I'm not think so,
This way you have 16 stops isn't it ?
And a film only have about 5 or 6 !
Remember that raising one stop means multiply (X2) the amount of light.
So, in my opinion, try: 1,2,4,8,16,32,64,128,256.

Subject: counting stops in Photoshop
hi all!
I'd like your advice on this...
I need to raise the brightness of some images in photoshop exactly one
f/stop.
How can i achieve this?
I am thinking that there are 256 units between black and white, that's
16x16. So if we assume that there also 16 stops between black and white
would moving the slider in the levels window 16 units, give mea 1 stop
worth of difference?
just a moment I googled something out:
powerretouche.com/Exposure_plugin_tutorial.htm
Question still remains though, thanks, kostas

so... no matter what, CHEER UP MY FRIENDS! Life is too precious to jump
the other side of the fence...
