Thanks for the many comments y'all.
RcWr, maybe I don't have to do two of thesame types of shot after eachother anymore, abit of variation can do good. But I didn't have much inspiration lately, and ofcourse I can make different shots, but I just thought this was a nice pic to post.
BTW desktops of both are coming, dunno know when I'm going to upload em though.
440: First I want to thank you for saying this it's the best looking frontal blur at GTP.
The answer is second:
I once saw Franz saying somewhere you should blur the road seperately, with noise. I didn't use noise on the aston but in the last pic I used it. For alittle bit of more realism. And, in fact when you look at cameras following cars in real life, at low perspective, the road moves faster ofcourse. And with these pics being low perspective I decided to blur the little walls close to the camera with the road. At like 100 pix moving. If I'm not satisfied then, I'll move 100 pixels again.
The rest doesn't have to be moving so fast, so I'll put that around 20-30 pix. I adjust the b/c before blurring, around 70 contrast and varying brightness. That's how simple it is. And excuse me for the long explanation because of my lack of english vocabulary.
