That is true but isn't each line fixed/done after one pass? Meaning that even if there are movements in the landscape this will only affect the next row that will be scanned.

What I understand from multishot backs is that they will generated the final image after having made the 4 (or 16) shots. This would impose a bigger problem when the images are not perfectly aligned.

yes, absolutely, but each line will/can therefore be moved, from one step to the next, producing weird results because not "corresponding" to or being in line with the preceeding lines. With a multishot the result when moving is a bit different, the 3 RGB colors in their whole do not align exacly anymore in the whole image (in the places it moves). The result/effect is certainly different, but both scaning and multishot need absolutely still subjects.

Allright than we agree on this.

I believe the difference is that with the scanning back the results can be very pleasing. I have seen images of coastal lines where the waves became truly magnificently surreal as well as other moving stuff like trees in the wind. Naturally this will not apply for everything. I will try to find the images I am talking about and post the URL as soon as I did.

I believe the results of movement for multi-shots will be quite horrific when movement comes into play unless you are in for colors going completely insane and blur in unsuspected places.

Right!

Would be interested to see such effects on waves, although I have tried it out during the times of the Dicomed scanback in the Swiss montains, with clouds (and - 10ish).

Just for the record - I was not advocating multi-shot or scanning backs as the ideal landscape solution, of course....

Single shots are the obvious preference in that environment.

~humbug... just wading through tons of URL's to get to these images but no luck sofar. I will continue to look if anybody else knows what I am talking about (this does sound kind of silly) please don't hesitate to help out.

Otherwise I might put it on my to test list smile.gif

Naturally we did not take that as an advice Steve. Single shot is a lot less hassle but scanning (maybe multi as well though I really doubt that) might give you a lot of fun and unsuspected results (some even really nice).

I still would like to have multi shot for in my studio but than again I invest like crazy but for some reason my wishlist appears to be growing only sad.gif

If you shoot a single shot and a multishot you could piece them together and if there are any movements e.g around a few leaves etc you could leave them.

think of the multishot images like of the layers in a negative...or cmyk printing plates...if they don't line up....not pretty
a scanning back does just that it scans the image top to bottom and movement will simply be blurred, like a long exposure....

the effect of movement or ( even little ) variations of lumince result in a chessboard-like pattern, which is not very pleasing. a scanback expose line after line so a slight change in exposure ad example has not a dramatic impact on the image, except that it becomes a little bit darker at the bottom than at the top or the opposite,- but its still a coherent image. not so the 16shot cause the shots are added on a pixel per pixel pattern.
