The transition from film to digital eliminated problems that plagued many photographers. Things like reciprocity failure were now a thing of the past. But, it presented a few new challenges, too. The biggest of those is dust. Things have gotten better over the years. We’ve made the shift from CCD to CMOS sensors, which seem to attract less dust. We’ve got automatic dust cleaning features in most DSLRs now, too.
These days, I’ve found the majority of dust can be gotten rid of with a good blast or two from a rocket blower. It’s rare I have to take a swab to a sensor any more. Sometimes, though, you get those stubborn bits that just don’t seem to shift, and you don’t have time to send it off or clean it properly. They’re fairly easy to fix in post, though. This video from Sleeklens shows you how to quickly and easily remove sensor dust in Lightroom.
