Yes, it's true you can't bring objects into focus with PhotoShop – at least not to any great extent. But using tilt for DOF is really only a factor in large format photography, where DOF is extremely limited. With a 16 x 24 sensor, extensive DOF is easy to achieve.Tilt would be relatively useless in this case, except perhaps for macro
photograph. And even in that case, the entire camera can usually be
tilted to achieve matching focus.
limited depth of field is a major issue for me in short-range (not
macro), shots; it's the main reason i'd even consider a tilt lens;
tilting the camera doesn't make nearly a big enough difference in focus
distance in such shots so i use the limitations as a creative foil --
forces me to think more about perspective; however if i got to the point
where i were patient enough to use a tripod for such scenes, i could
also see using a tilt-shift to work the depth of field -- usually to
increase it rather than to get the "toy scene" effect
and on the flip side creating an out-of-focus effect in Photoshop can
require extensive masking if you have scene where not everything is in
the same plane
There's a reason why no one is producing new tilt/shift lenses for DSLR cameras.
i guess the LensBaby fad doesn't count?
