Erik Winquist – The Definitive Weta Digital Guide to IBL hdri capture
www.fxguide.com/fxfeatured/the-definitive-weta-digital-guide-to-ibl
Notes:
- Camera type: full frame with exposure bracketing and an 8mm circular fish eye lens.
- Bracketing: 7 exposures at 2 stops increments.
- Tripod: supporting 120 degrees locked offsets
- Camera angle: should point up 7.5 degrees for better sky or upper dome coverage.
- Camera focus: set and tape locked to manual
- Start shooting looking towards the sun direction with and without the ND3 filter; The other angles will not require the ND3 filter.
- Documenting shooting with a slate (measure distance to slate, day, location, camera info, camera temperature, camera position)
NOTE: The goal is to clean the initial individual brackets before or at merging time as much as possible.
This means:- keeping original shooting metadata
- de-fringing
- removing aberration (through camera lens data or automatically)
- at 32 bit
- in ACEScg (or ACES) wherever possible

Open Source OpenVDB Version 9.0.0 Available Now and Introduces GPU Support
First introduced in 2012, nowadays OpenVDB is commonly applied in simulation tools such as Houdini, EmberGen, Blender, and used in feature film production for creating realistic volumetric images. This format, however, lacks the GPUs support and can not be applied in games due to the considerable file size (on average at least a few Gigabytes) and computational effort required to render 3D volumes.
Volumetric data has numerous important applications in computer graphics and VFX production. It’s used for volume rendering, fluid simulation, fracture simulation, modeling with implicit surfaces, etc. However, this data is not so easy to work with. In most cases volumetric data is represented on spatially uniform, regular 3D grids. Although dense regular grids are convenient for several reasons, they have one major drawback – their memory footprint grows cubically with respect to grid resolution.
OpenVDB format, developed by DreamWorksAnimation, partially solves this issue by storing voxel data in a tree-like data structure that allows the creation of sparse volumes. The beauty behind this system is that it completely ignores empty cells, which drastically decreases memory and disk usage, simultaneously making the rendering of volumes much faster.

Kelly Boesch – Static and Toward The Light
https://www.kellyboeschdesign.com
I was working an album cover last night and got these really cool images in midjourney so made a video out of it. Animated using Pika. Song made using Suno Full version on my bandcamp. It’s called Static.

Mysterious animation wins best illusion of 2011 – Motion silencing illusion
The 2011 Best Illusion of the Year uses motion to render color changes invisible, and so reveals a quirk in our visual systems that is new to scientists.
https://en.wikipedia.org/wiki/Motion_silencing_illusion
“It is a really beautiful effect, revealing something about how our visual system works that we didn’t know before,” said Daniel Simons, a professor at the University of Illinois, Champaign-Urbana. Simons studies visual cognition, and did not work on this illusion. Before its creation, scientists didn’t know that motion had this effect on perception, Simons said.
A viewer stares at a speck at the center of a ring of colored dots, which continuously change color. When the ring begins to rotate around the speck, the color changes appear to stop. But this is an illusion. For some reason, the motion causes our visual system to ignore the color changes. (You can, however, see the color changes if you follow the rotating circles with your eyes.)
