I used the term "colorimeter" loosely, meaning a hardware display calibration tool. A display calibration tool (hardware and software from Xrite or Colorvision, or similar) would do the right thing presuming it is compatible with your display. I suspect that "wide gamut" means 16bit quantization for the display device rather than 8bit. I've seen this debate on other forums. IMO, this kind of wide gamut display configuration only makes sense to work with if you were also working with a high-end printer that could also image 16bit data quantization on output, and that was your intent. It doesn't make sense to work on a wide gamut configured display if the output target is other displays, 99% of which are going to be configured as 8bit quantization devices. If you want to be sure to have the right hardware to calibrate and profile your display for wide gamut setup, be sure to research on the hardware/software providers' websites and info pages so that you are certain to get compatible hardware and software for the task. But I think it is mostly a waste of time. The sRGB profile you've applied isn't the best one to have for the display, but if it's doing the job satisfactorily for your needs, life is good. -- Godfrey godfreydigiorgi.posterous.com -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
