    Dust Spots

    Hello,

    Could someone tell me where the dust spots are on this photo
    http://www.jetphotos.net//viewreject_b.php?id=1655851

    I cant see them,i did my best to clean it up in photoshop,but i didnt realise i had dust on my CCD,and i've ruined about 2 months worth of decent photos,i cleaned the camera yesterday but it's too late to save the photos even with photoshop judging by this photo.

    There are no 'dust spots' as such but I think the screener is refering to the 'dirty' halo around the aircraft - it looks a compression issue more than anything else - the sort of thing you see when a file has been saved with a high compression rate.

    Hi Gary,

    Hopefully this will help:



    It does pay to keep your sensor clean, and I usually sensor swab my 30D once every 3 or so months. I'm sure some of your images can be rescued. If you'd like me to have a go at getting rid of the spots on a few of them just drop me a PM and I'd be more than happy to.

    So do I, it's just that my crap is slightly more accurate than yours!

    It's a function in Photoshop called 'Equalise', although I believe only Elements 8, CS, CS2 and CS3 have it. I may well be wrong though!

    PS 7 also has it. To use it to find those horrible dust spots do the following :

    1) open original image
    2) create duplicate layer
    3) select duplicate layer then 'equalise' (from tools menu)
    4) select original layer
    5) selecte healing brush icon (3 squares on a diagonal) and apply to dust spots.
    6) Turn off / on layers to make sure all are gone
    7) Delete the duplicate layer (not the background layer)

    voila - a dust free image.
