Wow, the darkness works so well in this, and that last light is looking very fine indeed. Shame there isnt more colour in those clouds.

I really like this, and it's from 3 shots stitched together? It's perfect, seamless. I'm intrigued by shift/tilt lenses too, did you have much shift happening for this shot?

good question, to go one further, for a scene like this is there really any significant advantage in use a tilt/shift?

...... One exposure in the middle, use the shift all the way to the left, then all the way to the right, and stitched in PSCS3....... just remember to have your camera set to manual and take all your readings before using the shift controls......

....... more control of DOF using tilt, and a much bigger image as you are using 3 frames stitched and no distortion

yep I get that, but what are the advantages of using this for this particular scene where a, for example, 50mm lens could be used with almost no distortion also.

not having a dig here just trying to understand and could be my lack of knowledge :up:

....... yes you could use a 50mm lens, and a guess would be around 6-8 images would be needed to get the area in, as I am using a 24mm

advantage of the tilt gives much greater control over the DOF...... and an area like I have covered would be sharp from the front to the back around f8....... which you cannot do with the 50mm.....

bit like using a 5x4 view camera...... square everything up, focus, and tilt the front of the camera forward to increase the DOF..... same principle using a shift lens, or perspective control lens......

right, heres how i see it,

using the shift/tilt lens in this particular case gives 3 advantages over a normal lens (whether it be a 50mm or 24mm):

1) Maintains the optical centre of the image, this prevents parrallex error with teh foreground and removes the requirement for a pano head.

2) maintains the rectilinear perspective of the image - this I can see as being a real benefit.

3) less images needed to achieve the pano when compared to a lens of teh same focal length.
