Mangocast #PictureChallenge

by · Published · Updated

Para probar las capacidades “sin precedentes” de la cámara del flamante iPhone Xs Max, lo sometimos a un #PictureChallenge que consistió en tomar la misma foto con 5 teléfonos y calificarlas a ciegas, es decir sin conocer cuál foto había sido tomada de qué teléfono. Los teléfonos que compitieron fueron:

La única foto que se tomó con  las diferentes cámaras fue esta:

Vos también podés participar de este desafío entrando con tu cuenta de Google a este formulario. Ponele notas a las fotos, de manera que cada foto tenga una nota distinta: la mejor foto debe llevar 5 y la peor 1. 

Las fotos publicadas no tienen otro retoque que ajuste de rotación y tamaño para que todas luzcan lo más similares posible para minimizar el efecto de que otros detalles afecten tu criterio. Por si acaso, incluimos links a las fotos originales a las cuales lo único que se les hizo fue remover los metadatos para que no puedas inferir la cámara a partir de estos.

A propósito de metadatos, extrajimos los EXIF para que compares lo que decidió cada cámara al tomar las fotos (ofuscamos la información del GPS por razones obvias).
