My only thought is this: If they wish to see the finished product they dont get to see it without a large water mark until you have been paid

I have 3 quick ones.

1: Taking it on a nice camera doesnt automatically make it a super amazing great picture. Yeah its better than a smartphone, but so is everything compared to the lowest bar. A good picture will be produced, but the best ones require good color grading and a good camera + lenses.
2: Photographers who block the path. I get it, especially if you have a client. Trying to get the pictures done while there is light out still, but the rest of us want to walk by you to get past, and the people who arent taking pictures do too. (I do live near a place where a lot of people like pictures taken so it may be a local thing).
3: Adobes Behavior as a company. Fuck adobe.
