The Heliopan 48mm KB-18 Color Conversion Glass Filter is blue. It is used to balance daylight film under artificial, tungsten or standard (household) incandescent lighting.

We have all taken indoor photos (with traditional film) that turn out yellowish. A portrait under this kind of scenario usually leads to less than desirable results. In order to bring back a reasonable color balance to the image, a KB-18  is required.

In some instances, that "yellowish" tint may be desired to provide a somewhat "old style" look to the photo, but in general, it tends to be distracting and unflattering to most subjects.  

Heliopan Lichtfilter-Technik of Munich, Germany, has changed their black anodized brass filter rings on most Heliopan non-rotating filters to their "slim" mounts. These slim mounts are made of black anodized brass stock and have so little rim in front of the lens (5.4mm) that they will not vignette with lenses as short as 21mm.

Heliopan offers a wide selection of sizes, screw-in, series, bayonet, square and rectangular filters including digital, video, center weighted, graduated, wide angle, Kaesmann polarizers, drop-in polarizers, etc.

Heliopan cuts, grinds, polishes and coats their filters with the same techniques and equipment as used for the finest German camera lenses.
Filters still retain front threads for a lens cap, a lens hood or even stacking a second filter.
The portion of the Heliopan slim filters that are in front of the lens have been reduced in thickness by 37% over the former mount.
