We used one of the Logitech C920 webcams for our main camera this week to see if we could get good picture without the flicker.

  • {play 9:35}Feature: Studio D is a go, and we're working out how we can get a good broadband service. It looks like a wireless (or perhaps LTE) service will be the only option, but will require an antenna on the roof.

  • {play 14:00}Feature: Setting up a green screen studio for live broadcasting, video production or photography.
    • Unboxing a green screen kit from Tube Tape.
    • Our kit includes: Light stands, 24" soft boxes, diffuser panels and bulbs for 2x 5500k lights, a 10'x12' chromakey green muslin screen, and a stand for the drape.
    • Setting up our green screen on the stands, and the lighting softboxes.
    • Positioning the legs of the tripod stand to support the weight of our lights.
    • Some of the reasons we won't get a good key off our current setup: our studio is too small, making the lights and subjects much too close to the screen, and the screen itself needs to be ironed or steamed.
