My step wedge is nothing more than done by numbers - in hex the brightness 
values set in PS are
0, 10, 20,30,40,50,60,70,80,90,A0,B0,C0,D0,E0,F0,FF.  I am not totally 
convinced that each step should look the same difference or not on a 
properly adjusted screen - which was my original question, and I still 
don't know!  I think it *should*, even though I can't get this on my screen 
without making extreme adjustments and silly figures for gamma.

I think I have been tagging my images with profiles, although it would only 
have been with sRGB unless I have made a monumental error.
