Robot, Imagica Make Live-Action/CG Project 'Luna'

“The anime studio Robot and video post-production company Imagica announced on Saturday that they have partnered to produce a next-generation media project titled Luna. The project combines live-action and CG images to create a modern retelling of the classic Japanese tale of Princess Kaguya. Production of the 17-minute project is expected to be completed at the beginning of September.

The project utilizes 8K resolution, the current highest resolution in digital imagery, and high-dynamic-range (HDR) imaging techniques. 8K resolution offers 16 times the pixels of current standard HD images.

The production envisions Luna as a ‘fusion of visual beauty and story’ and a 'visual representation of light.’ The project aims to weave a beautiful story by synthesizing 8K and HDR techniques with CG composite images and color grading.

Award-winning director Kazuma Ikeda (Servant X Service opening animation, Hero Bank ending animation) is helming the project. Kenya Hirata (SHINOBI - Heart Under Blade) is in charge of the script. Hirata previously wrote the script for the 2009 Oscar-winning short La Maison en Petits Cubes (Tsumiki no Ie) short, which Robot animated. He also scripted Boku wa Bousan. (I am a Monk), which won a Platinum Remi award in the Docu-Drama category at the WorldFest Houston International Film Festival this year.”

HDR, the Difference, and the Application possibilities.

Click on the images for more commentary.

HDR stands for High Dynamic Range. An HDR image stores a lot more color information than your average png or jpeg (which we refer to as LDR or Low Dynamic Range). In fact HDR is capable of storing colors both much brighter and much darker than any current monitor is capable of displaying.

In photography, HDR images are captured by taking multiple exposures (or brightnesses). This means areas that would normally be bloomed out white or in black shadows retain both their color and their detail. (The photos on the left are standard LDR images whereas the images on the right were made with HDR processing.)

Since there are currently no consumer grade HDR displays, I collapsed the HDR images into LDR images for the sake of comparison of color information and retained detail. Notice the sky in the sunset photo and the palm tree in the restaurant photo.


Now, Source Filmmaker is capable of outputting actual HDR files (as the engine itself is HDR capable) called PFM (Portable Floatmap) files. These are the same types of files used to create HDR skyboxes in the engine.

If you use HDR capable photo editing software like Photoshop to edit your renders, you can see some of the benefits in retained color information compared to a png like how the lightsaber turns red instead of grey. I use PFM files to add proper bloom to my renders since how SFM does it isn’t that great.

And since SFM uses HDR, things like motion blur are calculated more accurately to real life. So a lightsaber moving really fast, for example, would have an actual light trail if you’re willing to turn up your motion blur samples slightly.

No particles were used in either of these videos.

The lightsaber uses a red texture with a self-illumination tint value of 1000 which makes it bloom out brightly and leaves a much brighter motion blur, effectively giving it a motion trail at stock and slow shutter speeds.

I also have a video where I go completely overkill with the shutter speed for demonstration purposes.

There are many possibilities with HDR, even within SFM as it makes things like bokeh possible and faking long exposures of cars on a freeway.

For your consideration: the benefits of HDR.

Starry sky during a total lunar eclipse

The bright Full Moon is dramatically dimmed by the Earth shadow during a total lunar eclipse as shown in this HDR (High Dynamic Range) composite image. The moon size is slightly enlarged in the composite processing to cover the over-exposed moon in the background image. The eclipsed moon shines in red and is hosted by constellation Leo. Stars of Ursa Major (Big Bear) are also notable at top right in this wide-field view.
