If you own an old analog camera without a light meter like me (Mehrdad), you might be looking for a little helper here and there to measure the correct exposure. There are many very good devices on the market. From handheld exposure meters to app solutions, but also very practical small clip-on exposure meters.
The Chinese manufacturer DOOMO (https://www.doomomade.com/) has two of these little helpers on the market. I want to share with you my opinion about the small DOOMO Meter S in a video on our YouTube channel.
Enjoy the video.
