Hello and thanks for all the interesting responses!
I think this thread is going a bit off topic...
Going back to the original DIY charts...
I see the main point that many of you raised is that, simply printing a chart wouldn't be enough for an accurate profile and I see the reasons for it.
After a bit of thinking I came up with this idea (that obviously is not entirely mine): why not to use more, completely different, charts to create just one profile?
Argyll enables you to read various chart and combine all the data in a profile, therefore why not to use (just to make an example but please let me know your suggestions):
- Chart 1: IT8
- Chart 2: ColorChecker
- Chart 3: DIY Printed Chart (up to you what colors to use here but I would use the "cardinal point" of the LAB and then make gradation)
- Chart 4: DIY Acrylic Color Chart (what do you suggest to use as color?)
- Chart 5: DIY Filter Color Chart (create a frame with many pieces of various filter, ex Lee Filter Swatch Book, and then retroilluminate everything)
- Chart 6: A detailed greyscale + light trap + super bright reflective material for white.
I know it might be a super long process but I think in this way you could cover many more colors than a normal commercial chart...
Looking forward to hear your suggestion!
Thanks a lot!
Ale
