I noticed brown banding on my LCD today in a froyo shop. When I took it outside, the brown banding disappeared. When I went back inside, it appeared again. I concluded it had to do something with the lighting. I changed the white balance as well and saw no improvement. After doing some googling, I've read about these bands appearing under fluorescent lighting only with certain shutter speeds. It has something to do with the cycle in the bulb. Apparently you have to shoot in 1/60th or slower at intervals/multiples of 1/60th to catch the light in the correct cycle. Has anyone else experienced these bands?
