Sepia is a camera setting that takes out the little bit of coloring in a photo
Compare this photo (of my solar light experiments) with this photo:
Personally this is not the best example of when to use Sepia because you need a subject with high black and white contrasts to make it more outstanding.
My camera has the negative effect option (I have a Sony Ericsson camera phone and the newer models have more pixels available, mine goes to 8 megapixels)
When using the negative effect you need contrasts too.@Babyboomerjill
needs help in stopping window reflecting glare. Basically if you see your reflection that is an effect you want to avoid. You can set up your camera on a stand so that a window does not reflect the photographer in the photo but you will still see a camera and a stand. I may tomorrow when it is sunny try to do some experiments to block reflections.
