How to use a hand light-meter?
I posted this question in the darkroom discussion group, but was told it was not the appropriate group to post, so I will try here in the film & labs section instead.
Film needs to be exposed properly for the best results, so I hope nobody here takes umbrage. As obtaining correct film exposure is of fundamental importance to provide good negatives, would a hand meter be a worth while investment instead of relying on the TTL metering of my 35mm SLR Camera that I use at the moment? I also use this to transfer readings across to my Mamiya RB67 medium format camera. What are the advantages and disadvantages of incident versus reflected measurements? I would like to know more about using a hand meter before parting with my money. I saw a Kenko KFM-2100 on-line, but it can be any other models and brands you can think of, as I am not sure what to buy. Please help and advise. |

writes I posted this question in the darkroom discussion group, but was told it was not the appropriate group to post, so I will try here in the film & labs section instead. I saw your original post and it made me smile. I've been lurking in that group for a year or so. It gets about one post a month which is quickly followed up by a reply stating that the original post was off topic for the group. I know that constant OT posts can be a pain in high volume groups but in near dead groups its not a big issue. You have to wonder if the reason the group is dead has something to do with the anal replies from the one or two remaining regulars. Anyway, I enjoyed your question. I'm still trying to work out if its worthwhile getting my own light meter repaired. Its a lovely old Weston Master V complete with invercone which I picked up for a few pounds. Unfortunately the selenium cell is just about dead and the cost of getting it replaced is approaching the cost of a modern lightmeter. -- Paul Giverin My Photos:- www.pbase.com/vendee |

Very generally, a handheld meter is more accurate than one built into the camera- very generally. A handheld meter might be easier to read and adjust than the TTL meter. I usually carry a meter with me-- I read the meter, look at the conditions, and set the exposure to what I thought it should be without the meter reading! A reflected measurement is an overall average reading. An incident measurement is more specific, and depending on circumstances may be more accurate. However, in some cases (a picture of the Grand Canyon?), an incident reading is difficult to impossible. Keep in mind that the meter wants whatever it measures to be 18% gray. If you are reading a snow scene, the meter will try to make the snow gray. As to specific models, you might want to consider a meter that can read electronic flash, or a spot meter (you look thru it and pick the spot you want to read); depending on the kind of shooting you do. A digital readout might be more rugged than a moving needle meter. Ken Hart |

O Dear,
I've missed Ansel Adams, see http://en.wikipedia.org/wiki/Zone_System This is a very good explanation about the theoretical background!

Kodak have a publication about light-meters and how to use them on their website which you might find useful.

This is only the case with a reflected light reading. The incident meter reading is independent of the reflectivity of the subject. However, the incident reading should, within the characteristics limits if the flim/sensor, enable the image to show brightness representative of the correct reflectivity of all parts of the subject, including those with 80% reflectivity.
