So, the shoot is over and you need to deal with the material you got from it. There's always the allure of sorting photos, setting the ratings and labels directly to the memory card, moving photos to different folders and then just deleting what's unnecessary from the card.
However... writing to a memory card outside the camera is unsafe (USB malfunctions, sudden disconnects, card failure, spontaneous computer reboots - any or all of these may cause a disaster).
We are often asked, how do we deal with these limitations and risks ourselves? Now, we're not saying that this is the only way, but here is what we do: we follow 2-stage workflow for sorting photos, which avoids both writing to a card and wasting time and disk space on copying and ingesting (into Adobe Lightroom) all the files while some of them may be “missed shots”.
