Originally posted by interested_observer Another approach is to stitch adjacent (and overlapped) shots together. The technique works well and is free. You can use Microsoft ICE utility to do the stitching.
I like to do this, and the current software for it is very good at stitching. Still, follow some steps to get good results.
Decide what's in the frame. Choose an aperture that gives you enough depth of field, a shutter speed that freezes movement, and an exposure that covers enough of the light variation. It may be handy to take one shot of the brightest part of the composition, to make sure it's not overexposed, focused correctly, etc.
Then I like to turn off all the auto features. Turn off autofocus so the camera doesn't choose a new focus point for every shot. Use M mode to keep the exposure set to one value, or the AE-L button. If I were shooting JPGs I would set the white balance to one value, instead of using auto white balance. I shoot in RAW and set all the photos to the same white balance in processing.
Then all you have to do is overlap your shots. You can hold the camera vertically too, if the software is intelligent. Too many shots are way better than missing a spot. A fast computer is good for combining the shots.
