i have found shooting reflected images off of mirrors/glass and, to a lesser extent, water to be difficult in the sense that what my slide ends up as is far different from what i had burned in my memory during the shoot
specifically, on my last attempt i had tried to shoot a seaside reflection off of a glass door (at roughly a 45 degree angle). i set up with a tripod and cable release, and was darned sure that the dominant view from my/camera vantage was a striking (blue/green) sea reflected off of the glass. when i got the slide developed, the dominant effect seemed to have been one of looking through the glass door to the other side as opposed to capturing a reflection -- there was a mixture of that plus reflection which made the slide very difficult to clearly make sense of
understand this may be sketchy on details, and perhaps i should post an image, but in general how have others optimized results when shooting reflections
thanks, kipp
