DIY Photography
Painting with light is a fun technique that gives great results. It is called painting with light because this is what you are actually doing while taking the shot - painting with light.Basics - Aperture
Aperture is one of the three main controls you can use when you are taking a picture. Along with shutter speed and ISO, aperture controls how light will hit the sensor (OK, old schoolers - hit the film).In the previous few articles, I have discussed some basic aspects of photography. The first subject to get a close look was exposure , and I have discussed two of the three components that control it: shutter speed and aperture . In this article, I will bring in the missing piece - ISO (or film sensitivity).
Basics - ISO
After talking so much about exposure and the controls you can use to, em.. well... control it, I thought I'd bring up some info that can help bring all the control info together.
