Yes... usually I scan to check how the entire image looks like.

But, if instead of test strips I cut a strip on the size of the negative and make some contact prints, with different time exposure on the same strip, so I can see the whole image and check what time expesure are the best on different areas for burning and dodging? Sounds a better idea? (by the way, I print from 35mm and 6x7 frame negatives).
