toothbrush???

Yup!

Opened up a new toothbrush and thought it looked sort of interesting. So before brushing my teeth a took a few pictures!
All three are stacks.. 28, 14 and 11 images respectively.

Very cool, Charles! What a good idea for a subject....Lighting is excellent.

Your usual amazing work Charles. You could probably extract money from the manufacturer for pictures like that. Lots of money.

If it interests you why don't you re shoot the same brush after say 100 uses.
See what the worn look appears like at the macro/micros scale.

Great as usual, Charlie. Amazing what appealing motifs you find in such normally trivial things. And some here will appreciate that it´s not our usual "bugs" ´n plants.

May one ask what lenses were used?

As to an ID, I'd say pictured is a ...

...Dr. Best GTX PLUS medium

edit: not "casual", I meant trivial, replaced it.

Nonsense, Betty. Those are only found in continental Europe, check the Range Maps in your guide. Based on the illustration in my Audubon Field Guide, I'm quite convinced this is an Oral-B Medium.

<< I'm quite convinced this is an Oral-B Medium >>

Good catch ... althought it's difficult to be absolutely certain - not being able to see if its handle has longitudinal or transverse ribbing* ... presumably a male?

* one assumes it's not the extremely rare smooth handled variant?

(Super pics, btw Charlie)

Thanks!

But really... this identification stuff is silly..... c'mon!

It's obviously an Oral-B CrossAction Notice the three obvious kineties, and how the direction of the axonomes alternates in each row. And how, when you look at the close-up shots it is obvious what (at first glance) might appear to be cirri, are obviously cilia that move freely independent of each other. (♂... I think. Sexing these is notoriously difficult).

Now I've gotta give Mike B some credit here... he got it down to the correct genus (even got the "medium" part right) but in a group like this "Oral-B ssp." just won't cut it!
Truthfully though, there is simply not enough good information available on these. Just go to this site and enter "Oral B" and then try "Colgate" and you will see what I mean:

Betty.... 80/4 Componon-S for top image, 28/4 Componon for lower two.

Very, very clever Charlie. Such an ordinary day item taken perfectly. BTW, congrats on the way your mind works, I like it !!!

Very cool! Looks like a bit of fibre optic cable!

That's an interesting observation Larry.

It might be effective to illuminate the base of one cluster of bristles (the dark-blue tipped) and then photograph an avenue/part through the cluster using the 28/4 Componon or similar.

If one was to drill a 3mm hole in the toothbrush and send the illumination up through the center of one cluster via the base, the light should radiate and filter upward and outward throughout the whole cluster. The bristles should interact with the light and serve as light guides.

Craig... please don't use the words "drill" and "tooth" in the same sentence around me... :-&
