I am finally going to take this seriously, but need some instruction.
my process:
1. with a diffuser over the lens, take a shot in the same sort of lighting as the image to be corrected. Adjust exposure to center the histogram (maybe a stop or two more, done with the shutter speed)
2. repeat this for various amounts of shift, cataloging the images.
3. here is the part i am unsure of: when the LCC shots come into Phocus, do I apply any corrections to them, such as white balance or exposure, before applying them as a scene calibration? Typically, my H39 back produces as shot images that are way our of white balance into the magenta, even though the back is set to daylight.
my thinking is that Phocus looks at the LCC file, figures out what and where corrections need to be made to get it all neutral, then applies those corrections, whether the entire image is way magenta or not, it will correct local cast and overall WB in one go
thx
