Like most digital SLR cameras, the Cannon Rebel T6, or Eos 1300D, has a built-in flash as well as a hotshoe for an off-camera flash. The particular built-in flash is very good for everyday pictures, perhaps of family or friends. It has a GN (guide number) of 90, meaning it is effective over a distance of about 2-3 metre distances under normal settings (100 ISO, f4).
The good thing about the built-in flash is that, being built into the camera, an individual always has it with you, and it is automatically committed to produce the best exposure, using the Canon Rebel T6 review (Evaluative Through The Lens), which means that the camera shares its direct exposure settings with the flash so that the picture looks good. This is particularly useful if you are using the adobe flash to fill-in. The other advantage is that if you are using the Basic Modes (automatic through to night portrait), then the camera will decide if flash is required, so you do not have to think about it.
There is also an option to make the adobe flash fire, even if the camera doesn’t think you need it. The choices you can change are limited compared to the exterior flash, but one useful choice is front drape or rear curtain, because this will have an effect about how your action pictures are shot. if the flash is arranged to first curtain, then the flash will fire as the shutter starts.
In the event the flash is established to rear curtain, then the flash will fireplace just before the shutter release closes. This might not seem to be important, but if you are shooting fast-moving topics, firing the flash first will make it look like the subject is moving backwards (because the subject is frozen by the flash, and then there is some ghostly movement as the subject moves forward). If the flash fires at the end of the photo, the ghostly movement happens first, and the issue is frozen by the flash, which makes the subject like they are going forwards.
You can also change the exposure compensation configurations and the ETTL choosing either evaluative or average. In this instance, Evaluative will set the flash according the light on the subject, whereas Regular will set the expensive according to an average of all the light in the frame. Since the flash is using ETTL, it knows the lens settings, so it will concentrate the flash light if the contact lens is zoomed (50 -100mm) or disperse the light if the lens is on a wide focal length (24mm, for example).
With both you get the option to change the flash synchronization – either front (first) curtain or rear (second) curtain. Front curtain fires the flash as the shutter release opens and rear drape fires the flash just like the shutter closes. In the event the subject is stationary, then that won’t matter much, although if the subject is moving, proper the flash fires will affect the impression of movement in the picture.
The off-camera flash options may also offer High-speed Sync, which allows you to shoot pictures in bright light with a shallow depth of field. With both flash options you get Flash Publicity Bracketing (FEB), which allows you to bracket your shots – shoot the same picture with different flash intensity, and then choose the one you prefer.
If the external flash has ETTL settings, then it will also respond to the zoom setting of the lens. This is very useful as, if the lens is on a wide-angle setting the expensive will try to spread out its light over a wide area, whereas if the lens is on long setting, then the flash will narrow the ray of light to try to get more distance. In many cases the external flash will also operate as a slave flash, meaning that you can place the flash away from the camera, and it can be brought on by the built-in flash on the camera.
The particular Canon 1300D, or Digital rebel T6, is a superb camera for learning how to use flash in your photography. Watch this video here or visit my website to learn more.
