In addition to soliciting suggestions on techniques and products for cleaning DSLR CCD/CMOS sensors, I also have a couple of other things I’d like help with.
1) I bought Adobe Lightroom with money I got for my birthday. I’m trying to learn how to use it. Has anyone used it and/or can anyone recommend useful books or web resources about how to use it effectively. It seems like most books on the subject are already outdated (i.e. pertain to version 1.0; I have 1.2) or are not good.
2) Pinhole photography. I’m interested in trying this out. I asked for a couple of extra body caps for Christmas so I might try my hand at making a pinhole “lens” or two. Are there practical considerations regarding the construction of a pinhole “lens”? Is it worth buying a set of different diameter pinholes, like this? What about practical considerations when taking a picture using a pinhole camera?
