Sorry I'm so slow getting back to you. What kind of software do you edit with? You should be able to zoom all the way in (where one pixel of image file equals one pixel on your monitor), then drag a box across the image and use a crop function. That would be a 100% crop, and it would give us a close up view of the grain.

But, I think you'll be happier just using a slower film. For high contrast stuff like this, print film will give you more room for error, and Reala would probably produce very nice results. But if you're brave, you might just pull off something really cool with Velvia. Be sure to bracket if you try. Good luck! :thumbsup:
