i just got a dslr one of the main issues that i hope to solve using this camera is grainy pictures taken at car shows indoors in dim light. WHAT IS THE BEST WAY TO REDUCE THIS GRAIN (DIGITAL NOISE)??? i generally shoot at an iso of 200.. what can i do to reduce noise??? (possibly by changing other settings such as aperture and exposure; and how should i change those settings to result in the best/well lit/ and clear image as possible with NO NOISE/GRAIN)??????
im open to any tips (using the factory flash on manual mode)

Any takers?
