What is maximum aperture? Which lenses go widest (and why it matters)
What is maximum aperture? It’s a question we often hear from new photographers who are getting to grips with their lenses or trying to understand depth of field. In this guide we explain what it means to set the maximum aperture, which lenses go widest and what you actually gain in terms of your images. Click on the infographic to see the larger version, or drag and drop to your desktop to save. The aperture setting of the lens controls the amount of light that passes through, so you can use this setting as part of your exposure adjustments. In dim light you can use a wider lens aperture so that more of the light gets through to reach the sensor, and in bright light you can use a smaller lens aperture to reduce the intensity. There are other exposure adjustments too, of course, including the shutter speed, or exposure time, and the ISO, or sensitivity setting of the sensor.

Where to Focus When Taking a Photo Most beginner photographers don’t know where to focus when taking a photo, and worse still, they don’t seem to know why it’s a problem either. You may think that because you’re shooting a landscape photo, and your horizon is miles away, it’s best to focus to infinity. Wrong. What is a macro lens? Magnification and minimum focus distance explained In our latest photography cheat sheet we answer the question ‘What is a macro lens?’. In our infographic we explain some of the finer points of using macro lenses and illustrate the effects different magnifications can produce with your subjects. The official definition of a macro lens is that it should be able to reproduce a life-sized image of an object on the recording medium – in this case the image sensor. True macro lenses offer a magnification factor of 1.0x or 1:1 at its closest focus setting. Fit one of these lenses to a DSLR like the Canon EOS 60D, and a standard UK postage stamp will fill the whole frame.

An Introduction to the Inverse Square Law I don’t know about you, but I was never much of a math student. I needed a tutor in high school for both geometry and physics. I chose a double major in college (Journalism/English) that required no math. I practiced law for fourteen years, where any math I needed was either pretty easy or done on a calculator. Even when I ditched my briefcase for a camera bag and embarked on a new career, I felt pretty secure in the knowledge that confusing math had no place in the world of photography. And then the Inverse Square Law reared its ugly head. The Path to Better Photography Ed Verosky is a professional photographer and author based in New York.

You know you need a really large depth of field, and you know what you need to do to get it.
