Nikon CF N Plan Achro 4/0.13, 40 images stacked in HF


This is the head (a little over 3mm between antennae tips) of Agapostemon texanus, a fairly common halictid bee here. The purple background is a transilluminated petal of the passionflower upon which it was feeding when I captured it. The image suffers a little from stacking artifacts - I'm still working on that aspect Confused

Looks pretty good from here! Very Happy

What sorts of artifacts are bothering you?

Thanks Rik -

I was able to remove a lot of halos around the perimeter of the head with PS, but can't address the internal ones very well. I think they contribute to an overall loss of resolution; e.g., I can see see clear branching of the setae in the individual image slices, but lose a lot of this detail in the stacked image.

I find enjoyable image, perhaps find fault is higher background brightness antennas, antennas for better lighting would have better balanced final result, are only subtleties, image and beautiful!!

Thanks Antonio,

I agree - the backround does compete with the head. The image would have been improved if it had received about 1 stop less light, either by moving the backlight farther away, or masking it with a neutral gensity gel.

I wonder if you've tried TuFuse? Sometimes it has less trouble with halo than HF does.

The subject itself is nicely shot but I'm not sure about the colour of the background. It seems to clash with the green/blue of the head rather than complement it.

Technically nice capture but somehow I don't like the entirely disembodied head look. Was the head actually detached? Stack looks fine to me at this size!

I agree Rik - TuFuse looks very attractive. However I doubt a version will be developed to run on a Mac. I either need to upgrade my Power Mac G5 to an Intel version so that I can run Windows on Parallels or BootCamp, or buy a machine that runs Windows native.

You're right P_T, the idea was more attractive than the outcome.

Thanks Laurie. The detached head is a bit disconcerting; it brings to mind scenes from the French Revolution. The head accidentally became separated when I was attempting to position the bee in front of the lens, so I thought I would photograph it independently to see how it looked. This particular bee is so beautiful I think I'm going to make more attempts with another specimen.
