.What is going on here?
Error level analysis can help you work out if a photo has been digitally altered. Photos in a jpeg file format actually lose quality each time they are resaved. We can take advantage of this to try and work out if an image has been digitally manipulated.For instance, if you have a jpeg photo at 90% quality, and resave it, again at 90% quality, you will end up with an image at 90% of 90% (so, 81% quality). If now, you were to copy and paste an element from a different photo into your current photo, you can end up with sections of the image at differing quality levels. This happens because some parts have been resaved three times, whilst some parts may have only been saved once.
If the image has had no alterations to it, all parts of the photo will be at the same quality.
How does it work?
Error level analysis allows you see to see the difference in quality level, represented by brightness. Things which are very bright have been edited most recently, whilst duller parts have been resaved multiple times. This allows you to see not just which parts of the image have been changed, but in what order the changes occurred.entonces, no solo no corresponde la fecha sino que esa foto quiza ni sea una bomba de racimo!, quiza sea un tubo con las letras amarillas pegadas con photoshop!!!.
Una manera de confirmar esto sería medir el angostamiento de las letras segun su posición en el tubo. Deben seguir la ley matemática de una proyección sobre una superficie cilíndrica.
¡Son de 4ta!, se quieren quedar con Libia y ni siquiera trabajan en esto

ResponderBorrarfotos en jpeg? todo el mundo sabe que los periodistas graficos trabajan con formato raw, precisamente para no perder pixeles cada vez que se guarda el archivo.

ResponderBorrarLa nota original en HRW solo muestra fotos en JPG.
HRW gentilmente provee un archivo ZIP de 17 MB con varias fotos... pero son todas JPEG.
Sobre el periodista que sacó las fotos
Mira el final del curriculum del "periodista" del New York Times que encontró las bombas de racimo:
"...Mr. Chivers graduated with a B.A. cum laude in English from Cornell University in January 1988. He was the 1995 valedictorian of Columbia University Graduate School of Journalism. He also graduated from several military schools, including the United States Army's Ranger Course."
A proposito: Cornell University es la mayor productora de espias y diplomaticos de Usamerica. Ahi estudió "Cordwainer Smith" el autor del Juego de la Rata y el Ratón y espia o agente de la CIA toda su vida (se supo cuando murió)
