I’ve written this article assuming that many readers will already own a speedlight but, for those who don’t, I hope that it will be useful as information on what to look for when buying a speedlight. There are many online buying guides and reviews to help choose the best for your budget.
What is a speedlight?
A speedlight is a specific term for a small light which can be mounted onto your camera. Typically powered by AA batteries, these lights are budget-friendly, highly portable and are available in a range of sizes and power outputs. Also sometimes called a flash gun, camera flash, spelled ‘speedlite’, or simply a flash by lazy people like me. This is the type of light that this article will focus on.
A strobe is larger and more powerful than a speedlight. Strobes are normally seen mounted on their own light stand and cannot be mounted onto a camera hot shoe. They can be mains or battery powered. Typically, they can produce lots of light over a short period of time and often feature a continuous light called a modelling light/lamp. They’re sometimes called a monolight. I won’t be covering strobes within this article, but I do offer tuition for both speedlights and strobes.
The most obvious use for a speedlight is to light a dark subject but arguably better uses would be to guide the viewer’s eyes, to improve the quality of the photograph and to influence a scene. A speedlight can be used to freeze motion, separate a subject, and to add vibrance and contrast to an image. Used creatively, a speedlight can add direction or colour to light, or be used in a multi-light setup. They greatly increase your flexibility as a photographer and will help you capture a wider range of subjects, especially in less-than-perfect lighting conditions.
What about your built-in camera flash? Some people might tell you this is useless, but there are a few things you can do with it. Using the built-in or pop-up flash as-is will result in a flat, brightly exposed photo with hard shadows and red-eye in a portrait but you can try to bounce or diffuse this light to soften it and get a much better result. Try searching online for pop-up or built-in flash hacks to get some ideas. However, this built-in flash is limited and will not produce the same results that a speedlight can.
Terminology
WARNING: JARGON ALERT!
Jargon has got to be the most off-putting part of using speedlights. Don’t let it stop you learning! I’ve tried to explain all of the horrible sounding terms as best as I can in this article and I’m hoping that this will help you achieve those wonderful epiphanies or ‘ah ha!’ moments.
I don’t know whether you will find this encouraging or not, but I think speedlights are the hardest to learn of all the lighting types. So, once you’ve got the hang of your speedlight, you should find strobes a breeze.
Here is a handy table of terms that you may see on your speedlight or in the menu. If you have an older or more basic model flash, some of these options may not be available. I will explain many of these terms further throughout this article although some refer to more advanced functions, like off-camera flash, which I will cover in a later article.
