I edited and can confirm that both drag/drop and gui facilitated upload no longer converts to jpg, thanks
So this is what I tried, but it left me more confused. I was hoping to get an output where the hue channel was the ratio (0 to ~2..) and the brightness channel the.. brightness (of either the yellow or cyan channel, probably cyan). I tried the following and got strange results, which I suspect seem strange because I don't understand them, maybe it makes sense to you!
Image calc. Divide yellow/cyan (32-bit float) -> Ratiometric image
Merge channels: Ch 1 = Ratiometric image, Ch 2 = Cyan raw. (Tried both composite and.. not composite)
Type >> RGB to HSB
Image >> Color >> Stack to RGB
Type >> 32-bit
LUT >> Rainbow RGB
and the raw ratiometric image:
However, the values in the Hue and Brightness channels of this HSB stack do not seem to correspond at all to the original ratiometric values, or the brightness values from the cyan channel. Any thoughts?
I wasn't able to find it. Before i delve into this, would I need to develop an ad hoc java plugin, or could this be scripted efficiently (I'm a python guy)? I supose I could just use the same small image and then add the appropriate text in a scripted action.
