Sunday Grab Bag

I am experimenting a little with noise reduction software. The first four have it and the rest don't. Please let me know what you think of the difference.

An aphid thrip (thank you anonymous commenter) at 60 and 200x. I found it in the flower of an early-blooming mangolia.

A dandelion seed from both ends at 60x

The tip of a zinc screw at 60x

Another fly from another spider web. Below, its proboscis and compound eye, all three at 200x.

The noise reduction has a slight impact on your grabs, but not a huge one. I would stick with it if it doesnt take a lot more time. By the Way I like Your Blog!

I am seeing them--you've been boingboinged. Anyway, this brings back fond memories of my dad and I taking photographs of mosquito larvae between two slides and mere drop of water for the critter under a dimestore microscope. We also used some crazy cool film that only showed black or white --I think it was lithographic or ortho--in any case it was the coolest stuff ever. I like yer stuff. Keep the neato pics coming.

Hi dedra,

I actually have a picture of a dried bloodworm which is a mosquito larva I've been saving for some future date. I used them as an occasional fish treat when I used to have a betta. I'll put it up on Monday for you.

Re noise reduction. The photos using it show things more sharply, including fuzz spots. Kind of like Unsharp Mask (why is it called that?) in Photoshop. I personally have a slight preference for the unmodified photos.

like: 1
dislike: 1
don't care much: 2, the same 2

Use it, don't use it, but post more pictures either way! They're wonderful. Do you take requests?

Yes, I take requests. Several people have made them in the other comment thread. The software I am using to denoise is called Noiseware Community Edition, chosen because, well, it's free and I'm poor.

Anyway, feel free to make a request. I make no promises though because sometimes something I think will look neat under the microscope looks really uninteresting (don't get me started on egg shells)...
