| This blue glass filter is designed to fit over the eyepiece of Peak and Omega Micromega enlarging focusers. For very critical black and white printing, the BG filter is used to closely match the spectrum of light used to focus the image to the spectral sensitivity of the photographic paper. Fits Peak Model 1, 2, and 3 focusers, and the Micromega Enlarging, Grain, and Critical focusers.
Note: The BG filter is included with the Peak Model 1 and Micromega Critical focusers. |
