If you're one of the lucky few for whom everything is going just right in your photography, then read no further. If on the other hand you are like me and feel your photography could always use a hand, here's some exercises you might consider trying.
1) see how creative you can get photographing an egg. It's rounded and slightly dimpled surface responds well to lighting, shadows can be very useful, you might need to figure out how to stand it on end - of course it's been done before - this is about being creative, not about selling photographs. Go for it.
2) Try some night photography. If shooting digitally, you are really in the money here as light meters are sensitive enough for streetlight photography, distracting backgrounds by day can be hidden. You might even see what you can do without a tripod.
3) Even though your interest lies elsewhere, choose subject matter foreign to your experience - normally shoot landscapes - make a serious attempt at photographing portraits or even nudes. Normally shoot sports and consider landscapes boring, well guess what, here's your chance to prove yourself wrong. You might want do do a bit of looking at good images in that field before you head out, but don't try to duplicate the work you have seen. Normally shoot car races, how about really challenging yourself with birds - now you have to fast AND sneaky.
4) Whatever your interest, what about coming up with some really good self portraits - after all the price is right, you can hire the guy for the price of a beer or two. Actually, the images might be better after the beer - test the theory.
5) How about going out for your usual subject matter but hobbling yourself in some way. For example:
- shoot landscapes without your tripod
- only take one lens, at a focal length you don't normally use
- take a mini tripod and only shoot from 1 foot off the ground
- go out shooting with only a few exposures worth of film or memory card (here's your chance to use that 32 meg card that came with your camera)
Maybe you won't make any prize winning photographs, but I can't help feeling that it will give your creativity a boost and help your normal photography.
