Photoshop or CorelDraw?

Adobe Photoshop is the most used premium photo editor on the block, fully-featured but certainly not easy to use, you'll need to spend time and efforts to learn before you can use it to produce desired pictures. Also, the basic plan on it starts from a $9/mon.
So, if you just occasionally need to use it, to make logos for your sites or what, then a free photo editor would meet pretty much all of your basic needs. Check the most used free alternatives to PS like GIMP, Pixlr, Fotor and more in Top 5 Free Alternatives to PS.
