I guess maybe it could be worth clarifying your copy, but who'd care? I do street work when I do it because I like meeting people and because it makes people smile. If I wanted money also out of it, I'd more likely just drop my hat on the sidewalk or something.
I still don't see why the comparison page (the one originally linked here, the iPhone 16/mirrorless shootout) treats variations in pose and composition as equivalent with those caused by camera physics, which was what originally caught my interest in any case.
Another use-case perhaps in your case is to do it for free and do higher volume and market your money-making services? I agree that it is fun and mood-lifting to take portraits, but also it would be cool to make it sustainable.
but yeah overall Candid9 is a hammer looking for a nail right now.
I don't think I have specific questions now, but I'm excited for the kinds of interactions it can spark. I mostly imagine getting lost in a sea of QR codes if it is not managed well. I was going to try to composite an extra copy for photographer reference.
