A quick test with good results
In July 2019 I had the opportunity to get some images from the new Theta-Z1 for testing. The images were taken on a sunny day with lots of direct sunlight to see how high the captured values are going to be in the HDRI.
- The Theta-S HDRI clipped at around a value of 3 in direct sunlight.
- The Theta-Z1 HDRI (created from the DNG-RAW brackets with PTGui) clipped around a value of 600.
- Comparing the specs of the Theta-Z1 to the Theta-S. The shutter can be set 4x quicker (1/25000 instead of 1/6400) and the aperture is three stops smaller (5.6 instead of 2.0).
The Theta-Z1 is a big improvement over the Theta-S. The RAW DNG stitching with PTGui is a good and fast workflow for this camera. It takes around two minutes to capture the images.
Compare this to a HDRI made with the Canon 7DMKII, ND filter and 7 exposures. The sun clipped here at around 30.000. It takes around 7 minutes to capture a full 360° panorama with my setup.
