Re: Raspberry Pi 4 Dual Monitors

The software update has fixed the issue for me sudo rpi-update I also now see how the layout can be tweaked by the positioning of the 2 displays, so that you can overlap or not, hence ignore my comment earlier regarding the interface, which now does exactly what it says on the tin. Even booting with...

Re: Raspberry Pi 4 Dual Monitors

No point looking for new monitors, it’s clearly a Pi issue that almost certainly can be solved once the foundation have seen this sort of feedback from us early adopters of the Pi4. Whilst we’ve all used different displays and tried different combinations, the actual issue experienced is the same, o...

Re: Anyone using motionEye?, best setting for stills

The software only stores a stills picture once a second by default. The FAQ has the answer on how to modify this. Here's a copy of the information. I suggest you read the manual and setup information and then alter at your own risk. "The default file name pattern used when creating pictures is %Y-%m...

Re: Turn night-time camera (noir-camera) camera to daylight camera

It's a physical filter in front of the imaging sensor, usually glass and a pale cyan in colour. It's purpose is to block certain wavelengths in the IR range from reaching the sensor. If you take apart an old broken camera / camcorder you'll find it inside every device. Although you'll probably destr...

Re: New 8MP Camera - Q&A thread

Tested my v2 camera with a PiZero this evening and can confirm that the focus is set very close compared to all my v1 camera modules. Some pictures of flowers and images taken at 'selfie' distances 1.0-1.5m very well focussed, but anything at a greater distance out of focus.

Tested today whilst the sun was out using an 850 IR filter. Gave a good IR effect but grainy image due to the ISO. I also noted that images had almost no colour cast using auto camera settings (virtually a B&W image). Odd picture did have a magenta tint when I tried a time lapse. The 850 filter is p...

Re: Camera exposure settings

I would say that what you have experienced applies to any form of digital imaging. Auto will operate over a range of light levels. Outside of this range then parameters will need adjustment. Hence why even the most complex of cameras don't always get the exposure spot on. Features such as backlight ...
