Magna studio? I haven't messed with that. What do you think of it, Keno?
Oh man, I have nothing but good things to say about manga studio 5, I originally picked it up to work on a graphic novel I've been working on,(if you do or want to do manga, this is it) but it is fast becoming my favorite digital sketching tool (I've only been messing with it for like 5 days).
The best way I can describe it is a hybrid of Illustrator,SketchBook and Photoshop with a dash of 3d, among the things that so far have swooned me are the ability to work in vector format (all those lines are editable splines, but you can also work in raster), it also has a very basic 3D engine, so you could model something in rhino, import it, do some basic rotations or scaling and then sketch or render with tones/markers, it also comes with 3d human mannequins that you can articulate and then sketch on top and a ton of manga specific tones that are begging to be used in ID. By far the biggest time saver are the rulers. 1,2,3 point perspective, parallel spline rulers ( for form exploration), focus lines, curved focus lines etc, and of course pretty awesome pens and markers, did I mention it is only $35 ? The only draw so far is the sometimes inscrutable interface since it obeys comic/japanese conventions (draft with pencil, ink and then render ) and a 1,000 page manual I am slowly chipping away.
I'll try posting some more ID related sketches & findings,but yeah good stuff so far.
