As ever I left making the purchase of a California Sun-Bounce for a job I was working on until the last minute. A quick call to Calumet assured me that the product would arrive before the job date. It did and I was able to use the product on the job. The Sun-Bounce has really exceeded my expectations. It was an outside, sunny location for a car company with people and cars, so I needed to get some serious light into the shots. The throw on the CSB is amazing and given it's sturdy but really light weight aluminum frame the CSB is easy for an assistant to hold for long periods just in the right position. I went for the mid-sized as I think the large might just have too much of a 'sail' effect in breezy conditions.
