I’ve been processing my most recent film scan - Kodak Portra 400 this time. A lot of the scans turned out nicely with very little messing around - sample the film base and adjust Dmax (mine is set quite far from the default - between 0.9 and 1.0 for most of this film… is this normal?)
A couple of shots were taken on an overcast day and the resulting scans look very blue… so I tried the colour calibration module to alter the illuminant. This seemed to work ‘backwards’ - raising the Kelvin value made the whole picture more blue. After some thought I figured that it was operating on the image before negadoctor. Altering the module order made it work in a more intuitive way. I’d think it would be more correct to operate on the positive image rather than the various shades of orange in the negative too.
After doing this I found that doing the same with Exposure and Graduated Density made them work in a more intuitive way too.
Are there any downsides to doing this?
If what I’m doing is correct then why does the default order place negadoctor after these modules?
