Bruce, thanks for the advice, but I am an amateur at best. Not worried about all that stuff. My question is driven by (1) the comments below and (2) I just had some prints done for the first time at Costco. About 70% came out exactly as they appeared on the monitor, while the other 30% had a little different tint and were overexposed if shot duing the day/underexposed night shots.

As you can see, just an amateur and this is only a hobby at best for me, so I am not ultra obsessive about it. I just figure with the amount of time I spend trackside, may as well invest a little more money in getting the colors right but just need general advice. Thanks again.
