Herbill Posted January 28, 2021 Share Posted January 28, 2021 I know how to handle blown highlights and crushed blacks, but how should I handle crushed colours i.e. where the peak on the histogram goes outside the frame.

Suggestions welcomed. If by peak you mean the height of the histogram, I just ignore it, all that means is there are a lot of pixels with that level of 'colour' Quote Mac Pro (Late 2013) Mac OS 12.7.4 Affinity Designer 2.4.1 | Affinity Photo 2.4.1 | Affinity Publisher 2.4.1 | Beta versions as they appear.

Herbill Posted January 28, 2021 Author Share Posted January 28, 2021 That's exactly what I mean Bruce. Like you, I have ignored these peaks in the past. Are you sure that the peak refers just to the number of pixels and not crushed colours? Quote Link to comment Share on other sites More sharing options...

The relative number of pixels. Do a test with some mid range colours to see for yourself. Make some documents (small size, say 100 pixels square) and fill different portions with different colours, the more area you fill with a mid range colour the higher that will be. Move your cursor over the histogram and watch the readout change as to the number of pixels.

Herbill Posted February 1, 2021 Author Share Posted February 1, 2021 You are right, the peak refers to pixels and not crushed colours. I believe that managing the histogram in Raw will solve so-called crushed colours. Thanks for your assistance. Quote Link to comment Share on other sites More sharing options...
