The other day I was talking to a friend about photography and was trying to explain the concept of how depth of field works and how an aperture controls DOF. He was asking me how to make image backgrounds fuzzy in Photoshop, he didn’t understand I had done it in camera. With our automatic cameras, I understand people really become lazy and do not understand how changing a shutter speed or aperture settings can change their photos. I went over to one of my favorite websites, Deviantart.com and shared a tutorial I had bookmarked a while back, to explain the concept. I know for me personally, I shoot 95% of my work in aperture priority mode. So for me, I think it is important for others to understand this concept.

Also check out this link for many more excellent tutorials. They have done a great job of clearly explaining each concept from Macro Photography to High Contrast Black n’ White
