A user also mentions that the frame feels slightly flimsy, but he hasn’t had any problems with it. He adds that he is satisfied with its performance so far and that the carrying bag is a nice bonus. However, one customer complains that the product’s measurements are not correct and that it’s not strong enough to hold the vinyl in place without dipping.
As with lighting systems and camera equipment, backdrops require some kind of support to keep them in place. Background supports can be simple or sophisticated systems. The simple ones are easy to set up and break down and are well suited for location work, while sophisticated, permanent studio systems can hold multiple backgrounds that can be raised or lowered either manually or at the flip of a switch.
What this tells us is that the further away the light source is from the subject and backdrop, the more likely we are to get an equal exposure from one to the other. The quality of the light source can also change with distance. You will notice that as the light gets further away it becomes a harder light with less transitional values. Also, if the subject appears to be further away from the backdrop in the last image, it's due to me needing to use a shorter focal length (zoom out) to avoid getting the softbox in the shot. The shorter focal length exaggerates perspective.
The Julius Studio background curtain set features an aluminum alloy construction to ensure durability and portability, and photo clams made of synthetic nylon to provide a strong grip and prevent the canvas from slipping out. Another great thing is that it’s adjustable in width (5-10.3 ft) and height (2.6 -7.5 ft). In addition to this, the set includes quality sandbags for stability.
One of the advantages of using a chroma key background is that it can shorten production time by doing away with the need to change from one background to another. This kind of photo backdrop allows the photographer to freely take pictures without thinking of what background will best fit the image, as they can decide on that part later in the post-processing stage.

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!
