Light diffusion is the key to a good macro or micro photograph. We never allow direct light from the source to come into direct content with the subject…. ever. This is because it direct light from the source will produce a significant amount of glare, which will degrade the overall quality of the image significantly. The solution is to shine light from the source into a diffuser so that the object being photographed is illuminated by reflected light only. This is the lighting technique we use, regardless of size, medium, texture, color, etc. Basically, it always works and the resulting pictures will be immaculate.
