I have beautiful tomato plants with lots of foliage but few tomatoes. The tomato plants are Brandywine. They have lots of foliage (very dense) and 6-ft tall. The plants are exposed to full sun but do not have many tomatoes and those tomatoes are shaded from the sun for part of the day. Will the tomatoes that are on the plants ripen without being exposed to direct sun?
Brandywine is notoriously a small producer.
I have had some years where my plant only grew 3 tomatoes.
I personally have stopped growing Brandywine varieties and have found many other heirlooms with nice size and delicious flavor that produces lots of fruit.
A personal favorite is Ananas Noir or Black Pineapple.
I like to plant tomatoes in full sun but a minimum of 6 hours will be sufficient.

Big plants, lots of flowers, no fruit. However, in the same garden, same soil, light and pollinators my plum and brandy wine are producing, while my German browns and Cherokees are not. The plants also don't seem to be getting as big as the plum type. Please advise.

Chance are the plants that are producing fruit are determent (ripens at the same time) and the others are indetermenant (ripens over a period of a few weeks.) Hit them all with an epson salt bath which aid in fruit development.
I live in the Pittsburgh Pa area and planted them in the middle of May. They have about a doz. small green tomatoes on each plant, but they are only 6-8 inches high. They look very healthy. I thought they grow fairly tall. Thanks Andy
Unfortunately, your photos did not come through.
This can happen from any number of stresses. Once proper care is provided, then you can begin to diagnose other factors such as disease.

The flowers are not fruit flowers. These are photos of the two. One is on a German Queen variety and the other is on a Pink Brandywine plant.
This is common in modern tomato cultivars. Sometimes, flowers will fuse together. This is what people that grow record-breaking fruit look for when knowing which tomatoes to keep on the plant.
