"For now, absolute #1 RAW image processor. You have to be a bit technically inclined. Can be hard to learn (1-2 months) but then deprecates any other processors, incuding commercial ones.Vector and bitmap masks with 30 use modes, tons of powerful tools (modules) that can be used multiple times for different parts of image. DT is in fact a toolset to make your own RAW processor, suited to your workflow. But for previewing/culling/sorting your image collection DT is still painfullly slow and anti-workflow. I use ART for these purproses, then open images in DT for processing."
