With this shape I went back to the drawing board and looked back at my previous models so see where I had been going with size, angles and general style. One element that I liked from my first prototype was the angular shapes. I didn't want to just recreate this so I developed it slightly and took some of the edges away. Also thinking about how this would look attached to the balloon, I didn't want it to be too small, so the size of this model is the same as the first which seemed the right scale.
I also liked the idea of having a block across the front/bottom of the device which would be a leather panel, either in the same colour as the camera body or a retro contrasting one. When looking at vinatge cameras and the first ever cameras they were all made of luxary materials until they were made commercially available worldwide. I liked this contrast of soft fabric and a processed hard one.
I've done quick variation sketches of this which will be in another post.
