With film, you get grain, with digital, you get pixel i think. For film, grain is supposed to be there.
I would suggest popping a fresh roll as the poster above me recommends, and later on sending it to Konota at Peninsula area for developing and scan to CD. I have tried their services among several on the island and find that they provide the most consistent results of all. Hope it helps.
But if you can get your own scanner, like a canoscan 8800f or a v500-600, that would be so much better, as you would have more control over your scans. But then again, that's a whole different ball game altogether.
Most importantly, have fun!
