I have never heard telesmash outside of railroad photography circles. I would think it would apply more to a larger depth of field than a narrow one, so the items in the picture appear closer together. Sports photographers tend to use very narrow depth of field to give the subject pop from the background. Nothing looks lamer than bunch of football players all mushed together when they are 10 or more yards apart-or the crowd looking like it is inches away from a play.

One of my pet peeves in rr photography is the f11 shot of a train melting into a background, but that's just me.

Telesmash has nothing to do with the depth of field. Shallow or narrow, zoomed in at 400mm, the objects in the image will still look closer together than reality. And I really doubt Ron did any cloning to make that shot look the way it does. It's pretty obvious to me that the zoom range he was working with created the illusion of the the train being close to the corn. I'm willing to bet there's at least a 20-30 ft gap of no corn where the rails lay.

And while this isn't exactly a telesmash, (ie: long zoom shot), the barn was actually a good 50 feet away from the edge of the corn rows:



Also, can you show some examples of f11 railroad images where the train is melding into the background?

Jim;
Since I wouldn't call depth of field an optical illusion, is it safe to say that telesmash is basically another name for optical illusion? or perhaps defining a particular type of optical illusion, like this site points out?

No, I'd call the telesmash and optical illusion, as you can have different DOFs with the same telesmash simply by changing the fstop. A 400mm shot at f2.8 is going to have a different DOF from a 400mm shot at f22. However, the telesmash illusion is going to remain the same. Telesmash to me is just a simple slang word for Telephoto Perspective Compression, Perspective Distortion or Flattening.

Here's a simple example of a telesmash. As the length of the lens increases, the subjects appear closer together: http://www.film-and-video.com/dofmyth.htm

Here's a wiki entry. The water bottles show the telesmash, or perspective distortion, perfectly: http://en.wikipedia.org/wiki/Perspec...photography%29

Telemeshing will amplify normal rail irregularities, and make steep grades look even steeper when shot head on.
