This tutorial shows you how to use flash light for your camera the right way. It is not a big deal and most cameras have built in automatic flashes that do everything for you. But how should they know what picture you want to take and what image is in your mind?
Right, they don't know, and that is why you should have to know how to flash right for full control of the automatic flash!
I came up with this when I started to use the slave flash that I built. You can find the original instructable here:

In the meantime I even built a second version of it that is much smaller and much cheaper and easier to built:

So now, let's get started!

Signing UpStep 1Aperture - time (and flash ?)
When taking pictures you have different options to get a correct lighted image on film or on sensor. The principle is all the same.
You can vary either the exposure time, the aperture of your lens or the sensitivity of your film / sensor. While you normally only change the first two, because it is enough freedom to get good pictures.
The pictures of this step show you what happens when you chose shorter exposure times for a given situation and aperture. In the lower right corner of each image you can read the exposure time, the aperture and the iso-sensitivity.
The first picture has a correct exposure, the other ones are more or less under-exposed.
But when a flash is involved the degrees of freedom are reduced because you have an additional light source that can only be adjusted in a very small range (see next step).

I honestly thought this would be about roofing...

Thanks for the hint!
I like language, it's a double entendre.
