Light rays

This is for the b@w technique challenge. The light from a torch was passed through a comb - only the rays hitting the paper showed up. They highlighted the interference pattern produced by passing through the teeth of the comb. But all of the light rays then refracted through the lens and produced the oval shaped patterns on the other side of the lens.

This is amazing ... never seen anything like it before

[Ulrika]

Whaaat? Looks unreal!

[Kat]

VERY nice!

[Caterina]

Very sophisticated. Are you a physicist?

[Casablanca]

This is really cool, will have to try it!

[Willie]

Super clever, where do you get these ideas?

[Suzanne]

That's fabulous! Thanks for the explanation too

[Ann H. LeFevre]

Very cool- I think if you turned it on it's side so that the comb is at the bottom and the oval pattern is on top, it would look really interesting. mho!

@fbailey LOL FB - they say old science teachers never rally retire!!! :)

@ulla Thanks Ulrika - a good bit of fun. :)

@katsimages Thanks Kat - I'm glad you liked it.

[Rob Z]

@caterina No, nothing so grand. Just a retired science/maths teacher. I taught physics but mainly chemistry and biology. Cheers Rob

@casablanca Hi Casablaca - it's easy to play with. If you rotate the lens a lttle bit more you'll get flower like images - they are cute too.

@wws1968 Hi Willie - thanks for your nice comment. My camera is a small "Point and Shoot" and I'll never be a proper photographer so I just play around with odd ideas that occur to me. Cheers :)

[Rob Z]

@suzanne234 No worries Suzanne - it's always nice to know how things are done. :)

[Rob Z]

@olivetreeann LOL Anne - science teacher here - not an artist!! You spotted it immediately - I only saw it when I followed your suggestion! Thanks heaps!! Cheers Rob

[Ann H. LeFevre]

@robz Wow- I think it looks so cool this way! Glad you decided to ignore gravity and give it a go!

[Rob Z]

@olivetreeann :)

[Granagringa]

brilliant shot...I definitely need to look into this!!!!

[Rob Z]

@granagringa It's fun mucking around with a lens!!

[Anja]
