Здравствуйте.
Сделал две фотки с одинаковыми установками выдержки, числа диафрагмы, настройками белого, без вспышки(насколько понял по EXIF, но не уверен), практически в одной позиции, с разнесением по времени в 5 сек, но они заметно отличаются по яркости.
Заметил отличие в ISO speed ratings: у первого более темного оно = 900, у второго светлого 800. Это основная причина?
