Thanks. They've always maintained that ticketing protocol, but also made their phone number available. Apparently their 3rd party email sever was down for 2 days, but they weren't communicating that with their clients. Disappointing.

I've been pleased for over 10 ten years, but suddenly there's no email, and almost no support response. They've removed their phone number, bad sign, right? Anyone else using them or have any news?

You are both right, and I suppose good to know that even at my age I have plenty to learn. Thanks very much, and wherever you are, enjoy what’s left of Mardi Gras.

Yes, that's what I did. Thanks

Welcome to my life. They're getting 3 versions with different levels of fluorescence. They cleaned up pretty well, though my hourly fee works out to 5 cents. Thanks, Rodeo Joe!

Yes, I know, I put them there out of habit. I use a Color Checker passport, but it's too small for these giant paintings. I made 3 different lighting profiles for my different setups (moved the camera), and was really surprised that they had very little effect when I was processing. I've learned I need to pay more attention to exposure...

Sadly, that is impossible. I have some hotter exposures that I'll look at. Getting that article and learning about RawDigger was [almost] worth it. Thanks again.

This article is very helpful, thanks. Though I'm not sure I could have opened up much without blasting out the fluorescent portion.

I am afraid I know little about sensitometry...the channel histograms are for the white patch? Is the red channel significantly shifted because my umbrellas skew red? I underexposed to maintain detail in the center fluorescing area. I think I would try to light it differently next time. So this is probably the source of my issue? You say "first major issue"....do you see another??

Thanks, John. The painting is a trapezoid! And the band in the center (vertical stripe) is caused by a difference in the fluorescing material. I've never looked at a hue map; is this specifically for viewing color shifts? This was really hard to make it appear like it does to your eyes. That's why I chose to light it for the center and underexpose the rest. I guess the weird color is from grossly underexposing the rest of the scene in order to capture the fluorescent center. So glad I don't do this on film anymore...

Thank you so much for taking the time to look at this. The area in the center is coated with a fluorescent material that only reacts with a pretty direct light, so I planned to adjust the flat white side panels digitally. Thanks for the reassurance. I will get my screens recalibrated and keep going. I appreciate your help.

Sorry, wasn't thinking. Here it is: Dropbox - PG_19__DSC3052.dng Please don't share this image off this forum. Thanks.

Hi. Sorry, I can't figure out how to post the dng file...I can't really put it on my website....

Thanks. This makes me feel a bit less worried. Though there may be a lighting issue, since there are some magenta streaks around where my umbrellas were hottest. Re: your afterthought, I think exposure is involved but it’s confusing. The most affected areas are pure white with almost no texture, but they’ve been underexposed in camera by about 2 stops, because other areas are a very reflective material that I didn’t want to blast completely out. Fun. I will post a better image on Monday. Thank you so much!

It does look a little like posterization ... I am away from my computer for the weekend, will check the ratios on Monday. Should I check the mauve areas vs the green? I do not know as much about color management as I should. I have looked on my other monitor, that was one of my first thoughts. The odd magenta and greenish areas are still there. What I posted was a screenshot png, from a 300 percent enlargement of the dng in camera raw. It’s like the base is green, and any image detail is that mauve color. When I re-did the white balance after my original post, it got better but still there. Thanks so much.
