For a variety of reasons I've not been able to play around with the microscopes, or do much photography of any type lately. But while doing some breakfast dishes I decided to have a look at the soap bubbles with the Canon 65mm MPE. Interesting but a little dull all white, so I got out the food coloring. I suppose its been done a million times, but sometimes you just need to take a picture or two... Wink

Lovely and interesting! These images make clear how the liquid obviously collects into thick strands along the intersections of faces. I think the addition of the color really helps a lot for that. It gives the strands a "solid" appearance that they don't have when clear.

Charles,

Beautiful set!

What is food coloring (sorry for my ignorance)?

Rogelio > Food coloring is exactly what it sounds like, food coloring. You can use it in white frosting for sugar cookies during the holidays, and has a variety of culinary (or non culinary in this case) uses.

Charles > Really cool shots. I did this with my 65mm as well, but I wasnt smart enough to drop some food coloring in it. I was going to go for the soaps "rainbowish" colors in the photo. Didnt turn out the way I had expected or desired. Doing that really enhances the feel. Really Star Trekkie... Very Happy

Charlie,

I'm fascinated by the exhibited structure, (possibly) random and definitely beautiful.


Rogelio,
Food colouring can be purchased as a liquid in a small bottle at your local supermarket/grocery store (usually found near boxes of cake mix, etc). It has many uses when a non toxic, coloured additive is required.

Thanks all for the kind comments.

Never imagined my morning bowl of granola would end up producing images I would be posting here! Wink

Beautifully executed, impeccable images (as usual Smile). Reminiscent of Fritz Goro's soap bubbles.

Wow! Very nice!
Are these pics negatives?
Or how did you produce the illumination?

Not negatives or inverted... the food dye concentrates and spreads along the "seams" between the bubbles, making them "dark". The bowl was on the counter next to the sink (waiting to be washed Wink) The illumination was from a window behind it that had overcast sky with an occasional glint of sunlight breaking through.


It is not unusual to see highly similar shapes and forms in nature in subjects of very different sizes and types. (Like the way I "see" layered mountain ridge-lines when I photograph mushroom gills under the microscope).
While I was taking these I had a strong déjà vu experience. They appear so similar to the alga hydrodictyon that I photographed way back in 2004 (Google "hydrodictyon" and check out additional images to see an amazing similarity with these bubbles):


(This was actually one of the very first microscope shots I took and posted here in July 2004. Mediocre 40X objective, Canon 10D, and a complete digital novice).

Really cool looking. The second and third ones are great Smile

I like the lighting, you say this was all window light?
