Company Serif has announced the availability of Windows version of Affinity Photo, after its availabilty for Mac. Affinity Photo is a product "similar" to Photoshop, with advanced features for handling images including RAW of course.
Differently from current Lightroom product, it provides supports for layers but it misses the advanced cataloguing feature of the Adobe product. Performance are not (yet) satisfyng on Windows systems in my opinion, but price is very interesting around 50 $ one-time (discount untile 22nd of December), not like Adobe that forces user to a subscription.
The announcement from Serif is available at this link.
