Old school artists may probably scoff at the idea of drawing on a tablet, but the more digital ones may actually welcome it (or the challenge of it). But they may not be too happy at the limitations the tablets and styluses in the market bring. But time-lapse videos from artists using NVidia's SHIELD tablet and the DirectStylus 2 and its technology show that they can do so much more than just sketch outlines or do basic drawings on the mobile device.
If digital art is your thing, then you should take a look at how artists all over the world are leveraging on the DirectStylus 2 technology that helps you enhance your artwork, start from scratch, or just do your thing over and over without wasting any paper or material. It has GPU-accelerated painting effects that can let you use the whole graphite scale, at least digitally. You can instantly change tools depending on your mood, from watercolor to sketching to oils or to whatever else suits your fancy, all without having to waste any actual materials, tediously clean up your tools.
The DirectStylus 2 doesn't look or feel like the other styluses in the market as it is angled so that it will be like you're actually holding a paintbrush. The Dabbler app, available for the SHIELD tablet is also pretty awesome, no matter what medium you use. You have full control over each brushstroke that you make. And even if you make mistakes, it can be easily erasable and you can do it over each time.
But words are no match to actually seeing how artists do it. The time-lapse videos that artists have been posting seem pretty awesome, and if you'd like to dabble in digital art, be inspired by them, and then make your own time-lapse sessions using the Dabbler app, which you can download from the Google Play Store.
