Thank you, Mikel...I like it also, obviously. Initially, I though that 15s was way too long a shutter speed for what I wanted. But looking at it again, I think that maybe this image needs a re-cut, another and different run through Photoshop to enhance the streaking car lights.
I'm just back home and throught, what the heck, let's post some images on Challange. But re-sizing these and re-sizing again to get to the 150k was interesting and maybe educational also. I like a second final pass of sharpening and I was surprised at how much size a second pass added to the image size...so re-cut it again...lol
