This 4 x 5.65" Tiffen ND Filter 4x5.65 7-Stopis a solid neutral density filter providing a 7-stop exposure reduction. This 2.1 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 4 x 5.65" / 101.6 x 143.5mm.

Q: 8. 1. Can stop bath be reused?2. For a 500ml bottle of concentrate, whats the best way to use and preserve? mix per use? how much fits in a tank? do i get a new empty bottle and mix diluted in there and pour back in there after use?

A: Yes, IlfoStop can be reused until the indicator dye goes from yellow to purple. The concentrate will keep for 5 years in a full airtight bottle and 12 months in a half full tightly capped bottle. In working strength, it provides 7 working days. The amount that goes in the tank depends on how many rolls are being developed or the size of the print. A new empty bottle should be used to store the chemical after being mixed and once it has been used for development for reuse at a later date.

Q: 9. After mixing the concentrate with water. What is the maximum time to be able to reuse it again?

A: The working strength is good for 7 days.
