The magic of photoshop

I took a 15 second pic of the night sky last month - here

It is a lores, web friendly version, fairly compressed.

Anyway, I took the original into photoshop, ramped up the contrast a
bit, and its amazing how much more detail you can see. It's also quite
amazing how much light pollution the moon gives off !

amazing isn't it?

i do star-trail photos occasionally, and while they look good as-is, bumping
the contrast up can have amazing effects - and as they are trails, you can
see the fainter stars clearly too - as they are now lines.

If that image was part of a star-trail i bet you would see even more stars.

Similarly, increaing the gamma in image processing can be a very powerful
tool too. It allows the faint detail to be brought out without saturating
the brighter areas.

It's cool how these tools are becoming available to general use isn't
it?

Anyone who doesn't have photoshop already, here's a link to the GIMP
released under GPL (so it's free) runs on various platforms (inc.
windows) and can pretty much do all you need.

Have fun!
