Histogram won't show levels of marquee selected areas


Recommended Posts

Since updating to Affinity Photo 2, I can no longer get the histogram to show levels of a marquee selected area. Checking the Marquee box on top right now does nothing. I can get the histogram to respond to individual layers, but the marquee feature does nothing. 

 

In the attached photo, you can see the histogram pushed toward the highlights, despite having the eagle's wings (which are mostly black in the photo) selected. I left it overnight to make sure it wasn't a computer power issue, but I woke up to find it the same. HistogramMarqueeIssue01.thumb.jpg.e5f6ab7a73bb1040571589277f314328.jpg

This was previously reported against 1.8. I'm not sure if it was ever fixed.

Works fine here on Mac OS 11.7 so this may be a Windows only bug.

Mac Pro (Late 2013) Mac OS 12.7.6 
Affinity Designer 2.5.5 | Affinity Photo 2.5.5 | Affinity Publisher 2.5.5 | Beta versions as they appear.

I have never mastered color management, period, so I cannot help with that.

It seems to be working for me, on Windows 10, AP 2.0.3.1688. Are you running the most current release? Tested JPEG,PDF,TIFF and RAW (CR2 & KDC) images.

So I tried this on Affinity Photo 1, and it works perfectly. Unfortunately nothing I do on AF2 works (Change renderer - turn hardware acceleration off - etc.) Initially it seemed like such an insignificant feature, but I am becoming quite a bit annoyed at not being able to make this happen. I'm sure the answer is right around the corner...

I initially thought it was working for me, too. But then I noticed this sequence, which seems repeatable:

  1. Draw selection marquee
  2. Look at Histogram panel. "Marquee" is initially unchecked.
  3. Check Marquee setting, and histogram changes.
  4. Uncheck Marquee setting, and histogram remains the same as in step 3.

I'm not seeing that (#4). I can check/uncheck and the Histogram changes accordingly. I repeatedly check/uncheck, I'll get a slight lag in the Histogram (1 sec), but it does change.

Last night I left the marquee tool hovering over highlights. The next morning the histogram was correct, but as soon as I moved the marquee tool to the shadows the histogram freezes. Interestingly, if I create two layers, one black, one white and switch between them, the histogram responds immediately (not even a second delay). Of course this is not practical when I'm trying to darken an image just before the blacks clip. For now I'm creating a custom mask using a square set to erase. 

 

Thanks again for all your responses.
