MONOMAD : DIGITAL NOISE // Ruido digital [ENG-ESP]


I like the sound of that, even though some people don't like to see it in their images. Well, digital noise is produced when we take a picture in a low light environment with high ISO values. This causes the sensor cells to become more photosensitive and "exposed" in our image. We lose sharpness, but we gain in freezing a memory. Sometimes you can't have everything, right? Here is a test I did using the most extreme ISO values of my Canon EOS Rebel t3i camera. I took the same image at ISO 100 and ISO 6400 to see the difference. Notice the noise.

Me gusta como suena éso, a pesar de que a algunos no les gusta verlo en sus imagenes. Bueno, el ruido digital es producido cuando tomamos una fotografía en un entorno con poca luz con unos valores ISO elevados. Ésto hace de que las celdas del sensor se hagan más fotosensibles y quedan "expuestas" en nuestra imagen. Perdemos nitidez, pero ganamos en congelar un recuerdo. A veces no se puede tener todo, ¿no? Aquí les dejo un ensayo que hice utilizando los valores ISO más extremos de mi cámara Canon EOS Rebel t3i. Perciban el ruido.
