The Tiffen 4x5.65" Low Contrast Filterworks to lessen contrast across the image by creating a small amount of controlled flare near highlight areas. This enables greater detail to be attained in shadow regions, while unaffecting the values of highlights, in order to produce lower apparent contrast. This filter is ideal for use during midday and other high contrast lighting situations when it is difficult to control both overexposed highlights and underexposed shadows. The 4 density provides less contrast adjustment than the 5 density, but more than the 3 density filter.

Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 10,000th of an inch. This filter measures 4 x 5.65" / 101.6 x 143.5mm.

Low Contrast for Greater Shadow Detail    Does Not Affect Highlight Values    Ideal for Midday and Bright Conditions    ColorCore Technology

Ideal for use during midday and other high contrast lighting situations when it is difficult to control both overexposed highlights and underexposed shadows.

Lower contrast results in greater shadow detail when properly exposed.

Q: 1. What accessories would we need to enlarge 6x6 film to 50x50" paper hanging on the wall?... lenses, filters, film holders, etc. But also to 20x16" on the table.

A: The Beseler 67XL-VC-W would already have built in variable contrast filters to use with variable contrast papers. A suitable negative carrier would be the Beseler 6x6cm Glasssless Negative Carrier, BH # BENC6667. As for the lens, you would also need a lens board and a retaining ring. A lens such as the Rodenstock 75mm f/4.5 Rogonar-S Enlarging Lens, BH # RO7545RS combined with the Beseler Lensboard for Printmaker 35/67 Enlargers, BH # BELB39PM67 and the Beseler 39mm Threaded Lock Ring, BH # BEJN would be great to use. You would need to mount the enlarger to wall if printing to 50 x 50" paper. https://bhpho.to/3OKHWXo https://bhpho.to/3a1WlQk https://bhpho.to/3QWaQpt https://bhpho.to/3y0SvyN
