I think it's a question of adopting a gimmick for the short term gain of making a few extra dollars Vs. Investing in your vision and your brand- by investing in my brand I can gain clients that are excited about my the kind of photography I do, and know what to expect from me when they book me.
The gimmicky, novelty road isn't for me.
You can say an idea is not for you with dismissing the idea as a "gimmick" or a "novelty", can't you?
You talk a lot about "building your brand" and "gaining clients". But your strategy seems to be more about telling your customers what they need, not asking them what they want.
If one of your perspective clients asked you if you do photo booths, would you look them in the eye and tell them, "No. I think its a gimmick. I would rather be known for my superior images."
I doubt it. Because here's the real truth. There are probably 25 or 50 guys in your market that take images as good or better than yours. And if they offer the client more value, or more importantly WHAT THEY WANT, they will get the job.
I wish I had more competition like you.
