It may sound insane, but I decided to reprocess many of the images on the site and post them again. Every UNCALIBRATED pc or laptop screen will show an image differently. Laptop and PC screens need to be calibrated (using a calibration devive, which nowadays costs you roundabout €80 to €130), but hardly anyone does this unless they dabble with photography a lot. A calibrated screen usually has a lower contrast setting, less colour saturation and less blueish colours than an uncalibrated screen. Uncalibrated screens unvariably are too blue. I have noted that a lot of amateurs active in astrophotography, up to using sometimes quite sophisticated image processing techniques etc., amazingly enough do not calibrate their screens. In that case, any image processing is basically useless! - Marco ----- Dr Marco Langbroek - SatTrackCam Leiden, the Netherlands. e-mail: sattrackcam@wanadoo.nl Cospar 4353 (Leiden): 52.15412 N, 4.49081 E (WGS84), +0 m ASL Cospar 4354 (De Wilck): 52.11685 N, 4.56016 E (WGS84), -2 m ASL SatTrackCam: http://home.wanadoo.nl/marco.langbroek/satcam.html Station (b)log: http://sattrackcam.blogspot.com ----- _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
