After I made my first class on making abstract watercolors, https://www.skillshare.com/classes/Abstract-Watercolors-create-a-series-for-a-gallery-wall/2027140917 I had some requests to do a class on how to digitally process watercolors to make prints. So here it is!
Below are links to a scanner I recommend, and where to get photoshop. I used a fairly cheap Canon "all-in-one" scanner and printer for a while (until the scanner stopped working - thanks, Canon), something like that will do the trick. However I wouldn't recommend making prints to sell with one of those. I made another class where I discuss having prints made and where to sell them online : https://www.skillshare.com/classes/Earn-Money-from-your-Art-while-You-Sleep/1668682790

I have the basic Adobe photoshop plan that is $9.99 a month. They have more expensive versions but that's really all you need. https://www.adobe.com/creativecloud/plans.html?single_app=photoshop&promoid=65FN7XFX&mv=other
