Just being pedantic but you allude in the above paragraph that Colorspace is dependent on "dynamic range" however it's not, inappropriate choice of WB may cause some colours to clip in certain circumstances but it doesn't alter the sensors colour response. Just consider the scenario of a sensor which has acute sensitivity to near UV and near visible IR but very poor green response. It could feed into a 4 bit ADC but would still require a very wide colorspace to adequately describe/contain it's colour response. -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
