A tip:

As noted, you can take a picture of the sky or a piece of blank paper to see the spots on the sensor. However a lot of instructions leave out a step. If you just look at that image, it's hard to see the dirt. If however you run the image through something like Elements and invert the colors, the dirt leaps out in the picture. I think the command in Elements is F12, but don't remember for sure.

+1 Set a small aperture like f/22 (and don't overexpose).

Then do an "Auto Contrast." (or increase contrast greatly yourself).

If you haven't cleaned your sensor in a while, plan to get ill.

From another macro shooter,

I bought my T4i used from Adorama.

While it was just about mechanically perfect, as I discovered later, the sensor was FILTHY.  I probably never would have noticed if I didn't do focus stacking at greater than 1:1.
