Re: Качество sRAW

Сообщение Петухов Сергей » 13 окт 2009 8:45

Добрый день.
При любом формате изображения всегда задействуется полное количество элементов матрицы. Что касается обработки, используемой при формировании sRAW- подробностей Canon не публикует, что вызывает массу дискуссий, например, на . Судя по исследованиям участников указанного форума, при образовании пикселя sRAW производится группировка (binning) нескольких элементов матрицы, с усреднением и интерполяцией сигналов отдельных элементов для формирования RGB- данных конкретного пикселя. Поэтому sRAW- это не просто RAW пониженного разрешения; sRAW- изображение имеет свой специфический характер, который некоторые фотографы предпочитают "чистому" RAW, и уж что для него совсем не характерно, так это "замыливание".
