My photography focuses on meals served onboard international business/first class travel. One of the challenges is to get lighting right; especially when I travel red-eyes, I often choose to have my meal mid-flight when lights are dimmed and am stuck with just a reading light. I thought about using a flash at 1/128th power, possibly with a diffuser.. What are your takes on this? Does anyone have any other ideas? Perhaps a very small flash I am unaware of (I was thinking, they have pocket-sized beamers nowadays.. are there any similar pocket-sized mini flashes? Unaware what to Google to find out..)? Any input is appreciated!!
