If this isn't an original idea, please forgive me, but I've not seen this mentioned in numerous photo magazines, nor here. With my old film cameras, I long ago practiced until I could completely operate them in the dark. I've found that much more difficult with my digital Nikon SLRs. I got the idea of fastening a little button cell flashlight--like the ones made by Photon and others--to the adjustment buckle on the camera's strap. So far, I haven't noticed it being there, yet it is right where I need it if I'm shooting in dark place.
