Like most digital SLR cameras, the Canon Rebel T6, or Eos 1300D, has a built/in flash in addition to a hotshoe for an off-camera flash. The built-in flash is very good for informal photography, perhaps of family or friends. It has a GN (guide number) of 90, meaning that it is effective over a distance of about 2-3 metres under normal settings (100 ISO, f4).
The good thing about the built-in flash is that, being built into the camera, you always have it with you, and it is automatically committed to produce the best exposure, using the camera’s ETTL system (Evaluative Through The Lens), which means that the camera shares its direct exposure settings with the adobe flash so that the picture looks good. This is particularly useful if you are using the expensive 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 need not think about it Canon Rebel T6 review.
There is also an option to help make the expensive fire, even if the camera doesn’t think you need it. The choices you can change are limited compared to the external flash, but one useful choice is front curtain 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 open fire as the shutter opens.
When the flash is arranged to rear curtain, then the flash will open fire just before the shutter closes. This might not appear important, but if you are shooting fast-moving subject matter, 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 matter moves forward). If the flash fires at the end of the photo, the ghostly movement happens first, and the subject is frozen by the flash, which makes the subject like they are going ahead.
You can also change the exposure compensation configurations and the ETTL choosing either evaluative or average. In this instance, Evaluative will set the expensive according the light on the subject, whereas Regular will set the flash according to an average of all the light in the frame. Because the flash is using ETTL, it knows the lens settings, so it will concentrate the expensive light if the zoom lens is zoomed (50 -100mm) or disperse the light if the lens is on a wide key length (24mm, for example).
With both you get the option to change the flash synchronization – either front (first) drape or rear (second) drape. Front curtain fires the flash as the shutter release opens and rear drape fires the flash just as the shutter closes. In the event the subject is stationary, then that won’t matter much, however, if the subject is moving, then when 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 Exposure Bracketing (FEB), which allows you to bracket your shots – shoot the same picture with different expensive intensity, and then decide on the one you want.
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 over a wide-angle setting the adobe flash 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 beam 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.
