can't do Lab L in Photoshop Elements... is there a workaround?

can't do Lab L in Photoshop Elements... is there a workaround?

2014-02-19 by <paulmwhiting@...>

I'm trying to create a curve for my 1400 and got to an impasse yesterday. I've created a set of 21 density values using a Kodak Q-13 grey scale as a reference, the density figures range from 0 to 1.65. However to load them into the linearization table they need to be in Lab L. The mode tab in Photoshop Elements does not have that option however... does anyone know of a workaround or plugin or something that would make it possible to read my greyscale in Lab L so the eyedropper will read Lab L? And the StedWedge Tool needs to run in CS3 or CS4, which I don't have.

Thank you!

You can use density numbers in the linearization instead of L values.

That's very good news, Roy, thanks so much. I see now in the manual that the linearization table is using density numbers. I had been looking at one of Paul Roark's curves and he was using Lab L numbers, so that's where I got fixated on the Lab L option. And the manual does say QTRip will accept either. Sorry that I missed that!
