Well, I’m still writing it… stuck in the “Silmarillion Syndrome” stage 🤣

Give me a couple years, I’ll remember where to find ya! 🧐

Nice! That’s like the cover of a dark fantasy novel…

I feel that.

That’s more snow than we got all year right there.

As long as you get the treatment, I guess it doesn’t matter how many hands the bill jumps through like a hot potato, eh?

I recall this poster of a road painting crew who’d painted a double-yellow line down the middle of a road and also right over the bulging carcass of a dead armadillo… the poster was given out for the annual “Not My Job Award” down at the city works…

Oh, that’s lovely - nicely done!

That’s an amazing capture!

I see this, and it’s like the ultimate argument against plural marriage…

(I have my fire-retardant magic Mormon undies on… roast me!!) 🤣

Thank you - I relayed that to ArtGeek 😊🙏🏻

I got the 50% off a Kolari thread, and thought maybe it was legit….

I believe I overcomplicated it, giving him answers from my opaque 830 view instead of his 720. My bad - will keep to my 830nm lane unless I decide to give 720 a try…

Thanks again! 😎

I asked Sheri:

"I believe it’s about 3%…of course 830 is opaque. Just a guess…but I these days everyone is an expert! 🤣 I’ve also read 50%, but disagree. I began with film, took ten years for me to figure out processing, no one was doing digital ir 20 years ago. A long frustrating journey that was”

You’re very welcome.

I’ve had a little back and forth with ArtGeek (Ken Tryon) regarding 720nm infrared (which differs significantly from my 830nm background), and I’m wondering if you know the answer to:

How much visible light does a 720nm filter allow to pass through? I got 3 different answers.

Actually, for 720, I’m gonna have to ask Sheri Mabe. I think 720 is her wavelength.

Sorry man, I’m not trying to mess with you - I’ve now found 3 different sources and got 3 different answers on how much visible light it lets through.

Must be some, because the blue there is way below 720nm…

I got reading up on 720 and that conversion allows some visible light through up to 720 (up to 50%) then 100% over 720.

Weird about only colour RAW + jpeg… but yes, I have an R5, and you can shoot in RAW + jpegs in with B&W image preview (the jpeg comes out B&W, and the RAW still comes out colour)

Am I hearing that you work at a hospital, and the insurance they offer does not cover the cost of treatment for infections acquired at the hospital? And the hospital itself therefore pays for treatment? Am I reading that correctly?

The 50% pass for visible light actually explains why all the 720 shooters I know don’t lose many stops of light, but my 830 bodies are all about 4 stops underexposed at the same settings (because the 830 is a hard block - no 50% pass).

Glad I found that; I’d always wondered what I was doing wrong!

Yeah, the shorter (higher) wavelengths above 720 a red and above.

My 830nm RAW shots are grossly magenta (I shoot RAW + jpeg, and the jpegs always look like they’ve already spent an hour in lightroom… but I’m a mono guy, so that’s what I was aiming for)

Ouch. Yes, cars v human doesn’t often end well…

And there’s no better place to get sick than in a hospital!

Might have to order this…

Forgive me, I’m much more familiar with the 830nm hard B&W conversions, which really do block all visible light and IR below 830nm.

The 50% bypass of the 720 conversion is unique in that way; not sure if they leave the UV filter in place for that one.

A full spectrum allows everything, even UV.

I believe a 720nm filter has a ~50% pass frequency which will allow limited (1/2 of) visible light below 720, but allows all light above 720 (and most camera sensors don’t see much over 1100nm).

Standard sensors have UV filters on top, which would cut UV… but maybe the 720 conversion allows it?

Oh sh!t, I'm having a brain day...

No, your 720nm IR converted Powershot will NOT see the UV light at all. Your cutoff filter is 720, which allows some red/magenta passthrough plus the IR spectrum, but the 100-400nm UV light will be blocked.

Sorry, took me a sec to re-digest that...

It will, though typically modern sensors have a digital filter that dilutes it (this is why film users still need screw-on UV filters, and digital don’t)

But if UV’s your huckleberry, may I refer you to one Ms Rain Hayes, mistress of the UVIVF floral photography medium…

That’s exactly what I used to tell my daughter… before my wife made me change her name to Cassie…

Aye, who can tell. And next winter, it’ll be different anyways…

Yeah, 2 hours is quite the trek when it’s that frosty. I do it out here when I head to Banff National Park, but there’s not a lot of traffic (which is good). I trust me - it’s the thousand other cars I’m wary of. Better if it’s only a dozen or two cars…

yup 😎

As long as it shines above you 720nm wavelength, your camera will see it.

There are cheaper ones, but the Darkbeam I’ve got is a beast - very bright; throws it far 😎

Saw this… thought of you:

One last little IR blurb:

You know how you can light-paint with a flash (or) flashlight with a regular camera? You can light paint with an IR flashlight if the sun’s not giving you much to work with.

Google this: DARKBEAM IR Flashlight Infrared 850nm Light LED

Can be used in day or even at night

LoL @ the Scratch n Sniff 💩

I would totally wear that on a shirt…
