Most digital images intended for viewing are generally assumed to be in sRGB colour space, which is gamma-encoded. This means that a linear increase of value in colour space does not correspond to a linear increase in actual physical light intensity, instead following more of a curve. If we want to mathematically operate on colour values in a physically accurate way, we must first convert them to linear space by applying gamma decompression. After processing, gamma compression should be reapplied before display. The following C code demonstrates how to do so following the sRGB standard:

English football has no true equivalent, with Liverpool and Manchester United fans unable to agree on a name for their grand-slam meetings. Up in the land of fitba, there’s this weekend’s 450th Old Firm/Glasgow derby (delete as applicable according to your stringency on Scottish company law). And Germany has Der Klassiker, between Bayern Munich and Borussia Dortmund. The Bundesliga marketing suits have been out in force this week for the one game, played on Saturday evening, that brings extra eyeballs. Though questions are often raised over whether this is a true, classic rivalry; Dortmund have not won a league title since Jürgen Klopp was making his rounds in 2012.
