Interesting response, PDL.
Originally posted by PDL I use selective focus all the time - nearly every image. To repeat my self - I have de-coupled AF from the shutter button on both the K10D and the *ist Ds. Rarely do I have the main subject - dead center - in the frame, it's called composition, which I prefer to do when shooting and not during the PP phase.
I agree that composition is something that one should always try to do at the time of shooting, if for no other reason than that it's a waste of pixels to rely too much on cropping.
But we have more than two choices here, no? I mean, it's not a simple choice between using selective focusing while shooting, OR shooting subjects that are always in the dead middle of the frame and perhaps cropping later to make the picture interesting. You can focus and recompose, it's easy to do, and even with selective focus, you HAVE to do it sometimes, because there are only 11 points and as somebody else already mentioned, they're kinda bunched in the middle of the frame.
Quote: I always use the center focus point also. Why? It is the same mechanism that I used on my manual - split image - focus film SLR's that I have used since the very early 70's. Old habits die hard, I used to shoot sildes almost exclusively, so I had to compose the image in the camera - otherwise the 10 foot wide picture looked --- just plain bad.
But now I'm confused. If you
always use the center point, then how is that different from using center-spot focusing?
And those old split-image focusing screens -- which I also miss -- required that that subject you were focusing on be in the middle of the frame, because that's where the image was split. So back then, your only choice was to focus and recompose. That experience is in my own background and may have something to do with my asking now, what's the point of selective focusing?
Let me say for the sake of clarity: I'm
not asking why anybody would ever want to focus on something that isn't in the middle of the photo. I'm simply asking why you'd need the selective focus option to do that. A couple good answers have been provided now (although they involve doing things that I just don't do very often).
One more point about composition and selective focusing. I shoot a lot of sports, as well as other events where I don't have much time to get arty about the focus and composition. When I see a nice opportunity to focus off-center and put shallow depth of field to good use, I'll take it if I have time. But I often don't have time. I've tried shooting volleyball using AUTO option for AF focusing. The user's guide says about this option that it "selects the optimum AF point even if the subject is off-center." But the camera's idea of "optimum" often turns out to be different from my own. ;-)
Quote: Only when I am shooting something that is at is pretty far away from me do I just focus at the center point. Although I have been known to focus on something close and adjust the DOF to include objects in the background. Ah -- the good old days, when you could actually see the DOF engraved on the lens. Back when the only computer associated with the camera was the one behind the viewfinder - when you had to "think" not just blast away and blame the camera for not getting "the" image.
I remember those days myself. I remember when I had to guess the metering on everything because I didn't usually
have a light meter with me. I took even more lousy photos back then than I do today. ;-)
