Another buyer mentions that it’s easy to adjust the portable backdrop stand and that it’s perfect for light-weight backdrops. He highly recommends it as one of the best background stands available. However, a couple of users have noted that the product is flimsy and breaks because the plastic is of poor quality. Some also complain that they received a damaged unit.
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!

The fill light for this shoot is also a Profoto D1 1,000W strobe in a Westcott Apollo Orb, which is camera right and with the light sitting about waist height. This light is also pulled back a bit further than the main to give a wider spill. Since I am using my lights to do two jobs, lighting the subject and the background, I am not gridding and instead placing them so that one edge of the modifier is pointing towards the edge of the seamless and the other is towards the subject.
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.

This is exactly what I needed to help my small photography business get off the ground even more! Great product! Very strong stands, and yes, as other reviewers stated, the backdrops are muslin and are very thin, just hang all three or a thicker material behind it and it's fine! I took some really nice Valentines Photographs of my children to test it out! I'm a very happy photographer right now! I did see a few complain about the light fixtures breaking on them, I think the case might be that they are over tighting the bulbs, don't, and you should be fine! I also read a few complain about everything not fitting back into the bag, I did not have this problem, everything fit back in just great! A very happy customer here!! I've attached some of the photographs I took using the black background.
