Kos is resorting to the worst kind of smear tactics. Had he done even a few minutes of research, he would have understood the processes involved.

I am a graphic designer with a quarter-century experience in advertising and image manipulation. I expose the entire matter — citing competent authority — in this piece:

My post points out that Obama’s image is darkened even more severely in the famed “Obama Girl” video, as compared to the original footage (from his 2004 DNC speech).

Neither Hillary nor Obama Girl meant to offer a racist insult. The darkening is a result of the codecs used. The widening is a common and expected artifact of variance in pixel aspect ratios (PAR), as explained in my piece.
Race is an explosive topic; Kos should have done his research before he decided to play with fire. He has never before behaved so disgracefully.

1. Her campaign workers sending out e-mails in Iowa and S.C. accusing Obama of being a Muslim
2. Her co-chair alluding to Obama’s possible drug-dealing past
3. Her sponsoring robo-calls that used his full name (Hussein) as a blatant attempt to malign him
