    I have done some searching thru the forums, but cannot come up with the right word or combination to find the name of the software package.

    Scenario:

    Shoot a photograph of something using a tripod and manually set the DOF.
    Slightly change the DOF and shoot again, and again, and again.

    When finished, there is a software package that will merge the multiple images into one with clarity "front to back".

    Imagine - macro of an insect that is sharp from tip of antenna to end of tail; or a product shot of a ruler that is not shot from the top, but from the end at an angle.

    This isn't panorama stitching, but actual merging of the photos with the sharpest of each maintained.

    I'm sure I've seen it, but did not mark the thread.

    Thanks in advance for your help.

    Didn't know there was a software package for this but I have a friend who shoots studio products and this is one of his favorite tricks to extend DOF but I know he does it manually. I will be interested to see the results here.

    Just did a quick Google:

    Extend depth of field
    Capture all the photons you want; the universe will make more.

    I've done a few of these but they're very difficult to do. You have to have a wind free environment as the images need to be a near perfect alignment. Max Lyons provides an inexpensive version called TuFuse.

    Do a search of focus blending.

    Focus blending is possible with PhotoShop C4, though I haven't tried it.

    tufuse from Max Lyons works ok and has explanations, demo version with watermark can be downloaded

    Also, look for Helicon Focus. It's the main commercial product out there. There was an open source version but I'm not sure it's up-to-date.

    Wouldn't this be the same thing as focus stacking? I know a lot of macro photographers use a program from this source. I have never used it so don't take this site as a recommendation.

    Steve,

    That's the CombinZ website. It's what I was thinking about when I suggested open-source. The person behind it is no longer supporting it and it hasn't been updated since 2008, as far as I can tell. I was on the mailing list for a while but I could never get a handle on it.

    That doesn't mean the OP shouldn't try it, it might still be of interest.
