As far as taking photos vs scanning, photography wins and here are my reasons why.
1. The colors are truer to the original artwork.
2. Large pieces don’t need to be scanned in sections and pieced back together in Photoshop.
3. Glare and some unwanted texture can be avoided with proper lighting.
For Skump the photo worked better but the texture remains. I don’t find it as intrusive and I can’t complain since I am happy with the original and the texture is part of it. If I buy this acrylic paper again I’ll get the smooth surface and save myself the headache. For the paper I have left I’m going to either work the canvas pattern into the piece or smooth it out with gesso and a palette knife.
