In fact book mark the whole Smartshooter.com site. Lots of good info here.
This article cites the fact that there are no printers or monitors that can reproduce the spectrum of either RGB or sRGB. . .yet. One of the folks from GG commented that he works for the day that it will be possible to reproduce RGB 1998 and saves for that day. Might happen but I wonder if we'll live to see it and if in fact it will be visible to the nekkid eye. We at our studio have elected to set the cameras to sRGB, Work in sRGB and send our files out in sRGB (since that is what our's and most every other lab request). The only exception to that is when we are preparing images that will be larger than 11x14 then we open the raw file and work from there. We shoot both 8Meg and 11Meg cameras so the jpeg fine files from these cameras produce great images up to 8x10 and in most cases 11x14's. Our idea is to save the time and confusion of constant conversions.
Now who can tell me about BruceRGB?
