Have you ever had problems with pictures being over or under exposed? I’d love to help you understand why it happens and how to compensate for it.
Today is Part 1 in a series to help you tackle this problem.
I’m going to start by quickly touching on the different factors that affect a picture: Tv (Time Value), Av (Aperture Value), or ISO (speed of the ‘film’).
At the end of today’s post, I’ll leave links to older posts on Av, Tv, and ISO that go into more detail on each of them.
Once you understand how the Time, Aperture and ISO affect your photos, you will have some options for correcting the over/under exposure problem.
