In summary, the key factors to getting the backdrop and subject lit in a similar exposure zone is distance; The distance of the subject to the background and the distance of the light source to the subject. Decrease the distance of the subject to background and increase the distance of the main light to the subject to make this easier. The key factor for getting a soft and directional quality to the light is also distance, but it's the opposite. By getting the light closer to the subject, we can create a softer light with more directional qualities. Also remember that these qualities of the light are relative to the size of the light source. If you are using a smaller light source, you will need to get it in closer to hold those transitional values. If you are using a larger light source, you may be able to get your light further back and still hold those soft-light qualities. Also, if the examples and basic principles here make sense to you, you have kind of just learned the inverse square law!
Please keep your expectations realistic: this is a $30 backdrop that will be delivered to your door. This is not fancy. This isn't printed on the best of materials, but do you need it to be? If you're a professional photographer who has worked with backdrops that are $200 a pop, you shouldn't waste your time with this one. But if you're like me, just cutting my teeth out on this business, this is a fine investment that is fun and easy.
This is a durable and well made photography back drop. All stitching is tight with no loose threads. It includes 5 spring clamps for hanging, or it can be hung using the sewn in rod pockets. It's made of 100% cotton and is a nice weight without being too heavy. Overall I'm very happy with this backdrop and recommend it to anyone looking for a nice white one.
