The program has always been an incredibly fast way to ingest, view, rate and tag images. It isn't catalogue based, which makes it much speedier than programs like Lightroom or Capture One. It is a crucial tool for photojournalists, event photographers, and sports shooters—basically anyone who is dealing with large amounts of files on tight deadlines. It's always the first program I open once I've wrapped a shoot. It helps me quickly determine what images from a shoot are the keepers that I'll be importing into Lightroom to edit.
