Ultra macro with Q and an old TV screen = RGB matrix fun!

Ever wonder what the actual pixels on your TV look like?

I achieved my goal of a clean super closeup shot of just the three primary color phosphors.

Taken with a Spiratone Macrotar 35/3.5 lens on a fully racked out bellows plus an extra 36mm extension and backed with a Pentax Q cam!



(Actual live view ultra macro setup in front of my vintage CRT TV.)

I don’t know what the magnification factor is, but I assure you it is very bigly!

Excellent image Kayakfari. Very creative. You threw the whole contents of your camera bag at this image. Then topped it off with the Q. Super!
Thanks for sharing,

This is awesome. Haven't used my Q in years but this is why I'm keeping it. One of these days I want to do super tiny macro stuff, but not this super tiny.

I've got a couple old tube TVs kicking around I haven't been able to bring myself to toss. You're not helping!

And you're not helping my GAS requirement to keep a Q-S1 on the short list.

Thank you!

Nice picture and equipment! I had a bit of in-brain battle.

"Look at that super macro shot, that's nice!"
"No I don't need bellows."
"Wrong answer, the question is do I want it. Local person is selling Spiratone bellows and a lens with Pentax H2 as a kit."
"That looked dirty-ish on the picture, I don't have M42 adapter, and what do I do with H2?"
"Well, I can keep H2 or sell for cheap to buy a M42-K adapter or three, really no excuse not to buy?"
"I already have macro equipments that work!"
"Sure, but only 1:2 physical magnification for my nicer lenses! Look at that super duper macro!"
"I, DON'T, NEED, BELLOWS..." (Inhaaaale, exhaaaale, inhaaaale, exhaaaale....)

True story.

Funny story Kwb. A little dance we all go thru.

I am lucky to have a Pentax K mount bellows bought years ago. I enjoy using the Q and a reversed 50mm El- Nikkor on it. Extreme macro isn't easy but it is fun.

Thanks,

Thanks guyz, I thought you might get a kick out of this.

The TV dates back to 1997 and now cuts out to all white after about 12-15 mins on, so time to recycle!
But not before I get the phosphor shot ..lol!
I wasn't sure I could get that close, but the auto bellows and extension made it happen. Very difficult to focus, exposures about 1/4 sec and up at iso 1600. Stopped down to 8 or 11 as the CRT screen is not actually flat anyways.
Triggered with the IR remote that's how I got the GIF phosphor glow sequence.



The Macrotar is a T mount, FYI, but you could also use a reversed lens or another enlarger lens.
