Please make a photographic wet print from the negative to see if the image still holds up!!!! Your image is artistically fantastic. I am not sure that you could do this in the darkroom; this in my opinion makes it a digital image and not an analog image (i.e. the purpose of this org.); Therefore, the only way to prove it is to take that negative and chemically develop, stop bath, fix and tone it and then scan the finished print. Only make adjustments to make the scanned image resemble the print. This would give the image "credibility" as a traditional photographic print. Otherwise, this is a digital image.
I would like to print this in the wet darkroom, but I don't have access to one at this time. Still I'm confident that this photograph could be done in the wet darkroom as well, and I do not agree that this is a digital image like from a digital camera. The scan is based on the negative, just as a traditional print would. All the information is in the negative.
