I usually blow the dust off the CCD in my D70 every night following a photo session, however, I feel that I may need to do a more intensive cleaning session soon. I am somewhat apprehensive about cleaning my own sensor becauseof the risks associated with this procedure, but I would like to hear some horror stories to help me avoid making the mistakes of some of my peers. Ultimately, I would like to take on this task, but Iwant to know what is really at stake.

This is NOT that big a deal. You MUST follow some basic procedures. If you do so, the worst that can happen is that the sensor remains dirty. I post a link below. I have not examined that link thoughrouly, but I've noticed that everyone, sooner or later develops their own procedure.

You can Google Thom Hogans web site, he posts his own cleaning technique, and while mine differs a bit, it's based on his.

First, of course don't even bother if there are just a coupla of dust spots...

You clean every night?
I do a blue-sky check about once a week, and only clean if anything annoying shows up.

I've never cleaned the sensor and don't expect I will ever have to.

Heh, one question Terry, do you ever take your lens off?
Have you checked the sensor for dirt with something like the blue sky test?

Ok 2 questions:blah:.

Admittedly I have only had to clean my 20D twice since I got it about a year ago.
(and the first time was a stupid move on my part, where I changed lenses in a working wood shop).
Once the splotches become noticable and you need to retouch them out of every image it's time to clean.:idea:

Peter,

Thats a very personal question asking me if I take my lens off !

Yes, I change it over but not that often. I'm so in love with my Tamron 28-75 XR Di that it hardly leaves my 20D.

Haven't done the blue sky test. Maybe next time I take the lens off I will peer in at the sensor.

My photos look good!

Terry

also keep in mind that even if you don't take your lenses off at all.. some cameras inevitably are shipped with a little sensor dust.. or particles that are loose in the body make their way to the sensor..

I have just got back from malta and what a dry place it is! I got some dirt on my d70 sensor and cant blow it off! I am gonna have to buy one of these cleaners, which do you think is the best tool?

Also which is the best method for checking if there is still dirt on the sensor?

I think the blue sky test works quite well. Mount your lens, set a small F-stop and shoot a couple of images of the clear blue sky. Then run to your image editor and view the sky images at 100%.

Dust shows up as splotches and dots, and will be in the same place on every image.

For cleaning a lot of people like the sensor swabs and pec pads, I like the visible-dust sensor brushes.
