Collection of free painting and digital art programs

If you like to paint digitally, it doesn't matter what program you are using. As long as it is functional enough for you, and you enjoy painting when you use it. I love to try all painting programs, it's like exploring.

Though we already know that Photoshop, Painter and Sai are great, but there are free ones that are good enough to create artwork as beautiful as those programs. : )

Many times that I randomly posted about them but this time I want to collect them all here! So it will be convenient for you all to check and compare them. What I can say is that I'm grateful and appreciate those creators who spent their time and hard working and share them to us. 

That's why I want to support and share them and I hope they are helpful somehow for you. I will keep updating when there is any new information

Art gives us a chance to express our feeling. When we paint and enjoy it. Sometime we just forget how we feel and concern too much on something else. So it would be nice right? if we can feel that fun again. : )
