Shooting heavy steel cabinets, vaults and steel doors for a local manufacturer proved to be my limit. That's around 60 products with two variations in a hot, humid, noisy, dusty factory environment that stalled my Nikon DSLR, slowed down the laptop and affected my circulation! My production assistant was heroic in Mark Lidio-thank you, sir, for not quitting on me when my gears did! Many, many, many lessons were learned even more. When I look back all I can say is "whew!"
