Crustaceans

This is the third post of mine that actually all form part of a larger project I am working on with my daughter - Life In A Drop Of Water. Idea is just that - go out and see what life forms you can find in a single drop of water. The previous posts included the cyanobacteria (fluorescence pictures) and the ostracod / mite set. It is great to be privileged enough to be able to show your kid these things at home. She freaked out whenever I did something fancy such as the polarization of the amphipod - she loved seeing all those colours and learning about polarized light etc.

Because the 4x/0.16 does not work with the universal condenser - I edited the black circular vignetting out but left a little.

I tried U-LC and U-ULC both neither works well, neither has a slot for QWP or LP so I returned both.

hello pwnell,

congratulations for your pictures (specially Nr. 3 and 4).

In this case you could use a low power condenser (I made good experiences with it).

As I mentioned above I tried Olympus' U-LC and U-ULC low power condensers designed specifically for the 4x and I could not see any difference between using those condensers vs. swinging out the TLD condenser in the universal condenser.

Besides - neither allows for any kind of lambda or quarter wave plates to be fitted, making above images impossible.

hello pwnell,

NikonUser wrots about his experience with the Olympus Low Power conderser in this posting:
http://www.photomacrography.net/forum/v ... +condenser
His experience was a positive one. (His posting was the reason that I bougth a Nikon low power condenser. This is a good possibility to say THANK YOU to NikonUser for sharing his experience).

Here are two photos with the 2x/0.08:

The first was taken with the TLO condenser swung out, the second with an expensive U-ULC condenser. I see virtually no difference, even at 100%.

Man, that copepod stack is a-maz-ing!
