Problem since I bought app one year ago;
I have a wide gamut monitor (Benq SW2700PT) and a couple regular sRGB monitors, all monitors are calibrated.
If I drag the D.Opus photo viewer over to wide gamut monitor, images oversaturate and get very contrasty. If I move old old Windows Photo Viewer from monitor to monitor, images looks the same.
Could it be that D. Opus is not calculating difference from sRGB image to wide gamut monitor? I've tried everything, but only thing helping is forcing my $700 monitor to render only sRGB primaries.
I see the same problem with thumbnails in D. Opus.
Color correction is quite basic in the viewer at the moment.
You can configure the color profile (if any) the image viewer uses, but there's only one profile option, so if two different monitors have different profiles it's going to look wrong on one or the other.
In my case I'm mainly using DOpus on the one photo monitor I got, and the colors get oversaturated and contrasty even if I select the calibrated ICC for my photo monitor. I think the "monitor preview" output of DOpus to GPU is sRGB or assume monitor is sRGB, and that preview data get "stretched to fit" inside my monitor which is hardware 16bit LUT AdobeRGB causing the oversaturation and contrasty look. Could I be right? I'm not a programmer.
I have a suggestion for future developement - if I may add. Look how Skylum, XnViewer MP (Free), Adobe software and other graphics software work. It grabs the ICC from the current monitor it is showing up on, and it happens regardless if the programs have multiple instances open, and it calculates proper values for monitor despite it is hardware calibrated wide gamut.
Yes I know that, I just wonder if the preview ending up on monitor via GPU assumes monitor is "sRGB gamut like" and therefore sending off a compressed datastream to the monitor. Like when sRGB preview reach monitor it gets stretched to "full output" of AdobeRGB since monitor is calibrated for AdobeRGB primaries. Just speculation.
I don't know, I just know that on my sRGB gamut monitors the preview is 100% identical with photoshop. If I move window over to photomonitor it gets oversaturated and contrasty even if I select that monitors ICC.
I have a monitor with a hardware set color profile. From the profile creation software I have made an ICC profile from the hardware settings.
I have applied that profile to the Opus picture viewer and to Adobe Photoshop CC. The same picture viewed in each application looks identical, and, as the monitor is hardware calibrated, the thumbs match, too.
Not sure what your problem could be, I am afraid, but it works a treat here.
You are not supposed to apply your monitor profile in Photoshop to anything, it assumes the current one on actual monitor is in use by WCS (Windows Colormanaged System). Same reason why you're not setting any "monitor color profiles" inside of Lightroom. The color profile options in Photoshop is for "file output" and not monitor preview - unless you do a proofin, but thats another topic.
We are talking about device profiles, not file export profiles.
If it works great, would you be kind to show a screendump from DOpus side by side with Photoshop? Thanks
You need an ICC profile (i.e. .ICC or .ICM file usually), and you need to tell Opus to use it. It won't pick up the profile from Windows automatically.
Sounds like that hasn't been done?
It's set via Preferences / Miscellaneous / Advanced [Image Formats]: use_color_management which is off by default.
This is very strange. I hardware calibrate my monitor and the image I see in Photoshop are great while the image in DOpus are extremely oversaturated and contrasty.
Could you please show with screenshots where you place your monitor profile and do the gamma correction?
I never experienced images in both apps like you show above. Ever.
Colour is such a subjective business, it is difficult to comment on your example.
If I were you I would start from scratch, by taking a reference image with a digital camera and use that image in all your setups. The Kodak reference ( widely available on the Web) is what I used.
I enclose the Mystic Coder set-up simply for completeness. I thumbnail with this program as it is the only really reliable thumbnailer I have found that will give me transparent backgrounds to eps and pdf files. So this probably will not apply to you.
Thanks for the screenshot, I'll review all the settings later. Yes I use Gregory McBeth charts/colorchecker
Just a small note, your first screenshot where you put monitor color ICM. Why did you put your device profile here, I've learned from Xrite and colorgrups on internet that you should never use device profile as working space, that this is where you put file colorspace like sRGB and AdobeRGB. If I put mine screen profile there I will get a big difference from Lightroom to Photoshop.

Interesting article, and contrary to what I was taught - not that that is necessarily right, of course, especially as it was many years ago in the infancy of Photoshop - version 2 on a Mac to be precise.
I have decided to follow the advice of the article and move to sRGB as a colour space.
The only extra work I had to do was to play with the gamma on the Opus picture viewer.
This is t he result with the sRGB colour space on my system.
