Applying LUT that handles negative pixels

[Corey Duke]

Hello,

I am processing video files in a way that requires subtracting the first frame from the rest (so we can monitor changes in pixel values). In doing this I create some pixels which hold a negative value (32 bit floating images). Is there a way to apply a LUT that can handle these negative values? I am very open to any suggestions. Perhaps there is a way to apply a LUT that colors changes that occur across the z-stack?

Thanks in advance for any and all help!

Yes - choose your favourite LUT from the menu and adjust brightness and contrast: the LUT will get scaled to fit the pixel values which are selected by B&C to be displayed.
