WONDERS OF PHOTOFLASH
Photographers, that don't like only capturing reality but also experimenting on photography may use this extremely cheap and easy technique.
You take a sheet of color paper, tracing paper or a napkin and place it against the photo flash when taking a photo. And that's all! As a result you get a picture with a shade of the color you chose. Easy as a pie!
You should choose paper thickness yourself. But consider that the thicker the paper is the less light from the flash you will get. Try different variants, watch the changes and choose one that fits you best. The same thing is with the color you choose - everything depends on your imagination. But be careful and don't place the paper too close to the photo flash, (there must be a gap, at least small one between the flash and the paper!) otherwise it may damage your flash.
Using this technique you will get a wide range of opportunities to create. For example, you're photographing some glittering object (ice statue, falling water etc.) - be prepared to unpredictable results.
Sometimes a small flash synchronized with the camera in your pocket can help vitally when the daylight is too rough and you need to emphasize the shadows. It's very easy: a small flash, a camera, an object and a sheet of paper or a plain napkin. Close the camera's photoflash, place the small flash in the wanted direction, cover it with a few napkins... and you get an outstanding effect of dispersed lighting! And if you have a colorful napkin - you will recieve a number of vivid effects easily.
Another one effect. A sheet of paper, folded in four or six fastened onto a powerful photo flash with a common elastic band will allows you to direct light onto the ceiling. this gives you an effect of smooth lighting in a dark room. But the ceiling shouldn't be too high and your flash too weak for a proper effect.
