Paul, I have shot with my Horizon 202 alongside a friend in Germany with a 35mm 360 degree camera (roundshot?) which was able to do unbelievable pictures. That was the good news.
With my Horizon, I have made plenty of pictures, but the success rate is provisional on not only the subject, but to a greater degree than normal, the quality of the light!
With the 360 degree or more camera, the quality of light or probably more correctly, the intensity of light one has to contend with in the arc that your exposure is obtained in, can greatly affect the printing difficulty/ease in a darkroom.
I often have to contend with a 5 stop range with my Horizon negatives, not a real problem, but a bit fiddly in the darkroom.
When I saw the negatives that my friend had with the 360 degree pictures it really opened my eyes to the possibilities but also to the obstacles needing to be addressed with this kind of picture.
The situation we took pictures in was ideal for his camera, good for mine as well. We were in Stuttgart near the Hauptbanhoff or main railway station, there is a square surrounded by buildings, not high rise. Standing in the centre of this square and waiting for the sun to go behind a cloud to expose for near perfect even light conditions.
We did this for I think three exposures, maybe four. On one of the exposures the sun started to come out of the cloud cover and the resultant neg density change made for interesting darkroom work, to say the least.
I printed them using a 4x5 enlarger and the quality of the enlargements, rather interestingly, were almost identical to the Horizon prints when the prints were placed side by side.
We used 12x16" paper and enlarged the film so that we had 200mm (8") on the vertical side of the picture. This meant that the Horizon pictures could be done in one piece on a sheet of 16" wide paper and the 360 pictures were done in segments.
I use a Schneider Componon S 105 for the Horizon negs in a special home made carrier and did the longer negs section by section in the same carrier.
Laid out on the dining room table or the floor with correct alignment, they look stunning.
The major difference between the two cameras is that with the Horizon I can make (with great care) continuous or 360 degree pictures as an end product, but with a camera that is capable of longer film sweeps which are adjustable to the required degree of sweep, that would be the bees knees!
