here We’ve got a working prototype of the Digital Super 8 Cartridge that runs with the Raspberry Pi 3 in an external module with touch screen. Benefits of that solution is the high level of control of operating the Digital Super 8 Cartridge and its settings through the touch screen. Plus the additional real-time monitoring of what is being filmed (in B&W) is a plus.
source However the drawback is that the ‘filmtype viewing pane’ of the super 8 camera has to be knocked out of your camera in order to enable the USB connection from the cartridge to the external module.
site rencontres rasta Some people have suggested to us to try and fit all electronics into the cartridge. Clearly we had to find a smaller Single Board Computer than the Raspberry Pi. Ports and test with the NextThing Co. C.H.I.P. SBC failed as this single core ARM SBC is simply not powerful enough. Now our hopes are on the Orange Pi Zero, which sports a quad-core ARMv7 SOC in a tiny form factor. We have ported the software and the OPI Zero performs reasonably well. Great results for VGA and QHD resolutions. But we need to find optimisations in the code and push for the 720p to runs without dropping frames as well. Whether this will be at all possible we don’t know yet.
click Benefits of this solution is that the Digital Super 8 Cartridge can simply be dropped into your camera and you don’t have to work with external module or screen. However the cartridge will have to provide a few buttons and LEDs for powering on/off and controlling settings. Alternatively we are looking at using VNC to provide connection via WiFi to your smartphone where you can then see the desktop of the Digital Super 8 cartridge and control its settings.
see We are now waiting for the appropriate Lithium Polymer battery and boost/charge circuit and first need to get all the electronics really to fit within the cartridge. More to follow.
source We managed to encode the RAW Digital Super 8 images with S-Log (following Sony’s algorithm). Then processing those with simple S-curve and tweaking colors, saturation and brightness/contrast a bit leads to great results, as show below:

average cost of lamisil At dusk we shot the grapes growing in the garden. First part is dark at 200 ASA but we also tested the autogain function that increases the CMOS sensor gain as necessary, leading to better brightness. At the cost of noise in the images of course.
We decided to not color correct the images, just take the 12 bit RAW images (as always) and do the gamma correction. But leaving brightness, saturation, contrast, red, blue and green in their default state. Pretty pleasing results, filmed with the Nizo 481 macro lense at dusk.
During our last coding session we developed the ‘ConnectCam’ button. This button allows users to functionally re-connect the digital super 8 cartridge to the raspberry pi control unit.
This comes in handy in case the USB cable between control unit and cartridge gets accidentally disconnected or wasn’t connected before the control application was started. This will help users solve small issues that may lead to a ‘DS8 Cartridge not connected’ error messages in the application.
