Pennate diatom, 60X DIC, 100X darkfield

Post by Charles Krebs »

After taking a few DIC shots of these diatoms with the 60X, I thought I would try some high magnification darkfield with the 100X. Usually a pain and messy with the oil. And frustrating with live diatoms because at these magnifications they seem to move realatively quickly. But I think it gave a much nicer rendition and "feel" for the the glass-like clear silica frustule.

Beautiful at 100x. How deep did you stack these? I've never bothered to try such high mag imaging on these because they positively zoom along as you say, and I don't have flash set up yet. But you've inspired me to get a move on and do so :)

Beatsy,
How deep did you stack these?
Only 6 images in each of the 100X stacks. These were done without flash... using the "stock" 100W halogen lamphouse. Typically I keep an eye on a few really nice looking diatoms as the water evaporates from under the cover-slip. Then just as soon as the slip drops down enough that they get "stuck", I shoot the frames I need as quickly as possible before they frustule cracks from cover-glass pressure.

Doh! I never thought of that. I usually run a thin bead of vaseline around my cover slips to prevent evaporation. Surprising how long things keep going too. Thanks for the tip.[/quote]
