Curves + Luminosity = Better Tones
In the last blog entry I mentioned some cool things you can find in the Curves dialog that help you adjust the tonal range of your image. Today I’m going to show you how to wreck the color in an image in the name of improving tonal range.
The Curves dialog has four channel options – you can work on the RGB composite channel (the default), or you can work on the separate R, G or B channels. Problem is that although adjusting the R, G or B channels independently can help you improve the tonal range of the image – it can also totally mess with the color. For this reason, few users bother working with the individual channels. Makes good sense? No!
You see working with individual channels is a good fix. If the Red or Green channel lack contrast you can hype it up using a curves adjustment. You’ll mess up the color but, if you’re using an Adjustment Layer, you can simply change the blend mode of the adjustment layer to Luminosity and immediately the messed up color disappears and the adjustment is limited to luminosity only. Instant fix.
So, next time you need to apply a Curves adjustment, check the channels in the Channels palette. If you see a channel that lacks contrast – adjust it to add contrast to it. Then set the blend mode of the adjustment layer to Luminosity to remove the color problems you just created.
Sharpening is the last step in editing an image. If you’re working in Lightroom then you have a very sophisticated Sharpening tool at your disposal. It’s hard to determine what the coolest part of the process is – the Detail and Masking sliders or the […]
The Curve dialog in Photoshop hides some surprise features that aren’t immediately apparent at first glance. In Photoshop CS3 and later, one surprise is that you now have the adjusters under the chart that you’re used to using in the Levels dialog inside Curves. So […]

I’m in a mild state of shock today. I’ve recently read Watching the English by Kate Fox and discovered things about myself that I was better off not knowing. If you’ve not read the book it can be neatly summarised by the following: in terms […]
