I love the way the wider headstock looks with its higher peak, but the break angle at the nut for the D and G strings may cause some binding/tuning problems.

While I know that there are differences in headstock shape/profile, I believe that you are drawing the wrong conclusions from these two photos.

The way people make photos these days (usually with an iPhone or similar device) it's not really possible to do accurate research.

Gathering photos from the internet only gets you that far and there's nothing like holding instruments in your hands and look at the actual details.

I took 2 quick shots with my girlfriend's iPhone ( yes ......... I don't have one myself) and I did what a lot of people do:

And yes, you're looking at photos of the same headstock!

So, it's an optical illusion! I'm not a photographer so I had no idea. Thanks Hans!

That is an amazing yet simple demonstration. Thank you for the focal point, Hans.

No, I don't think you should call this an optical illusion; I believe this would be called lens distortion, but maybe that's not the right term either!

Edit: Maybe perspective distortion?

I think lens distortion rather than perspective. It would be interesting to take the same two pictures with an SLR with a standard lens (usually 50mm) and see if they look the same. I may give it a try later.

Never the less, it's more than the eye can't see.

I would say it is perspective dependent. But let's also cosider lens angle and what follows thereof. I study the case of taking the picture from an angle - not straight.

Hans used iPhone - having one I know that it has wide-angle lens - thus you can/must come quite close to headstock to get a picture that fills the screen. Therefore the relative distance between closet and futhest point can be 2x. When you use narrow lens angle - you must back off to make object fit on screen - from that follows that the distance difference from same angle will be reduced relatively.

To demonstrate - I took two pictures of the same 2G memory chip - one from close distance - one from further out - same angle - then I zoomed them to be about same size on my screen and took a screenshot.

At quick look one might think that picture on left was taken more from upright - but they both are about the same angle - right is a close-up - left is from distance and zoomed in.
