It was just a bit out of range.
'That' statue in Glasgow
Since it's pantomime season : "He's behind you"

An unusual panorama in that it was from two images that only slightly expanded the width, and the two were shot several feet apart. Stitched in Affinity Photo.

can you explain what you mean by this? compression usually refers to the use of a long lens compressing the background which (ironically) makes it larger.
this to me looks like a wide angle lens with the background shrinking.

That’s exactly what I meant. Look at how the buildings and and distance compress into a the vanishing point. Certainly a longer focal length. A wider lens would distort the foreground and cause the subject to tower over the scene. Instead, he’s being drawn in. I’m not saying it’s like a 300mm, but definitely on the longer side of normal.
Or I could be wrong.
Spot on. Lens is a Nikkor DX 16-80 @ 44mm on an aps-c so 66mm ff equiv.. what I would call a long normal
For the purposes of background compression, the 44mm length is still accurate, as all you have done is have the sensor crop out the edges of the photo. 44mm verges on the edge of wide angle, although closer to normal, of 50mm. Normal lenses show images like our eyeballs see. If he had used a telephoto lens, 85mm or longer, those buildings (the spire between the horses legs in particular) would be much larger, and compressed, or flattened towards the viewer. A wider angle would have minimized those background buildings even further.
Now, if you are used to shooting at 20, 24, or 35mm, I can see how you might think that squawk's image has some compression going on. But this image would have basically looked exactly the same in real life from his position.

(none of this is meant to minimize the quality of squawk's photo. ? just trying to educate and be educated as to terminology)

What is Lens Compression and How to Use It In Your Photos

I’m not sure what you mean by this. All longer focal lengths do is crop your field of view. It’s the same effect. A longer focal length does not give you the perspective of moving closer to the subject. A longer focal length and sensor crop factor are literally the same effect with regards to field of view.
Yes, if you stand in the same spot. This is talked about in the first set of images in the link I posted. ?
But if squawk had framed this image exactly the same way with a longer lens, he would have had to be standing in a different spot. At that point the optics of the focal length come into play, and the background starts to compress towards the viewer. It's because he used a wide to normal lens for this framing that the background looks the way it does. The statue is giant relative to the buildings (some of this is just perspective of being lower). Obviously in real life, that isn't how statues work. But just because the buildings recede to a vanishing point doesn't mean the background is compressed.
Here's another good explanation. ?

This is all very useful to remind myself that what I see in a photo is different from what others see.
I think we are all saying that perspective is governed by the distance from viewer to subject. All the focal length does is change field of view.

I promise I’m not trying to be argumentative or difficult, but I still don’t understand what you’re trying to say. I said the image looked compressed as if it was on the longer end of normal. Squawk7000 said it was 44mm on a crop sensor which is on the longer side of normal for APS-C where normal is closer to 35mm. What about my accurate understanding of focal length and compression causes you to believe I need an article for research?
i am going to be out for a while but i will make a new thread about this later for better discussion. we are getting far beyond the scope of the potd thread. ?
