Want to add HDR-style detail-enhancing effects to your images? Ben Secret shows you how
In this tutorial I’ll go through three very common ways to make local colour and tone adjustments. Some of these adjustments are simply correcting things I’ve inadvertently made wrong. For example, this image of Louise Thompson, by photographer Ruth Rose, has been styled with a colour process that adds cold greens and blues to the shadows. This works with the backdrop and adds an interesting film-like colouring to the skin tones, but unfortunately the hair wasn’t so lucky, and has been turned a bit blue.
I’d also brought up the mid-tones, as it was quite a dark image, but this has had a bleaching effect on the jeans. So sometimes I’ll style things one way, then use local adjustments to fix all the problems I’ve created in doing so.
01 With a critical eye, one of the first things we should notice about this image is that the torso region seems a little cold and off-colour. So we’re going to select the Lasso tool, set the Feather to 15px, then roughly draw around the stomach region. Now add a Curves adjustment layer, and you should find it’s automatically masked the torso for you.
02 Now we need to figure out what we have to do to our curves to push the colour more towards the natural skin colour of the rest of the image. There’s a slight greyness to the mid-tones, so selecting the Red channel in Curves, just bring the mid-point up a small way to add some warmth. Do the same with the Blue channel, but bring it up slightly less.
03 These faded-looking jeans should be a little easier. As they’re red, we can use a Selective Color layer to localise the effect. The only problem is it will interfere with the skin too. So as before, use the Lasso to isolate the jeans, add a Selective Color adjustment layer, and with the Red channel selected, just bring the Black slider up a bit.
04 There are still some regions that could do with warming up – particularly that blue-ish hair. For this, we’re going to first create a nice, natural warmth effect for the whole image. Add a Curves adjustment layer and, as with step 02, bring the Red curve’s mid-point up a bit, and bring the Blue curve’s mid-point down slightly.
05 Now, ensuring we’ve got the Curves layer’s mask highlighted in the Layers panel, we should be able to flip this into a hide-all mask with Cmd/Ctrl+I. Next, select a medium-sized, soft white paint brush – I use a flow of about 20% – and we can simply start painting over anything we want to warm up, mainly the hair and shadows.
