Default Cool Technique, figured I'd share it.

For any of you guys that have problems with Noise/Grain in your photos.

I've noticed shooting at higher ISO's at night, I've had problems with noise/grain. This one probably got rejected for noise about 5 times before I searched YouTube and found a tutorial. For Adobe CS versions of photoshop, I cant speak for Elements.

That technique yields a much better image than the usual noise filter, which is Gaussian blur. The reason there was so much noise, is I cranked the ISO to 3200, which in the D700(being a full frame sensor) is pretty clean. However I didn't pay attention to my meter, and underexposed the image. So when I went to fix the underexposure it left me with a very noisy image. I used this technique to fix it.

I also used it on my latest. I shot it at ISO 2500, it wasn't very grainy to begin with, but I wanted to make sure it was clean enough for the screeners taste.

You found a technique to improve your images and you want to share it?
And you opt to make your EXIF info available as well?!?!?

I find it oddly refreshing.

Thanks Wayne!

PS - The first image looks amazing for at ISO 3200. And you are right - better to be slightly overexposed then underexposed when noise is a high concern. Shooting at night I've found much less noise with much higher ISO's properly or even slightly overexposed then attempting to keep the ISO low and underexposing. Still, with a Canon 7D, I fear anything greater then 1600 unless there's really good light on the subject.

You're welcome, Mitch! I figured there's no point in keeping secrets, not really worried about anyone trying to copy me, or whatever reason people hide their EXIF data..

I had a D300 before(Nikons 7D equivalent or vice versa), and anything over ISO 1600 was a hot mess. Really wish that I had overexposed a little with that shot, it would have turned out a lot nicer.

Here's a few more High ISO examples..

ISO 3200
