Surely that's just showing the cut through the leg in front?
If it was photoshopped I would think it would look perfect!

Of course I was referring to how the "cut" was made. Not the whole image..
;)
Personally I have nothing against post-processing..
It's just that I find the image a bit blurred in that region. That's why I
was
curious if the image is a result of two other images and PS:d together.

This is just a quick attempt at that illusion. It only works for an orthographic
camera. I've included another view so you can see how it's done :)

I meant it shows it's a cut in pov: You can see a light edge on the bottom part
of the cut, which suggests it's actually a 3D cut (the light bit being the
surface of the cut catching the light).

Though I realise now my first point was kind of dumb, 'cause like you say you
would also have a gap if you used photoshop! doh! :)

Hehe.. Of course it's enough.
If you really wanted to impress me you should have done it in Paint.. ;)

My point again was not to accuse you of cheating. I just wanted to know
where the artifacts came from.. that's all..

Cheers
