Photoshop CS6 Color Settings

Jul 11, 2012 12:05 AM

I was disappointed to see that the CS6 More Options panel still has 8 bit dither. Why isn't it 10 bit by default ? Shouldn't Photoshop be sending 10 bit to monitors with 10 bit LUT for real wide gamut? Some printers are going beyond 8 bit now, also.

    CS6 does have an option for 10 bit display in preferences.

    But dithering is needed for conversions.

    Not following you here, Lundberg02. 

     

    The only mention of 8-bit I see in the More Options panel of Color Settings in CS6, is the box that controls whether 8-bit images use dithering when converting them from one color space to another.

     

    What are you looking at that leads you to reference monitors, 10 bit, LUT, etc.? 

     

    What am I missing?  Or are we looking at different things?

    This is just a conversion option for 8-bit images that may need dithering when converted from one color space to another one.  16-bits images do not need dithering when converted.

    Thanks for the clarification, Chris and Station. I had thought from other threads that CS6 was ok with a 10 bit chain.

    Not sure I really understand why some conversions need dithering but meh.

    Extreme example:  You need an 8-bit sRGB image file from a 16-bit ProPhoto RGB original capture.

    That seems backwards to me, can you offer a bit of explanation?  Dithering is usually used to fake colors not in the palette, right?

    As the description of that option in the screen shot above says, dithering greatly reduces banding artifacts.
