janlu Posted July 1, 2013 Share #1 Posted July 1, 2013 Advertisement (gone after registration) Hello , and good morning to all , here's a whole frame from my M9 . Look at the bottom.... What is this in your opinions ???? Take in mind that i haven't never done a wet cleaning on my sensor so it's impossible is some liquid agent .... At the same time with the rocket blower it doesn't change position !! It is a shot at F16 with the 28Cron........also there is a strange purple spot in the very center of the frame.... Any help greatly appreciated....Thanks in advance . Regards, Gianluca Welcome, dear visitor!

luigi bertolotti Posted July 1, 2013 Share #2 Posted July 1, 2013 I think it's too "curved" to be a scratch (and this excludes also a damage related to pixels in themselves) , also too thin to be oil, I'd say... so I'd bet for hair not necessarly from a person (have you a cat ? ) Link to post Share on other sites More sharing options...
janlu Posted July 1, 2013 Author Share #3 Posted July 1, 2013 Thanks Luigi for the reply .... and i have no cat... What do you think also about the purple spot in the center of the frame ??? Best, Gianluca Link to post Share on other sites More sharing options...
jaapv Posted July 1, 2013 Share #4 Posted July 1, 2013 Actually the whole sensor is pretty dirty. I would start by giving it a proper clean. Link to post Share on other sites More sharing options...
janlu Posted July 1, 2013 Author Share #5 Posted July 1, 2013 Yesterday night i have checked the sensor with a lamp to look if i could see the scratch , hair or whatever it is.....indeed i saw it !! Is it possible that the light of the lamp was the cause of the purple in the center ???? Thanks, Gianluca Link to post Share on other sites More sharing options...

Is it possible that the light of the lamp was the cause of the purple in the center ???? Thanks, Gianluca ... and what was it ? scratch ot hair ? Sorry, but I can see various spots of what seems to be "standard dirt/dust" but not the purple one....

250swb Posted July 2, 2013 Share #7 Posted July 2, 2013 Advertisement (gone after registration) Is it possible that the light of the lamp was the cause of the purple in the center ???? I can see the purple splodge in the centre and it could be almost anything if you are photographing a wall with artificial light. The best thing to do is stop the lens down and photograph the sky, then boost the contrast in post processing. As others have said a wet clean is needed to eliminate the obvious dust, and anything left after the clean (hopefully not) can be investigated further.

ethaninthestreets Posted July 2, 2013 Share #8 Posted July 2, 2013 Hi, I had the same problem when taking photos under F16, dots all over the sensor. I found this clip that shows you how to use rocket blower to clean up the sensor with ease. I did it and now the sensor is clean. This is all I did, I didn't dare trying out so called the "wet cleaning" method. You probably want to send it to the Leica store and let them deal with it if the "blowing" method didn't work out. I also purchased a "dust aid" sensor cleaner, which I haven't try out yet... Link to post Share on other sites More sharing options...

Sorry, but I can see various spots of what seems to be "standard dirt/dust" but not the purple one.... (but the Monitor of THIS office Notebook is in turn rather dirty... ) To my eyes not an hair for sure....... but difficult to say exactly . if you look at the very center of the frame.....that area is very purple in color.....

CalArts 99 Posted July 2, 2013 Share #13 Posted July 2, 2013 fwiw, this is a good thing to have if you clean your own sensors: Amazon.com: Carson® 5x MiniBrite LED Lighted Slide-Out Aspheric Magnifier with Protective Sleeve (PO-55): Sports & Outdoors It lets you see exactly what sort of crud is on your sensor and also how well you cleaned it afterwards. The magnification is just right for a FF sensor and the LEDs are very bright. Plus it's inexpensive. Link to post Share on other sites More sharing options...

chris_tribble Posted July 4, 2013 Share #15 Posted July 4, 2013 On US Amazon it cost 9 bucks while UK Amazon lists same item for £26 I noticed that too! Given the over pricing of the Visible Dust sensor loupe (the switch on mine is now very unreliable) this looked like a cheap and cheerful alternative - but not at the UK price!
