I've been asked a few times over on my Twitter recently what art or drawing program I use for my comics. I've tried loads of options in the past, GIMP, Paintshop, Photoshop and even experimented with Vector art using Inkscape.
In the end I settled on Clip Studio Paint Pro, here's why!
Clip Studio Paint Pro
Clip Studio Pro is my tool of choice for digital painting in general and especially for webcomic creation. Formerly known as Manga Studio, the program was designed with comic artists in mind and has a feature set to match, which we'll get to below.
It's incredibly good value for money, with no expensive subscriptions like Photoshop. I got my copy digitally for £35 from Amazon. If you shop around you can find really good prices.
Features of Clip Studio Paint Pro for Webcomics
I'm not going to go into loads of depth, you'll find videos and reviews on the software all over. The main reason to use Clip Studio in my mind, is that as an application designed for the comic creative process Clip Studio features built in tools to format your strip, make speech bubbles and create and re-size panels. You can use premade templates or start completely from scratch.
The program supports vector and raster artwork too, so you can draw and paint naturally but keep your panels, text and speech bubbles in vector for easy scalability when you need it. You'll also find a wide array of brushes from oil to watercolour as well as a selection of inking pens, pencil presets and tonnes more.
All of these items are configurable too, so if you don't like a particular tool style you can change it or even create your own. The program is fast, significantly faster than GIMP for example on my Mac when copying and pasting or moving around large images with millions of pixels.
Give it a go!
So that's what I use, I know if you pop to the website
you can get a free trial and see if it's for you.
If you're looking for something for free to get started though, you really can't go wrong with GIMP. At the end of the day, if your ideas are good then your comics will shine anyway!
