Default optical illusion

This shot should get a PC optical illusion of the year, must of have been at just the right angle, looks like it's plowing though the middle of the corn field, unless they are

Wow. Zooming in at the front, it literally looks like it's plowing the field down.

I did the same and see that too, right below the ditchlight box, the uncoupling lever either has blades of corn leaves around it, or there's a bit of cloning present.

No matter; for me, still a good shot. I favorited it

What kind of corn crop do you get out of ballast? Because it looks like the planted some there, too, right between the rails.

A telesmash will certainly give that illusion.

telesmash......hmmmm..better google that,.....what do I get? An old post from RP from Jim Thias
"Yes, but it's a telesmash. The train looks to be at least an eigth to quarter of a mile away,..................................
(and it had a misspelled word too)

So can you elaborate on telesmash

Telephoto lenses tend to make the distance between nearby and farther objects appear to be much less than it actually is. Hence it smashes the objects in the scene, giving the image a flatter appearance. For example, you might see a nose-on telesmash of a train passing a signal and you might think that the nose has just passed the signal, but then you carefully count the bits of the freight cars you can see and it turns out the nose is 20 car lengths past the signal.

Smash = flatten

El, none of the bird shots are examples of telesmashes, in my view. They are tele shots but nothing is smashed. They do serve as examples of shallow depth of field, which is a different thing.

They are all produced using the same camera method.

My point including them is that telesmashing has nothing to do with the subject, or what the photographer does with the camera, rather, it is how the image is perceived by the viewer.

True telesmashing will manifest itself if there is a large range of items, or subjects between the photographer and the focus point, or behind the focus point.

Otherwise, the background results in a Bokeh effect.

This effect can also be obtained using a short focal length lens such as:

Wel, to me a telesmash must have something smashed, specifically meaning made to appear closer together than they actually are, otherwise it is a tele shot but not telesmashed. I guess we just disagree on the usage of the term.

I agree. To me, telesmashes occur when the nearer objects and the background are all in focus and therefore you have trouble telling how near or far away things are from the camera, so everything in the picture tends to appear on the same plane. When the background is out of focus, making the subject stand out, the varying depths of different objects are easy to establish, hence no telesmash. But that's just me.....

That would be one way to define it, you would use a high f-stop to keep more of the image in focus, while a low f-stop would result in the fore, and back ground being out of focus such as the conductor shot.

Interestingly, when I look for "telesmash photography" in Google, no definition-containing page shows up, and the first four links are to train stuff. I guess the term is in use by railfans but not so much by photographers generally; I had no idea.

Well, thanks for all the info J & EL, I was kinda surprised too when I googled it and didn't get much, I started thinking it was a Jimism or something

I was under the impression that "tele(s)mash" referred specifically to the foreshortened appearance of a train seen head-on (or nearly so) through a telephoto lens, hence the reason it isn't used outside railroad photography.

Here's a good example of a telesmash. 400mm (well, 640 with the crop):

The signal is at least an 1/8th of a mile away from the lead loco, and the curving hoppers are at least a half to three quarters of a mile away.

Ok, this is actually a better example. The distance between the worker and the signal is well over a half mile. And look at that track...

Well, I was too hard on myself, I had *incomplete* knowledge!

And I do think that most railfans, and most on this thread, agree with my definition, so I am part of a shared ignorance! Or rather, a shared shared particularity in the use of this word.

Going through my RP stuff, I realize that I don't do telesmashes. This is as close as I could get, certainly not compression of a half mile, and I did it way back when. Don't go out to 200mm much anymore.

Oh, foiund another, waaay old also, not a really strong foreground/background thing but does exaggerate the grade rising to this point:
