Lightbulb Easy infrared photography with Pearl 8100

Please Login to Remove!

I just spent a few hours googling and browsing on the subject of IR photography, cameras, camera mods, etc. and I decided to find out if my Canon camera sees IR from a remote control (which it barely does.)

Then, on a whim, i tried the pearl camera with decent success.

So i decided to try out a filter mod on the pearl. I located some film negatives, and slipped a piece of exposed and developed negative (it's BLACK) in front of the camera lens.

Worked GREAT. It's an instant IR camera!

Example shot is a parking lot on a rainy day.

Default ?

Do you have to have a IR source for this to work? or do you just have to put a negative film strip in front of it?

Actually the real purpose is "to see the invisible light".
I remember there was a whole IR controversy about a Sony camcorder a few years ago -- something about seeing through otherwise opaque fabrics at the beach... ('nuff said)

If you don't believe me, google it.

Yes you need an IR source.
When photographing outdoors, the IR source is the sun of course.

The exposed negative is just used to filter out "visible" light. This camera should also work in pitch black with an IR source -- without any filtering.
(anybody have one? take some pics and post up!)

As for filter materials, I'm sure there are dozens of different types that can be used. Exposed negatives are not very high quality as filters - they leak a bit of red. But the real plus is they're cheap and readily available.

Ok... a couple more random shots

Air conditioner's remote control, with what looks like a nasty internal camera reflection?!

...and a filtered shot, with lots of silvery "ir-glowy" foliage - and a RED truck kinda showing through.

Wow it works, I was trying it out with a little doubt and am pleasantly surprised. I have a high intensity IR light source I am going to dig out tomorrow and have some fun. I will post some pics.

Infrared???? What about X-Ray vision? Can it take snap a picture and see through buildings?? That would really impress me and a few others...
