Advertisement Posted October 18, 2009 Posted October 18, 2009 Hi WmAl, Take a look here Green Stripe Again!. I'm sure you'll find what you were looking for!
Shootist Posted October 18, 2009 Share #2 Posted October 18, 2009 It has nothing to do with any lens. It is a flaw in at the edge of the sensor when you have a bright point light at the short side of the sensor. It is caused by that light getting under the black border that rims the sensor. I think it has something to do with the offset microlenses and that the black border is not actually on the microlenses allowing light to get between the border & microlneses and shine into the sensor that is supposed to be dark/black. Just move the point light either completely into the frame or well out of it. I can reproduce this with any lens at any time. Althought it is harder to do with telephoto lenses.

kalina Posted October 18, 2009 Share #3 Posted October 18, 2009 I've seen these stripes in images captured with other cameras, everything from point and shoots to my Nikon D300, so this is not a unique-to-Leica problem. It doesn't happen very often on my D300. Perhaps three times in over 40,000 pictures, but it still happens. Quote Link to post Share on other sites More sharing options...
okram Posted October 18, 2009 Share #4 Posted October 18, 2009 Really? I thought it was an M8 exclusive. Can you post some examples? Quote Link to post Share on other sites More sharing options...
scott kirkpatrick Posted October 18, 2009 Share #5 Posted October 18, 2009 I've seen these stripes in images captured with other cameras, everything from point and shoots to my Nikon D300, so this is not a unique-to-Leica problem. It doesn't happen very often on my D300. Perhaps three times in over 40,000 pictures, but it still happens. Ah, so green happens to others as well! The green stripe on the Kodak KAF10500 (in the M8) starts precisely in the middle of the frame because the CCD circuitry extracts data out to the two sides in parallel, and only one channel is affected. See this thread for an example. Does the Nikon's CMOS chip show its geometry in some similar way when it is having a green day? scott Quote Link to post Share on other sites More sharing options...
kalina Posted October 18, 2009 Share #6 Posted October 18, 2009 Really? I thought it was an M8 exclusive. Can you post some examples? It is a non-issue when I shoot with my D300. I rapid-fire shots with my D300 so I usually get doubles of almost every image I capture. Once I transfer the images to my Mac, I preview them and delete the bad ones right away. I work a lot more slowly with my M8. I can understand why people would be peeved if they missed that "perfect shot" because of a green stripe, however. My thinking is if you stay within the right lighting conditions (that is, don't shoot in places where there is blinding light), then you're fine. Check out my Thurs, Oct 8 blog entry at: Kalina's Photography Blog and you'll see examples of how I've used my M8 in my photography class (warning: you have to be over 18). So long as you don't blast light at the sensor and stay at ISO 640 or under, you'll be fine. Quote Link to post Share on other sites More sharing options...
