Nikon SJ-1 Color Filter Set for SB-600, SB-800 and SB-80DX
The SJ-1 allows you to modify the flash output so it is matched
to the ambient lighting. This is especially useful for digital
photography where "white balance" can be maintained.
For instance, when using a flash under fluorescent lights
the affected area will be white, however the background will
have a greenish cast. By filtering the flash output to green,
matching the rest of the scene, the camera's white balance setting
can then be set to "Fluorescent".
The blue, yellow, red and amber filters can also be used
for creative lighting control, anding dramatic color effects
to the image, especially when more than one flash is used.
