Hugo Jaeger was one of Hitler's personal photographers who has been granted special access to Third Reich. He was also one of the few photographers from that time period who used color photograph, which is why most people assume that these photos have been "colorized" from black and white originals, when in reality these ARE the originals. In 1965, he sold his entire 2000+ photo collection to LIFE Magazine.
At one point all of the photographs he has taken could be found on LIFE.com, but since then their website has been restructed in such way that you could only view a few of them at a time.
Most of Hugo Jaeger's stuff can still be viewed on Google's LIFE photo archive here:
