Most new digital cameras have a built in UV filter to eliminate
atmospheric UV (which causes confusion for those of us transitioning
from SLR's to digital SLR's). New digital cameras can be fitted with
Kodak Wratten 2A or 2E filters for UV photos not quite as
satisfactory as ones achieved with film. Older digital cameras that
do not have any internal UV filter, such as the older Canon
Powershot S3, can have the settings adjusted for very satisfactory
UV photos with a filter taped to drape over the lens. We have
several different cameras we have tried for UV and have consulted
tech reps at the manufacturer to obtain the custom settings that
optimize UV photography.
