Tech Day is mostly for lighting and sound.
Set is (you hope) nearly finished. (Or maybe it's not.) And Tech - or Technical Rehearsal - is a day to push scenic elements around, to roll wagons, and slam doors and generally make sure that the physical elements of the production are working. Actors are there - their participation vital! - but they're usually bored out of their skulls at the stops and starts and sheer tedium of it all.
Meanwhile, it's wildly exciting verging on panicked for stage management and designers. Especially for sound and lighting. (Costume is madly finishing things for the costume parade and Dress rehearsals coming soon. Basically, you don't want costumes on stage yet: the paint isn't all dry.)
Here's what lighting was up to at yesterday's Tech for Echo Theater's production of Ruined.
I'm loving the colors glowing through the slats of Mama's Bar!
(Thanks to the eagle-eyed company members who spotted their neighbor's old fence out on the curb for the trash! Great weathered texture.) The rest of the set? Well, someday soon I'll actually have all the scenic painting done. Fingers crossed...
