WB Flash + Fluorescent JPG

[titoSantana]

Hi, I have a nikon D7100 and a SB-910. I was shooting without my flash under Fluorescent, the Wb was good under Fluorescent setting until I used my flash.
Thanks

You are mixing two differnt color temperature sources. You will need to correct one of them to match the other.

The easiest way is to put a gel filter in front on the flash to make it the same temperature as your fluorescent lighting. You'll need to find out what they are (cool white, warm white, daylight etc). Then buy a filter to match and set the camera's WB to the fluorescent lights color temperature.

Some flash units come with a gel to use for a couple light sources other than the normal daylight color of the flash unit. Your SB-910 should have come with the Incandescent (amber color) and Florescent (green color) filters in the box.
