i am using a canon 50mm f1.8 lens . i love the effect when i am taking close up on object or faces with the background blurr . but when i try to take a full body of a person the background seems to be clear too . any setting i can do to make the background blurr ?
hope some kind hearted pro could give me some help thanks alot
You didn't mention what camera you are using, but i'll assume it's one with a cropped sensor.
By trying to get a full-body portrait, what you're doing is stepping back, thus increasing Distance A (with reference to Sulhan's diagram) but with no change to distance B.
With a 50mm lens on a cropped body, I'd assume you'll be quite far away from the subject. Thus the depth of field has effectively increased, rendering the background sharper.
but i guess you already knew the answer....
