I'm taking pictures of DVD's to sell on eBay, and I get my refection in the pictures I take. How do I avoid this without laying the DVD flat and taking a slanted picture?
I am using a Nikon Coolpix S6100, point and shoot.
Blowing out your reflection on the DVD using flash is a viable option, assuming that doesn't also overexpose any details you need to retain/show (labels).
Other options that help are to reduce your reflection by shooting through an opening in a white sheet or similar to create a large/even white reflection... that will still leave the lens element as a distracting reflection. You can then make that even smaller by moving as far back as possible and using a longer focal length/zoom. And you can then angle the DVD slightly (or change camera position) so the small camera reflection that remains falls on a non-reflective area (i.e. on the label).
In other words, more than anything else, with highly reflective objects you create the environment/scene you want to record reflected in the object.
You can easily fix the slanted picture in post-production using the perspective correction tool of any good editor (Gimp, PS...).
Use a flash and 1/200 shutter speed.
The high shutter speed makes anything not lit by the flash unnoticeably dark. The flash hits the shiny DVD directly, so it doesn't need a lot of power, and thus doesn't backsplash a lot to the camera and photographer. It might also help to pull the camera back a bit and then zoom in a bit, to further deplete the flash's light splashing on you (see the inverse square law). A dark background for the product shot would help as well.
