Nice image, nice layout too. Did you move them around to get this? :D

Also, they remind me of chocolates...

Thank you :D This was an old prepared slide I found, I have no idea how whoever put this together managed to do it - incredible piece of work. It says "Diatoms - Exhibition slide" on the slide, so maybe it was to show off the skill of the person who made it?

I just had an image of you looking through a microscope pushing these around with a pinpoint :D

On that thought, do you have an indication of the scale of what we're seeing here?

I just picked the slide up to have a look by eye. You can just see something dead centre of the cover glass - it is about half the diameter of a pin head, so about half a millimetre across. So the whole bunch of diatoms have been assembled in an area with that diameter! It's incredible workmanship.

I colour balanced the previous image to get rid of the brown hue from the back illuminating tungsten bulb:

Very interesting!

Have you tried to photograph CD's, DVD's and BluRay discs? Would be interesting to see the difference assuming you can get to high enough magnifications. :)

I like the 1st one better. It has an aged look to it.
