Those images I took of the vaulted ceiling - the outside temp was -20c

Something to keep in mind is reflectivity and emisivity of an item in the picture. Window glass is highly reflective and a thermal picture of it is not accurate at all. You will see a reflection of what's around it and not a true heat signature.

Precisely. I see it all the time with the flir i7 I use at work. Glass and shinny stainless steel are highly deceptive.
In a few places flat black vinyl stickers have been attached to the stainless steel piping and surfaces, because it will read 80'F when reality its more like 135'F, or the stainless will be reflecting the temperature of a near by surface giving a totally false reading.

For home windows I would try to tape a sheet of paper to the window to get a real indication of the temperature.

I guess I can try taping a sheet of paper to a reflective surface at work and testing it with the i7 and see if it actually works.
I think a square of paper taped next to one of those vinyl stickers would be the ideal test to see if the sheet of paper can transfer and emit a heat signature from a reflective surface like the black vinyl stickers.

cool
 

Friend brought his Seek by yesterday. Way cool device.
Seems like it's compatible with relatively few of the newer
Android phones.
I don't need a phone, so buying one to go with the Seek
pushes the cost way up into the range of better imagers.
Having the ability to borrow one reduces the urgency
to buy one.
Hopefully, they'll have software to run it on a laptop
sometime soon.

Sorry I dropped off after I started this thread. I'm going to school and trying to keep school as number one priority. Second week of June I will be done. Yay! Anyway, I keep throwing money at this thing. I broke down and bought the $45 macro filter off ebay. It didn't help at all. Made it worse. The one picture that is clearer is without the filter. The other one is with it on. I guess it is what it is.

I think the Macro is only good for extreme close ups

I thought that too so I tried it on the GFI outlet like I did when I first got it. Made no difference.

I am wondering if your phones camera is without a focus , some are like that and not all of the apps work that well with them.

Cool! This is my dream to have ir camera or seek thermal gadget! For now is too expensive for me :(

The photos I took with the Rent-a-Flir do not agree with what you have written.
