Oh I was talking about the "willie lotts cottage". I didn't notice a wide pano shot. Not all the images load in my browser sometimes.
Sorry I meant Willie Lott's Cottage. I keep referring to it as the 'Hay Wain' as that was Constables most famous picture when he painted horses and cart ( Hay Wain ) in it.
The picture is a four frame panoramic with overlap, so effectively shot on a larger format than most DMF; it's 36 x 75 mm @ 60 mp, whereas say a Pentax 645D is (about) 30 x 44 mm @ 40mp. So it is a very wide angle shot but looks natural because of the way we have done it. To shoot this on a single frame with FF you would have to use a 20mm lens and crop out the top and bottom to give the 2x1 aspect ratio. I've attached it again so how it doesn't look like a 20mm shot.
By using the FF to create a larger format we gain nearly all the benefits of the MF; resolution, tonality, colour depth etc. I'm not sure if we gain in DR due to lower enlargement, I don't think we do.
The drawback is that it is a pain in the a**e to do compared with a single frame.
