[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]Hi George and Frank,
Number 1 was photographed with a Tilt/Shift lens. I think the problem is
that the foreground and background are in focus because they are in the
plane of focus?produced by the tilt. The mid-ground area was down a cliff; a
drop of 20 - 30 feet. As this would put it out of the plane of focus created
by the tilt, the only way to try to get it in focus is through reducing the
aperture. I believe I should have shot at a smaller aperture than?f8, and
that may be the cause of?the slop you see.
I think?this would explain it as the right side was futher below me than the
left and, as Frank noted, the right side seems more out of focus. I think
the shift was centered.
Does this make sense to you?
Thanks for pointing this out. I'll?just have to go back! :-)
George, as for the darkness in the the other shots, it's not caused by any
adjustments by me. Pt. Lobos has a huge dynamic range. I could never get
anything when I shot Velvia?nor negative color. Even using N-2 with BW film
couldn't get it all. I had a .6ND Grad filter (I'm going to be buying a .9
now) and even with all that an the increased capture dynamic range of
digital, I couldn't get it.
So thanks for the input very much. Numbers?4 and the last image will be put
on my main gallery!
Best,
Bob

Bob... were you using your perspective controlled lens for the first shot?
Does the lens offer swings and tilts?? Or Tilt only?? ( relative to a
landscape image configuration.)
Mid range focus on the right worse than midrange on the left.....? indicates
maybe your lens was not "centered" and set for some amount of tilt.... which
in this composition means swing... and therefore the focus planes are not
where we expect them.....? Although it certainly works for the
foreground.....
Is this just a case of focus distortion caused by the foreground focus being
right ( which it is) , and the background wrong for the foreground focus
planes.....?
Sometimes swings and tilts make the focus just look weird....
Certainly a colorful shot.... nicely composed.

the first - the mid frame lack of focus puzzles me
Fond regards,
