content: Hello. I would like to know if your software is suitable for all cameras or specifically for 336 or 640. I want to clarify in order not to break my camera, I have a tau2 640 * 512 30 hertz camera. Thanks for the answer.

content: Thank you.I already tweaked with that for the whole day...I suspect it's the problem with bias.Even before update, if you set the lens aperture too high, it will have column noise, and if set too low, time constant will be very long. So I already played with that magic parameter for days...Now after update, I seems cannot get it right, with best value I can guess, the column noise is still way too high...

content: I suspect this v2.8 firmware is for TAU+, Flir also made special firmware for Boson+, with higher version number.I'm guessing this because per my testing, the v2.8 is aggressively tuned for max contrast and detail using factory default settings, which is huge difference compared with all other versions.With v2.8, the settings no longer need tweaks, the image shown with default settings is almost the same as my manually tuned Boson, which is impossible with previous versions, no matter the parameters used.
