In the first place, what make you think that a P&S film cam can outperform your S45? SOmeone told you that or it had alread in your mind telling yourself that film is forever beating digital?
The fact is if you couldn't take a good pic using your S45, the problem is not purely from the cam, there are too many reasons to explain this...
My suggestion for you is to understand your cam, read the manual, show ppl your pic (here?) with your setting set, ppl here might be able to help you.
Frankly speaking, I think S45 is a good digicam indeed. And there is no way a $200 compact P&S cam can beat this baby in any way...
Sometimes, why ppl still prefer compact film cam cos they are easy to use but nowadays, the digicams in the market are too "powerful", they let you set the setting yourselves instead of setting by the camera's in-build computer. Thats y very ofter, ppl get blurred pic or under/over-exposed pic when they are using digicam and claim tat the cam is not as good as the compact film cam.
Just my 2 cents cos i see too many ppl cant take good pic using the advanced digicam whereas can deliver reasonable good pic when using compact P&S film cam,... simply because these ppl dont know their camera.
Hope you dun get offended.
