I used a photo I'd taken previously but used a software package called Painter to give it a more 3D oil painting kind of an effect. This was not a one filter action that you see some people use in photoshop for example. It included essentially making every brush stroke you see ... including varying widths, colors, different brush strokes, etc and working on several layers some with masks. I used different approaches on the flower versus the background. I this case I didn't make the changes overly dramatic as I liked the original flower image and tried to remain faithful to it ... but could have
For example, a water color version would have been much less photographic.
Almost any image processing function that depends on tools designed to allow varying it's effect through pressure sensitivity (more than 20 in photoshop) and/or creating new natural medium type (oil painting, water color, chalk, pastel, etc) can be much more realistically done with the pen/stylus of a graphics tablet. While the latter is perhaps a little more obvious, even in image processing many alterations are applied selectively to just portions of the image, or in varying amounts, and these subtle changes are easier (and sometimes only possible) with a graphics tablet versus a mouse. The pen of a tablet can easily allow us to draw a line of varying widths depending on pressure which makes the picture look more real (versus an even lined drawing typical of a mouse which is a dead giveaway that it was generated on a computer). And it is an action that is so natural to most of us because we do it all the time in real life.
Sorry for being so long-winded. I'm certainly looking forward to playing around with the new possibilities. Oh crap ... even less time to metal detect now.
