A message from Apple:
I am not looking forward to this. Aperture has been central to my photographic workflow for years now, and one way or another I’m going to have to learn a new way of working with images. I’m waiting to see how good Photos proves to be – and how fast it improves – before I stop using Aperture.
If the answers are “not good enough” and “not fast enough”, I may have to buckle down and learn Lightroom. We’ll see.
The Photos beta is promising – but at a pretty early stage still.
