As mentioned in the thread about buying CdS sensors (https://kyp.hauslendale.com/classics/forum/messages/2/18472.html) I have started a longer write-up on CdS meters. If any one of you is interested in this topic, I'd love to hear some feedback, before I proceed further - I'm just not sure if it is of any use, and if it is understandable - English isn't my native language, leave alone all the problems of structuring one's thoughts. There are 9 pages right now, as free time allows I'd proceed further - finish the thing on "mercury battery" type meters and start about bridge circuits, light metering "types" and then discuss adjustments. The final conclusion I'm aiming at is adjusting light meters in one shot. I have managed to adjust my Gossen Lunasix 3 and a Praktica meter in one shot, by taking some measurements, computing necessary pot values and setting them to the computed values. Both meters were dead on (to better than 1/3 stop throughout full range, I have no better reference to check against) afterward. I'd like to put down the theory needed to do it in writing. The PDF can be found here: http://lwow.home.pl/photoblog/index.php/on-cds-meters/ The linked page is going to be updated as the PDF file is revised. Marek |
