Shootist Posted October 20, 2007 Share #21 Posted October 20, 2007 Advertisement (gone after registration) Might be worth mentioning that you can also do this with, eg, a white sheet of paper, or a white wall, or the ceiling of your room. Buying a multi-thousand-pound computer and state-of-the-art imaging program in order to be able to see the colour white isn't actually mandatory... I mean, imagine the frankly inferior results you'd get if you tried it with A WORD DOCUMENT...! I would suspect/surmise that anyone with a digital camera has a computer + monitor and some type of images editing software. But yes you can do it with any program that you can fill the screen with white. Actually I use my second monitor that doesn't have any programs opened on it. It's not white but it still works.

Hang on... now I have to buy a second monitor to do this? Jeez... the price just keeps rising! Link to post Share on other sites More sharing options...
Guest tummydoc Posted October 20, 2007 Share #23 Posted October 20, 2007 Then why did they send me an M8 full of them?? To justify the price increase My M8, purchased several months ago at the original price, had none Link to post Share on other sites More sharing options...
topoxforddoc Posted October 20, 2007 Share #24 Posted October 20, 2007 This is why the DMR is such a good product. It's the easiest sensor to clean bar none and the image quality is great. It's just not as small or bijou as the M8! Charlie Link to post Share on other sites More sharing options...
MindsEye Posted October 20, 2007 Share #25 Posted October 20, 2007 Also it really helps to turn the camera off before changing lenses because the electrrical charge at the sensor attracts dust. Don't worry about the sensor swabbing the sensor cover is extremely durable....Brad Brad, Thanks for bringing this up. I've heard this frequently for a lot of digital cameras over the years. Can anyone verify if one is really doing anything by turning off the camera to change lenses? I was reading a Q&A column a few months ago by Chuck Westfall (Pro DSLR guru from Canon) and he said there is no electical charge attracting dust when the camera is on. And of course it wouldn't really be the sensor per se that is getting dust on it but whatever filter or glass is in front of the sensor. Aren't the sensors completely sealed behind/within? So even if the sensor creates an electical charge when it's on- is it going to attract dust to the filter(s) in front of it? I'm no physicist or engineer but doesn't it have to be the right kind of charge to attract dust? And does the M8 sensor create this when on? I realize Canon's CMOS arrangement is different but I'd be really curious to get input from Leica or someone that's talked to Leica engineers about this potential phenomenon. I don't worry about it on my Canons any more but what about the M8? -Joel Link to post Share on other sites More sharing options...
Shootist Posted October 20, 2007 Share #26 Posted October 20, 2007 I'm not sure if turning it off make any difference or not. I was just out and about for 3+ hours in the hart of Atlanta and I must of made 15-20 lens changes in that time. Started with 50 Lux went to 28 Elmarit then to 35 Cron to 21CV to 75 Cron back to 50 and so on. I made all these lens changes with the camera on. I just looked at the sensor with the Visible Dust Sensor Loupe and I had 3 specs of actual threaded dust. Used the Rocket blower to remove them. A word about the VD S L. I was skeptical about it even after reading all the good things people on this forum have written about them. I was in my local photo store last Saturday, Showcase, and they had a couple sitting in one of the display cabinets. So I figured I'd give it a try. Well I really like it. It does work as advertised. You can see all the little dust particles that may get on the cover glass and you can see if you got them all. It's also good for cleaning lenses. It will bring out all those little spots that you thought you had cleaned off the lens. Link to post Share on other sites More sharing options...
arthurpreston Posted October 20, 2007 Author Share #27 Posted October 20, 2007 Advertisement (gone after registration) Lucky me!! after worrying all night long, and taking a couple of bright-sky shots this morning, I found that after the first go, some of the spots were gone. I did a new "test" of sorts: 1. Took a shot of the sky as a result of last night's cleaning 2. Cleaned the lens (21mm) thoroughly (there was some stuff on it), and took a shot of the sky after that 3. Did one more sensor cleaning, using Visible Dust liquids and the 1.33 swabs you good people recommended. I'm down to only about 3 spots, so I think the swabs and liquid - one more shot if it will do the trick. I'm very please with the results, and I will sleep better tonight. Thank you everyone! Oh, and by the way...the "purple lines" across the sensor were just a matter of having put too much liquid on the swab! I won't do THAT again either!
