Well, I am just concerned his settings might be off for landscape captures.
Thanks Lou. Jim Kasson recommends to use the Electronic Shutter (ES) on a tripod. Then there is no delay necessary between shots. So the last parameter is 0. The second parameter set to 1 gives the smallest increments to focus distance. The first parameter set very large like to 99 or 100 tries to make sure that the focus bracketing series is not cut off prematurely.
In in my experience with my 50S there is no foolproof way with the current firmware. Depending on the scene, it either works, or one gets too many shots, or just one shot.
Too many shots is not a problem, simply increase the second parameter until one gets close to the total number of shots desired. I typically would not decrease the total number of shots allowed so that the series doesn’t get cut off before focus can reach infinity. As Lloyd observed it’s probably a good idea to add an infinity focus shot just to make sure one has one.
As Jim Kasson has explained, the focus distance increase is chosen by the camera such that the Circle of Confusion (CoC) is constant across all the images of a series.
I find most frustrating if I only get one image although the camera is set to focus bracketing. That typically happens when the first shot is focused pretty far away, for example I am standing at a cliff edge and there is no foreground to focus on. My assumption is that in that case I am not getting a second shot due to the CoC algorithm cutting off the sequence as it determines one is already close to or at infinity. In that case trying to find some foreground subject, however contrived, to focus the first shot on might help. [FONT="]Or add an infinity focus shot manually.[/FONT]
Practice makes perfect. Good look to you.
Once you have a focus bracketing series, then the real fun begins namely to stack the images without artifacts or blemishes. :grin:
