Photoshopping it would indeed have been easier and faster, just like using triggers, clicks and piles of punch-ins like everyone does would have made our album much easier to make. Tech provided shortcuts and trickery has really degraded the arts. It's not just the product of the work, it's the heart that went into it. That seems to have gotten lost along the way when computer tech exploded.
Will many, if any, know the amount of time and work that went into the photo, rather than it being photoshopped? Probably not. Sadly, most challengjng things in art that are actually accomplished now days are assumed to be fake to a large degree. But, that doesn't change the fact that going about your art with less shortcuts and more honest work puts you in a different mindset, makes you appreciate the art more and inevitably improves your art.
