Now, surely you've not forgotten about the problems of reciprocity failure when taking eleven day exposures on Tri-X. I was hoping not to mention dynamic range or colour bit depth either. Anyway the Hubble does not have movements, so it can't be a PROFESSIONAL camera! There is the matter of colour calibration, since the Hubble image uses data from the near infrared nicmos imager as well as the normal visible range. Those of us struggling with colour targets for profiling might like to look at the target on the Mars rovers <http://marsrovers.jpl.nasa.gov/mission/spacecraft_instru_calibr.html> There is however a growing colour-management conspiracy movement concerning the 'true' colours of Mars -- just do a google search <http://www.google.com/search?q=mars+picture+color+calibration&ie=UTF-8&oe=U TF-8> Next time someone queries the accuracy of some of your colours, point them to Mars. bye for now :-) Keith Cooper =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
