01 - Multi-camera control & triggering
Sept 14th, 2021
Xangle Camera Server test using two Sony ZV-E10 cameras. Triggering is made by USB. I forgot to mention that what I have on my finger is my usual powerpoint presenter which I repurposed into a wireless camera trigger.
02 - Real-time light-painting
Sept 14th, 2021
This is a real-time light-painting demo leveraging the “Streaming” mode of the two Sony ZV-E10 cameras. This is all made by USB with no capture card. Created using our Virtual.ink software.
The camera on the left side is responsible of capturing the light-painting (iso 100) while the camera on the right side captures the dancer (iso 800). Virtual.ink handles the light-painting traces. There is no special effect added to this. It’s a simple light accumulation of what’s capture by the camera.
It's the first time we're able to do this kind of work (dual mode) without using any capture cards (inogeni, camlink...). The resolution is limited to 720p (Sony’s limitation), but it looks quite amazing anyhow.
03 - Trigger precision test
Oct 10th, 2021
Xangle Camera Server test using five Sony ZV-1 cameras. As far as trigger accuracy is concerned, no significant difference have been noticed between the ZV-1 and the a6400.
Left: constant light, self triggered via a wireless powerpoint presenter. Signal is sent by usb to all cameras. Most of my constant-light shots by usb were a tiny bit shaky but usable
Center: one speedlight triggered via the 6th camera on sacrifice mode (triggered half way during the exposure). Shutter speed is at 1/60s, which is exactly what we’re aiming for. This is the best way to freeze the subject, no matter the triggering type
Right: constant light, self triggered via a wireless radio triggered connected to a trigger box (Esper), using the multi-port dual usb cable from Esper. This is the most accurate way to trigger these cameras using constant light, although I still got some glitches on a fast moving subject

Additional notes
It is an absolute joy to work with these light-weight cameras where a single cable is required. The setup I used was 6 cameras on a powered hub, connected to a single Surface Book
Trigger accuracy by usb is perfect for any photogrammetry rigs (meets the 1/60s accuracy requirement)
Trigger accuracy by usb is not good enough for a photobooth where the subject needs to be frozen, but this is something that can easily be fixed by using a multi-port cable connected to either an Esper Trigger box or an Xangle Board
The ZV-1 has direct access to f-stop and iso values (as opposed to step increment on the a6400). This makes the ZV-1 much more efficient to change settings. Unfortunately, the shutter-speed is still step-increment (very slow to change)
