Hi I have previously used Affinity photo on an ipad a long long time ago so thought i would try a trial now working on a Macbook is it possible to use a selective sharpening tool like in the ipad tutorial where you pick an object . In my case a bird and only sharpen that , I work with raw hope I have explained properly I found this easy to understand before ,must say i am impressed up to now . Any help appreciated .
