OK. I been bragging about my billy record but it's got a small problem. When i try to use f16 or f22 i get a blue or purple color shift. I'm using fuji reala 100asa.
At f8 or f11 it works great but smaller appetures cause this color shift. The exposure seems ok, not too light or dark but the color is off.
Any ideas? or should I just consider those settings off-limits?
