Well, as near as I can tell, the picture presented is not doctored after it was converted or created in digital format, or they did a very good job. Mistakes typical to doctor jobs, such as inconsistent pixellation are not present. That does not mean that the image was not originally staged or that an original film photograph wasn't doctored and then scanned into the computer at a less than ideal resolution as a means to help cover the doctoring.
So y'all have mentioned some giant moose being killed, but where has this appeared in print?
