Marine diatoms attached to Polysiphonia

Post by Charles Krebs »

Going through some photos from a month or two ago, I came across this arrangement of diatoms found in a salt water sample.

Hi Charlie--

Very, very nice. Its hard to get the fans of diatoms all in focus, let alone the getting diatoms and their substrate rendered well together. I've found hydroids whose stems were encrusted with diatoms but I haven't been able to get good pictures of them, nothing close to a shot like this. I'm curious to know what optics you used and where you collected the sample?

David... there were collected in West Seattle, on some rocks on the public boat ramp on Alki Point. It was DIC with an Olympus 10/0.40 D Apo. It was made with Helicon Focus and a relatively small "stack" of 10 images. I set up, and looked at, quite a few specimens before I had one that was nicely arranged for photographs!
