How to get a right exposure?
I've been playing around with my XSi for a while and I understand the basic of shutter speed, f/s and ISO, however when I'm taking objects in motion (fast or slow) I couldn't take a very sharp picture, somehow the pictures turn out blurry..

I tried to increase the shutter speed, but the picture turns out dark( not enough light) any solutions to this problem?..

Distance to subject is also very important..

Logical that with static objects like buildings if you will exclude camera shake by stable tripod/timer use - you will get sharp results even at 30 sec exposures (night)..

When shoting dynamic subjects use common sense - 1/125 for walking person1/500 or faster for flying bird, 1/2000 to freeze wings of insects..

Faster shutter speed - higher ISO needed, faster lens, additional light sources (flash)..

Some action photo situations are incredibly challenging. For example indoor sports where flash is not allowed, you will need combination of fast lens (<f2.8), and camera with good high ISO quality

Increase the ISO speed as it seems that you have reahed the maximum aperture. Or you are taking photos at f/16?VictorBucuresti, Romania

Thanks for the input, what I found is probably a combination between light exposure and camera shake. are there solutions for camera shake besides using a tripod?..

Right exposure is one that shows results you wanted to achieve..

You can make shot of race car with 1/2000 sec that will freeze motion of car, weels and make background look static..

You can also use panning technique following car movement with lens and making photo at 1/125. You will get sharp car, circular blur on weels, linear blurred background..

You can also make shot of came car by pre-fucusing at road stretch and making click at 1/60 when it passes - you will have static road/bystanders and completelly blurred speed effect of race car..

Read the book, "Exposure," I'm new to this too with an xti and I'm reading this book for the second time and every page in it improves my photos.Hank Greenblatt..

I agree, Understanding Exposure by Bryan Peterson is a good book, I have learned a lot from it. You could even buy it just as a collection of picture!.

You can get a monopod if you feel a tripod is too expensive and heavy. I plan on buying one in the future..

Good luck!..

For steadiness without any tripod, you can make a steading device. simply get a 1/4 x 20thread eyebolt as short as you can find. screw it into the base of the camera into it's tripod socket. tye a nylon rope say 1/4 or 3/8 ich diameter to it about 6 ft long. let it fall to the ground and stand on the rope, adjust length as needed to pull tight and yet hjave the correct handholding technique with the camera..

The results will be a steadier camera and images...
