Affinity Photo is now available on Windows after launching on Nov. 10. Windows users can buy the best Mac app of 2015 for free as a beta version.

Affinity Photo is the alternative for Photoshop featuring many of the same functions and workflows. Its beta version on Windows shares exactly the same back-end as the Mac version. It means that files are 100 percent compatible between both platforms.

It has a super fast feature when it comes to retouching images. It also features a RAW editing and file compatibility including PSD files used in Photoshop. It allows users to work in any colour space including the RGB, CMYK, Grayscale, LAB, End-to-end CMYK workflow with ICC colour management and 16-bit per channel editing.

It also features customisable effects with a huge range of high-end filters. The filters can be applied as live layers enabling the user to edit, mask or erase away the effects.

The beta version includes HDR merge, focus stacking, macros, tone mapping, batch processing and 360 degree image editing.

The Windows system hardware requirements include Windows-based PC with mouse or equivalent input device and DirectX 10-compatible Graphics Cards and above. A 2GB RAM is compatible but a 4GB RAM is recommended. The hard disk must have 780MB of available space but it requires more during installation. Windows 10, Windows 8.x, and Windows 7 (Service Pack 1; Aero enabled) are the operating systems compatible with Affinity Photo.

The company has not yet released the price for the Windows version. The Mac version cost US$49.99 (AU$65.86).

Affinity Photo does not require subscription to receive updates or to keep using the software.
