Hi Experts, what am I doing wrong.? or maybe not me, but what gives in this case ? This a photo shoot Florida Beach at Sunrise. I am baffled. This roll of film is Fuji 400H , (a fresh roll) and kept in fridge before exposing. Frozen for two weeks after exposing and before processing. If this was a processing problem on my side, I am sure all images would have had a similar problem. right ? But the different color casts in consecutive frames is baffling to me. See attached scanned film frames. IMG027 has the correct skin tones. the next frame IMG028 has a cyan cast, and finally IMG030 two frames down in the same strip has a magenta cast. same roll of film. is it possible for that to happen or something wrong with my scanning process ? Shooting Conditions: Note that the shots are very similar close ups of the girl and the lighting condition should have been the same on her for the three shots. I used a Canon Speedlight 550EX in a small softbox with silver interior , and a silver handheld reflector on the opposite side to fill in the right side of the girl. The shots are only a few seconds apart from each other. Scanning process: the strip of film was scanned without applying any corrections so the casts are exactly as they show. Most of the other frames have a cyan cast. I dont know how to verify with naked eye if these color casts exist on film by just looking. the heavy orange base of the negative film is not something I am used to analyze, but I can try with some tips if provided. Note: I know it would be easy for me to correct in several ways, with scanner adjustments, or even in the printing process, but I am extremely curious to understand if this is actually possible to happen and what causes it. so to avoid in the future. thank you again.
