Aparatele foto nu intotdeauna pot captura zonele cu diferente de contrast mari.
Una din solutiile (ieftine) este de a face 3 poze cu valori de expunere diferita a aceluiasi sub iect.
Dau ca exemplu o poza facuta de mine in catedrala din Uppsala.




Pentru compunerea celor 3 poze am folosit programul Photomatix (http://www.hdrsoft.com/).



Alte solutii ar fi sa folosesti filtre graduale care sa reduca lumina numai in anumite zone, dar nu este intotdeauna usor sa poti aplica filtrele doar pe anumite zone ale compozitiei.

Alte resurse HDR

Si alte resurse pentru "simulare" a filtrelor ND

Din punctul meu de vedere fotografia HDR este mai frumoasa din punct de vedere asrtistic decat cea black & white.Dupa parerea mea e mai greu sa tragi color decat B & W.in HDR exista o gama larga de modalitati de a ne juca cu culoarea.
