Billtils - I wasn't aware of luminosity masking until you mentined it. I'll check it out and see if I can figure out how to apply it with one of my images. I'm somewhat conversant with PS so if I do get it to work, I'll give you some feedback with, hopefully, before and after comparison shots. Also, if you have any suggestions for luminosity masking tutorials, I'd appreciate suggestions.I've been exploring luminosity masking lately, and would be interested to hear from members who use it, especially your experiences in regard to where it fits into your workflow.
Thanks Dan. A lot of what I've read seems to suggest that the ability to mask according to the luminosity in the original image is what distinguishes the technique from creating a mask by brushing or lassoing. I'm not familiar with ON1 but highlights/midtones/shadows adjustments are simple in Capture One so perhaps the effectiveness varies according to the editor in use.I use it in ON1. Not sure if it works the same in PS but in ON1 there is a slider with adjustments for highlights/shadows/midtones. With some tweaking it can be pretty useful. Obviously the more contrast in the image the more effective the luminosity mask is. Really comes into it's own for creating HDR effect from a single frame. I never used it until ON1 in their infinite wisdom broke the auto mask feature and never replaced it with anything nearly as useful. But now out of necessity I'm learning to use it as about an 80% solution for the old automask then completing manually as necessary.
Thanks Karen. I read an enjoyed the material on the Kuyper link.Luminosity masks are a great way to isolate particular areas of an image in order to apply curves and other adjustments. I have used Tony Kuyper software for years. His s/w includes an extensive user panel to enable easy creation of the masks and then application of various adjustments.
Luminosity masks enable you to create a mask based on tonal range. Imagine you have an over exposed sky that includes trees in the horizon. It would be impossible to mask between the tree branches with a brush. With luminosity masking, you can tell the s/w to select areas of the image based on a specific tonal range. If you select a very light tonal range and the branches are darker in tone, you automatically get a mask selecting only the bright sky areas – even around all the intricate little branches. You can also use it to select dark areas for shadow recovery, select mid tones for clarity, etc.Thanks Karen. I read an enjoyed the material on the Kuyper link.
I'm still a bit unsure exactly where luminosity masks offer something over conventional masking using a brush or lasso, although Dan does touch on that in post #3. I'll keep experimenting ...
Walter, I liked your illustration but not sure about the "impossible" - you can do that selection in Affinity Photo, and also use its layer blending to achieve the same result. However, it does seem that the various LM plugins offer a simpler way to get to the same result....It would be impossible to mask between the tree branches with a brush.
Great! Feel free to ask me questions about it. The new radial mask will also be a welcome addition for you. Far more flexible than the simpler vignette tool. The updated asymmetric gradient tool is just more icing on the cake.OK Walter - you did it! I was one of the Capture One 11 to 12 upgrade cost objectors but have now done it and (subject to more hands on experience) am happy.
