Black Spot?

[Raffles]

One of my Sheyenne tomato plants is developing black spots on yellowing leaves. Hopefully image is attached.

I'm thinking black spot.

There are some yellowing leaves on my other plants but not as much. I'm thinking too that this plant may have been a little more stressed as it is close to the path and the spots appeared after a jag of long, heavy, cool rains.

What thinks ye?

Most likely Septoria Leaf Spot since it spreads in moist humid conditions. The back spots may have gray centers and the yellow halo is typical which can be seen in the photo.
Black Spot is a different fungus that infects Roses and some other plants.

Thanks.

Next year I'm going to have to be better about prevention.
