I was taking macro shots of some components as well as shots that covered about 4 inches of components. I switched to manual focus, stopped down to f/22 and did 2-3 second exposures. Here's an example http://i177.photobucket.com/albums/w218/scompton_photos/DSC_6540.jpg[/IG][/i] [/td] [/tr] [/table] The only problem I find with using small apertures (eg F/22) is the softness caused by diffraction. It's rather obvious for night photography. If I want a relatively deep DOF, I tend to use F/8-16 and try to avoid F/22 for the above reasons. It's also difficult to properly isolate your subject (eg poor bokeh) if the DOF is so deep. |
