Contrast is usually at its highest when a scene is backlit. In this image there wasn’t much that could be done to lighten the shadows. I exposed so that the highlights weren’t too badly burnt out and didn’t worry too much about the shadows. Contrast […]
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 […]

Next time you’re in the countryside at night do yourself a favour: look up. If it’s clear and conditions are right you’ll see a seemingly infinite number of stars twinkling like diamonds on a sheet of black velvet. As a visual pleasure it’s hard to […]
Colour can be distracting. Stripped of colour an image is entirely about the subject (unless of course the entire point of the subject is its colour…). This is particularly true of portraiture. Black and white arguably conveys the inner soul of the subject more powerfully […]
