Best Photoshop Effects: 31 Colour grade an image with multiple layers
If you cut out a portrait, for example, and place it against a new background, the colours may clash because of variations in the lighting or white balance.
So duplicate the Background layer, bring the duplicate to the top of the Layer Stack and use the Average filter (Filter>Blur menu). This creates a single, averaged colour for the background.
Now set the Blend Mode to Overlay and adjust the Opacity of the layer to harmonise the colours in the two layers.
Best Photoshop Effects: 32 Set black and white points in Adobe Camera Raw
The histogram in Adobe Camera Raw can tell you whether shadow or highlight areas are clipped, but not whether they’re in an important part of the image.
If you hold down Alt as you adjust the sliders in the Exposure tab, the display changes to show the clipped areas against a white or black background.
You can use this to decide which areas of the image you can afford to clip, which enables you to get the best overall contrast range in the rest of the picture.
Best Photoshop Effects: 33 Remove chromatic aberration
All zoom lenses produce some degree of chromatic aberration, and many prime lenses, too. Adobe Camera Raw has a new method for removing it that’s no longer tied to specific lens profiles.
Go to the Lens Corrections section, select the Color tab and then check the Remove Chromatic Aberration box. This should fix the fringing with a single click, but if not, you can modify the adjustment using the Defringe sliders directly below. It’s both faster and more effective than the old system.
Best Photoshop Effects: 34 Hand-tint with brushes
Hand-tinting is a technique usually associated with retro-style black and white photos, but it can be very effective Adobe Camera Rawoss a much broader range of genres and subjects.
The key to getting the effect right is to choose the right colours in the right strengths. The colours gain strength and depth from the black and white tones they overlay, so you’ll find you need to start with paler and weaker colours than you’d expect.
The secret to the technique is to create a new blank layer over the original black and white image and set the Blend Mode to Color.
When you paint on this layer, it’s like painting on a sheet of transparent acetate – the colours are overlaid on top of the black and white image below.
If you paint on a single layer, though, it’s difficult to reverse mistakes and modify the effects later. Instead, create a new layer for each colour you want to apply.
If you reduce the layer Opacity before you start (to 60 per cent, say), this gives you more leeway if you need to adjust the strength later.
Now use a large, soft brush, select your colour and paint carefully over the image. You don’t have to be too precise, because the shading and outlines of the objects in the picture effectively disguise any overspill.
