Seduced By 1" Sensor ... IR TZ100

One question we can ask of any camera, "will you take IR photos without IR modification?" i.e. Removal of the IR reflective Hot Mirror. For the Panasonic TZ100 with a LensMate and 52-58mm up-size ring and 720 nm IR filter, overcast day @6PM the answer is YES.... The camera was set on P, f was 2.8 ISO 3200 and the exposure was 1/4 second.
The filter used was at least 12 years old and there is what I would call gel crystallization large bar like grain effect. Additionally there is a leak in the LensMate/Up-size ring/IR Filter system both left and right which disappeared when I wrapped my hand around the assembly. Which part is problematic ? ... but it will be fixable.
The usual IR photo red was removed from the photo using Topaz B&W2 classic collection. Some quick tweaking of Noise, exposure, and contrast was done.
Without question a new 720 nm filter will be ordered. Previously with my self-converted Canon G2, the 650 nm filter was too close to viable, 720 great giving foliage white look, 850 OK but dark, and 920 nm way too dark. Images will be posted soon.

I use a IR Converted camera. Works pretty well as long as a get a good calibration of a custom WB for it. I've also shot using a 720, 880, and 900nm, and other glass or gel filters. With a normal camera you get extremely long exposures. A "color" IR image unprocessed should be Magenta and Orange, not Red and Orange. I also find "good" ones have a bit of faint Orchid too. 850 to 900nm should yield B&W IR after PP.

Yes lamiaceae agreed. My converted Canon G2 will register the darker filters, but one is limited with non converted. Like you said, longer exposure than what one can hand hold with out supporting against a tree or post. Focus is usually off for cameras because long wave length IR bends differently thru lenses than viable light. Manual focus may work, if one can see the image bright enough.
Below are two quickies to see if the TZ100 could sense IR at 720 nm. Red is SOOC.

Is it capable of doing a custom white balance? I take a shot of something green, (grass) and use it for white balance. The red cast will go away.

September 21, 2017 Ed Dozier States that: I haven’t owned a camera since the Nikon D60 that would successfully perform a “preset white balance” when I use my Hoya R72 infrared filter. he goes on to show his fruitless attempts to do a custom setting.

The TZ100 does have the usual white correction for various lighting conditions, but it appears that the easiest way is to use software.
