Today’s EPOD is the 3-D microscopy version of the Cabbage White Butterfly Eggs photographed by yours truly and turned into a stunning 3-D image by Dr. Brian May.

Brian made a suggestion as to how you could get an apparent baseline under a microscope to be able to make a stereograph – and as you can see the technique worked!!

I am now able to make 3-D images of anything I photograph through the microscope.  In addition of course, each of the 2 images is also a stacked focus-stacked image using Helicon Focus in order to get the depth of field.

Check out tomorrow’s EPOD :)

In order to keep my hand in the HSF world, I will be making a batch of high-speed flash units that will be available early 2016.

Talking to a number of professional users I have decided that the specification for the new batch of units will be:

  1.  Light output power 75 Joules.
  2. Light pulse duration 25-microseconds (1/40,000th of a second).
  • Recharge time less than 5 seconds.

The units will be powered by a 12V dry battery pack (supplied with charger unit).  Estimated cost of a flash unit, battery pack and charger is £2,000 plus VAT at 20%, plus p&p.

Let me know if you have an interest in this equipment.

Once again the missus’ superior eyesight found something interesting in the garden to macro.

This is apparently a Candy Striped spider, fairly common throughout England – but we’ve never seen one before.

Looks like a damn Aussie red back to me :)

I sent the guys at Southampton University the stl file for a Sierpinski tetrahedron (from George W. Hart) and they kindly printed it out for me.

Here it is below with the supporting base and supporting pillars still in place.

I liked the look of the focus-stacked photomicrograph of the Cabbage White butterfly eggs so much that I decided to take a 3D version this morning.

And here it is:

Today’s Earth Science Picture of the Day (EPOD) is the large DSS2 data mosaic I put together of the Tulip nebula region in Cygnus.

DSS2 data was downloaded (red and blue channels) and Noel Carboni’s actions were used to create an artificial green channel.  The RGB data was then further processed in Photoshop CS3 before the individual frames were stitched together using Registar.

This is EPOD number 69 – thank you Jim for continuing to publish my work :)

I have been experimenting with trying to create 3D microscopy images.  In doing this I focus-stack two sets of images and assemble them side by side for stereo viewing.

These two preliminary examples are the head region of a Cabbage White butterfly and the head region of a house fly.  I am beginning to work out the best way to photograph these images.

Taken at 8:25 p.m. on 26/07/2015 this image shows a double rainbow over the New Forest Observatories – and more.

This morning I pushed up the contrast and saturation of the image to take a better, closer look at the rainbows.  I was surprised to see a bunch of blue/violet mini-bows on the inner edge of the primary bow.  Knowing nothing about rainbows I looked this up.  Found out this is what is called a SUPERNUMERARY rainbow.  Live and learn :) :)
