Screen Calibration for Astrophotography With my recent purchase of a new laptop computer, I am reminded of the importance of having a well calibrated computer monitor for editing and viewing astrophotos. The brightness of my new laptop screen is intense.  It appears to be about 25% brighter than my well-calibrated 23 Inch external IPS monitor.  This results in astrophotography images that are less-than pleasing to the eye.  I had to re-process many of my own photos in the photo gallery, once I discovered that they did not look the way I intended them to on different screens.

Selective Processing for More Detail

Staying Inside - Image Processing The unseasonably cold weather and precipitation we have experienced here in Southern Ontario have given me the perfect opportunity to go through my old astrophotography images and reprocess the data.  I have been advancing my image-processing skills by studying current astronomy images taken by the pros.  Being a creative professional myself, I have always understood and appreciated the power of inspiration. I am always interested in new image-processing techniques, photoshop tutorials and new software that can enhance my work.  Through selective proc…
