Did you know that different types of light bulbs can create different color casts on your artwork?
Usually the most flattering light is daylight. Special daylight bulbs for photography are available. They can be a great addition to your indoor photography studio. It make take several lamps to get the results you want.
When I photograph my own artwork I find that shooting outside in natural light is often the best, easiest, and most economical solution. Shoot your images outside, out of direct sunlight- say on an overcast day or on the north side of a building when it’s sunnier (if you’re in the Northern Hemisphere). This should result in an evenly lit image.
Either way you choose to photograph your work, watch out for harsh glares and deep shadows. They can be distracting.
