Sure this was handheld, it became very blurred.

HOWEVER, I think add a very certain mood to this shot. Somehow creepy...

Peter, what is the purpose of applying the blur to CH A and B?

Klaus:
Yes, I stopped at an intersection to let wife get in one side of car and took the picture out of my window on the other. My old car is not a very steady platform at the best of times .

Ohenry:
I got this method of sharpening an image by applying unsharp to the L channel and gausian blur to the A&B channels from a photoshop course I took a couple of years ago. I remember the how but not the why.

<bad guess>
I think what it is supposed to do is sharpen the edges of the luminiscence channel. I guessing the slight blur on the color channels mixes them together and evens them out a bit.

I understand that unsharp mask in the L channel allows sharpening without causing color tone shifts. I'm just not sure what blurring the A/B channels does. Maybe someone here knows. If not, I'll ask that question in my Photoshop group discussion area. In fact, I may just go ahead and do that anyway

I like that shot, Peter. It is pretty eerie looking. By the way Peter, I need to thank you for your suggestion a while back about the Photobucket site. I love it. I've used it ever since.

I guess the first shot was a luckey accident.
Have not been able to handhold another night image and come up with anyting even remotely recognizable.

It reduces noise.

Thanks Barbara. I had found that out later and then remembered reading about that in one of my books. I use NeatImage and therefore had little need for that method and, like so many methods I've learned yet not used frequently, soon forgotten.

I forget easily too, and I finally got so thoroughly disgusted with myself that I made a little notebook just for Photoshop where I write up the instructions for doing things I absolutely do NOT want to forget how to do. Now the problem is finding the notebook beneath the heaps that grow on the desk.
