Basic DSLR Training Flash

This Blog is about Basic DSLR Training Flash. There are two ways to provide light from a flash.

  1. The pop-up flash found on the domestic DSLR.
  2. By using a flash gun that you buy as a separate unit. You can use this on the domestic and pro DSLR cameras.

POP-UP Flash

To begin with you find the pop-up flash on the domestic DSLR camera. To activate the flash you push its button or it pops up automatically when called for.

Generally speaking you us a flash to add light into a photo. In this case where the subject has there back to the sun and a little light will lift the shadows. When you are in a dark room and you need light to see the subject.

Disadvantages of the pop-up flash

The big disadvantages with the pop-up flash are:-

Red-Eye.

In reality the pop-up flash is mounted in a fixed position, above the lens meaning the flash is thrown forward.  As the flash fires so quickly the pupil cannot close, the light passes to the back of the eye and bounces back.  As a result there is a greater chance of having the red eye look, in the eyes. In this case you can get rid of this by using digital photo software.

Flat Photo.

As a result of a fixed flash this means that you can only direct the light straight forward. In contrast this causes a lack of shadow in the image. In addition this gives the appearance of the photo looking flat (harsh) and having no definition.

By all means to reduce the harsh light you could use some equipment accessories available to lessen this.

Flash Guns.

In this case this type of flash fits in the camera hot shoe or can be used off camera. At the same time if you use it on camera the same disadvantages are present as in the pop-up flash. For this reason better diffusion is available and it can be turned or lifted (bounced) to soften the light.

Use the flash off camera by using either flash cords or infra-red/radio triggers.

For this reason the big advantage with this is that by adjusting the light output of the flash you can create shadow across the subject. In addition by using two or more flash guns you can produce stunning photos. It must be remembered that this is not possible at all with a pop up flash.
