Well after having a rejection for Bad Dirty i thought i had better take a look at the state of my sensor. I thought everything should be ok seeing as the camera was only 10 weeks old. And the dirty must have been something on the UV filter .... WRONG !!!!!

Take a look at this test image taken against a white door at 45 over 30 seconds !!!!! Jesus theres more spots than a teenagers face !!!! And a couple of them seem to be the size of a small country.

http://img8.exs.cx/my.php?loc=img8&image=mycrapsensor5ob.jpg

I checked inside the camera and i can even see a couple of the little ba#tards with the naked eye. I tried the good old air brush but they just laughed at me.  Sad

Is this normal to have so much crap on your sensor in such a small amount of time..... Its not like im out in the desert or anything. And the camera must have only been used 20 odd times !!!

I know people are going to say "just clean it" but im VERY nervous to do this seeing the luck im having at the moment. Are there any places i can take it for a quick clean ????

A very pissed off (Sorry for that but im starting to get real annoyed)

Factory dust. Your luck is nothing to do with it - swab it and continue to enjoy your camera and keep giving us great shots.

those sopts seem to be more dirt than dust. from my own experience, dust spots seem to be fuzzy and often look like a light smudge. these spots are pinpoint sharp. please correct me if I am wrong!  dopey

Simon - did you take that with a very small f-number? When I have done a test image using f-22 stuff still shows up, even immediately after I have cleaned the sensor. A colleague from here suggested to me that maybe it was impractical to hope that everything could be removed - maybe he's right.

All I can say about the cleaning is that I'd be surprised if you could be more nervous than I was about that. I have a history of ....ing things up that I try to mess about with, and I was damned if I was going to do that with my camera. However I became sick on having to do a lot of cloning and, following reassurance here, I took the plunge and ordered Digipads and the Eclipse fluid. It came the next day (from Warehouse Express - very efficient) and, after staring at the package for 3 hours  Wink I took the plunge.

I can vouch for the fact that it is a great deal less stressful than I had feared - plus it does make a difference. You can see the fluid evaporate immediately and the individually packed pads (complete with applicator) definitely are free of any contaminant that may harm the sensor glass.

Not the cheapest thing to do, but almost guaranteed to be cheaper that taking it somewhere to be cleaned (I couldn't find anywhere here in Manchester anyway). The you can check the result. Confident in the knowledge that you can give it a go without fear of doing any kind of damage. So I would encourage you to have a go.

Good luck.

With the lens stopped right down the dust does show up more sharply as I discovered after taking some hangar shots and forgot to change my shutter speed back once outside.
I used a soft plastic pipe fitted to the pipe of my vaccuum cleaner (well my Wife's actually LOL) and cleaned the whole inside of the camera, being very careful to not actually touch the sensor. Not a good idea for too long as the vaccuum cleaner, a Dyson, protested at the much reduced airflow and was also bloody noisy.
Do they usually make some sort of noise ?
I prefer this rather than simply blowing it around the camera only to appear again later.
Don't forget to keep your rear lens cap and body cap spotlessly clean!!!!!!!

My DSLR started showing dust spots after 6 weeks of use. I ordered a bottle of eclipse fluid and sensor swabs. After more than 15 months of use I had to clean my camera two times. The swabs do a good job at removing dust and although the solution is a bit pricey, you get 12 swabs that can last you for years! IMO it was a good investment. I got mine from www.crownphoto.co.uk.

I have no idea how the hell you could absorb such amount of microorganisms inside your sensor...Man you have to think where and what have you done when changing lenses. It was a windy and dusty day? How you change lenses?
I normally put the camera down when remove and insert a lens. In one year I had to clean once my sensor. Of course got some dust but Photoshop do the job...

Hi Simon,

I had the same problem with My D70. I used ''canned'' air to get rid of the dust and it seems to be clean for the time being. I had a whole wave of rejections for baddirty and didn't realize what caused the problem.

The thread I started can be found at Rejected Photos Help (by Andy777 Mar 11 2005 in Aviation Photography)

I learnt a lot a from the thread especially about spotting marks on pictures caused by the dust before I upload them.

Sorry about the "white". Trust me it is a white door but the light bulb i think is one of those tinted ones and it give a yellow hint..
I think all of them are dust apart from the two big ones. I think these maybe something a bit bigger. The spots do appear fuzzy on f stops below 10. The example is at f/45 !! And hence the sharpness.

Hi Paul. The test image was on f/45. Most of the spots are removed at about f/15. But there are a about 10 that are still there at f/10. Theres even 2 that show at f/8 which is a real pain !!! With regards cleaning the sensor , after reading your reply i think i will also take the plunge  Smile

Believe it or not im very carefull when i change lenses. I do not shoot in any dusty conditions and that is why im so surprised it got dirty so quick.

Thanks all

Simon, I have a dustproblem myself with my new 20D, whereas I never had a problem with my D60. Must be something related to that camera.



This is my first outing with the 20D, and there are spots everywhere, but with some layer techniques and equalising the image, they are easy to remove. I am planning a cleaning though.

PS. There were some good shots this first outing  Wink:

Hi Wietse..

Care to elaborate  Smile .

I have checked all my Photoshop books and none have these techniques for removing dust spots.... So a workflow for these methods would be very helpfull.

Thanks again

Ok, I assume that you know about the "equalize" function in Photoshop? If not, it creates an image that looks like the Phantom, the dustpspots are emphasised.

So here is the workflow:

1. Layer -> Duplicate layer
2. Press F7 to bring up the layers window
3. Select the new "Background Copy" layer (just click on the name)
4. Image -> Edit -> Equalise
5. Select the "Background" layer. You will still see the equalised image, but all editing you do are done on the original layer.
6. Select heal tool
7. Heal the dustspots on the image. You will not see the spots disappear, but the do disappear on the original image. Remember which ones you did already. If you healed all dustspots, -> step 8.
8. Right click on the "Background Copy" layer -> Delete Layer
9. You should now have the original image with the spots removed

Wietse's method is identical to my own.

The 20D seem much susceptible to collecting dust spots than the D60 was...

Well im going to take the plunge.

Can someone confirm. Whats the difference between Sensor Swabs & Digi Pads+fluid. I can't see any apart from the swabs seem to cost alot more.

Also regarding the air gun/tin. Are the any rules as to how close you can go to the sensor. Apart from obviously touching it...... Is 1 cm away from the sensor to close ????

Thanks

Simon,

Can only comment on the pads - I think the only difference is the cost: I think Digipads are from the UK and the other swabs are from the US.

As I said, I bought mine from Warehouse Express, and the whole thing was ultra efficient.

Go for it - I am sure you, like me, will feel a lot happier about all this when you take the plunge.

Just to stick my oar in (though I don't know this), I would guess that you can get close to the sensor glass so long as the air blast is not enormous and you don't touch anything. Don't forget - it is glass in front of the sensor you're getting close to.

All the best.

Paul
