Yes, I remember your interest in micros. Thanks for the tip on combining
images in Photoshop. I can see how you do it, but it seems like a lot of
work! It seems that Helicon and other software can do all the work for you,
besides the ability to use multiple images. I read about similar software
that is used for astronomy, although the Helicon seems more powerful.
In Photoshop you could copy an entire image and paste it over the other one,
and then by hiding one at a time, select the parts that are in focus, and
selectively erase the parts out of focus. To make sure you do not delete
more than you should, you could make the top layer semi-transparent.
Regarding your equipment setup, Sid, it may be possible to zoom in (if your
scope allows) and record small parts of the image, then later combine them
in Photoshop or in a software used to make panoramic photos (or a composite
from several photos). Just remember to leave some overlap between photos, to
make the merging more precise. That way you could increase the resolution
from your video. You could also repeat the process for different focus, as
you described.
Here at the university we have a nice Olympus stereo (dissecting) microscope
and a good compound scope, and an Olympus DP-70 camera (12 mp), a great
setup. However we currently lack the focusing software discussed above, but
I will try to get it soon.
Simon, what is your photographic setup? Your photos are great!
Regards,
Fabio
