“3. Pinta: Sometimes simplicity is the most important thing a
program can provide. Pinta is a simple paint and image editing
program modeled on the success of Paint.Net for Windows. Pinta is a
completely free and open source alternative that gets the job done
with as little as possible. Nevertheless, it supports layers, has
numerous effects, and allows you to save in any of the popular
image formats.“4. DigiKam: This is perhaps the mother of all photo management
applications. DigiKam, another KDE project, manages all the photos
in the folders you specify and allows you to organize them however
you see fit. It has tons of features, editing effects, renaming
tools, slideshow and gallery creation, social media and cloud photo
uploading, digital camera downloading, and many other features
amateur and professional photographers need.”
