Photos are great but pencil sketches have their appeal too. This is true for many things, from portraits to landscape to great architecture. Of course, not all people know how to draw or sketch. Or even if they do, not all would have the time to actually draw or sketch something.
But here is something I learned. There are a lot of freewares on the net which allows you to convert photos to images that looks like a pencil sketch. The programs allow you to upload the photos in order to convert them. There are even other programs that turn your photos into caricatures. Now I know how some of those blogs got those nice cartoons of their author.
If you want to play around with this tool, check out Sketch Master v4.7. It is totally free. The "pencil sketch" above is one from my pic of the main building of the University of Santo Tomas.
