"The display of an image on an arbitrarily complex surface"
The display of an image on an arbitrarily complex surface or Projection Mapping is the creative medium where video projectors are used to bring everyday objects to life. Normally, video projectors are used to display images on flat, white screens (e.g. watching a movie, viewing a PowerPoint). Projection mapping displays images on non-flat (possibly non-white) surfaces.
Seems like projection mapping has exploded into the consciousness of artists and advertisers everywhere over the last 3 years and practically every landmark building in the world is getting a night time make-over. Not that I'm complaining, I love having the opportunity to go shooting at night....even in Melbourne.
These were taken recently as part of White Night Melbourne.
But look further back than the last 3 years and you may find that the history of projection mapping dates back longer than you may imagine and there is a Disney link.
Most of us here will have gotten on to the Haunted Mansion ride at some time or another.
Yes! The first known instance of projection onto a non-flat surface dates back to the 1969 opening of the Haunted Mansion ride in
Disneyland. The dark ride featured a number of interesting optical illusions, including a disembodied head, Madame Leota....
....and 5 singing busts, the 'Grim Grinning Ghosts', singing the theme song of the ride. These were accomplished by filming head-shots of the singers (with 16 mm film) and then projecting this film onto busts of their faces.
Okay. I took these from WDW later on from this chronological point in time but it so completely fits in this point of the TR right now! You might see them again at some stage.
Disney not only pioneered the technology of projection mapping, they also have the earliest patent in the space. Entitled "Apparatus and method for projection upon a three-dimensional object", it essentially describes a system for digitally painting an image onto 'a countoured, three-dimensional object'.
By using specialized software, a two- or three-dimensional object is spatially mapped on the virtual program which mimics the real environment it is to be projected on. The software can interact with a projector to fit any desired image onto the surface of that object. This technique is used by artists and advertisers alike who can add extra dimensions, optical illusions, and notions of movement onto previously static objects. The video is commonly combined with, or triggered by, audio to create an audio-visual narrative.
Phew! That's a lot of technical mumbo jumbo to describe here. But yall know where I'm heading, right?
After the WitW Dissers finished enjoying MSEP, we realised that the timing could work out great to go catch the fireworks. So, we headed towards the hub. Or at least we tried to. Sunday night at MK and getting out of Adventureland and heading to the hub, we hit the slow-moving human traffic jam.
We made it to this particular corner in time to catch bits of the Celebrate the Magic Castle Projection show.
Whilst it was all straight lines and angles from the position we had found ourselves to be for the Castle Projection show, we didn't think it would be a good place to view the fireworks from.
I know the others were having a bit of a discussion about where else to go. Contrary to appearances, the hub was packed and there was no way we would make it down to Main Street.
I played it two ways. I started to set up the tripod whilst I waited for a Fix-It Felix to let me know what the group consensus was going to be.
I could definitely hear some free-flow discussion going on behind me.
At this point, I was ready to move on. No doubt about it. I'd long come to the conclusion that this was not going to be a good spot for fireworks. We were too far twisted to the side of the castle to get a decent view.
I was pleased to find that the others had thought the same. One last snap and it was definitely time to move.
And I'm going to do a bit of photog speak here; so for those of you not interested, keep moving along. I think Leshaface asked for some information way back when and I had it in my mind to use these shots as an example.
For those of you without tripods, the pictures here from the Castle Projection show were taken 'hand-held'. Yes, I know I set up the tripod; but I didn't have time to change my settings on the camera.
So just like in a dark ride.....my ISO setting was pretty high; the aperture was opened wide and the time was set to get the right exposure.
For those of you wanting to try this but not wanting to shoot in manual mode, move your setting to Time setting (Tv mode).
You will want to set your camera to the highest ISO setting where the pictures aren't too grainy. For most cameras, this will be ISO 3200 (or ISO 1600 for some of the earlier, older dSLRs).
Next set your time to about 1/50 sec.
This mode will mean that the camera will calculate an the aperture setting to get the right exposure.
Take the picture and see how it looks. If it is too dark, set the time to 1/40 sec and try again.
If it is too bright, set the time higher (1/60 sec) and try again.
Happy shooting!
