è da circa 6 mesi che possiedo una nikon D300s acquistata usata, macchina formidabil, tuttavia ho notato fin da subito che le fotografie pare abbiano una grana molto visibile anche a bassi iso (200 / 400).
allego un ingrandimento al 100% di una fotografia, il file NEF non posso caricarlo perche date le dimensioni (20mb) ci metterei un eternità.
preciso che scatto in RAW 12-bit SENZA COMPRESSIONE, controllo immagine SD, d-lightning OFF, NR su pose lunghe off, NR su iso elevati OFF, spazio colore ADOBE.
