Light Pollution Problem

Hi all,

I enjoy taking wide field pics with my Canon 350D, but I find that the pics are heavily light polluted. I have photoshop 7, how do I clean up my pics and reduce the light pollution in them?

Thanks

Neill

Hi Neill.
I've just begun to get into astrophotography lately and I've run into the same problem.
I guess it's only the lucky few who don't have any light pollution on thier dorestep.
So, as I'm sure you're aware, the best way to deal with it is not to have any in the first place.
I've spent a good bit of time driving around looking for dark sites to observe and shoot from. The darkest site I've found although to the naked eye looks great...and is fine for visual observing...still picks up some pollution.

You can try and beat it with Light Pollution filters.
A poster over on 'cloudy nights' tested lots to see what he thought was the best and shows the results:

Other than that there is an e-book, "A Guide to Astrophotography with DSLR Cameras" which has a section on prossesing images in Photoshop...

Hope this helps.

Happy shooting!

Hi,

That looks very useful.

Thanks

Hi Lads, I have the same problem, the only way to ensure no LP is drive to a dark site, but I find that taking some dark frames (same exposure and ISO) on your camera but with the cap on the lens, plus a little processing in photoshop can reduce the effect.
