Go Karting pics

Hi everybody,

I'm new to both smugmug and dgrin. I'm uploading my pics and one set is about a local karting competition where I was in August. Here is some pic:








You are welcome to report any comment/suggestion.

nice pics. I would crop the first a bit more.

I am not a fan of the shots from the back, that being said, the last is my favorite.

Your pictures are all technically "good" in focus, color, contrast etc... Now it is just a matter of making them better!

thanks! As regards the cropping, yes, I see most of the pics about this subject with the kart being "really close". Here is a trial:

thanks a lot!

As regards making them better do you refer to PP or to the improvement of shooting tecniques?

I went through some old post and I found this that I really like for the motion blur effect:

That "effect" is just a slow shutter speed. Two quick comments before I get back to the kitchen to finish cooking for friends is to slow your shutter speed down some. The other is to get more separation with the backgrounds. The backgrounds are so in-focus that it distracts from the main subject, the kart. I'll post an example later this evening.

Its late but here's the links I promised that illustrate what I was saying:

Motion blur by a slow shutter speed. This takes a lot of practice:


Separation of background (shallow depth of field):

thank you Bill for your examples.

While I've being playing with DOF, I never trained the motion blur by slow shutter speed.

I guess that I'm supposed to "follow" the moving subject during the exposure time, isn't it? Not easy at all.

Can you share the exif of your first pic?

Thanks, Sergio

Correct that it's not easy, but probably not as difficult as you expect either. You do follow the subject during the exposure time. Practice this way: put your focus point on some easily identifiable part of the kart. Pan and try and keep the point on the same part of the kart as you pan. Now as you click the shutter and the mirror goes up and then down, do you see the focus point on the same part of the kart again? That is your eventual goal. This helps with longer lenses than shorter lenses, because then you can be further back from the kart. And if you are further back the angular rate of panning (how fast you are turning and panning) is slower.

That first shot was shutter priority, 1/100 second, f/13 at 200mm. Notice that even though f/13 is a huge amount of depth of field, since your camera is moving the background will be very blurry.
