Flat colors when merging to HDR

[renep54980445]

I just installed Camera RAW 15.1. For Real Estate photography I always using HDR of 3 shots 2 steps.

With al versions I had no problems, but with 15.1, the latest, the merged image has very flat colors.

I installed version 14.5 and that works normal. 

I'm starting to get tired of the problems after updates. I've been working with photoshop for 30 years but I'm kind of done with it.

15.1 is using PQ.

[renep54980445]

What do you mean by PQ?

[ZBalling]

Perceptual quantiser.

Do you have HDR set for your display? If so, disable; any difference?

Thanks Digital Dog, I'll check on that and try it. Colin

I tried all settings, HDR on HDR off. Color settings ect..

I always Merging 3 RAW files in  brdige by selceting them en merge in ACR. 

This works fine for me. But now the differnce is not acceptable. See this sample. Both photos are automatic colorerd in ACR.

Instead of Bridge you do so with Photoshop, any difference?

[renep54980445]

I also tried that, even the same result. The only way to keep the colors is top open them in ACR, merging them and using the DNG file.

If you disable GPU in preferences any different?

[renep54980445]

GPU preferences disable/enable, no difference.

Recalibrate and build a new ICC display profile; the old one might be corrupted. If you are using software/hardware for this task, be sure the software is set to build a matrix, not LUT profile, Version 2, not Version 4 profile.
 Any difference?

Thanks, I did, i'm working with an EIZO and calibrate is every month. But also the same result, flat colors.

I'm using ORF Olympus raw files, but also with DNG or JPG, merging HDR in Bridge gives me poor colors.

The only way is to open the files in ACR, then merge them to DNG.

Can you get the same result in the 15.1 version by simply doing the sliders manually (should take two seconds or so)? It appears this might simply be a problem with the auto-settings AI in the newer version not being aggressive enough for you with shadows and highlights. I doubt the actual data in the HDR merged image is any different.

[renep54980445]

I tried that, but it looks that the dynamic range is very low, can't get the same resullts.

Can you share some originals and merged DNGs? I just tried with images I had merged before and the result are identical to the merge done in older versions. The results of "auto" seem to be different although I can't tell as a basically never use the results of "auto" as is but using the same settings as on the older merge gives identical results.  It's possible the AI-driven auto algorithm was changed. the merge results seem to be identical though.
