Question: What would be a good way to position three or all four umbrellas for a portrait of  single person?
Document: I bought this kit because it was inexpensive and had decent reviews. It turned out to be one of the nicests finds I have had to date. I needed to do a few photo shoots for the holidays and decided I would buy a &#34;disposable&#34; studio. Something cheap that would last 4 or 5 shoots. Boy, was I wrong (in a good way)! The kit has a very professional-like quality to it, and, so far, seems very durable.
The stand are not as stable at we would have like. However, for the price, it is a good buy because of the amount of items included. It does the work
I doubt you would intentionally select any individual component in this set "on purpose." When it's a choice between plastic or metal, its plastic. When metal must be used it's aluminum instead of brass. Back to the plastic, it's as thin as practical. Same goes for the metal pieces. For example, you need to handle the 33" umbrellas (they're that small) with care and I would worry that the stand legs would collapse if I put sandbags on them.
This is a good set for understanding light and how it will look. This is a good teaching tool and comes with everything you need to get a VERY BASIC set up going. If you are serious at all about photography I would look elsewhere. But if you want to understand light and are just about basics, than this light work out for you.
Some minor complaints:the frame is wider than the provided backdrops, and the fastening bolts don't tighten up enough for the tripod feet or the umbrellas, but setting those complaints aside, I have been able to take some very excellent portrait shots using the chromakey background. These photos have gotten a lot of positive compliments.Note to complaints about how thin the muslin material is:  hang one of the other sheets behind your backdrop. Problem solved.
Pros - 1) Lots of Stands and Umbrellas, 2) three backdrop colors.Cons- 1) Umbrellas are pretty frail. 2)The bulb sockets are all cheap plastic. 3) The muslin materials is SUPER thin and wrinkle ridiculously easily. 4) The lights are EXTREMELY week. 5) All 4 lights on at the same time is barely enough to properly light a scene in front of a white backdrop. 6) One of the knobs on The backdrop stand broke on me (more cheap plastic).
Carrying case is a little on the cheap side for the stitching so don't expect to use the handles to carry it, but other than that you are getting what you pay for. It is very easy to assemble. I am not too pleased with the brightness but opted for more hardware than brighter lights, other backdrop sets included brighter bulbs but took away light stands and umbrellas. I figured if I needed brighter lights it was easier to just purchase brighter bulbs.
It's a great deal. However I ended up buying a bigger background because the ones that come are literally half the size of the width of the poles. Also the umbrellas are very cheaply made. If it falls over they bend easily. Also the small knob to secure the actual umbrella pole to the stand keeps popping off. The actual inner screw pulled out as I was tightening it to secure it. I beleive the light bulbs are just basic but they work.
I love this kit! I sometimes use the green back drop if I'm doing any photoshopping, but I always use the other 2. The lights are perfect. I usually turn the room lights off and just leave the umbrella lights on. It makes my pictures look more dramatic. I highly recommend this kit to anyone either starting out in photography or already experienced. I use my remote strobe light in one of the umbrellas, which is great!
When I first opened this product, it looked really great! It came way sooner than I expected, especially since I live in Hawaii!! I was so happy about that. But when I took things out to put together, one of the T screws? (When you open the stand and turn the Tscrews it tightens it so it won't move) Fell out! The whole thing. The little nut that is in it  was not properly placed in.
Answer: It depends on how much light you need. I usually position the black on3s ouside and the white ones I uusefor softer light in the middle. U need to make sure to move em depending on the pose and were the persons facebis
