OK, I've investigated in a bit more detail, and yes indeed, the viewing condition setting has a bug. Basically "mt" is really "pc", "mb" is "mt", "md" is "mb" etc.
Ah, OK - good to know I wasn't imagining it!
So one workaround is to use "-cjm" to get the effect you want, or the other is to use -cs:m, since this is the dominant difference between mt and md.
OK, thanks - I shall try those and see what happens.
[Are you getting images to look good on your monitor and then printing them out ?
In some cases, yes - in others they're straight off the camera, or from a third-party source.
Would you describe your monitor viewing situation as "dim" rather than "typical" ? ]
Somewhere in between, I guess. It's probably towards the brighter end of "domestic" lighting, would be slightly dim for office lighting. I do keep the brightness of the monitor fairly low, though - in a deliberate attempt to make screen-to-print matching easier. With absolute colorimetric intent this is pretty successful too - see:
http://blackfiveimaging.co.uk/temp/ScreenPrintMatch.jpg(The visible discrepancies there come from differing illumination angle, the prints not wanting to stay flat, and the camera seeing colours slightly differently from the eye - the match is closer still in "real life")
As far as photo printing goes, though, my goal isn't to produce prints that look perfect in a D50 light booth - it's to produce photo prints that look pretty good even under typical domestic (i.e. lousy!) lighting, and in the absence of a -dprintunderlousylighting flag, -cmd gets pressed into service!
Loving illumread, by the way!It would be nice to be able to average several reading of the real lightsource, though - because there are actually several in here - a fluorescent tube providing main lighting, and a Colour Confidence Grafilight providing some high-CRI light too - then daylight in the daytime of course. I can only point the instrument at one light source at a time... ;)
Thanks as always for the great work All the best -- Alastair M. Robinson
