I’ve been trying to profile my camera using darktable-chart and a Datacolor Spyderchekr. Unfortunately, the .cht file for this color checker that comes with Argyll has some issues which make the file unreadable to darktable-chart.
In particular, I’ve found that the newlines in the file were not inserted correctly, which made the file unreadable. I’ve fixed this and now the file can be opened (I’ve googled this and found a few other users having the same issue).
Nonetheless, another issue remains: darktable-chart cannot read from this .cht the Lab (reference) values:
As you can see from the screenshot, the fourth column is empty. I’ve tried other .cht files, and they all read correctly. It’s just this one that doesn’t.
I’ve tried going through it and tackling the issue, but I’ve had no luck.
Here is a copy of the .cht file: BOXES 49 F _ _ 62 49 1684 49 1684 1187 62 1187 D ALL ALL _ _ 1684 1187 0 0 - Pastebin.com
Does anyone know what could be wrong with it?
Thank you in advance for your assistance.
