ledlyt - webcam photomicrography
There are a few general sins to confess here. The photos are strongly
biased towards small water inhabitants, since that is the business of
Microcosm Consulting, operated by Dr Barbara Bowles. I will put names
where I can, but I am no biologist. Some artwork treatment has been
used, but this has not extended to any form of 'painting' under
control of the mouse. All treatment has taken the form of
conventional manipulations such as brightness, hue and contrast, plus
a few Photoshop-style plug-ins I have personally written for pixel
analysis and image 'cleaning up' over the whole image area.
As regards the size of the cells shown, the anabaena circinalis
photograph has individual cells measuring at about ten microns in
diameter. Normal eye microscopy with full professional equipment can
just about resolve one micron. I would estimate from this the webcam
photo system is resolving to somewhere between 1.5 and 2 microns.
This is a colony inside a common outer membrane, which can just be
A large inhabitant at lower magnification. With a small sensor area,
being unable to reduce magnification enough to 'get it all in' is
quite common. Odd strings of a.circinalis in the background give the

No album is complete without spirogyra. This is one end, and it
