Old man redux aka Free photo effects filters

The sharp photo of the old man in the blog entry below gave more some ideas..

Here is the result of cropping, sharpening, sepia, and exposure changes.

All these effects were applied without Gimp or Photoshop..

The two magic words are "Picasa" and the inbuilt tool "Piknik".
Both are free!

Wanna know the list of current camera gear I am using?
