Camera board • RaspberryPi Camera Module3 Close-up Issues

Hi, I'm using a translator, so this might be strange.


I am trying to do close-up photography using a RaspberryPi5 and Camera Module3.

However, you need to get closer to the face to get it in focus (10cm or less), otherwise it will only focus on the nose, leaving the cheeks and eyebrows blurry.

I changed the focus to Manual and also tried setting the coordinates using AfWindows, but it's the same.

Doesn't AfWindows focus on the coordinates I specify?

Or is there another way to focus?

Then, when I fire up Flash like DigitalCamera and use switch_mode_and_capture_image to get the photo, the photo is only bright in the center and dark on top and bottom (with clear boundaries), even though I timed the flash and capture because of the rolling shutter(?).

1. get no closer than 10 cm to the face so that the nose and cheeks are in focus at the same time.

2. when shooting with flash, you will see dark areas instead of overall brightness due to rolling shutter (?) (like the waves you see when shooting TV with a camera).


Any good suggestions for 1 and 2?

Thank you for reading.
