Andrew, Ben
I have been using the i1 Pro revision "D" and also have the i1 Pro revision "A". i1 Publish with the dongle. I profile my Epson Pro 9900 44 inch wide printer using the i1 Publish and the i1 Pro revision "D". Targets are printed from i1Publish. Targets dry for 48 hours.
I use the NEC PA 271w display, profiled daily. I meticulous in my procedures.
Computers are a pair of MacBook Pro 8,3's, non-glare displays. I profile clients' displays, as well as clients' printer/ink/substrate. 16 GB RAM in both laptops.
Creating the sensor/lens/lighting custom .icc profile has been with exposure with gray card or white card. Currently I am using the gray part of the CCpassport. Once exposure is
locked in. I photograph the CCpassport 24 patch grid. Convert the RAW file with Adobe DNG converter then use the Adobe DNG profile editor. I won't even discuss the X-Rite software.
What has got me extremely interested is the potential for an even better by the numbers camera/lens/lighting custom .icc profile with RPP. For all I know, I am
on the wrong track. Maybe RPP cannot do this.
This meticulous procedure is required for reproduction of artists' original art. I cannot glorify or manipulate the image file created for them.
Lighting is with Paul C Buff Ultra 1800's, polarizing filters on them, and on the lens of the camera. On the camera lens is also a UV / IR filter.
So………am I wasting time, energy, money with this RPP?

This will require a chart with many more than just 24 or 50 patches. There are commercial targets available, but you can do better -- much better -- by making your own. You'll need a spectrophotometer, presumably the i1 Pro, but you're going to need that regardless.

You'll then develop the images you take of the art using those same white balance and exposure settings, with RPP tagging it with the pre-canned profile you took earlier.
