How to create a thermography effect filter for images inside FF

Here is using thermal spectrum

And this one of a boring colors aerial city

Also It can be even better adding additional colors to the gradient ax shown here

There are 10 variants based on one of the initial color, and 10 Wide Dynamic Range variants with the dense colors and more details. You can use these tools for Creative Effects

The top left on the grid is the original one

And this nearly Chrome and black wheel you get a colorful gradient wheel

And this one remembers me from the built-in FF tree

From the Library I have found only these two filter that may be similar to what I have shown above BUT after testing it, it does NOT work in the same way and the result is not the same using the same original images shown in the examples

Please, do you know any other possible filter that can do something similar ?

Thanks very much

Thanks very much for trying to do something with this.

Could this be ?



PS: perhaps using rainbow gradient and a loop to have a wider range of colors. Sorry if i am wrong, still fresh and still learning haha

Here are some of the test images from the above examples to use as source images to know if they could get similar results

This is the testing image used to create the preset that is available in the filter that show what could be possible

Sorry, Forgot to tell that the thermography filter testing above is for FF 10

Here is the first source image as an example after using the filter made by Theob and with my own settings

But there is still much to do to get something useful similar to the examples above

Whoops...duplication

Hello, i see what you mean now. So it was wrong since the beginning haha. I thought it was something to do with the channels themselves. Perhaps elevation gradient could be used as gradient map instead ?. Let me try it again. Cheers !

Here is the code. FF7 and above. Very simple use of HSB to create an elevation map. Most thermographs are 5 color (BCGYR, coolest to warmest). Another adjustment would be changing the gradient positions...

Yes, it is arbitrary. False coloring, a favorite of graphic artists and painters for a long time. So I agree, going for a look not technical accuracy is the point

No, I do not mean that you was wrong in any way, your idea is right and well, I agree that maybe if you want to have an accurate technical termography it may not be the right way, but I did like your idea and how you have done it and it can be expanded and mixed with other things to make it better.

YES, you are right, sorry that I did not tell this from start, I do NOT want to have a perfect technical correct simulation of a thermography effect, I just want something that "looks like" the effect but does not need to match the real effect, and can be much different colors.

Yes, I agree, that it should not really be called Thermography, it could be called Gradient map coloring, or false gradient coloring, or Look up Coloring, as the Thermography by itself is limited
