Site that shows effect of different lenses on portraits

There was a site someone posted before that shows a model shot with lenses from wide to telephoto, and how it changed her look.

If someone knows what I am talking about, can you re-post it?

Thanks

nobody?

If there were such a site, it would be grossly misleading. Any difference in perspective would be due to differences in distance from the camera to the model, and completely independent of focal length.

Possibly so, but it is not misleading in the fact that the pictures were all framed the same, and showed drastic differences is the way the model looked from wide to tele.
The point was to show the difference focal lengths make when shooting a particular subject, in this case a headshot of a model.
Thanks

Don't say I never gave you anything.

The key thing is that focal length has nothing to do with perspective, but all the shots in the link above have the same framing. They are shot at different distances (i.e. different perspectives), and focal lengths are changed in order to achieve the equivalent framing of the headshot.

So really what the site is showing is the effect of different perspectives (i.e. different distances) on portraits, not the effect of different lenses.

Focal Length + Framing = Perspective

If the Focal Length is the variable, and Framing is the constant, then Perspective changes. Your link is a good example of this.

I remember recently looking at a PDF that I think was made by Canon showing the same phenomenon with a woman standing next to a bridge in front of some buildings (I think). Can't remember where I found the link though....

I think that is what most people are looking for.....same framing, different focal length, hence different distances and different perspective.

I seriously doubt anyone cares to see the difference between taking a head shot from 5 feet away with a 50mm, and 5 feet away with a 300mm.

I consider the focal length doesn't make a difference argument, without taking it in context of real life shooting, more as trivia than anything really usefull to know.

That's all very well until confusion ensues over such spurious notions as "wide angle distortion", "telephoto compression", and "foot zooming". Understanding that perspective is caused by distance alone makes these ideas immediately suspect, as they should be; holding the opinion that perspective is influenced in any way at all by focal length, no matter how pragmatic that may seem, allows such nonsense to flourish to the detriment of the unwary.

Touche.

Several of us are working an a very comprehensive article about perspective with absolute proof that focal length, in itself, has nothing to do with perspective in an image. I'm taking the rest of the week off, so I should be able to get my part launched by the weekend. The rest is waiting for my part. We hope that it will be educational for the group.

KISS or nobody, who needs to understand this stuff, will understand it. Looking forward to seeing the results of all your efforts.

That's the one, you da man!
I suppose, lens perspectives and distortion, though is that not a product of using a different lens to take the same picture? either way, thanks!

The only way to take the same picture with a different focal length lens is to crop the image captured using the wider lens to match the image captured using the longer. As soon as you change distance in an attempt to match subject size for different focal lengths, you also change the perspective, affecting both the geometric rendering of any main subject and the relationship between foreground and background; the pictures could not then be considered the same.

I got cha, the reason why I was looking for it was to showsomeone how using a longer lens could minimize a big nose.
