After reading the adjacent thread 'auto bracketing in manual --D90' I searched tutorials for information on compliling and either missed the info or it is not there
My background is with Panoramas and since I have rarely used a tripod for them I am puzzled by the other thread OP's concern about touching the camera becuase as with a pano I would hope the separate files are organised as layers prior to compilation. If this is what happens I would expect a slightly out of alinement file/layer to be easilly registered with the others. I adjust the density of the layer I am registering to perhaps 50% to aid this process and the 'correction' needed with a pano is much more than a slightly nudged bracket frame.
An alternative approach would be a tethered set-up with shutter speed controlled from the computer? Perhaps not practicable in the field.
