Cyanobacteria - Oscillatoria

[hkv]

60X Water Immersion. Single Image (!) no stacking. It is interesting how resolution seems to improve when you manage to capture a single image in focus rather than introducing stacking artefacts/noise. Rarely happens though with cyanobacteria as they tend to wiggle all over the place.



Cropped version and slightly rotated:

Bonjour.
Superbes images.
Car ce ne pas facile à photographier comme spécimen et en plus ils bougent touts le temps.
Car j'en est photographier la dernière fois.
Merci pour le partage.
Cordialement seb

Very nice!

Superb.

I agree with you about single images well focused.

Are the backgrounds in your photos cleaned up - or do you have nice clear samples?

I applied a slight gaussian filter to the background. The remains of the debris in the picture can be seen in the lower parts. The upper parts only had small specks and disappeared in the gaussian blur filtering. My experience is that when using 60X and 100X the backgrounds are often clean and nice because you are so zoomed in. Also, the depth of field is so small that debris outside the focal plane disappear. At lower magnification you get everything in focus and the backgrounds gets worse.

Very good images.
