    Anybody doing focus stacking?

    I am curious about how well it really works.

    Thanks,

    Thanks,
    We did a workshop a few months back where we used Helicon Focus. It worked really well.

    I see if I can get Doug to put up some of the sample shots.

    Re: Anybody doing focus stacking?

    I have posted a couple using focus stacking. Of course it is very sensitive to subject motion; grape leaves waving in the air or the moon moving, for example, but it is still pretty useful.
    I tried both with Helicon Focus and with CS4 align. CS4 is a little more direct since it makes masks that are readily apparent, whereas with Helicon focus, you have to first select that the masks be made visible, then edit them in a different program (I used PS). Helicon's masks are more like relative weight files, rather than masks, so I found it more work to edit those to eliminate subject motion. I only used 3-4 slices, perhaps more are necessary to achieve maximum benefit.

    I just tried the version in CS4 and it didn't work very well, so DL'd Helicon and must say it's pretty impressive. Here are two examples. Three images, one per bottle, quickly captured with simple lighting using my P45+ with 150 lens at f5.6. First one is the Helicon auto blend and the second is the front bottle frame.

    In astro-imaging a program that is commonly used is Registax or ImagesPlus .

    I have used it a couple of times to stack 15 or 20 shots but I know that people have done it with hundreds of shots with excellent output.

    This is an example of 8x5 minute subs stacked using a Canon XS (couldn't find an Oly one quickly) taken by Mike. B. from cloudynights forum.

    The signal/noise ratio is excellent on astro shots.
