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 It seems like most books on the subject are already outdated (i.e. pertain to version 1.0; I have 1.2) or are not good.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?
Pinhole photography is fun. You can get pre-made pinhole body caps. They’re not too expensive and pretty good. The problem with making your own is getting it dead center in the cap. If you have any idea of getting some amount of sharpness in your photos at all, use a precision drilled pinhole.
