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!
We used this backdrop for an at-home photo shoot with a newborn. It worked great for us, the only downside is that it is folded when it comes and came with instructions to get the creases out adding some more work than just opening the package and taking pictures. Regardless, it flattened perfectly fine in about 10 minutes and we’ll be using it again so it was definitely worth it for the price and effort.
For a dramatic or edgy appearance, go with low-key lighting. Low-key lighting also focuses attention onto your subject by surrounding them in shadows instead of light. To do this, you want to ensure that your solid black backdrop is at least 3 stops darker than the light on your subject. With low-key lighting, you also need to ensure that none of the light from your subject is hitting your backdrop. Grids and flag are very helpful for this.
Last is the Julius Studio, which is another crossbar set up that spans up to 10 ft. Like the others, this one also comes with a carry bag and the necessary clamps for securing your backdrop of choice. Also, like the others, this one is made of lightweight tubing that makes it easy to carry. Lastly, while users said this was easy to set up and use, they recommend using sandbags or some other type of weight to keep the system secure due to the light weight of the tubing.
The fabric has a slight odor similar to vinegar and evaporated milk but airs out if you leave it unfolded a few days. The fabric, as expected, is lightweight but decent quality cotton. By definition Muslin is lightweight cotton cloth and, yep, it's thin so a backing layer is necessary if used against a bright light or window (e.g., my uploaded image). It ... full review
If you do many in-studio portrait sessions, you probably have a lot of space set aside for background materials, props, and supports. Add to your stash with canvas backdrops for photography, and selections made of durable, low-maintenance materials, such as cotton and wrinkle-resistant polyester. Several backgrounds come on rolls so you can mount them to autopoles and smoothly swap out designs between poses. Seamless paper works particularly well for everyday needs, as you can roll sheets out to the desired length and then reuse or trim away pieces for easy recycling. Muslin photo and video backdrops feature non-reflective surfaces that diffuse light more naturally, which can help keep the focus on your subject. If you prefer materials that allow for fast and efficient cleanup, vinyl and PVC backgrounds are a solid choice, especially when you use them in potentially messy situations involving pets, babies, and toddlers.
