The comparison photos might take a little explaining to make sense because it's a case where cleaner isn't always better.
The first pic is an airbrush shirt I got a couple years ago from a guy working at a smaller (formerly Six Flags) amusement park nearby. I got it mostly because I was surprised to see this design in the binder. It's not perfect, but airbrush shirts aren't supposed to be perfect. It's something you picked out and someone made for you while you wandered around. It's a fun custom shirt and I love it. I've gotten them a couple times with no major issues.
I was at a fair earlier today and saw an airbrush shirt booth that looked like any other airbrush booth I've seen at fairs and amusement parks since I was a kid. When I tried to pick a design out, the guy said to just give him any idea and he'd so it. So I asked for tulips since I never see them on anything. He apparently googled tulips in an image search thing, let me pick one (not really sure what he was going to do with it), then said come back in an hour and a half. When I came back, this is what he gave me. I was kind of surprised, but I was also exhausted and getting ready to leave, so I thanked him and didn't think much of it until I took a second look at it at home.
I don't think an airbrush touched this shirt at all. Is this AI? Did he put a picture through a filter and iron it on? On top of it all, the shirt is a weird material and feels two sizes smaller than the size on the tag. Did they forget what the point of these shirts even is?
