I have an assignment to shot some frescoes in a low-light church. The church is rather small and it has scaffolds (bars) inside which are rather close to the paintings. So, most probably I need to have an UWA lens raked somewhere at 16-20 mm.
There is electricity somewhere there but I'm quite reserved that I can mount a full-fledged studio inside.
Thanks in advance for any tips.
PS: The camera will be a Canon 5D Mark III and I would preffer to shoot in the available light.
