As an editor there is one thing that drives me crazy when it comes to refusing otherwise good images. Sensor dust - it can make a perfectly good landscape look ugly. Studio shots are not insured against it either. It has one of the simplest solutions, but if not dealt with can lead to a lot of disappointment.

It appears to me that while quite a few contributors do take the time to continually inspect their gear for dust, others may not even know that it's there. The simple fact is, if you own a DSLR and change lenses on it - you've got it. Point and shoots, on the other hand may suffer from lens dust (or even worse - hairs), which is not any better.

As a matter of fact, brand new cameras (DSLRs) may also have that issue. Or even worse - there's been reports of cameras...
