Question regarding the camera and exposure

Hi, Since the aperture is fixed the only 2 parameters I can change are .iso , and .shutter_speed . However I have to let the camera do a warmup for 2 seconds calling start_preview() . And it is then changing the analog and digital gain. But since every warmup changes the analog and digital gain acco...

Re: Restoring Access to a hacked rpi

Yes I will format the SD card, I just wanted to get access to the ssh logs, the python script is just a while loop that checks what time it is and triggers my camera, not really important^^. I found a way of resetting the admin password, didn't have time to do it yet (just got back) I'm amazed of ho...

Re: setting the same setting for several camera

Code: Select all

It all depends how much you are willing to code.
As much as it takes :)

Allright I'm going to read the documentation of this thing, thanks :D

Re: setting the same setting for several camera

I will have to experiment but I don't thing so.

I have to trigger the 21 cameras at the same time (with less than 1ms difference), I planned to do this using a pythong script that looked at a GPIO pin.

I'm pretty sure calling raspistill will introduce a variable delay

setting the same setting for several camera

Hi, I wanted to do a 21 camera face 3d scanner (already did one with some consumer grade camera). The problem I had before was that I need the same white balance, shutter time, iso and aperture opening on all pictures to get the best possible 3d scan. This was however not possible because those low ...

Re: cannot ssh into my raspberry pi zero W

No I was reffering to 'ssh -4'
raspberry.local is not found but that is normal since I renamed the hostname to rpcam1
using 192.168.1.35 or pi@192.168.1.35 does the same error

Re: Can I make PWM with GPIO

Why would it works badly? what is special about this library?

Is there a maximum speed for the GPIO before they start to behave erraticly? for example wait 100ms minimum before re-changing a GPIO state?
