So I work for Delaware Camera. Everybody knows that.
The regional manager just went to a trade show, and came home full of awesome ideas. About 5 years ago we used to offer classes and seminars and stuff, how to use your camera and how to take pictures of this or that etc. But the manager was the only one teaching them and he got really burnt out on them. (He actually has social anxieties, kinda, and it really took a lot out of him to do.) So we stopped doing them. But the show was all indie camera stores, and the successful ones all had a healthy class schedule; it's what sets us apart from the "I Dunno It Says Camera On The Box" big-box stores, where you buy a camera and can't figure out how to use it and bring it in and they stare at you like you're nuts for expecting them to have the slightest clue.
So we want to start having classes again. (I might teach some!! Squee!)

I'm wondering-- what classes would y'all attend? Are you interested in learning about photography and cameras? Have you ever wished you knew how to take that perfect picture of something? (If so, what?)

I was thinking a seminar on "How To Get Not-Totally-Shitty Pictures From Your Camera Phone" would be kinda neat, but the problem is, well, most camera phones suck, so the class would mostly consist of "Ok, so stand really really still, and preferably the thing you're photographing is really well-lit and not moving. Oh, it's dark and moving? Well, you're fucked." But still, it's an idea.
I hope you have better ones...
