Even when comparing 400mm @ f/5.6 to 200mm @ f/2.8 ?

That would work.  Just give your subject a walkie-talkie so you can tell him/her when to smile.

LOL that's so true. Especially when taking a full body pic of an adult. You're getting a pretty unique "compressed" look, but the lighting should be also appropriate otherwise people's faces start looking weird.

Mind you I hate the term compression when people really mean perspective, but that's another thread.......

I mean what I mean ;)  https://en.wikipedia.org/wiki/Perspective_distortion_(photography)
"Perspective distortion takes two forms: extension distortion and compression distortion". Has nothing to do with the lens but the distance to the subject.

You might well mean what you mean, but using that article as any kind of authoritative confirmation is ludicrous. The author makes some good points but I disagree with the terminology which has no citations or confirming notes and the wording is ambiguous or plain wrong in places.

It isn't just the distance to the subject, it is the relationship between the differences between the position of the photographer and the various items within the image.

Besides, I wasn't referring to you about using compression because you had the good sense to cover it's use with quotation marks, I meant the guy in the video and various other educators who clearly never had any kind of formal education in photography and just repeat, parrot fashion, expressions they hear.

Ahhhh... Yeah, the guy in the video should have used "finger quotes" and then we wouldn't be nit-picking.
I can't list my gear. I'm too ashamed. Everything I have is crippled and obsolete.

LOL. But nitpicking generates 95% comments on this forum BTW.

Technically, I think it's closer to 96.5%.  Also, you should have placed a comma after the word 'forum' in your post.

It looks like our next nitpicking war is going to be around this topic: https://en.wikipedia.org/wiki/Sentence_spacing  :)

Before discussing acceptable options regarding moving from one sentence to the next, I believe we should discuss the proper way to end the first sentence: https://en.wikipedia.org/wiki/Full_stop:D

From the Wikipedia article on Murphy's Law:

Hartman's law of prescriptivist retaliation: "Any article or statement about correct grammar, punctuation, or spelling is bound to contain at least one eror." Named after journalist Jed Hartman.

It's an example of Muphry's Law (https://en.wikipedia.org/wiki/Muphry's_law).
