On CdS meters

Here: on CdS light meters v0.3.pdf you can find the most up-to-date version of my writeup on CdS meters.

This is work in progress, but I wanted to use this excerpt in a web discussion already.

I will update this post as new versions are available. PLEASE don’t link to the file directly. The link will break as soon as I update the file.

April 7th, 2010: initial release
April 10th, 2010: expanded part on mercury battery based meters
April 27th some updates, mostly diagrams, not much new work done

Enjoy,
Marek

    Hi Marek,
    Great article on the basics of light meters. This gives the theory behind the deceptively “simple” CDS meter. I have been looking for an article of this detail for some time. Congratulations on producing this so far. I can’t wait to see they rest.
    Best Regards

    Hi Marek,

    This is a great article. Do you think it is possible to add a CDS meter to a camera that doesn’t have one using parts from the CDS meter of a completely different camera?
    Your opinion on this would be greatly appreciated.

    Looking forward to updates on this article,
    – Jacob
