how to make vista color more than 8bit?

[ato]

i can't find any option in vista.
vista not support max 48bit color depth(16bit per channel)?

Your eyes don't support it either. How do you expect to see such a small gradations on your monitor?

This also raises the question of why 16 bit on the new HP printers.

[Jonathan Wienke]

Two reasons:

1. In larger color spaces like ProPhoto, 256 gradations per color channel are not enough to avoid visible banding in color gradients.

2. When converting from the source color space (ProPhoto, Adobe RGB, etc.)  to the output device color space (monitor or printer profile), working with more than 8 bits per color channel helps prevent rounding errors that can cause posterization and banding.

>8bit-ber-channel support for all workflow devices is way overdue.

Vista supports a new color managment system - co-developed w/Canon.  WCS or Windows Color System.  Here is a link to a Powerpoint Slide Presentation:

http://download.microsoft.com/download/f/0...t_Ecosystem.ppt

Continued, improved support for ICC-based workflows
New explicitly staged color processing pipeline
New, Simple XML Profile Formats
Easy to edit, verify, understand and extend by third parties
New Visual Model
CIECAM02 instead of reflection-print-like PCS
Built-in baseline device models for common device classes
Extensible by third party plug-in device models
Selectable gamut mapping models
Support for third party plug-in gamut mapping models for proprietary algorithms or improvements on baseline gamut mapping models
Transforms can support black preservation
Support for high dynamic range, wide gamut, high precision color data (up to 32 bpc float)
scRGB with a realistically defined gamut boundary (“wcsRGB”)
New centralized color control panel
Per-user as well as system-wide profile/device associations, defaults, and settings
Non-Admin users can now install/uninstall profiles

Where exactly are you expecting to see an option?

As pointed out in previous posts Windows Vista is substantially different in the way that it handles colour management and printing compared with previous Windows versions. Both 16 bit fixed and floating point data is natively supported by the operating system and changes to the print architecture removes the need to spool to an intermediate file format (e.g. EMF) prior to dispatching to the printer - this should make it much much easier for software developers to write RIPs supporting much more sophisticated print driver (including 16-bit support etc).

Microsoft Vista may be this years must have photo software (even beyond OS X, Lightroom, Aperture and Photoshop CS3).

One thing about Vista that disappoints me is that Microsoft seems to have left out high-bit support from the display pipeline. At one point Vista was supposed to bring greater than 8 bits per channel support with video cards that support it. Right now, there are numerous high-end cards available that can either do true 10 bpc support (Matrox Parhelia, which is way outdated and has no Vista drivers as far as I know), or can at least support 10 bpc processing in the 3D pipeline. However, from everything that MS has said so far, it appears that Vista will be unable to take advantage of those hardware features to allow us to see our photos in greater-than-8bpc clarity.

According to the microsoft release notes in the above presentation vista supports up to 32 bits per channel, following is a direct quote from their presentation.

"Support for high dynamic range, wide gamut, high precision color data (up to 32 bpc float)
scRGB with a realistically defined gamut boundary (“wscRGB”)
Enables color managed proprietary and open RAW workflows"

You may find that the device drivers for your video card only support 8 bpc at this point in time - it is up to the card manufacturers and device driver software developers to deliver greater than 8bpc support - the OS definitely will support it.
