Okay round 2, modified formula different film.
Only change is the addition of 280mg/L of Sodium Thiocyanate (still think mine needs to be dried out a bit) to Bath A (Bath A and B were kept from previous go).
This time with fresh Kodak Gold 100 from B&H. One half was cut and run through a frontier C-41 to get as close to 'everyday C-41' as possible, other was the split bath (3m 15s A + 6ms B). 24 Colour Patch was shot on both at box speeds.
ColourChecker shots balanced with the 4th grey patch (4th darkest), and contrast matched as close as possible so any difference in the colour patches between the two will give more information on the colour.
Also going to use the Xrite software to create a profile for the C-41 and split-bath shots using the colour chart, so I can preview the difference between uncorrected and corrected colour, and see which colour patches shift the most (the 'most incorrect').
Scanning now, will edit and start including images after lunch break, I need to do a round about way of this.
Here are some initial results (will get some actual images to look at up later)
(I'm going to need to shoot a chart much closer up and redo this i think)
C-41 Gold @ 100
Split-Bath #2 Gold @ 100
Split-Bath #2 Gold @ 400
