That is understandable looking my screen HLCs in the image above, they exist over the editing HLC area and more this means there is HLC in my screen image even after the correction so -before and after- I lowered the saturation, I have colors beyond what by screen is capable to show and thats why I didn't see a change. When I lowered the saturation in my image to get rid of the editing HLC, I said I didn't noticed a change. I did this with mine, and the above image shows at the left side the HLC in sRGB and the ones in my screen profile at the right side. It will probably correspond to the best possible screen settings and viewing conditions which means this profile will show what is at least clipped in your screen and very probably a bit more is clipped in your particular case. However, having that profile is a lot better than nothing. Notice that this standard profile won't exactly portray your screen, because there are may factors affecting the way it shows an image, from its age and viewing conditions, to its current settings about brightness, contrast, white point and so on. The best next thing you can do about the screen HLCs is to google, download and install your screen standard. The best way to do this is profiling the screen and clicking or hovering the screen icon (Show monitor gamut warning) that appears at the top left corner of the histogram when we turn on the LR Soft Proofing feature. We should use that Soft Proofing feature more often, looking for image details that maybe we are not aware just because they are inside the ProPhoto space (not shown as clipping) but outside our screen capability (not visible in our screen). (Soft sRGB gamut Proofing) However, they are in sRGB (left image) space and (Soft screen Proofing) in my screen space (right image). There is none highlight clippings in LR the editing space. It uses the ProPhoto RGB space with the sRGB tonal curve (sometimes called Melissa color space). Nonetheless, in the case of LR we don't set the working color space. When none of the raw data channels is clipped, the shadow and highlight clipping occurs when the color from the camera raw space is outside the working color space used by the image editing software. In cases when there is blue HLC but the image dose not have the blue as the dominant color in the area, LR will show the HLC with a blue mask. That's the reason why -cleverly- LR shows the HLC with a red mask instead. Here we are loosing detail in the clipped blue channel but if LR would show that clipping with a blue mask, we wouldn't be able to distinguish the image blue area from that blue mask. But as we can see in this example, that is not (at least not always) the case. I have read in some articles that the red mask, showing the HLC, is indication of loosing detail in that red channel cyan indicating loosing detail in the blue and green ones and so on. As a consequence of that, the color for those pixels affected by the clipping will show a different color than they should or the detail in that area of the image is lost.Īrea with red highlight clipping, which is not reddish. When LR shows the highlight clipping (HLC), it is telling us that with the current parameters, one or more of the image (RGB) channels, for some pixels, require a value that should be higher than is possible and it is being clipped to the maximum allowed value.įor example, for some pixel values the green channel should be 107%, but as that is not possible it is actually clipped to just 100%.
