Well, thank you guys for all the comments!
And as I told you on my first post, that I will give some comments later, here they are:
Yes, this picture was taken with my S70, but I was far, so I cropped it (next time I crop the top hehe).
The exif will be:
Model: Canon PowerShot S70
Size: 3072x2304
Bytes: 3445693
Aperture: f/5.3
Focal Length: 20.6875mm (guess: 69mm in 35mm)
Exposure Time: 0.001s (1/1000)
JPEG Quality: 5
Flash: Flash did not fire
Exposure Bias: 0
DigitalZoomRatio: 3072/3072
SensingMethod: One-chip color sensor
ColorSpace: sRGB
As you can see, 1/1000 was to damn fast for this, but I can't get closer in this race. So what I did, was masked, cropped, then added the motion blur, and a little USM filter.
And I think that the result was very good (besides of the crop hehe).
This was a PS enhancement for this picture. May be because I was thrilled not to have a good one from that race. But next time I get on track I hope to be closer like when I go to a rally, were I'm improving a lot with slower speeds.
Later I will post some with slower speeds that are very good from another rally (without processing).
Thanks for all your comments!
