And even right now, with what I know, I am still wondering what RGB space has a
gamma of Dot Gain 20%? For when I am tweaking the layered Dot Gain 20% Gray
Space files I'm given.
Sorry, I mis-remembered the color space of those odd gray color space files I
sometimes get handed. They were in 'Generic Gray'.
Regards Peter

Hi Lars
Thanks for that reply.
<snip>
First make sure the Gray working space, the RGB working space and the image
profile have the same gamma, such as gamma 2.2. This is because when the
readout mode is not same as the image mode, the info panel uses the working
space profile(s) to convert from image to the readout mode. Using the same
gamma on all profiles assures that gray values convert to same RGB values.
Thanks Lars. Thats a very clever solution. But I have to say that outside of a
few photoshop users on this colorsync list, it's not a solution many photoshop
users would think of to answer the question "what's the (0-255) value of the
gray file I'm working on?".
And even right now, with what I know, I am still wondering what RGB space has a
gamma of Dot Gain 20%? For when I am tweaking the layered Dot Gain 20% Gray
Space files I'm given.
So I am wondering if you could advocate for Adobe to make the task of
inspecting the 0-255 RGB values of grayscale images easier for us that are less
technically inclined.
Much Thanks
Peter Miles
