If you’re a beginner photographer, then chances are you’re a bit stumped by the relationship between the aperture value and the size of the aperture.

Beginners who have attended the Getting Started in DSLR Photography workshop we run will be familiar with this relationship and what it means to both depth of field and exposure control. For photographers working hard to teach themselves, the notion that the aperture value (f-number), the wider (or larger) the aperture can often be confusing – because it appears counter-intuitive!

Well, scratch your head no more — this video, presented by Mark Wallace, explains why this is so in normal, everyday language. Sure, there is a bit of maths involved but nothing too brain draining. If you’re still wondering what the “f” stands for and why the number to aperture size thing seems topsy turvy, do yourself a favour and watch it.
