I've already posted something for this week's challenge, but I would love some technique advice. It's is unrelated to my challenge submission, don't worry.

Any advice on how to keep your camera out of a reflection of a convex or concave reflector and still keep the subject in frame? I have no extra equipment like a tripod. Any thoughts would be helpful... (To beat you to the obvious - I KNOW I need a tripod -- this question is more how to deal without one)

One of the techniques that are used in a studio is a "white box" or "black box". This is as simple as a couple of sheets of cardboard or foamboard that has been painted all white or all black.

The subject is placed inside the box, and a hole is cut for any lighting sources as well as for the camera lens.

The shot taken then only has the potential of including the lenstip and the lighting sources. Then the trick is to pick the incident angle so that your camera isn't captured.

In the field you can do variations on this by opening one or more edges of the 'box'. the remaining boards become a 'blind' for your camera.



The simplest technique though is to put your camera or yourself into an exposure zone that the capture device either drives to shadow or blows out as highlight. One way to do this in daylight is to play with your exposure settings so that what your meter says is the 'correct exposure' you then under or overexpose by 5 stops. You just need to be careful that you and your camera are darker or lighter than what you want to capture at the edge of the exposure range by atleast 1/2 a stop.
