Been doing a bunch this summer, most of it with LED. I saw one show I had out, which had been utilizing SMD based High Res LED go to a different, multiple bulb type after a layoff... And I was disappointed. Blacks got crushed, banding was evident, and color reproduction suffered. It WAS cheaper. Ah the constant battle between what we want, and what we can get by with.
Flipside, working on a new show with a low res display. This was an SMD based pixel though, and despite the pitch distribution, rezzy looked great, color reproduction was awesome. Nothing looked posterized. And man was it bright. Led me to really weigh in my mind whether pixel pitch is primary, or quality of LED ?
Random musings this rainy summer day.
