Things being what they are, I have so far totally failed to live up to my side of the bargain and have failed- utterly- to even give the program a decent test run that's worthy of some of the fantastic features that I know it has. I will get there, Manga Studio, I will!
In the meantime, here are a couple of pieces I did using the symmetry ruler, which I think is a cracking tool. Now, you might ask, "what's the point? Surely you can just create a mirror image in Photoshop that's just as good?"
Well... yes and no. Technically, you could do that- but I think that this is much better. For a start, the brushes are lovely to work with- much smoother than in Photoshop (which I live by and use every day). Also- and this might not seem like a big deal- you can draw on either side of the ruler and you'll get the mirror image on the opposite side.
Again, you might be thinking, "so what?"- but you'll be surprised by what you'll think to draw on the right hand side that you didn't think to draw on the left.
Try it. If nothing else, it's quite therapeutic.
Again- I'm really sorry that there's no actual "how to" with these images- but I was just playing around with it at the time and I didn't think to get any screen grabs as I went along. When I've got a bit more time, I'll create some proper step-by-step tutorials.
