Above- Cropped version of photo NH69727 (full sized version can be seen here). This is quite possibly a still taken from the battle film shot on 24 May 1941. The traditional description of this photo is of Bismarck, astern and to starboard of Prinz Eugen. She has just fired a salvo at Prince of Wales.
Some reversed photo theorists have claimed that this photo does not have enough detail to allow us to determine the exact orientation of Bismarck. They merely state that the silhouette is of Bismarck ahead and that this image fits their imagined sequence. They claim that they see the backs of Bismarck's forward turrets. This, of course, is clearly mistaken.
A close review of the photo reveals some very prominent details...specifically in reference to the forward turrets. One can see their side and forward angled roof plates pass in front of the forward superstructure. This would not be possible if the photo were reversed. Additionally, anyone familiar with the silhouette of Bismarck can see that the ship is approaching, not pointed away. Take a look at the photo at the top of this page, then take a look at the images below:
The above images are an enlargement of NH7927 as well as 2 comparison photos taken of a scale model of Bismarck. As you can see, there is just enough turret detail to prove that the turret sides and fronts are visible. Additionally, this is part of the same segment of the battle film as proven photo NH69726. NH7927 and the corresponding section of the battle film are NOT reversed. Bismarck was indeed to starboard of Prinz Eugen at some point during the battle. Most likely from 0603 to 0608 (during a series of torpedo avoidance manoeuvres).
