Message definition (Showfoto/Brightness)

The <menuchoice>Gamma</menuchoice> control is like adjusting the curves tool upwards in the middle (see the figure). It affects mostly to the middle gray levels. Blacks will remain black and whites will remain white. (unlike <menuchoice>Brightness</menuchoice> control where blacks become gray). It compresses the histogram in the right part by compressing highlights, but shadows are expanded and thus causes to extend contrast there.

Il controllo Gamma corrisponde a regolare lo strumento curve verso l'alto al centro (vedi la figura). Influenza per lo più i livelli medi del grigio. I neri rimarranno neri e i bianchi rimarranno bianchi (a differenza del controllo Luminosità dove i neri diventano grigi). Comprime l'istogramma nella parte destra comprimendo le luci, ma le ombre vengono espanse e quindi comporta l'estensione del contrasto tra queste.
