In this video Adorama’s expert David Berman shows how you should properly gel your speedlights.
The most important aspects are:
- Make sure that the gel covers the whole reflector of the flash
- Note that the exposure affects the saturation of the colors caused by geling. -2-3 EV underexposure can give you awesome results
- Make sure that the surface lit by the gelled flash is not lit by other – white – light, otherwise the colors will be less saturated.
