David K,
The last photograph is the one that sold, twice now.
Once in a B&W enlarged to 5 feet by 7.5 feet. and installed above a living room so the looking up is actually looking up. The photo is by the client just after installation before the lights were adjusted.
A second sale was in color 24″x36″ is installed in an office in San Francisco.
I might be doing a longer report on how to print and frame photographs to 5 foot by 7.5 foot size sometime, if anyone is interested. It is an always technical framing challenge, but the S2 allows that kind of enlargement, which motived me to purchase it in the first place.
