innerimager Posted January 15, 2007 Share #1 Â Posted January 15, 2007 Advertisement (gone after registration) Shooting a gallery opening today in conditions that gave me the magenta streaking in my (and so many other) original M8s- that being by necessity overexposed point light sources in indoor shooting. Shot hundreds, no streaking at all. Here's a typical shot that came out fine, and another I just felt like posting. 35 lux @ 1.4, Iso 160. btw I shot many at 640 and still no problems with point lights in the frame. best...Peter Link to post Share on other sites More sharing options...

jrc Posted January 15, 2007 Share #2  Posted January 15, 2007 The woman with the dark hair looks like all the women I dated forty years ago as an undergraduate, and when I saw the photo -- please don't take this the wrong way, she looks like a really nice young woman -- I was immediately reminded of a Woody Allen short story from probably thirty years ago; it may have originally been published in the New Yorker. As it turns out, it's on the 'net. About a five-minute read:  http://woodyallenitalia.tripod.com/short-uk.html  JC Link to post Share on other sites More sharing options...

woodyspedden Posted January 15, 2007 Share #4 Â Posted January 15, 2007 By the way, an interesting thing shown here is the cyan effect of the museum glass in the pictures at the far left of the person viewing the images. I was doing a framing of an RC Gorman print last week and have always used the museum glass. When I held up a sheet of the museum glass to show my wife why I spend so much for it, there was an uncommon amount of Cyan as you changed the angle of the glass to your eyes. I have never noticed it in actual hangings (where the viewing angles are much less acute) but there is no question as to what happens when viewing angles are very extreme (as you may see on leica wide angles going beyond the 60 degree limit stated by B+W for the cut IR filters). Â Anyway, just more data as we progress in our search for the real ways to deal with these phenomena. Â Woody Spedden Fort Collins,CO Link to post Share on other sites More sharing options...

marknorton Posted January 15, 2007 Share #6 Â Posted January 15, 2007 Ths picture might not have been so rosy if one of those spots in the first image had been just outside the frame. Then you would have got a green horizontal band into the centre of the frame. This banding problem still exists and is readily recreateable and we're hopring they will fix it in firmware because, from what we understand of it, a hardware fix if one were available would likely mean a sensor replacement.

I just took a bunch of pictures with my 20D and its new 17-55mm 2.8 that had a lot of flare issues because I forgot to bring the lens shade. Par for the course, sometimes. Not that Leica shouldn't fix the problem but, honestly, the camera works fine now...there are no deal killers lurking around like in the early days.  Rex Link to post Share on other sites More sharing options...
marknorton Posted January 15, 2007 Share #8 Â Posted January 15, 2007 Rex, I don't see there's a distinction to be made between banding which occurs when a light source in the frame (fixed) and banding which occurs when it's at the edge or just outside (not fixed). They are both down to identifiable design issues. Link to post Share on other sites More sharing options...

Mark- With all the spot lights in the room, I took many shots with a light outside the frame did not get any streaking. So it's not an inevitable result of such conditions.....Peter Link to post Share on other sites More sharing options...
marknorton Posted January 15, 2007 Share #10 Â Posted January 15, 2007 The lights have to be right on the edge so that they illuminate the reference pixels around the edge of the sensor. If they are further way from the sensor, they will not cause trouble. Link to post Share on other sites More sharing options...

I have a fixed M8 aand a 486, but specifically skin tones seem problematic. Â Edmund Link to post Share on other sites More sharing options...
