We had our first test of the liquid light show yesterday and it went great. When filming it we started out just filming the projector screen but once we realised that some of the candle dyes were too pigmented to show up well on the projector screen we filmed the actually glass instead, but from the side to not block the projector.
Our setup was really simple but the overall effect was great, we decided not to film from the top down for this test because we wanted to compare how everything looked on camera vs on the actual projector.
Things to improve:
- The candle dyes were too pigmented so there's a few options to fix this, the first is getting a different dye, but someone online suggested thinning out the dyes with oil first before applying them to the plate. Our main problem was the black dots that were showing up on the screen instead of pigment so this will hopefully fix that problem.
- The projector brightness. We used an old projector found in the uni storage and it worked well, but the pigments would show up better and there would be more possibility of projecting from further away and in bigger spaces.
Future Plans
- I'd like to eventually try projecting this live at an event, and while the OHP is the classic way to do it, it's hard to transport and I'd need to buy my own more specialised one. Until that's possible I'll be trying out having a camera right above the plates and hooking it up to a portable digital projector with an HDMI cable.
- Next time we try this we'll also be using a micro lens and a kaleidoscope lens.
- Since we'll be filming it straight down and in better quality next time, I'll then be using that footage to try and achieve the mockups I made a few posts ago, to see how combining animation and live action will work.
- I'll also be testing how projecting this on people and movement close up reads on camera.
