Like most DSLR cameras, the Canon Rebel T6, or the Eos 1300D, is equipped with an internal flash and an external flash shoe. The built-in flash is very useful for occasional photography, with family or friends. It has a GN (indicative code) of 90, which means that it is effective over a distance of about 2 to 3 meters under normal settings (100 ISO, f4). The advantage of the built-in flash lies in the fact that, built into the camera, you always have it with you. It is automatically dedicated to producing the best possible exposure, using the ETTL (Evaluative Through The Lens) system of the camera. the camera shares its exposure settings with the flash so that the picture looks beautiful. This is especially useful if you are using the flash to fill. The other advantage is that if you use the basic modes (automatic shift to night portrait), the camera will decide if the flash is required, so you will not have to think about it.
There is also an option to trigger the flash, even if the camera thinks you do not need it. The options you can change are limited compared to the external flash, but a helpful choice is the front curtain or the back curtain, as this will affect how your action photos are taken. if the flash is set to the first curtain, it will fire as soon as the shutter opens. If the flash is set to the back curtain, it will fire just before closing the shutter. It may seem unimportant, but if you are shooting fast-moving subjects, the flash fires seem like the subject is moving backward (because the subject is frozen by the flash, then there is a ghostly movement as the subject goes from the front). If the flash fires at the end of shooting, the ghostly motion occurs first and the subject is frozen by the flash, which makes it as if it was moving forward.
You can also change the exposure compensation settings and the ETTL chooses an evaluation or an average. In this case, Evaluative will set the flash according to the light on the subject, while Average will set the flash according to the average of all the light in the frame. Since the flash uses ETTL, it knows the lens settings. It therefore focuses the flash light if the lens is zoomed (50-100 mm) or scatter it if the lens is over a long focal length (24 mm, for example).
There are more creative options for the external flash, although it depends to some extent on the flash gun you have.
In both cases, you have the option of changing the sync of the front curtain (first) or rear curtain (second). The front curtain triggers the flash when the shutter opens and the rear curtain triggers the flash just when the shutter closes. If the subject is still, it does not matter, but if the subject is moving, the flash firing affects the movement print on the picture. Off-camera flash options can also provide high-speed sync, which allows you to take pictures with bright light and shallow depth of field. With both flash options, you get flash exposure bracketing (FEB), which allows you to fix your photos in square brackets. Take the same picture with a different flash intensity, then choose the one you prefer.
If the external flash has ETTL settings, it will also respond to the lens zoom setting. This is very useful because if the lens is set to a wide angle, the flash will try to scatter its light over a wide area, whereas if the lens is long, the flash shrinks the beam of light to try to get more light. distance. In many cases, the external flash will also work as a slave flash, which means that you can place it away from the camera and that it can be triggered by the built-in flash of the camera .
