Ogni file jpg di immagini di apparecchi fotografici ha dentro di sè tutti i dati di scatto ecc. Si leggono con appositi programmi (generalmente free, io uso exif-reader) oppure con i soliti programmi di visione foto ACDSEE, paintshop, ecc ecc.
Eccoli, dunque, presi dal file della
tua foto. (Li ho messi tutti: non chiedermi cosa sono alcune voci perchè non lo so. C'e un dato per ogni riga, spero non diventi troppo lungo il post!)
Sostanzialmente si legge che l'hai scattata ad 1/60sec, F2.8, 50 ISO, grandangolare 35mm ecc.
Per quanto riguarda il difetto a me sembra semplicemente fuori fuoco, sentiamo cosa dicono gli altri!
