QUICK TIP Double-click to apply a profile and close the Profiles panel in one go If you want to make your own Profiles, it’s really easy. To create new Profiles, you simply make a set of edits in Camera Raw then save it as a new Profile. (You can also include Color Lookup Tables created in Photoshop.) Profiles can only be created in Camera Raw, not in Lightroom. But the great thing is that once you’ve made the new Profile, it’ll appear automatically in Lightroom the next time you restart the program. 01 MAKE YOUR EDITS You can create your own Profiles in Camera Raw with ease. Begin by choosing an existing Profile, then go on to make any changes you like using the usual tonal sliders, Curves or anything…

01 WHAT IS THE DISPLACE FILTER?? Found under Filter > Distort, Displace lets you skew the shape of one image to conform to the surface of another, so it’s useful for blending two images in a believable way. It’s unique in that it requires you to load in a displacement map (see right) to suggest texture. 02 HORIZONTAL AND VERTICAL VALUES It’s usually best to keep the Horizontal Scale and Vertical Scale values the same in the Displace dialog box, but sometimes it might make sense to increase one or the other to create more of a shift on either axis. Here there’s little need for horizontal displacement. 03 SMART OBJECTS Settling on the right Vertical and Horizontal values may take trial and error, so before you apply the Displace…

There are plenty of techniques for sharpening your photos, but few are as effective as High Pass sharpening. This method makes use of Photoshop’s High Pass Filter, which separates an image into high-frequency and low-frequency detail. It allows you to target the edges in an image – where light pixels meet darker pixels – and apply contrast to them, resulting in crisper details. The High Pass technique is especially suitable for localized sharpening of specific areas in an image. If you think about it, when an image has out-of-focus, detail-less areas (as is often the case with macro photos, for example) there’s really no need to apply universal sharpening: all you end up doing is amplifying the image noise in detail-less areas – not ideal at all. For images like…

The new Profiles in Camera Raw and Lightroom are a great addition to your workflow – either as a starting point for further editing or as a shortcut to get different looks and effects. But what do they actually do to your image? Profiles are Lightroom and Camera Raw’s interpretation of an image’s raw data. HOW TO APPLY A PROFILE You’ll find the new Profiles controls at the top of the Basic panel, both in Camera Raw and within Lightroom’s Develop module. Expand the Profile Browser menu by clicking the square grid icon and you’ll see an array of one-click treatments. Hover over any for a preview of the effect on your image. Click to apply it, or double-click to apply it and close the Profile browser in one go.…

One of the most exciting things about the new Profiles feature in Camera Raw and Lightroom is the fact they work with Color Lookup Tables, or LUTs for short. If you’re unfamiliar with LUTs, they’re simply a way to remap one color or tone to another. As an extreme example, if something is a shade of red, you can create an LUT to set that shade of red to be green instead, or whatever color you like. For this reason LUTs are often used for color-grading videos, as they offer a rigid form of toning that creates a uniform effect across the footage. All kinds of tonal adjustments made in Photoshop can be exported as LUTs. You simply use Adjustment Layers to change the image, then export the Color Lookup…

The Displace filter shifts pixels up or down and left or right based on the brightness of the displacement map, in order to approximate a 3D surface. The horizontal and vertical values (H and V) [1] can go to +/-999, although you rarely need to go above 50. The diagram above shows how this pixel-shifting works. The centre circle [2] is unchanged. In the top left [3], both H and V are set to a positive value. Areas of the shape that sit over the brighter parts of the displacement map are pushed upwards and to the left, while dark areas shift down and to the right. Set both to negative values [4] and the brighter areas shift down and to the right. If you set H positive, V negative…

01 MAKE A MAP Open the tree.jpg start file, then go to File > Duplicate to make a copy. Go to the copy, press Cmd/Ctrl+Shift+U to desaturate, then go to Filter > Blur > Gaussian Blur. Set amount to 9. Next, press Cmd/Ctrl+S to save the file. Name the file ‘map’ and choose Photoshop Document in the format settings, then click Save. 02 DISPLACE THE FACE Go to the color tree image. Go to File > Place Embedded and load in face.jpg. Press Cmd/Ctrl+T to use Transform mode to position it, then go to Filter > Distort > Displace. Set the Horizontal and Vertical values to 15 and click OK. Set the Blending Mode to Darken, then add a Layer Mask and paint with black to hide the edges of…

Photoshop has many types of layers and adjustment layers available, but there are six that you’ll find you need to use again and again. Learning how they should be used may seem a little daunting for beginners, but once you’ve got to grips with them, you’ll find they play a part in the creative process of almost every image you make. 01 LEVELS This should be the first layer you add to an image, because it fundamentally alters the tonal range of the entire image. Create a Levels Adjustment Layer, drag the Black Point slider inwards until it touches the left-hand edge of the histogram, and drag the White Point slider inwards to the right-hand edge. This remaps the tones of the image to make more of the available tonal…
