4 ways to get the best effects possible from your polariser filter Aug 31st 2014, 23:01, by jmeyer With the advances in post-production software, it's now possible to do almost anything to your images after you've fired the shutter, but there's one filter that's difficult to replicate effectively, and that's the polariser filter. In this tutorial we show you 4 simple ways to use your polariser filter to its maximum potential. A polariser filter has many uses, but its primary function is to reduce the amount of glare from non-metallic reflective surfaces such as water. It also removes the small reflections from leaves and other foliage, saturating the colour and giving the landscape extra punch. Its other main use is for intensifying the colour of blue skies and making white clouds stand out. A polariser also helps to reduce atmospheric haze.

These come in various diameters, and you'll need to buy one for each size of lens you own. A slot-in polariser, such as from Lee or Cokin, is used with a filter holder.  SEE MORE: 9 filter mistakes every photographer makes (and how to avoid them) How to use one The effect of a polariser can be seen by rotating the filter on the front of the lens or in the holder. The degree of polarisation depends on your shooting position in relation to the angle of sunlight. It's most noticeable when you're photographing at a right angle.

A polariser reduces the amount of light reaching the sensor by upto around two stops.  SEE MORE: 4 tips for using your polarizer to shoot the perfect sky Watch out for… Polarisers often produce uneven results when using a wide-angle lens because some parts of the sky are more polarised than others. It's most noticeable in a blue sky, with the more polarised area appearing darker. The effect can be lessened by increasing the focal length.

This Week in Photography – news from 25-31 August Aug 31st 2014, 10:00, by jmeyer Welcome to our weekly photography news, with all the latest stories that matter to serious photographers. Selfie-friendly Olympus PEN E-PL7 unveiled Olympus has unveiled the Olympus Pen E-PL7. This 16.1Mp metal-bodied compact system camera features a selfie-friendly LCD that "flips down and around so you can frame and shoot a series of pre-timed, sequential still or video selfies without your hand blocking the shot," according to Olympus. The E-PL7 also includes a 3-inch, touchscreen LCD, 3-axis image stabilisation and built-in WiFi, which also enables the camera to be controlled via a smartphone. The PEN E-PL7 goes onsale in late September for £499.99 and includes a 14-42mm f/3.5 pancake zoom lens. Read our head of testing's Olympus PEN E-PL7 hands-on review here. Pentax K-S1 DSLR revealed Pentax has revealed a new DSLR called the K-S1, with a 20Mp APS-C sensor and an LED body illumination that stays green when shooting stills but changes to red when shooting movies. More conventional features include an ISO range of 100-51,200 and a maximum shutter speed of 1/6000sec. There is a slightly bizarre choice of colours based on Pentax’s ‘Fabric’ range, including tweed grey, which will doubtless appeal to members of the aristocracy, and denim, which will doubtless appeal to Iron Maiden fans. New Fujifilm X30 premium compact unveiled Fujifilm has released a new premium compact, the X30, featuring a 12Mp, 2/3-inch CMOS sensor. The camera replaces the X20 and also includes an articulated (but not touchscreen) three-inch screen and an improved electronic viewfinder, featuring 2.36 million dots and a display time lag of only 0.003 seconds. The lens has a fast aperture range of f/2-2.8 and 4x optical zoom. There is also a manual control ring to adjust aperture and shutter speed, and 12 frames per second continuous shooting mode. Fujifilm claims the battery can now shoot 470 images on a single charge. The X30 goes onsale in late September for £479 and comes in black or silver.

New Manfrotto travel tripod The Befree Carbon, a new Manfrotto carbon fibre tripod for travel photographers and others needing lightweight support, has been launched. The BeFree Carbon weighs only 1.1kg while its foldable legs reach a folded length of just 40cm. Such portability doesn’t come cheap though, and the new tripod costs £279.95. DxO Optics Pro 9.5.2 update Version 9.5.2 of DxO Optics Pro has been released, with the Elite Edition adding support for the highly acclaimed Nikon D810 SLR. The DxO Optics Modules library has also been expanded, and now offers 894 new camera/lens combinations.
