I was asked last week about post processing software. Many of us use Adobe Lightroom and or Photoshop. If you have the latest and greatest versions of Lightroom and Photoshop then you will have to pay for the Adobe subscription service. There are many alternatives to Adobe which are not on a subscription service such as ON1, Capture One, Luminar and many others. There are also some free software for photo editing; GIMP, Paint.net, Pixlr etc. This question reminded me that I have a problem where the latest version of Lightoom is making my computer run slow. Can anyone give a recommendation, based upon experience, of alternative software I should consider?
