of dishwashing detergent again.....
Incident brightfield, Objective 10x, Flash, DSLR.
Thanks for looking,

Hi

Well , not much microscopy in this picture
more Photoshop hocus pocus

Gerd,

Very nice shot!

Anything special to get this? What dilution on the dishwashing solution?

Wonder how it would look in darkfield.

You've inspired me to try this myself.

All the best,
Mike

Amazing the amount of refraction that goes on in dish detergent. Very colorful Gerd, I have yet to try this myself.

Hi Perl, why should i post PS hocus-pocus in this Community ? There are enough
PS forums to discuss that. Did you ever take a closer look to soap bubbles, perhaps
under the Microscope ? Obviously you did not.
This is a photomicrography of a thin film of dishwashing detergent under incident lighting.
No crop, no image processing, just resize. Thanks,
Gerd

Nope - have not done that
but it look very unreal , look like an 8 bit
picture

Hello Ken, Hello Mike,
thanks for the kind comments,. I use a plastic object slide with a hole in it of about 10mm diameter.
At the upper end, towards the Microscope Objective, there is a chamfer, to keep the soap film in
a defined position. I tried different dishwashing detergents, 1 : 1 solution in water. Some keep
several minutes, other only some seconds. A wide field for experiments.
Mike, if it is incident darkfield, it will work well. But you can see anything, if you use transmitted light
contrasting methods, the light has to come from above.
Have fun.
Best regards, Gerd

Thanks, Perl,
please try it yourself, it's absolutely amazing, and addictive !
These 8 bit like steps come from the different film thickness in the soap film
I think, the tenside molecules form constantly changing layers of different thickness,
the resulting optical retardation make different interference colours.

Wow, If you could make movie from this you could use it as a music clip for a psychedelic band!

I think this is an amazing pic.

With all this microscopic stuff and anything else on the forum, I'd hope people would admit to using photoshop etc. (I don't do that myself cos it's too time cosuming and no fun).

I once took a normal photo of a bubble on a bottle of sparking water and was quite amazed by the result - no post processing. When I showed it to a friend ( a tech head) he said he knew people who created photos like that in Photoshop!! It took me less than a second - much quicker than PS!!!
