Photoshop Tutorial : Quick Colour Correction Techniques

So lets look at a couple more techniques you can use for colour correction (fixing colour casts etc.,) in Photoshop. You can probably use both of these methods in any image editing software btw.

Neither of these techniques will work on all images, but because they are so quick to do, they are usally worth taking the 20 seconds to try them out.

The start image is brought to us by Orbán Ferenc over at the Stock Exchange site.

Open the image in Photoshop and then grab the rectangular marquee tool. You are going to make a selection that includes a lot of different tones in the image. Reference the image below to see where I made my selection.

Open a levels adjustment layer by clicking on the little ying yang symbol at the bottom of the layers palette and choosing levels. Where the dialogue box opens, go to options at the right hand side of the dialogue box and make sure enhance per channel contrast is selected.

Click OK to accept that and then press Auto – and you should end up with something similar to the image below.

So that looks a little strange 🙂 Hold down the shift key on the keyboard and click on the mask – and there you have a quick colour correction.

On to the next quick colour correction

Open the image again and add a new blank layer above the b/ground layer by clicking on the ‘create new layer’ icon at the bottom of the layers palette. Grab the eyedropper tool by pressing i on the keyboard or using the side toolbar. You can reference the image below as to where I selected the colour from in the image, or, the RGB colours are 142 – 127 – 93.

Fill the blank layer with that colour. Press Ctrl + i on the keyboard to invert the colour and then change the blend mode of the layer to overlay and you can take the opacity of the layer down if you like – I adjusted mine to 75%. If the colours appear a little washed out, you could also add a hue/sat adjustment layer and boost the colours a little. You could also try a soft light or colour blend mode. If you use a colour blend mode you might have to take the opacity of the layer down to about 20% (or to your taste) On the image below I used a hue/sat adjustment layer to boost the master by 15%, then I added a levels adjustment layer and brought the sliders in on RGB channels.
