Okay, back to making pretty pictures.
While manipulating the data to make details visible is certainly useful, I like to start by getting all the thermal details with a distinct color palette. While in some cases this produces some cool isotherms I recognize that in many cases it makes a rather "busy" image as well as noisy. I do like the "grass" look here, though, even if it is noisy.
Someone who prefers gray scale only might instead apply the entire gray scale to the background & then do the same to the deer & then combine the 2 to get the following. Not much more detail in the deer, but noticeably more in the background.
In similar fashion, taking the green from my distinct color palette & applying Seek's "Amber" palette to the deer yields brown deer on green grass (which I think looks pretty cool).
As far as simply applying a single palette, I think my favorite is the standard "iron" palette:
And applying Seek's "HiLo" palette gives us deer on snow.
