I'd appreciate any input people have for the photos below. Just learning how to use all the features on my XTi. Also have been fooling around with trying to control the DOF with just the f-number (using a 100-300 lens- usually near 300) and have not been too impressed with the shallow end- things just don't get that blurry! Reference the last two pictures- first one wide open (5.6 I think?), and the second one at f/40. What else can I do to decease the DOF? I'd like to see the objects behind the subject be very blurry so they don't distract at all... Thanks! 1. 2. 3. 4. 5. 6. 7.
