Again, these pics were shot with a Sigma 28-70/f2.8 EX at an indoor event. I'll be shooting the local indoor football team in this same arena in a couple of months and want to shoot as much action as I can before the "paid" gig!

Any comments/suggestion would be grealy appreciated.

Very good captures. Looks like you were able to make the best of the available light while still getting a decent shutter speed. Well done.

Thanks, slejhammer.

Looking back at the pics, I wish I'd have tried slowing down the shutter a little more to get more motion blur on the wheels. I was so stuck on keeping the lens wide open at 2.8 that I didn't think about other options.

Nice shots,

i agree a bit of blur on the wheels could be good, but you can always add that on the computer later.

I have a couple of questions

1) Were these with a 10D?

2) What ISO speed?

3) Are they full frame or a crop?

The reason I ask is that they are among the first pics that i have seen that could be significantly better than my d30 can do - so I may finally decide to buy a 10d.

Thanks

Mark,

These pics were shot with the 10d at ISO 800. I did crop them...in PS7 I used the rectangular marquee tool and with the fixed aspect ratio cropped them to 8x10 (or 10x8). There really wasn't that much that was cropped out, but I wanted the finished size to be 8x10.

To be quite honest, I'm a little uncertain about cropping. I understand how to do it, but I've seen people on these forums ask if something was a "100% crop" and I'm not exactly sure what they mean. I'm also not sure if cropping these to 8x10 is taking away from the quality, which I hope isn't the case. Any cropping suggestions you could offer would be greatly appreciated.

Also, I'd highly recommend the 10d, but haven't shot the d30 so I have no specific point of reference for my suggestions. I did look closely at the d30 and 60 and just didn't feel comfortable enough taking that plunge until the 10d came out. I'm glad I made the move.

Thanks for the info. I really must make my mind up soon!

Cropping is a simple process - it just means removing parts of the picture that you do not want.

It does not really relate directly to print size or quality, except that if you crop an image down a lot then you have fewer pixels of information.

This means that if you print the remaining (cropped) image on a large size piece of paper then you are spreading out the remaining pixels more.

This may or may not still be an acceptable quality for the purpose you have in mind.
