GIMP is a free program for such photo retouching, image composition and image authoring. Essentially it's the closest thing to Photoshop you can get for free.
GIMP vs Adobe Photoshop opinions
It is probably the closest alternative to Adobe Photoshop, at least from those I know. For me personally too complicated but if you know how to use it, you can do many things you can do with Photoshop too. What I also noticed is that it loads very quickly on Linux.
Free, rich of feature, good performance, many tutorial, anything it's lack can be cover with plug-in. The best for free software.
Bad user interface, difficult to learn, unintuitive, slow. Thank God for Photopea.
gimp 3.0 will be more better hope so
Irritating, totally unintuitive, completely unthought-out interface. It may have a lot of possibilities, but a lifetime is not enough to discover them and understand the twisted logic of this program.
Not similar, missing lots of important functionality. STOP PROMOTING IT AS A PHOTOSHOP ALTERNATIVE!
Versatile editing and drawing application, FOSS, great for an average user.
Krita is a professional Free and open source (FOSS) painting program. It is made by artists that want to see affordable art tools for everyone within concept art, texture and matte painters, illustrations and comics.
Krita vs Adobe Photoshop opinions
I like Krita as an alternative to Photoshop because it's open source and free from the tyranny of Adobe Subscriptions
It's kinda more intuitive to use than GIMP (which is a briliant PS alternative too) interface-wise, and supports CMYK out of the box if one needs it. As of version 3.1 it has pretty advanced support for animation, including opacity curves (GIMP fails completely in that field, animathing anything is a major PITA in it)
Krita is for painting, not photo editing
It works with legacy graphics card, it's intuitive, it has super transform tools
It's free, yet has almost all the features Photoshop has
best open source raster program out there in terms of digital paintings goes, and in some areas even better than Photoshop.
For artists using photoshop it is the best alternative.
MyPaint is a fast painting program with an emphasis on full-screen use. It lets you focus on the art instead of the program. You work on your canvas with minimum distractions, bringing up the interface only when you need it.
MyPaint vs Adobe Photoshop opinions
If you're looking for a painting app, MyPaint may be a good alternative to Photoshop. It has infinite canvas, good, natural brushes and overall good tools.
MyPaint is only a drawing program, but it can't edit images. Adobe Photoshop can do both.
My paint is not a image editor
MyPaint is a program for digital art. Though GIMP can be used for that purpose, GIMP is also an image editing software.
mypaint is really only for drawing, it's not an image editor
