Building an ESP32‑Based Incident Light Meter for Photography & Cinematography
Incident light meters are indispensable tools in photography and cinematography. They measure the light falling onto a subject rather than the light reflected from it, giving far more reliable exposure readings—especially in scenes with dark backgrounds, bright highlights, or high‑contrast lighting. Commercial incident meters cost anywhere from €200 to €500. That’s a lot for someone…

Samba shares not working, Windows Error 0x80070035
I already shared a solution to Windows Error 0x80070035 when opening network drives error here. However, apparently latest version of Windows 11 changes something again (sic!) and old solution is not guaranteed to work anymore.Hence, Windows Error 0x80070035 strikes again with a full force.Luckily, there is another solution that enables “Insecure guest logons” and makes…
