Hi Martin
When your using the Fluke TI25 cam then there is some things you have to note in order to get the correct reading and best use of it.
Dont used it at some odd angle to what your looking at, always at a in a right angle if you can because the cam is using two sensors and if they dont line up then it will not show the images correctly
Dont use the auto scale for the temp/color because it will jump around and at one moment shows like 30c as red and in the next moment as blue if you move the cam just abit, go into the menu and select an scale like 20c min and 80c max and then it will better show the show the correct colors to temparatur factor.
This is also some thing i do with the images on the pc, like when i have 10 images then i set the 10 images to have the same scale ranges so if you put one images next to another one then you know that the red color is the same temp on both images
Dont get to close to the object your looking at, if i remember right from my cam then it most be more then 30cm away from the object.
I know it is nice to get the object to fill the whole images but it will then not take the correct values
Always hold the cam still and then change the focus and if your close to the object then dont aline the to images to make it nice looking but you most make sure the IR image on top has the item in focus and you can clearly see the details even that the images dont aline up.
When you load the images into the pc then you can correct the two images so they better aline, you will see what i mean when your doing this.
if your looking at some shiny surfaces then you have to change the "e" factor to match the item your looking at or you can some very incorrect readings, like black eletric tape there is having a shiny surface can show up on the cam as been hotter then it is.
one trick is if you have an very shiny surface then you can just cover the surface with some white paper tape (dont know what you call it, but it is used when painting thing) the paper tape will quicly heat up to the same temp as the surface but because it has an matt paper finish surface then the cam will read the tempartur more correct.
But as you say it is an good idea to read up on how to use this in the correct way, it is so easy to just point and click but if you dont think about the stuff i have listed here then you will get incorrect and misleading readings.
