Michael,
Speediest of recoveries to you! I, too, am currently in a 6-8 week recuperation from surgery for cancer in my arm (fibrosarcoma). 2nd time for this surgery in 5 years. Just letting you know that you will recover and be back to speed. Like you, I can't shoot as I'd like to, but it's a great chance to hone post-production and processing skills In LR & PS and catch up on older shoots that have been waiting for attention. Always an upside!
Best to you,
Steve Hargrove
