While I don't shoot nearly as much macro as many of the photographers in this group, I find this whole subject fascinating. Would I trust an AI-built app to handle focus stacking? Absolutely, provided it delivered better results than the tools already available. I don't particularly care how the software was developed. I care about how well it works. As far as having AI edit my photographs, that's a different story. I enjoy the editing process far too much to hand over creative control. For me, editing is as much a part of photography as pressing the shutter. The legal question is interesting, although I suspect it's more complicated than it first appears. AI development has already raised enormous questions about intellectual property, particularly when it comes to training data. But recreating a useful function isn't necessarily the same as copying someone's code. I imagine we'll see plenty of legal arguments over where those boundaries fall. I'm particularly curious about your focus-stacking app. How well did it work? Did you find it genuinely competitive with existing software? I've actually been experimenting with something similar, although for a completely different purpose. I built an app to help scout photography locations. I've loaded approximately 160 locations within a six-to-eight-hour drive of my home in Vermont. It still needs refinement, but I love having a tool built around my particular needs. Nothing commercially available gives me quite that level of specificity. As for AI in photography generally, I think we're well past the point of debating whether it's going to stick around. We can love it, hate it, or fall somewhere in between, but it's here. I already use and appreciate quite a few AI-powered features in photography software. The advances in masking and object removal have been remarkable, and they've made my workflow considerably more efficient. Where I draw the line personally is using AI to invent things that weren't there. But then, that was never the kind of photography I practiced in the first place.
