Motion blur: how to use layers, filters and masks to create a sense of speed
Jun 15th 2014, 23:01, by jmeyer

Motion blur, which makes a subject look like it's moving quickly, has become a familiar effect in photos and movies – even though it doesn't exist in real life.

Motion blur: how to use layers, filters and masks to create a sense of speed

Motion blur appears when a camera exposure is long enough for the subject to move across the picture frame, meaning the light coming from the subject hits the lens several times – causing the tell-tale blur effect to show in your picture.

Motion blur may not be real, but it's a useful way of suggesting speed or movement in your images. You can choose to set your shutter speed to create motion blur when you take your shot, turning any moving subject into an impressionistic streak of colour and tone.

However, getting the balance right between blurring the subject and not totally obscuring its details might require some trial and error – and sometimes the subject might not be around long enough for you to capture the shot just as you'd like it.

Add your own blur
In-camera motion blur is always going to give the rest-looking result, but if you weren't able to achieve this, you can still introduce motion blur, using Photoshop Elements and any shot where the shutter speed was fast enough to capture all the detail of the subject.

In this workshop, we'll show you how to make Photoshop Elements' blur effects match the perspective of the train in our example image, so that the streaks of computer-generated motion blur flow in the appropriate direction.

You'll then learn how to apply brush tips to the blurred layer's mask, so that you can selectively reduce the blur intensity to reveal details, such as the driver and the engine's ID number.

We'll also demonstrate how to modify layer masks to help you composite in extra objects, so you can add foreground interest and extra colour to the scene.

And we'll use blending modes to add plumes of steam to help unify the separate elements in the composite image.

02 Smooth the edge
The edge looks a little jagged, so we need to smooth it. Choose Select>Inverse. Click the Refine Edge button in the Tool Options bar. Set View to On Black. Tick Smart Radius. Set Radius to 2.9 pixels. Set Feather to 1.7. Set Output to 'New layer with layer mask'. Click OK.

03 Modify the mask
Grab the Brush tool. In the Tool Options bar, choose a Hard Round tip from the Brush Preset picker. Set Size to 35. Set the foreground colour to white. Click on the layer mask. Spray white strokes to restore missing edges. Spray a black tip to hide unwanted details like the background lamp.

Top Tip
To save room, some tools share a space in the Tools panel. When you look for the Magic Wand in step 1, you may find it's not the currently visible icon in the bottom-right box in the Select section.

You can click the active tool (such as Quick Selection or Selection Brush), then pop down to the Tool Options bar.

Here you'll find a Magic Wand icon to click on. Alternatively toggle through all the selection tools in the Magic Wand's space using the handy A keyboard shortcut.

New Manfrotto compact tripods

Nobody wants to be lugging around heavy tripods in the summer, particularly on holiday, so check out Manfrotto’s new range of compact consumer-spec tripods and monopods. The Compact Light weighs in at 800g but costs under £50, and is designed for compact system cameras, while the Compact Advanced is designed for entry level SLRs with a standard zoom up to 200mm. Full details at manfrotto.co.uk.

Newbie wins street photography contest

It’s always worth a shot at entering a photography competition, as rookie Mark Heathcote discovered when he won the major prize at the recent London Photo Festival. Mark won top honours for his image of a lone passenger on a London tube train.

"What makes the picture is the juxtaposition of a red circular notice on the carriage window that completely covers the person’s face – making them look like some alien travelling around the Circle Line," said judge Colin O’Brien. Click here to see the winners.

Panasonic’s bridge compact on steroids

Panasonic's bridge compact on steroids

Bridge cameras – powerful compacts with long built-in zoom lenses – seem to have been around since the dawn of digital, but there is life in the old dogs yet.

Panasonic’s most advanced bridge is the Lumix DMC-FZ100, featuring a 20.1Mp MOS sensor and a whopping Leica DC Vario-Elmarit f/2.8-4.0 lens with an equivalent focal length of 24-400mm – that’s a 16x zoom range.

This is also the first compact camera able to record 4k video. This means 8Mp (3840 x 2160) still images can be taken from the footage. The FZ1000 is onsale mid July for £749.99. Click here to read our testing team’s hands-on review of the Panasonic FZ1000.

Suckiest holiday photographers named and shamed

Suckiest holiday photographers named and shamed

Worried about your slightly soft shots or underexposure? Cheer yourself up by checking out some really bad photography. Cheap Holiday Land.com has curated a rogue’s gallery of point-and-click abominations, with everything from decapitated relatives to cack-handed compositions.

This year’s gong (seen above) went to Jayne Boorman, who lives in Pembury, after her daughter in law Sally Boorman entered the shot on her behalf. The picture, which was taken on a family trip to Disney World in Florida, is a blurred shot of a character called Duffy the Disney Bear, a character the family took the trip to see.
