OBLIQUE VIEW, BAKER TEST. As is well known 

 to photographers, use of yellow, orange, or red 

 filters cuts down the amount of blue and ultraviolet 

 light reaching the film, thus cutting out haze and 

 leaving a dark background of sea and sky. Such 

 filters were put to especially good use at Bikini, and 



are in large part responsible for the excellent con- 

 trast obtained, particularly in photographs taken 

 from the air. A few polaroid filters were used also. 

 Some of the high-contrast photographs shown here 

 actually provide greater contrast than was avail- 

 able to the naked eve.
