What’s flash lighting?
Flash lighting or strobe lighting (monolight) as its referred to in America, is a device that emits a strong artificial light for a designated period usually in fractions of a second, to light a background or subject. The flash light will be connected with the camera so that the light ‘flashes’ just as the shutter opens and then closes on the camera, enabling the photographer to capture the perfect photograph. Flash lighting can also be paired with lighting modifiers such as umbrellas or softboxes.
Why use flash lighting
Now that we know what flash lighting is, the answer as to why you would use flash lighting should now be obvious, its to capture the prefect picture with your camera. Therefore if your camera flash is not up to the job or your work area is too dark or the light is not the right colour temperature or there are shadows in certain corners etc, then you would want to consider flash lighting to fill in the gaps and fully illuminate your subject area. More importantly flash lighting allows you supplement natural light shoots providing a more balanced controllable exposure.
What to look for in your flash lighting– a Quick 101 Buyer's Guide
Manual or TTL
All modern flash lighting now comes with TTL as standard , this is where the camera and flash analyse both the environment and camera settings to automatically set the correct power setting in the flash, if you are old school you might want the option to do this manually.
Power / Wattage
Studio flash output is measured in watts per second, we offer studio flashes from 100w right upto 600w. The AD200 Pro which is 200w will be ample for most home setups or small studios. At the other end professional or mid to large sized studios might prefer the AD400 Pro or AD600 Pro, 400w and 600w respectively. As with everything in life, more power means more money – so work to your budget and needs on this one.
A typical professional or even home studio setup will need no more than 4 flash lights, one at each corner pointing towards the subject. However if you’re on shoestring budget you can buy one powerful light and use reflectors to redirect and shape the light.
As a serious photographer you will want the ability to control how much power your flash light outputs, to either turn it up or down. This can vary quite a bit across models so choose carefully, if you need utmost control then pick any model other than AD200 OR AD600 Pro as these two adjust in 3rds whilst the other can be adjusted in 1/10 increments.
This is about how much and how quickly the light will deliver the flash, not such a big decision for portrait shots (1/3000 of a second would do) but when you are shooting action or a moving subject you will need a fast flash to capture the subject and avoid the dreaded motion blur such (as 1/10000 of a second). So make sure your model offers a good selection of settings.
This is simply how quickly its ready to fire again, again if you are taking action or moving subject shots then you want it to recycle as quickly as possible, most of our lights take 0.01 to 2.5 seconds to recycle so you are ready to shoot, with the AD600 taking up to 0.01-2.5 seconds and the AD400 in as little as 0.01-0.9 seconds.
A good quality flash light should also come with a built-in modelling lamp, basically a normal incandescent light that you can use to illuminate the subject and get an idea of how the flash will fall on the subject.
Is it replaceable and can you do it yourself? On some flash units they are not replaceable or you have to send it away to get the flash tube replaced, all our Godox flash lighting (not including the speedlights or the AD100) offer easy to replace flash tubes which can be purchased separately from our accessories section.
Most flash units will fire from either a sync cord (sold separately) or a built-in optical slave cell or a popular choice is to use a wireless slave trigger (sold separately). Personally, I would purchase a flash trigger for convenience and efficiency especially if you are working from height etc as you don’t want to be going up and down ladders to adjust your flash.
Heating / cooling
Flash lights can get extremely hot, especially after prolonged use, make sure your flash unit is of a good build quality and suited to your climate and needs. All Godox flash units (excluding the speedlights and the AD200) include built in technology to cool and dissipate heat from the device ensuring it docent overheat and is safe to use.
