What is the best camera filter to have in your bag? Mar 30th 2014, 00:01, by jmeyer A polarizer is the best camera filter to have in your bag, in our humble opinion. In this quick tutorial we’ll explain why, and show you how to use a polarizer to maximise its effects. Image by Mark Hamblin A polarizing filter is probably the most useful filter you can own and, unlike other filters, its effects cannot be replicated in Photoshop. Polarizers remove reflections from non-metallic surfaces, which makes them useful when photographing water. They also remove reflections from the tiny water droplets present in the atmosphere, giving landscapes better colour saturation. Polarizers are often used to darken the sky, giving it a more intense blue colour and making clouds stand out. The effect a polarizer has depends on the angle of the light striking the subject. They work best when shooting at right angles to the direction of sunlight and are less effective if the sun is directly behind you. They are also effective in overcast conditions to remove glare from water. Pros and cons A polarizing filter reduces the amount of light reaching the sensor, so a slower shutter speed is needed to capture the shot. This can be a positive attribute if you enjoy shooting scenes using a long exposure, such as moving water. On the downside, you usually need to use a tripod when using a polarizer, to prevent camera shake and make sure everything is in sharp focus.

A linear filter is used in combination with a filter holder fitted to the front of your lens. Circular ones come in different sizes to fit the thread of your lens, so you many need to buy more than one.   02 Set it up Using a circular polarizer is easy. Screw the filter onto the front of your lens and line up your shot, ideally with the light coming from one side. Rotate the outer ring while looking through the viewfinder or rear LCD until the polarization effect is most obvious.   03 Watch out for… Polarizers can cause vignetting on a wide-angle lens, but this can be avoided by zooming in. Polarization can also be uneven with a wide-angle view – this is most obvious in a clear blue sky. Shoot a tighter composition if this is a problem and always use a tripod.

Unlike other companies, Canon is unique in developing a complete chain of equipment that takes you seamlessly from the initial capture stage with your EOS DSLR to your final output via its PIXMA range of home printers. But what is it that really sets Canon printers apart, and which is the right model for you? Let's take a closer look. Compact, yet packed with high-end features, Canon PIXMA printers are sophisticated yet supremely easy to use, making it easy to reproduce the stunning image quality captured in-camera to the printed page. Among the most popular models in Canon’s PIXMA range are the PIXMA MG3550, PIXMA MG4250 and PIXMA iP7250. Each of these printers is based on just two ink cartridges (one black, one tri-colour) yet add all-in-one advantages for scanning and photocopying. What’s more, despite their affordable prices, they nevertheless include FINE (Full-photolithography Inkjet Nozzle Engineering) print heads to ensure premium print quality. Another standout feature of PIXMA A4 printers like these is that they use both pigment-based black and dye-based colour inks. The result is crisp, rich black text printing along with vibrant colour output. In other words, you get everything you need for document and photo printing from a single, affordable device, rather than having to buy two printers. So which of these Canon PIXMA printers is best suited for your needs? Below we’ve highlighted some of the key features of each model. PIXMA MG3550 •    Compact and stylish four-ink Wi-Fi All-In-One printer •    Print and scan using smartphone or tablet •    Google Cloud Print and Apple AirPrint support •    Dual cartridges with optional XL for extended yield   PIXMA MG4250 •    Advanced four-ink Wi-Fi All-In-One; print, copy and scan •    PIXMA Cloud Link with Google Cloud Print support •    Dual cartridges with optional XL for extended yield •    2.5-inch colour screen and memory card slots   PIXMA iP7250 •    High-performance five-ink photo printer with Wi-Fi •    Photo lab quality prints with fast output •    Low-profile design, integrated paper trays, direct disc print •    Individual, separate ink cartridges with XL options Click here to learn more about Canon’s PIXMA printer range   6 ways professional photographers use their cameras Mar 29th 2014, 12:00, by jmeyer Professional photographers use their cameras every day, so they get to know it really well and understand the best way to set it up and use it.  In their latest guest blog post the photo management and Canon Project1709 experts at Photoventure spoke to pros in many different fields to find their six most useful tips for using your camera effectively. 1. Back-button focusing By default cameras are set to focus the lens and activate exposure metering when the shutter release button is half-pressed. This works well in many situations, but if you're waiting for a moving subject to come into the frame, or for the composition to improve, you have to keep your finger on the shutter release or the focus may change from what you see in the viewfinder when you press it home. It's also easy to press the shutter release too far in your enthusiasm and take a sequence of unwanted shots. DON’T MISS: Discover how Canon’s free Project1709 platform can simplify your photo management Consequently, many pros use a technique called 'back-button focusing', which uses a button on the back of the camera (often labelled AF-on) to control focusing. Splitting the shutter release and focus control enables you to take a shot without refocusing the lens. It's especially useful when there's a danger of another object coming between the camera and the subject because the lens won't shift focus unless you press the AF-on button. Your camera's manual will explain exactly how to set-up your camera for back-button focusing, but the option you need is usually located in the Custom settings menu.
