Practice, practice, practice!
Anyway, with that bad joke out of the way here's what I do.
Surprisingly enough to many, I actually focus on the eye(s)! What a
concept! Also, I do not use the center point most of the time. I
select a focus point which would normally be on or around the eye
which greatly reduces camera swing when I'm recomposing the shot.
(How I love the improved focus system of the 10D, I shot with a D30
to learn the digital work flow and it was..... challenging.) I do
use the center point when I'm shooting a moving subject using servo
focus mode. Other than that, I am in one shot focus, I select a
focus point on or near the area of critical importance, and I
listen for the beep. (I'm near blind now, Stevie Wonder would do a
better job of manually focusing than I would!)
Eyes are easy, they have a lot of contrast particularly because the
eyelashes provide verticals while the eye lid provids horizontal
lines of contrast. I also pick one, not the center of the face so I
am actually focusing on the eye. Note in this picture one eye has
hair in front of it, I didn't choose that eye. Another thing I want
to point out is that as I have used this camera I have become more
aware of how important shutter speed is if you want crisp pictures.
This picture was shot with a 70-200 2.8L zoom set at 200 mm, on a
tripod at 1/180 of a second. I try not to hand hold this lens any
more at shutter speeds below 1/350 of a second. I was using a
studio strobe (outside) with a soft box attached so I had the
luxury of f13 when shooting, still the strobe I use for location
work is an Alien Bee 800 (hate dragging my Speedo's around) which
only uses a 100w standard household light bulb as a focusing lamp.
Even in this low light the EOS 10D focusing system was up to the
task.
Yes, depth of field helps, particularly if you have selected your
focus point correctly in the first place. I do a lot of shooting at
f4 or lower with long lenses (it is the nature of my work, I don't
want the backgrounds to compete with the subject). I have posted
this shot before, but here it is again shot with the 70-200 2.8
zoom (Non IS) at f4, hand held at 1/500 of a second. And at f4
with a lens this long there is a difference in the sharpness of the
eye on the left (where I focused) compared to the eye on the right.
Technique counts, these are extremely complex electronic systems
which are capable of incredible accuracy quickly(far better than
most of us on full manual), but you have to learn how to use them.
In closing the 10D is an amazing product for the price. It has
given me and a lot of other pro's the luxury of walking away from
film. I'm in the process of getting a 1Ds, but I could not wait to
buy the 10D because it was obvious from the moment it was announced
that Canon had given us a tool which we could put in our bag and
not feel embarressed when we pulled it out. I only pray that the
Nikon D2x arrives soon and is a great camera so that there is some
pressure on Canon to drop the price of the 1Ds.
