Thanks. You are right, further studying showed that WPV is color managed but Windows Photo is not. However, WPV is managed not with the profile the monitor calibrated with thus the over saturation. I found a good picture managing app that can load the same calibration profile ones calibrated, its called fastpictureviewer and the free version works great Good luck to you too! ... View more

Amazing community and thanks to Roei who created this thread to help figure this out together along with so many talents. To thedigitaldog: Watched through your two-part youtube series about color management and it is EXTREMELY helpful. Very technical and informative. I need to take my word back on "The concept seems straight-forward..." because there are so much complexity in it I really thinks I still knows nothing about. To D Fosse and all: Read through all your discussions and I believe I have reached some sort of methods that I am going to approach with. 1. Treat my Dell U2410 as a specialized tool, calibrate and profile as WG should to maximize the usable color space 2. Change back the "advanced" system default profile (thanks D Fosse), and make my device default to my calibrated profile 3. Ignore Windows Photo Viewer and Windows Photo or other crappy not-color-managed apps altogether. Focus solely on LR and PS on my edits. 4. Export to Adobe RGB 1998 if I want to print physical, export to sRGB for digital usage 5. View these exported photos on a separate PC/Monitor that mimics typical unmanaged client's PC's environment. ----- Bottom-line: with the above method, I will know the work I am working on, under my particular environment only, is as true to its color as possible. Then understand there is no way to control what clients' will see on their screen, but knows that it won't be too far off since it will all be relative to how their system behaves. Hope this method can keep me sane for the last time. On the other hand, still don't understand why Windows Photo Viewer's color is different from the Windows Photo? If both apps are not color managed, what gives them to behave differently in a same system? ... View more

Thanks Roei and thedigitaldog for the quick response. The concept is straight-forward indeed, but in actual practice it isn't so clear within Windows as it doesn't clearly tells you which apps are color-managed or not color-managed (or managed to what profile exactly). I definitely feels Roei's pain as we cannot control clients setup and apps used when viewing our photos digitally. Since there is no guarantee on the colors others see in their computer, my goal is to get it as accurate as possible (not extremely saturated). Which brings to my observations below. After playing with the profiles and Windows Photo Viewer (denoted as WPV), Windows "Photos" (denoted as WP) a bit more, I have observed the following with the colors: Standard color profile:         LR == WPV (both less saturated), WP slightly saturated My calibrated color profile:  LR == WP (both slightly saturated), WPV extremely saturated The above observation doesn't make much sense, but it can definitely be my lack of knowledge. If there is a way to know what app uses what color profile, and if someone can help explain the above observation, I am all ear. Lastly, I'm gonna enjoy the 2-part video thedigitaldog recorded. ...

Now an even weirder situation just happened as I reconfigure my color calibration (using Colormunki Display) and reset my device profile default to the newly calibrated profile (Dell_U2410_D65_20170505_sRGB). For some unknown reason Windows Photo Viewer shows extremely dark and saturated. "Photos" is slightly saturated, and LR seems normal... if I know what normal is now. Did I do anything wrong? ...

I know this topic hasn't been updated for quite some time now, but I would like to continue asking more questions and share my experiences. Since I've learned that editing in WG only benefits printing or people with WG monitor and viewed with color-managed apps... I resort my monitor preset, calibration and editing (PS and Lightroom) within the sRGB space. However, I have noticed even in the sRGB space, the image viewed from Windows 10 "Photos" are off against the Windows Photo Viewer. From my research, Windows Photo Viewer is color-managed but "Photos" is not, this confuses me. Since Windows Photo Viewer's full-screen-slideshow-mode switches to "Photos" app automatically.... if I need to give works to my client, they will see two different colors and don't know which is correct. Below is a screenshot of an example image. Windows Photo Viewer's color matches that of my Lightroom, but "Photos" app is much more saturated. My monitor is Dell Ultrasharp u2410, sRGB mode. This confuses me as to what should I edit to as my baseline... as I don't want my clients to think I oversaturate everything lol. ... View more
