Clients often ask " What is that?" I explain that it's a flash meter and one of my favorite and most important piece of #PhotoStudio equipment. It measures both incident light and flash output, giving me the exact exposure to 1/10 of a stop, and lets me check lighting ratios (Highlight vs. Shadow side of the face). I have three of these, this one is the oldest and my favorite. The newer ones boast a touch screen and let you change the colour of the LCD screen.... and other silly features you never use.
