Fun with thermal imaging

[Scott Gilligan, CMI]

Here is something for everyone....

Attached are two images taken using thermal imaging. Anyone want to try reproducing them with their imager.

Any Level 1,2, or 3 guys out there try to keep from posting any comments and giving the secret away to everyone else. Lets try to make this a learning experience.

wow, very nice Scott!

Show us some more!

I love the reflection through the glass in the top one. Once Scott reveals how this was done, the reflection is even more impressive.

Very nice tuning on the second one, Scott.

Jason: you meant "off the glass" didn't you? IR can't pass through glass!

Look at the second picture Dave. IR can pass through glass. That is an image of the actual filament, not a reflection. I know you know how this was done and can be reproduced, but lets hear it from some of the other guys.

[Bob Elliott]

Not being an IR guy my first thought was this image had to be taken immediately after the bulb was lit in order to produce the image before the the glass heated up.

Reason is that once the bulb has been lit for a while you would only see the shape of the glass as it heats up and not the filament.

How many here think IR can pass through glass?!

I think Scott is playing tricks on us with photoshop!

Maybe the Fusion option?

It can pass through glass.
Just not double reflective layers and UV rays.

Why can't I see peoples eyes through their glasses?

[David A. Andersen]

I can't see it with my camera. Even with a filter. How ccome he can?

I would assume if that is true that it is due to the fact you are getting distortion from reflective quality (or distortion) of bent light through the highly concave or convex thicker glass.
Light bulb glass is very thin and also has a vacuum which does not retain heat inside it.Your skin temperature would radiate into a thick glass.

Just guessing.
