Hope someone can explain this to me.
Am reading Bryan Peterson's book titled "Understanding Exposure - Revised Edition"
On Page 39, it says:
"... since every storytelling composition relies on the maximum depth of field, you would first choose to set your aperture to f/22 and then align the distance above your distance-setting mark on the lens. Your focal length will determine which distance to choose".
1. What distance was he talking above?
2. If my focal length is 18mm (I am using Nikon 18 - 70mm lens), what is the distance?
