To me, exceptionally creative.
I’ve done a fair amount of Photoshopping, and some composites with layers. However, I think it would be very time consuming to accomplish the effect with layers, so that it had the same look.
So yes, it would save paper.
But … my speculation is that the actual art work would have a very, very different feel, in person. We have to use our imagination from the small JPEG’s from DPR to visualize the real art.
There would also be a “tactile texture” as you handled it, that would be missing from a 2D print.
Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
