TTL (Through The Lens) is one of the most important elements in modern camera flashes. TTL essentially is a feature where the flash is controlled by the camera. While there is a lot of technical jargon used in explaining TTL, what you should know is that your camera will pre-decide the flash exposure. This entirely depends on the shooting conditions and the camera settings. The decision made through TTL is extremely reliable and you can easily shoot casually or during important events. However, if you are a pro handling cameras and camera-flash, you may want to purchase one that you can adjust manually, in which the control is in your hands.
Speed-light or mono-light camera-flash
Depending on whether you are an amateur photographer or a professional one, you should choose speed-light or mono-light camera-flash. The former is more versatile because it can be attached to your camera and can also be used off-camera (here the flash can be placed on a stand and paired with softboxes and umbrellas. The latter, also known as a strobe, is completely off-camera and needs to be placed on a stand. For professionals, a strobe is much more in demand.
Check the camera-flash recycle rate
How soon your camera-flash recycles is also a matter for you to consider. If you are in the habit of shooting photographs at a rapid pace, you need a flash that can recycle faster at speed. Strobes are known to have shorter recycle time. You can, in fact, reduce the recycle time of your camera-flash by using nickel hybrid batteries in your camera-flash. An added feature of these batteries is that they are environment friendly.
There are three options for you to use your camera-flash in wireless mode. If your camera supports optical triggers, you can buy a camera-flash with an optical trigger. However, TTL is not applicable in this setup. The other options for you is to buy a flash that helps you use the TTL capabilities. The third option would be to use a Pocket Wizard so that you can change your flashes with different cameras and ensure that TTL is available.
All camera-flash featured may not be meant for you
Different flashes have different features and not all of them may be applicable for you. What is important is that you find out about all these features. When you come across a feature that you don't know about, it is best to find out about it online and make the purchase if you need that particular feature. Some examples of the features available in camera flashes are auto-focus assist beam, tilt & swivel, rapid burst shooting, zooming and modeling lights. Find out what your style of photography is and make the right choice.
Get the right batteries
If you are into outdoor photography a lot, choose a camera-flash with the right kind of batteries. Choose the longest running batteries so that you are not stranded without your camera at an opportune moment. Here you need to think more about the battery than the flash.
Pay the right price for the right camera-flash
At the end of the day, you get what you pay for. The more you are willing to spend on your camera-flash, better will be the product. More price means more features and this is where your decision making will come to the fore. Thankfully, the internet offers you every possible information related to flashes and helps you make the right choice.
