"Leaf roll, or leaf curl, is a physiologic distortion that may develop with periods of cool, rainy weather. It causes the lower leaves to roll upward and become thick and leathery. Leaf roll does not affect plant growth or fruit production and requires no treatment." From here:

"15. Q. What causes tomato leaves to curl?

A. The exact cause of tomato leaf roll is not fully known. Tomato leaf roll appears about the time of fruit setting. The leaflets of the older leaves on the lower half of the tomato plant roll upward. This gives the leaflets a cupped appearance with sometimes even the margins touching or overlapping. The overall growth of the plant does not seem to be greatly affected and yields are normal. This condition appears to be most common on staked and pruned plants. It occurs when excessive rainfall or overwatering keeps the soil too wet for too long. It is also related to intensive sunlight which causes carbohydrates to accumulate in the leaves. Some varieties of tomatoes are characteristically curled."

If there isn't any yellowing, browning, or other symptoms, Bobert, I'd go with the two links I glued on in this post.

The camera I was using before the fire was an Olympus Camedia nearly as old as yours, Bobert. It worked fine. There are a few advantages in getting yourself a shiny new camera (they know how to talk purty to the 'puter), but I'll be glad to work with you if you want to use your Olympus.
