Frank, Mike, MikeV, Sol, and Uwe
Thank you all for your very kind compliments on my Maurolycus observation. I was impressed with the amount of detail that I was noting over the region (especially the floor of the plain). I actually noted detail that I did not record as the Moon was obstructed by my home. The northwest section of Maurolycus is very complex consisting of small craters/pits surounded by bright ridges and rifts as well. This section represented a challenge to render.
I promise to show an example of how I did it soon but I initially recorded the position of the craters/pits then slowly added the bright ridges in sections. One can produce such "mottling" using filters provided by image processing software (e.g. Paint Shop Pro, Gimp, Photoshop, etc.) as well.
I currently use a Wacom Graphire 3 graphics tablet (4 x 6 inch) for my digital renderings. Wacom, as well as other graphics tablet manufacturers, makes a variety of graphics tablets for the digital artist that fits various budgets. The more expensive Intous graphics tablet (2,048 levels of pressure) is great for the dedicated graphics artist but the less expensive Bamboo (512 levels of pressure) is more than adequate for the majority of artists. http://www.wacom.com/index2.php
I look forward to everyone's future observations.
