Best Photoshop Effects: 21 Use Adaptive Wide Angle to correct distortion
Photoshop’s lens correction tools and automatic lens profiles already provide a way to correct wide angle lens distortion and converging vertical effects, but the Adaptive Wide Angle filter takes this a step further with manual correction tools that are quicker, more intuitive and more effective.
Our before image
You use the filter by adding and adjusting ‘constraints’ – the first icon on the Tools Panel at the top left. To fix barrel or pincushion distortion, drag a line out over the whole width of the picture to line up with a horizontal element, such as a horizon or roofline.
If Photoshop has a profile for the lens used, it will ‘bow’ the line automatically to correct the distortion. If not, you can drag the centre handle manually.
To correct converging verticals, choose a vertical feature on the left-hand side of the image, such as a wall or pillar, hold down Shift and drag out a vertical line along its length – this forces the object into a true vertical.
Now do the same with some vertical detail on the right-hand side – and that’s it. The filter will do the rest of the work for you automatically.
Best Photoshop Effects: 22 Straighten a horizon with the Ruler tool
If you’ve got a shot that’s not quite straight, or in the case of the picture on the right – way off parallel, then it’s easy to fix with the Ruler tool. You’ll find it on the same flyout menu as the Eyedropper tool.
Find a straight line in the image that should be horizontal, then draw a line with the Ruler tool from one end to the other. Now click the Straighten Layer button on the Options Bar.
If the image is a Background layer, Photoshop will convert it to a full layer. You can now crop the rotated image as required to straighten the ragged edges.
Best Photoshop Effects: 23 Tilt-shift blur effect
Photoshop CS6 has a new tool for creating tilt-shift blur effects, which you’ll find on the Filter>Blur menu.
You drag the centre of the blur gadget up and down to position the sharp zone in the image, then drag the inner and outer control bars to change the size of the sharp zone and the width of the transition to fully blurred.
You adjust the degree of blur by dragging the rotary controller around the central gadget. That’s not all – the adjustments can be made asymmetrical to suit more awkward subjects.
Best Photoshop Effects: 24 Lens profiles in Adobe Camera Raw
One of the major developments in Adobe Camera Raw has been its automated lens corrections, which are based on profiles calibrated specifically for different lenses. Not all lenses are supported, but Canon and Nikon owners in particular are well served.
Lens profiles aren’t enabled by default. You need to select the Lens Corrections tab and check the Enable Lens Profile Corrections box. Adobe Camera Raw will now correct lens errors automatically.
Best Photoshop Effects: 25 HDR toning to enhance shadow and highlight detail
Photoshop’s HDR tools are generally used to combine a series of separate exposures, but you can use the HDR Toning option (Image>Adjustments) to subtly enhance a single image, bringing out shadow and highlight detail without going for the full HDR look.
Our before image
Use the Local Adaptation method and the default settings, then try a large Radius and a medium Strength value, then set the sliders as necessary.
