Slugs like mushrooms #slugs#mushrooms

Brown slug, roughly 3-4 inches (8-10 cm) long, with black tentacles and orange skirt is stretched across 3 mushrooms (best guess: Gem-Studded Puffballs), with the 3 mushrooms having clear signs of being partially eaten.

Cinnamon moved when he noticed me, so this is the only picture I got.

Cinnamon, a brown and white Mini Aussie is looking at Ahsoka's white, fluffy kitten paw reaching under a door at him.

Still obsessed with converting some of my focus stacks into black and white drawing-like pictures. Here's a new one:

Two laptop keyboard screws, each about 1 mm in height and width. The one on the right side of the picture is oriented heads up, with the phillips screw slot visible, the one on the left is resting on it side, with the threads of the screw visible. The picture is a composite image made from a large focus stack rendered in black and white and everything not sharp made transparent.

I personally would go for the first one, but I wear my WHM “Night Vision” and “Monkey Pizza” shirts to work.

One more:

A microscope photo of three stamen from an Herb Robert flower. They have a dark red anther and a translucent filament. Each anther has various amounts of yellow pollen attached to them. A few pollen grains have been knocked off. This is a combined image, a focus stack of 15 images to put more of the subject in focus.

A few pollen grains have been knocked off. This is a combined image, 15 images at different focus depths have been converted to black and white and combined to make an image that somewhat looks like a black and white drawing.

Here's the script. It's probably useless to most people. github.com/davebob3/gim...

Today's obsession: reworking old photo focus stack into black and white images that look vaguely like a drawing. Resurrected a 12 year-old GIMP script to do it. #microscopy#focusstack#GIMP

Highly magnified tip of a duckweed root, roughly 40X but cropped. You can see some cellular structure here, but not a lot of detail. This is a combined image, a focus stack of 12 images to get more of the subject in focus. A few diatoms have attached themselves near the tip of the root.

This is a combined image, the 12 images were converted to black and white to remove low contrast areas and combined to make it look something like a black and white drawn image. A few diatoms have attached themselves near the tip of the root.
A microscopic radiolarian shell from a prepared slide. The edges of the crystalline shell are dark, revealing the structure of the shell. The shell has a pointed tip, with three connected spherical structures with holes, increasing in size from the tip. The end has three fin shaped spikes. This is a combined image, a focus stack of 14 images to get more of the subject in focus.

I originally went out to photograph a spider and web backlit by the afternoon sun, but it was too windy, these petunias are the consolation picture.

Three petunia flowers in a horizontal row. The flowers are yellow with white at the end of the petals.

More #ciliates, currently unidentified...

A mostly transparent oval shaped ciliate with a diatom and round green algae clearly visible inside it. This image is roughly a 200X microscopic photo.
A mostly transparent oval shaped ciliate in focus above some out of focus brown debris. This is a microscope picture at roughly 100X.

This speedy ciliate was tough to get any decent pictures of, and I'm not sure these qualify... Most likely Spirostomum ambiguum

A long, thin Ciliate with a round front and a blunt end (Probably Spirostomum ambiguum).
