Your image gallery is difficult to compare because of different image size.
I requested Georg to reduce the image size to useful 50% of 1000x1280 while the next update.
Also there are some noisy images with a small temperature range. The NETD of the small Lepton sensor is not the best
![Sad :(](https://www.eevblog.com/forum/Smileys/default/sad.gif)
and some thermal subjects haven't sharp edges.
My favorite is the dog.
I reduced Georgs image to the same size of the Flir image.
See the different field of view ;-)
