K20D sensor problem
Looks like I am done then. I better go and practice cloning in photoshop. Have it repaired. It'll be cheaper than a new camera, and guaranteed for a further 6 months too. Might be a silly question, but have you tried cleaning it?

K20D sensor problem
Looks like I am done then. I better go and practice cloning in photoshop. Since the defect is always in the same place you may be able to set up a batch routine to do it, certainly for the blob and maybe for the line as well. With the image at 100% use the rectangular marquee tool to surround the...

K20D sensor problem
I just tried it on your 800-pixel version. Making a marquee from top to bottom to cover both the line and the blob, then using a 3 pixel radius in the options made it all go away completely with no noticeable effect on the roof near the foot of the picture. It will be slightly different on the ful...

K20D sensor problem
Full version for anyone willing to try :) It is under exposed version where the line is visible better. Thanks Pawel

K20D sensor problem
I've produced an action that gets rid of the blob and the line, at least with the line vertical on the right like your example. Just puzzling out how to save the action so you can try it. Still large: One way to do this would be to always rotate the image to the same orientation, run the act...

K20D sensor problem
ok, for an image the same way round as the example then this action should work, copy this file to your PC first: http://www.infrared.webspace.virginmedia.com/Other%20Pictures/slides/BlemishRemoval.atn Then you'll need to load it into Photoshop using the instructions on this page: http://www...

How to clean faulty shutter wheel
Hi all, I've searched via Google, Flickr, and PUF and would still like a little help. Specifically, on my ist DS, the shutter wheel (command dial) does some strage things when turned - shutter speed goes up, or down, jumps 2 stops, same when changing aperture. I've heard cleaning with IPA or con...

Mucky sensor, dust on it I'm afraid.

marks on images, try different lens and still same place marks
As Steve says, it's just muck on the sensor. Occupational hazard. Search the forum for dust removal techniques. It boils down to three options: - A blower (hit and miss), - A device called an Arctic Butterfly (Google it, or search the forum for it), which is great for dry dust that h...

marks on images, try different lens and still same place marks
will i be able to actually see these blobs on the sensor? with the naked eye? Quite likely not. Swab; picture of blank white wall at F22; crank up the contrast. Repeat till you're satisfied, or bored. Just make sure the battery's nice and full. It's not likely, but it could ruin your whole...

This video from the people that make Eclipse fluid should de-mystify the procedure: http://www.youtube.com/watch?v=67vLGotCFd0 Good little video clip, but he broke the cardinal rule of cleaning most items. You do not wipe the cleaning medium back across the item being cleaned. Take care.

You do not wipe the cleaning medium back across the item being cleaned. Indeed, but actually he didn't. For the return wipe, he bent the swab the other way, and used the other side.

suggestion to buy some old lens...thx
Yep, for use on a DSLR A is preferable to M. The only less-desirable thing on the A lens is the plastic aperture ring, but on a DSLR you set this to A and leave it alone thereafter so it won't bother you at all. The focusing on both should be ultra-smooth, so have no worries there. To gi...

Messed-up clearing viewfinder
Confession time, I have screwed-up. I decided to give it a go in trying to clean the dust spots visible in my viewfinder (K5), as illustrated here Now I wish I had not, in that the viewfinder now resembles a barbershop’s floor: :oops: Why did my curiosity get the better of me...:evil: To ...

Messed-up clearing viewfinder
Yeah I agree with all of the above , I made a little tool out of a paper clip and it was a piece of cake to remove and change the focus screen. But the screen is very delicate ,I carefuly tried to clean the one I removed with a sensor cleaning pad and fluid and killed it .... jeff
