Abhinava Goswami Posted February 21, 2008 Share #1 Posted February 21, 2008 Advertisement (gone after registration) I had problem in my cameras light meter I think that it could be because of the white paint spot that made for the light to fell on it for photocell which reads light from it,so my cameras white spot on the shutter curtain went slight dirty/fade so what can be done to fixed it up.

Advertisement Posted February 21, 2008 Posted February 21, 2008 Hi Abhinava Goswami, Take a look here M 6 Metering. I'm sure you'll find what you were looking for!
j. white Posted February 21, 2008 Share #2 Posted February 21, 2008 The white metering spot on the shutter curtain is not meant to be a pure white - there is always some texture from the curtain that "pokes through". However yours may have faded to due exposure to the elements and/or the sun. My recommendation is to have a CLA done by a reputable repair person and mention the metering issue.

stunsworth Posted February 21, 2008 Share #3 Posted February 21, 2008 I admit that when I bought my M6 I thought there was a problem because the dot wasn't pure white. The photographs were ok, but I wondered if I had a problem camera. Looking at other people's 'dots' reassured me that mine was ok. Link to post Share on other sites More sharing options...
rubenkok Posted February 22, 2008 Share #4 Posted February 22, 2008 Hi Abhinava, I had problem in my cameras light meter Maybe you can check it with a handheld light meter ?! All the best Ruben Link to post Share on other sites More sharing options...
nobbylon Posted February 22, 2008 Share #5 Posted February 22, 2008 It's my understanding that each camera's meter is calibrated at the factory so variance in whiteness of the spot doesn't matter. my ttl's spot is very white whereas my now sold m6 classic's was very mottled, no difference in meter readings between the two.

Abhinava Nothing. Don't even think of 'fixing it up'. It's supposed to be a dirty off white with uneven paint work. The reflective value of it is the exact equivalent of 18% grey. The M6 meter can sometimes become inaccurate but this is due to the electronics of the metering circuit, not the paint job on the shutter. M6's that are 15+ years old are candidates for a replacement meter circuit. This is sometimes advised if you send it for a CLA. A cheap and easy alternative is to cross-check a subject of constant reflectivity with a separate meter to determine the extent of your M6's inaccuracy, and apply a correction factor to the ISO dial on the back of the camera. The correction factor will be constant. Link to post Share on other sites More sharing options...
denik22 Posted February 23, 2008 Share #8 Posted February 23, 2008 I admit that when I bought my M6 I thought there was a problem because the dot wasn't pure white. The photographs were ok, but I wondered if I had a problem camera. Looking at other people's 'dots' reassured me that mine was ok. I found that the M6 metering was very close to ambient readings from my Luna Pro Digital meter. Could it be possible that the reflection of light on the (12.5% gray) off white dot is calculated as a ambient reading instead of a reflective reading by the meter?
