I've just got a wacom graphic tablet! Wow, what fun. At last something that means I can paint and draw without mess on the photo's I do.
I've been a painter since I was a little girl, recently converting to acrylic and having a lot of fun with textures and embedding things and layering and so on. There is something magical about not quite knowing how the work will eventually turn out, starting from somewhere and not worrying about where it will go, ending up with something that has the essence of the original, but not necessarily the detail.
Well, Photoshop (no advertising!!) is that for me with photography. And the wacom is one of the tools that helps. Like using a pen or paintbrush, but less messy (and there is always 'undo'), the pen means I can delicately touch up areas that need a wee bit of definition, erase areas that don't work, tidy up bits that need it, and work much more intuitively than with either a touch pad (which is what I had been using) or a mouse (which I had dumped a couple of years ago).
Oh, and why wacom? Well, I shopped around, tried a few out - and for me, the wacom's size and flexibility and lack of additional and unnecessary bundled software worked for me the best. Perhaps not everyone would want these attributes, but they worked for me.
