Some of my photos have a green tint to them. How do I get rid of it?
I recently processed a bunch of photos I took of the Orion nebula last year and I am having some troubles. I used DSS to stack about 600 3.2s exposures with about 50 darks, bias and flats. I then processed the image in Photoshop, mostly following this tutorial (I followed only the parts where he adjusted levels and curves, as everything else was paid plugins)
It seems no matter what I do in Photoshop, it always ends up having a slight green tint to my photo. This was the best result I could get: http://ift.tt/2cOzvet
This was taken using a Canon 450D at 200mm, f/6.3 and ISO 1600.
I thought it might could have been light pollution, as I took it from the outskirts of a city (not a large one, but a city none the less). But I have taken several other photos from pretty much the same area with the same camera that turned out way better using the same processing method.
Is this a common problem? Is there anything I can do in Photoshop to bring out the actual colors of the nebula and surrounding stars? Or do I just have shit data for this particular image?
