How Autofocus Works in Photography

When it was first introduced, many people sharply believed that autofocus would never have a clear place in the photography industry, puns intended. Why have a machine guess where to focus when you can just turn the focusing ring yourself? Today, autofocus systems are among the primary selling points for new camera and lens technology.

Glossy vs. Matte Photo: Which is Best for Printed Pictures?

ISO in Photography: A Complete Guide

When compared to the other components of the exposure triangle (shutter speed and aperture), ISO appears to be the most intuitive on the surface. It is also the most misunderstood component, and everything from its definition to its usage has been discussed extensively.

Shutter Speed in Photography: A Complete Guide

As perhaps the most important parameter to understand in photography, shutter speed should be one of your first considerations when making a photograph. It’s one of the biggest reasons that photographers might find themselves unhappy with their shots, and having a great understanding of it is crucial to making great images.

What is a DSLR Camera?

If it seems like there’s more new photography technology than what you can keep up with, you are probably correct. However, don’t let that deter you from learning the industry standards and terms within it. One of those terms that you’ll likely come across is the digital single-lens reflex (DSLR) camera, which has been the leading type of camera for still photography throughout the past decade.

What is a Mirrorless Camera?

There is a constant push for faster and lighter technology across different industries, including laptops, smartphones, drones, cameras, and more. In the photography world specifically, mirrorless cameras have appeared on top of the race to overtake DSLR cameras as the industry standard camera for still photography.

What is Focus Peaking? A Guide to the Manual Focusing Aid

When using manual focus, it’s difficult to tell exactly where your plane of focus is. It’s possible to make a guess using your eye, but you can still be slightly off and end up with an image that is out of focus. Similar to how histograms take the guesswork out of exposure, focus peaking uses an algorithm and a simple visual aid to help take the guesswork out of manually focusing your lens.

What is EXIF Data in Digital Photos?

In the digital age, there’s a lot more to a photograph than the image itself. When most digital cameras capture an image, they record certain parameters and write them in the image’s file for later use. These parameters are called metadata and are stored as Exchangeable Image File data, or EXIF for short.

Histograms in Photography: A Guide

If you didn’t believe your grade school math teachers when they said you’d use graphs in the real world, you’re about to. In photography, histograms can seem intimidating, but they are incredibly useful tools that are much easier to understand than they appear. Learning about histograms will help you understand exposure, post-processing, and the overall structure of a photograph.

How to Clean a Camera Lens

Realizing that your lens was dirty during a shoot is not a great feeling. While some specks of dust and other consequences of a dirty lens can be fixed via spot healing and other post-processing, it’s much easier to make sure your lens is clean to begin with and save editing time. Plus, attention to the state of your lens will help it retain its value over time and increase its longevity.

How to Use Bulb Mode on a Camera for Long Exposure Photos

When you hear “long exposure,” you probably think of a shutter speed that’s too slow to hand-hold and produce a sharp image. It might be something like ¼”, or maybe as long as 30”, which is the most common slowest shutter speed in DSLR and mirrorless cameras. However, shutter speeds slower than 30” can be advantageous in many long-exposure scenarios.
