Light Orange Color Filter SCF-ELOR1 Dark Orange Color Filter SCF-ELOR2 Dedicated to the Canon Speedlite EL-1, the SCF-EL Color Filter Set is a pair of hard-type clip-on filters that help to warm the flash's cooler color temperature output to create a warmer aesthetic. The SCF-ELOR1 Color Filter is a light orange filter that merges incandescent lighting conditions for a warmer mood. The SCF-ELOR2 Color Filter is a dark orange filter that is useful for balancing out the red fogging typical of interior lighting, for more natural and realistic light quality. Both of the filters attach and detach to the flash head with a simple snap-on design.
