In the process of cleaning my camera's sensor, I've discovered a worrying problem. It seems that there is a small air bubble in the low-pass filter which cuts out infrared light and protects the sensor. This bubble casts a shadow on the sensor, especially at smaller apertures and with wide angle lenses. As such, I'm going to have to send it in for warranty repair. I don't know how long it will take to be repaired but I doubt it will be less than a month.

The ratio of pictures taken to pictures posted is quite large, so I have a significant stock of digital images I can keep posting in the interim. I'll also be shooting more film. However, there may be gaps if I run out of material I'm happy with.

...Is it bad that I only understood about 2/3 of the problem description?

Probably not, unless you're a highly technical photographer. The general symptom is that, under some circumstances, I get a little black spot on my pictures in the lower right hand part of the frame:



This spot is caused by a flaw in the manufacturing process of the imaging sensor. It's not always visible for the same reason our shadows are not always visible; on an overcast day, the light wraps around us and we don't really have a shadow, while on a sunny day, the light casts a sharp shadow on the ground. Some lens combinations cause the shadow to be distinct, while others leave it soft. Any time the shadow is distinct, that dark spot will appear and I'll need to edit it out in post-production (i.e. Photoshop).

Well, crap. About the camera, that is.

Indeed. It's not the end of the world, I do have another (old, compact) digital camera and three film cameras, but the 30D is my main tool these days. Hopefully the warranty repair won't take too long, I'm planning on emailing the Canon rep for my area to see if he can expedite the process at all.

Which, of course, leads to the inevitable conclusion that as a professional photographer I should have a backup. For now, my backup is a film camera. It's unlikely that I'll be able to afford a second digital body any time soon, but we'll see how long the 30D is out of commission.
