This 5.65 x 5.65" Tiffen ND Filter 5.65x5.65" 3-Stopis a solid neutral density filter providing a 3-stop exposure reduction. This 0.9 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By increasing your aperture or slowing your exposure time, you are able to control the depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 5.65 x 5.65" / 143.5 x 143.5mm.

Q: 1. I'm new at this so when it says 1+19, how much stop bath and how much water am I exactly mixing?

A: Since 1 + 19 = 20, you will divide your FINAL volume into 20 parts. Let's suppose you want to make 1 Liter (1000 mL) of final solution. In that case, 1000 mL 20 = 50 mL. So each part will be 50 mL. Since the directions call for 1+19, you will mix 1 part Ilfostop (1 x 50 = 50 mL) with 19 parts water (19 x 50 = 950 mL). Hope that helps!
