- Thread-topic: Lab decimal PS Re: colorsync-users Digest, Vol 21, Issue 3
Photoshop can display Lab values to two decimal places. Change the Color Picker
in the info palette to 32 bit. You can’t enter a decimal value in the Color
Picker though. I do find displaying Lab to two decimals useful in our workflows.
Latest release version, Photoshop 25.3.1 has the bug. Fixed in Beta.

Meanwhile, Lightroom Classic does show Lab values with decimals and doesn?t
truncate the values ( of ?Imaginary? colors that fall outside of it) to +/- 127
like Photoshop. I?ve begged the PS team to implement the same scale in
Photoshop since Lightroom Classic could support Lab values, and it fell on deaf
ears. Why can?t two Adobe apps with the same processing engine share the same
scales?
So, we need a massive number of Photoshop users to keep making the request.

Yes good point Andrew. I use those Lab values in Lightroom everyday and find
the one decimal to be perfect for image development. Two decimals would be
better in InDesign, PS and Illustrator. InDesign is the best citizen as it
already does this.
And yes, ?over-range? lab values are real and needed! I photographed some
artwork yesterday that used over-range vales...
