I'm still trying to get the scenario straight in my head but on the first interpretation it does sound like a colour space issue, likely the monitor colour space and the interactions between it and colour space aware applications vs non-colour space aware applications (including RAW codecs). In short I would suggest at least temporarily setting the display colour space to sRGB and ensure that the saved images are converted to sRGB colour space using a relative rendering intent in the CMS such as perceptual prior to saving and then seeing then how the colours compare in each scenario. -- Rob Studdert (Digital Image Studio) Tel: +61-418-166-870 UTC +10 Hours Gmail, eBay, Skype, Twitter, Facebook, Picasa: distudio -- 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.
