445nm burn-in gone wrong

...or very right, depending on your definitions of what constitutes a productive night.

In any case, I threw the 445 for my projector together, and was running it to take a few temperature readings, as well as temperature stability measurements. That usually implies long periods of sitting around and doing nothing.

Because I don't have WiFi, I couldn't really do anything productive on my laptop (or so that was my excuse anyway. :whistle:).

So, instead of sitting around for half an hour, I fired up my red and green as well. And, well, it went from there.

Enjoy.

Throw some green into the mix.

Auto white balance skews the green towards the blue end of the spectrum. It's interesting; there's a rule regarding colour blending for a nice cyan/white with 445/532 which we should all know well enough.

Time to throw some red into the mix

Funny thing is, even though the red is the most powerful out of them all, being 658nm means it isn't very visible, both to the camera and to the eye.

Of course, never forget the OD3 attenuation goggles for 190-550nm. A must when working with the Class IV blue. It's not just uncomfortable to look at, diffuse reflections can cause permanent retinal damage.

Once again, the red is barely visible.

Ooh, shadows.

And now in three colours

That's the phone I was using to take pictures with

And this is how it's done:

Oh, it didn't end there.

To them: HOLY F#CK WHAT WAS IN THE PILLS I JUST TOOK?

It's all in the first line of the post :p

Depending on what you may call a productive night, that is.

I thought this was great! Thank you for all the pics! That looks like you had a lot of fun. I'm not sure which pic was the best. And not "best" as in visual value, but sentimental and knowledgeable value! Of course the Lumia was awesome.

Encore, please!

I think I have that same ultrafire :crackup:

I always liked the mismatch of the shadows. Conversely, I've always hated troubleshooting color registration issues on our color printers.

Nice work on the blue labby.

Nice camera phone pics Gonin.

I will put some(&vids too) once my two massive Lumia projectors are done.
One will have five wheels and seven SSlasers, the other will not be portable as I am using red ang green HeNes and my ML argon (thru a diffraction grating).

If you like them I will sell you a nice 1/3rpm set up- plug(120vac) and play with interchangable glass wheels. Pm for details.
