Aging a portrait with GIMP
Este artículo también está disponible en Español: Como envejecer un retrato.
There are countless articles available on Internet, explaining how to retouch a portrait and make somebody look younger; basically, what they do is soften the skin and remove wrinkles and other skin defects. In this article I will explain the method I employ to produce exactly the opposite result: aging a portrait. This process enhances the contrast of a photo and highlights the textures; but when applied to a portrait, the effect is that of aging the 'victim'.

Painting with light

I had read on Internet about a photographic technique called 'painting with light', which can produce some amazing results. As I waited for the right opportunity to test it myself, a flower bouquet appeared at home, and presented itself as the perfect victim. A flashlight, a piece of paper, and some time later here is the result of my humble lighting experiment.

Circuit to trigger a camera using a mobile phone, PDA, or MP3 player
Este artículo también está disponible en Español: Circuito para controlar la cámara desde un movil, PDA, o MP3.
On night photography, long exposures are the norm: sometimes several seconds, and sometimes several minutes; I also tend to employ HDR techniques, and that means that I often end making series of nine or even more photos all together. Spending half an hour (sometimes more) with the remote trigger on your hand can be quite boring, so I toyed with the idea of making this process authomatic... and I found a way to control the camera from a mobile phone, a PDA, or even an MP3 player.
