Re: DIC versus other forms of Microscopy

The Sanderson picture of onion skin is spectacular and I remember reading the paper now - can't remember why I didn't try it. The paper itself does not show good pictures, but the onion skin photos by Saul was amazing for sure.

Re: Conjugating Mougeotia viridis - filamentous algae

Interesting photos. I sometimes find desmids when squeezing moss next to a lake, but never seen the structures you show - very nice images.

Re: What is this?

HI - as Pau said it is a Diatom - you will find them as slime on rocks in rivers, streams, waterfalls and ponds and there are thousands of shapes and different species. What caught my eye was your Olympus E microscope. That was my first "real" microscope I purchased over 50 years ago and I am still ...

Re: My first crystallisation Caffeine

Hi Nice images of caffeine they mostly show those pointy needle like-crystals in water in my experience. Two suggestions to get other shaped crystals. 1. Melt the crystals on medium to low heat on the slide with a coverslip on top and they will form crystal sheets with more variability you can also ...

Re: Euglenoids

Very nice photos - I tried getting some high mag images of Euglenoids a few weeks ago and it was difficult and I never achieved images I was happy with at 1000X they just kept on moving. I tried flattening them by removiing most of the water under the coverslip but still difficult. What did you do t...

Re: What you wanted see in Scanning Electron Microscope?

Beautiful photomicrographs, also visited your web site to look at some of your amazing insect photos. I am fortunate to have access to a SEM at the local University, but I must pay an hourly rate over $100\hr. Best prices for a small SEM I have found on a desktop models for Forensic science labs is ...

Re: DIC versus other forms of Microscopy

Hi Scarodactyl - I looked at some articles about Sanderson contrast technique sometime ago, but I wasn't that impressed with the images and ended up filing the paper somewhere. I am hoping that DIC and phase contrast will eventually be available to everyone by using software to process bright field ...

Re: DIC versus other forms of Microscopy

Hi Lou - I understand one can even make their own Fluorescence microscope, they still require dichroic filters etc and the cost of new Fluorescence attachment rrom China are in the order of $5,000 e.g. visit Motic.com web site - sometimes you can get lucky and get lower cost scopes or irridiate t0eh...

DIC versus other forms of Microscopy

I have just posted a new article on my website about DIC microscopy and how it compares to other microscopy methods. https://www.canadiannaturephotographer.com/diffential_interference_microscopy.html I have also been trying to find software previously described that simulates DIC and Phase contrast ...
