What is Aperture?

Having had to explain the Exposure Triangle so many times to my friends, I decided to do a series of movies on the Trinity of Photography (Aperture, Shutter Speed and ISO). This is a 3-part series on how to shoot photos (or videos) on Manual mode ... like a pro. Part 1 below is devoted to Aperture.

Part 2 will be on Shutter Speed and Part 3 will be all about ISO. Also in Part 3, we will combine all the knowledge we have on Aperture, Shutter Speed & ISO to start taking photos in Manual mode. Only in Manual mode will you have full control of your camera.
