.
I just like to see direct results, maybe also post extra angles, maybe see the result and think I need to add something to the scene. I don't want to set up a scene in DAZ that I KNOW needs lots of work and then try to do it in PS.
Maybe it's laziness, but that's just me.
