Is there a nice name for the line in this figure?

Help!

I am trying to write an article about photography tips.
In the following figure, there is a line (the horizon) cutting across the model's neck (it is a common mistake in photography).

Is there a nice term to call this line?
I can come up with something like "head-cutting horizon line" ....

thanks

There is a horizontal line across the model's neck

or

(what I think you mean)

The line of the horizon coincides with the neck of the model

(making the head appear above ground and the rest of the body below - the eye continues along the horizon and 'through' the neck)

That sounds rather Germanic! ;-) Generally, a clump of nouns like this is a bad idea. As Dave suggests, you need to say what the horizon does - something like 'in your pictures, make sure the horizon doesn't cut off the model's head', or you could use a participle: 'In this picture, the model appears to be beheaded by the horizon.'

Or if you wanted something snappier, what about 'unintentional dissection'.

"unintentional dissection" sounds like the term I am looking for. So, I guess I can phrase the title of my academic paper like

"Automatic detection of unintentional dissection line in environmental portrait photos".

Any suggestion will be highly appreciated!
