Light & Motion has posted on their website part one of a video seminar by Steve Fish, which talks about wide angle lenses, depth of field, focus lock, filters, and white balance. You can also sign up to be notified when part two of the seminar is posted.
Very good seminar. One clarification please. Under the second paragraph of “LOCK YOUR FOCUS” he mentions momentary auto-focusing at something with good contrast at about 3 ft. away which then locks the focus on that distance and your depth of field will make everything sharp from a few inches to “ABOUT AS FAR AS YOU CAN SEE”? Would it not be sharp from where you focused on in to a few inches? I’ve been doing this but focusing much further out so that everything from THERE in is in focus (but maybe that is unnecessary). Would this work or is it a typo? Thanks.
