I guess it's time for a clean???

[paulhillion]

My 10D is less than 3 months old & I'm extremley careful when changing lenses, however when looking through some shots taken today I noticed these 'spots' in the blue sky area? I changed lenses but the spots remained in the same place. I take it that this can be cured by cleaning the sensor?

Any advice would be most helpful.

Regards.

the best way to check is set aperture to 22, take a clear shot of blue sky, without cloud preferrably.

then apply Auto level in photoshop, if there are black spots on it, then you need to clean sensor.

of course, make sure glass is clean before you take it.

No doubt about it. Those are typical dust-on-the-sensor spots.

Ditto and make sure you have it cleaned by a pro, not worth ruining the camera because you feel a bit thrifty :D hahaha

I got your PM sGu & did what you said, thanks for that. WOW, there sure was alot of spots! I'm quite surprised as the camera is less than 3 months old! I guess I'm gonna have to get cleaning!

Thanks for your advice.

PS. Congrats on a good win yesterday!

no problem, glad to help :D

what good win yesterday? are you talking about football? otherwise i'm totally lost ... :shock:

[paulhillion]

Sorry yes I was talking about the football. I automatically assumed you to be a United fan. I'm a Saints fan myself :( .

I'm going to take my camera into a nearby Calumet store tomorrow & see if they do sensor cleaning, I'll probably end up doing it myself though.

After taking your advice on how to see how bad it might be this was the result...

Should it really be that bad after only 3 months?

Cheers.

[sGu]

it could be worse within just a day, depends on often you change lenses.

I've done far more worse than that the first day i got my 1D, was playing with 3 different lenses constantly, had to clean sensor that night!

I thought you were talking about United win, just wasn't sure :wink:

I'm surprised it made it that long.

Assuming that you don't change lenses inside an official clean room, it is going to get dust in there.

By the time my camera was three months old, I had to clean it several times. Also, sometimes our photo subjects are dark enough that we don't really see the spots. Only if you get something nice like a bright sky do you see them.

Hi Paul,

This is what "I" do and it seems to work for me. Pop on a clean piece of glass, and fire up your computer. Set the lens to manual focus and wind it out to infinity. Open notepad on your computer and make it full screen. Set the camera to f16-22 and hold the camera about 12 inches from your screen (make sure that all you can see is the light motitor screen). Take the picture, wait for a few seconds, shutter closes :). This makes it far easier to get a even light across the screen and in the UK we dont get many blue skies without clouds. Ok check out your image, pull a face, get your hand powered blower and puff out the inside of the camera, then using a clean sable brush that you dont use for anything else brush the sensor clean. Do this a couple of times and you have a nice clean sensor. Once in a blue moon I use pek pads and eclipse fluid but I've never really got on with it so use the sable for most things

All the best

Yep,it's normal for it to be about that dusty after that long.

Mine was worse when tested but didn't show as bad in the pics.You must have some big or tall blobs to show that easily.

In any case it's reasonably easy to clean it.
My favorite method is to use a pointy folded lens tissue moistened with cleaning fluid.I shine a strong light in there and pick up the specs one by one

Straight out of the box, I quickly attached my new 100-400mm to my new 10D. No stuffing around here, I was concerned about dust and other FOD (Foreign Object Damage) material about getting onto my new virgin sensor.

Would you believe it? There was a huge blob visible on my first outdoor shots. Right in the middle, where a cloudless sky should have been.

A quick clean righted the problem straight away, but I was scared !!

My local camera repair shop is an authorized Canon repair facility. I asked him what a sensor cleaning would cost,,,,$150. I about passed out and decided that I'll do it myself. To get all of my SLR digitals(4) cleaned, it would cost me $600....no way!!! Some people do this every 3 months or more. That is $2400 a year. I might as well just use a camera for a few months and then buy a new one if I have it cleaned by them.
