the best lighting to use is sunlight
If you have a white poster board you can use it as it is and put a lamp close to it. You could also cover the poster board with aluminum paper and shine a flashlight or use the lamp with it.
Use a big piece of cardboard covered in tin foil its cheap and easy to use.
Flashlights work well.
sunlight and reflectors anything white nd shiny might work. also background and subject contrast might help.
