    Default DSLR Sensor Cleaning with Wet Solution?



    What are your opinions on cleaning a DSLR sensor with the many wet solutions out there? Some "pros" fell that it's not a good idea. There is a YouTube video of a photographer showing his method of dry cleaning with special brushes, loupes and static pads. A little expensive.

    Anyone use the swabs?

    Don't most Cannons have a sensor clean routine built into them?

    Yep - my Canon 60D has the sensor cleaning function - and it has stood me well for several years now. In fact I have to remember to disable it between taking my lights and my flats - just in case. I too would be afraid to go near the sensor - but then I am more fearful than Tom for most gear tweaks - take a look at his mount tuning blog sometime!

    Don't want to hijack the thread but why would you turn it off when shooting flats Bob? The only time it runs is when you turn the camera off.

    It runs when I turn the camera on as well. I used to do my flats the next day after bringing everything in, so I got into the habit of turning the cleaner off, in case something got onto the sensor while imaging. In that case I wouldn't want the cleaner to get rid of it before collecting the flats.

    Yes, it has auto sensor cleaning but I am having a real problem that I can't get answers for.
    My flats showed a real problem where there is some kind of "stain". I use the tshirt method and have shot flats at twilight and recently indoors at laptop screen. When stretched there is a "stain" showing up. Shows up on individual subs also but not as severe. Nobody seems to know what it is. I don't see anything in the sensor but am now worried it's in the scope optics.

    Hrm that looks like some sort of gradient problem. I see a lot of dust motes but they are not 'on' the sensor. The stain however like I said appears to be some sort of gradient issue.

    I assume you have tried all the usual tricks of rotating the cam etc to see if the pattern moves or not.

    Could you drop a couple of the flats into a drop box to have a close look at?

    Tom - I have uploaded 6 files to drop box. I just did another set of FLATS. These were shot at twilight with tshirt. 50 flats...then camera rotated and 50 more. I have included individual sub of each and a stretched jpg of each. I have also included a stretched jpg from the other night (Master Flats All Subs + File marked ISO 800) shot with laptop AND included that sub also. This was the worse.
    Am worried that problem is inside OTA. I have cleaned the sensor and examined with loupe. It looks clean.

    Any help would be GREATLY appreciated!
