Photography composition tips: 3 killer ways you can master perspective May 15th 2013, 23:01 Learn how to take control of perspective in your photo composition. In this tutorial we offer our best photography composition tips through your choice of lens to shooting position so you can start making perspective work for you. For artists and draftsmen learning how to create a sense of perspective is one of the first disciplines to master. In a nutshell it's the art of rendering the three-dimensional world that we see around us onto the two-dimensional surface of paper or canvas. Of course, this is also what we do when we take photographs, but because the camera essentially does the work for us it tends to get overlooked. However, being aware of some the basic principles will help you understand how the elements of your composition work. Knowing how lines draw the eye in and can be used to create a sense of distance can make you a better photographer. While it's tricky to manipulate perspective 'in-camera' in the way a draftsman might play with it using pen and paper, there are aspects that you can control through your choice of lens, angle-of-view and your distance from your subject. You can choose whether buildings appear plumb-straight or 'keystoned' in your shots, and decide how much of the background to include in photographs of people and objects. You can even play with perspective to create entertaining optical illusions. So let's see how you can use perspective to take control of your picture taking… PAGE 1: What perspective means to photography PAGE 2: Photography composition tips – Linear perspective PAGE 3: Photography composition tips – Background PAGE 4: Photography composition tips – Perspective of scale READ MORE 15 common photography questions from beginners (and how to solve them) Color Theory: best color combinations for photography (and how to take it further) 99 common photography questions (and how to solve them) 10 common camera mistakes every photographer makes Refraction of light: capture amazing photography effects with a glass of water May 15th 2013, 11:37 The refraction of light is one of the most commonly observed phenomena and is a perennial favourite of photographers. While talk of bending light waves and the effects they produce may sound like complicated work, it’s actually a rather simple photography effect you can recreate anywhere. Find out below how to capture the refraction of light using a glass of water and a cool background! In this tutorial we're going to use the refractive properties of glass and water to make a striking arty abstract. The chances are you witness this effect every day, and it can be clearly seen by simply looking through a glass of water. But we're going to take it one step further and control the effect for creative results.ding light Using a background of diagonal black and white stripes, we'll use the distorting properties of water and glass to bend, twist, rotate and skew the lines to form intriguing abstract shapes. This is a relatively easy technique to get to grips with. Simply fill a glass container with water and look through it – you'll instantly see the distorting effects of refraction in action. Layer several glasses in front of one another and you'll add layers of distortion to the overall effect. The lighting is straightforward, and a regular camera mounted flashgun bounced off the ceiling will be more than adequate. You don't need any fancy equipment or complicated camera techniques to achieve amazing results. A simple table top is all you'll need. So let's get started and see how it's done… How to photograph the refraction of light Get started For this project you'll need to make a simple background. We've created a diagonal black and white stripe in Photoshop and printed it out on a regular office laser printer. It doesn't need to be too fancy. It's worth experimenting with different designs, or you could even introduce some colour.   Perfect your settings Position super-clean drinking glasses in front of the backdrop, and fill them with water to varying levels. Use a small aperture such as f/16 to maximise the depth of field and ensure everything's sharp. Use a tripod, as small changes in camera angle will affect how the glass and water refracts the pattern.   Prepare the lighting Daylight can work perfectly, but we'll be using a flashgun here as we're shooting in lowlight conditions. Ideally you want to avoid any unsightly reflections on the glass – you can easily achieve this by bouncing the light off the ceiling. To do that, simply point the flashgun in the up position.
