For those who might be interested I have posted a batch of pictures at: http://personal.inet.fi/cool/don.williams/hold/micro
The subjects are bacteria and the scales from the wings of a very small moth. The wing scales show detail down to the limit of resolution of the light microscope at high magnification (about X1500). These scales are as good as diatoms for testing optical microscopes. There are phase contrast, dark field and bright field pictures taken with a 40X and 90X oil objective and immersed Aplanatic condenser. I am rather pleased with them. I did no bracketing, but did change the exposure factor to 2X and to 4X for one picture each -- this ruined them. All the others were taken with the ME Super set to automatic and the exposures were between 1/8 and 2 seconds. I used the shutter in the belief that mirror and shutter vibrations wouldn't matter with this massive frame and the long exposures - they didn't. Film was Fuji Superia 200 processed this morning in Tetenal Chemicals that are now very old indeed. Anyone wanting details of the pictures please contact me off list. Some picture series are taken at different focus heights and in some the detail is very fine.
