I'm working out how to mimic large format camera movements, which as most fo you know, create an ethereal, ghostlike selective focus... Does anyone have any tried and true methods that accurately get this effect in photoshop? or maybe know of any helpful links?

and dont say "gaussian blur" and apply a layer mask, because no that does not look right...

im gettin terribly frustrated with this one...

Buy a lensbaby.

Would this work?

Dave Beaman's Ethereal Glow or is that the effect you are not liking?

Link to the PS Action

Physically, that is the best option.

i get your point..
however, i do freelance retouching for some clients... if they request that effect (as in, right now, the creative director ofa local magazine wants me to do it to some photos) .. i need to be able to pull it off

thank you for trying, but not thats not the right look... that action seems to me to be some blurred overlays...

i also dont *love* lensbabies (having tried one recently) because I prefer how specific i can be with my movements on the view camera... lensbaby kinda feels more like a holga to me...

i guess old school analog cameras aint dead yet ;)

I'm not quite sure what you mean by "an ethereal, ghostlike selective focus." It is true that a large format camera will have a longer focal length normal lens and thus will have a shallower depth of field. This has nothing to do with the movements; it is a direct result of the focal length of the lenses being used. You will find it easier to get shallow DOF with full-frame sensors and fast lenses. You are right about this being difficult to simulate with Photoshop.

There are two things I do with the tilts and shifts. First, I correct for perspective distortion. When I shoot a building, I don't point the camera up at the building. Instead, I level the camera and then raise the lens to get the top of the building into the image. The perspective corrections in Photoshop can do essentially the same thing.

I also use the Scheimpflug rule to shift the focal plane. Normally when you focus on something a certain distance away (say 10 feet), everything that distance away is in focus. But if you twist the lens, on one side the image closer objects will be in focus and on the other side more distant objects will be in focus. This is really useful if you are shooting a line of people from an angle. There is no way to do this with Photoshop.

If this is important for your work, you CAN get a Canon tilt/shift lens for their 35mm and digital cameras.

thank you. i know how to use a view camera.. ;) take those same principles and apply them in "wrong" situation. it is very easy to get a n extremely selective focus that has nothing to do with depth of field. its a manipulation of the plane of focus.. It is often applied that way in the "fine art" world...

I realize now that you probably know more about view cameras than I do.

I'm having trouble understanding exactly what effect you want to achieve. I didn't think that lensbabies or ethereal glow actions matched what you said you wanted so I went in a different direction with my post. Maybe it would help to give an example something done with large format that you would like to duplicate with digital.
