Visually testing out the spectral sensitivity of the IPhone 16 Pro with the Baader Near Infrared 685nm pass filter.

I did this a year ago, so there are plenty more images to come from my tests.

Short Wave Infrared seen with the iPhone 16 pro.
I used the Baader NIR 685nm pass filter, in combination with the Baader Swan Band filter, along with 10-30 seconds of long exposure.

@dumbsly.com

also scientists in case people don’t want you to share results with others and the world

maybe this could come in handy?

i mean like even the chance it could help

is why i’m posting this

hey #altgov

maybe you know this

maybe it doesn’t help

but private key encryption

over amateur radio frequencies

with static used as the message

would be almost indistinguishable

from background noise

without holding the key

A super simple IR radiation demo. Use a remote control... Any remote control & point it towards your mobile camera. #EMspectrum
