What is Fulldome?
![Page 20: @Bristol Data Dome workshop - NSC Creative](https://reader035.fdocuments.in/reader035/viewer/2022070521/58f9a8c31a28aba5278b45b9/html5/thumbnails/20.jpg)

The technolgy and configuration is mostly irrelevant to content producers
Most planeterium domes are 360 x 180Uni-directional seatingAverage tilt of 15 degressAverage resoloution for 15m+ domes 2.5k-”4k”
No-one knows the exact numbers of digital domesEstimated to be over 1200 internationally75% of these are smaller, under 2k resoloution and mostly portable.
![Page 25: @Bristol Data Dome workshop - NSC Creative](https://reader035.fdocuments.in/reader035/viewer/2022070521/58f9a8c31a28aba5278b45b9/html5/thumbnails/25.jpg)
Never assume any standard in the dome world! If making a piece for a specific dome get the specs first

Technical challenges
4096x4096 pixels @30fps8x more pixels than HD content
40x more pixels than regular DVD
The resolution of the domes is growing 8k, 16k...

The first rule of Fulldome is...there are (hardly any) Fulldome rules yet
![Page 36: @Bristol Data Dome workshop - NSC Creative](https://reader035.fdocuments.in/reader035/viewer/2022070521/58f9a8c31a28aba5278b45b9/html5/thumbnails/36.jpg)
Traditional techniques don’t work as expected
New film language required
“domography“
![Page 37: @Bristol Data Dome workshop - NSC Creative](https://reader035.fdocuments.in/reader035/viewer/2022070521/58f9a8c31a28aba5278b45b9/html5/thumbnails/37.jpg)
Analyse, learn from others Lots of previews on FDDB.org
![Page 38: @Bristol Data Dome workshop - NSC Creative](https://reader035.fdocuments.in/reader035/viewer/2022070521/58f9a8c31a28aba5278b45b9/html5/thumbnails/38.jpg)
Camera Movements
Start slow
You are moving the audience
Things appear faster on the dome than on screen
Slow things down
![Page 39: @Bristol Data Dome workshop - NSC Creative](https://reader035.fdocuments.in/reader035/viewer/2022070521/58f9a8c31a28aba5278b45b9/html5/thumbnails/39.jpg)
Not all Fulldome display systems are created equal!Avoid blackAvoid whiteAvoid blueGenerally avoid solid colours
Avoid subtlety!
Avoid forcing people to dislocate their neck for long periods!
![Page 40: @Bristol Data Dome workshop - NSC Creative](https://reader035.fdocuments.in/reader035/viewer/2022070521/58f9a8c31a28aba5278b45b9/html5/thumbnails/40.jpg)
Editing
Cutting is possible but has a different effect
Keep the flow
Dissolves can help, instead of 1 second try 3
![Page 41: @Bristol Data Dome workshop - NSC Creative](https://reader035.fdocuments.in/reader035/viewer/2022070521/58f9a8c31a28aba5278b45b9/html5/thumbnails/41.jpg)
Keeping focus vs exploring the frame
![Page 42: @Bristol Data Dome workshop - NSC Creative](https://reader035.fdocuments.in/reader035/viewer/2022070521/58f9a8c31a28aba5278b45b9/html5/thumbnails/42.jpg)
Characters
Hard to get right
Even harder in a dome
![Page 43: @Bristol Data Dome workshop - NSC Creative](https://reader035.fdocuments.in/reader035/viewer/2022070521/58f9a8c31a28aba5278b45b9/html5/thumbnails/43.jpg)
No-one can read on a rollercoaster
![Page 44: @Bristol Data Dome workshop - NSC Creative](https://reader035.fdocuments.in/reader035/viewer/2022070521/58f9a8c31a28aba5278b45b9/html5/thumbnails/44.jpg)
Balance between visual / music / narration
![Page 45: @Bristol Data Dome workshop - NSC Creative](https://reader035.fdocuments.in/reader035/viewer/2022070521/58f9a8c31a28aba5278b45b9/html5/thumbnails/45.jpg)

Lots of other tools now coming due to VR pushThere are differences so important to test in a dome also

Camera Rigs Can be cumbersome More software supported
Lens Shaders Quick and easy Straight to the dome

Don’t forget the audio!
5.1 surround sound is almost a standard but each dome has unique characteristics making mixing challenging
3D spatial sound is one of the next big things in dome creatively but very few systems in the world at the moment
Dolby ATMOS, Isono, Wavefield Synthesis, Object Based Audio

BRAIN SHEAR
The DISPARITY between what the brain SHOULD be seeing and what it’s ACTUALLY seeing is what causes PAIN.
Divergence - When your eyes move outwardsVertical Disparity - Things not matching upAccommodation - Fast changes in stereo depth

Single camera vs multi camera vs budget
