laser microscope with a water lens

Hello, Photography Friends! I thought you all might appreciate this experiment the kids and I did this week- I think is really out of this world! Actually, it is in this world- in the microscopic world.

We looked at microbes in a drop of pond water, by projecting a laser pointer through the drop, and projecting the image on to a wall. Some information I found says this technique magnifies the microbes 1000 times!

The water drop acts as a lens, converging the shadows of the backlit microbes into a moving image. Depth of field seems shallow though- we found it difficult to get most microbes in focus enough to see a basic shape.

Any ideas on how to improve this?

Anyway, please enjoy the video!

Brown Canyon Ranch was recently made more accessible, thanks to a new road. I hope to get out there more often...

The families who occupied Brown Canyon Ranch over the years ranched cattle for nearby Ft Huachuca, providing food for the soldiers.

Good luck will rub off on you if you spy something lucky in this image...

It's lovely to see green this time of year! I am uncertain if the green here was the comeback of preventative backburning frm the Monument Fire, or just simply from moisture of monsoon rains alone.

I exposed a little longer than the meter told me to, to try to get more detail from the shadows in the structures. I'm not sure how much I achieved that, but I am happy with the exposure overall.

Daughter and I had a very nice and quiet outing to Brown Canyon Ranch last weekend. This is an outbuilding immediately off the house, which was built in 1905-07.

The families who occupied this homestead over the years ranched cattle for nearby Ft Huachuca, providing food for the soldiers.

The ranch house is currently undergoing renovation, hence the modern-day ladder perched against the building.

Monument Fire Recovery- ipomea longifolia, Coronado National Monument, Palominas, Arizona

Monument Fire Recovery- ipomea longifolia, Coronado National Monument, Palominas, Arizona

Canon EOS t2i DSLR with Sigma 10-20mm lens

Many of the Monument fire burned areas are starting to get green as our summer monsoon season drops much-needed rain.. (-:

Here is an example of one area. While driving in the Coronado National Monument, we noticed these beautiful, crawling flowers in the burn recovery area. They are a type of morning glory native to southern Arizona and northern and central Mexico. They are called a pink throated morning glory, or ipomea longifolia.

The US Dept of Agriculture classifies my new favorite wildflower as a "prohibitive noxious weed". Haramuph.

The flower opens up in the evenings, It was very thunderbumpy while we were there.
