Hi, I am using Affinity Photo extensively for my Deep Sky Astrophotography workflow. I have a new camera that has a bit depth of 12. The FITS files created aren't scaling the 12 bit to 16 bits, i.e., the maximum brightness value is 4095 and never 65535. How is the Astrophotography Stacking tool processing these files? For comparison: in Deep Sky Stacker, I need to define a scaling factor of 16 so that the very dark images are lighter and stars being correctly identified. Thanks in advance! Björn
How about adding the FITS file extension so those of us who do Astrophotography can import the files directly into the Affinity Photo program without having to go through a 3rd party conversion program and stacking them in a 3rd party program then having to convert those LRGB images to TIFF extensions before importing the LRGB TIFF channels to Affinity Photo? It would sure be nice to just import the FITS images into the 'Add' Affinity stacking feature of Affinity then they would be easily moved to the channels without using third party programs before stretching and processing.
I have been doing some processing of astrophotography data. These files usually originate as FITS files which are the raw data files from the telescopes. I process the files using Liberator 3 which then saves the FITS files as TIF files (8, 16, or 32 bit). When I open the saved TIF files in Photo they have large rows switched around or have data that is off the page and missing. When I open the same TIF file in Photoshop the files appear normal. I can then re-save the TIF files out of Photoshop and then Photo opens them correctly. This is on Photo running on Windows 10. Here is a sample TIF file that was saved out of Liberator. When I open this specific file in Photo the image is moved up off the document area and the top part is missing. I can post screen grabs of the errors if other people are not getting the same thing when opening this file. Thanks for any assistance! http://www.spacetelescope.org/projects/fits_liberator/ The file is an image of the Eagle Nebulae if anyone was wondering. 502nmos.zip
