The best home filter coffee machineis compatible with filter holders that can accommodate filters that are 4" wide and 4mm thick. It is an ND filter with a 2x filter factor that provides a 1-stop exposure reduction. This filter's 0.3 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters are intended to not affect the coloration of the image and are ideal for pairing with other filters.

The design of this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible and infrared light. Due to imaging sensors' greater susceptibility to infrared light, compared to traditional film, color casts can occur when photographing darker subjects that require increased exposure times. To provide a high level of neutrality across the visible and infrared spectrums in order to eliminate color casts and ensure cleaner, truer blacks when using this filter, one ACCU-ND Vapor Deposition layer is sandwiched between two layers of optical glass.

This Tokina 4 x 4" PRO IRND 0.3 Filter is constructed from optical glass for clarity as well as color fidelity, and its sandwich design protects the ACCU-ND substrate while the glass surfaces can be re-polished should they become accidentally scratched.

Q: 1. Does this model have a built in speaker?

A: This does not have a built in speaker. You can plug it into external speakers.

Q: 2. This listing is inaccurate? This is an oil base hazer, not a water based.

A: According to Antari, this HZ-350 can use either oil-based or water-base haze fluid. However, they stress that before using one or the other, the machine should be drained completely as the two type of fluids should not be mixed.

Q: 3. What's the difference between this machine and the Z-350 Fazer from Antari? How can I choose between this machine, the Z-350 Fazer and the similarly priced MAGMA Prime 700w haze machine from Elation?

A: The Antari HZ-350 Haze Machine can output up to 2,400 Cubic Feet in 1 Minute. The Antari Z-350 Fazer up to 3000 feet in a minute and the Elation Professional MAGMA PRIME 700W up to 4000 feet per minute. That is the main differences between them.

Q: 4. is this a cd?

A: The software is in a box on a DVD.

Q: 5. How is telescope with light pollution? My Stellina is outside right now under two streetlights taking beautiful pics of the sky

A: The Celestron Origin Intelligent Home Observatory will work in light polluted areas with an appropriate 2 inch light pollution filter.

Q: 6. Can the UniFi Dream Machine Pro be controlled by a separate Cloud Key? I have multiple locations operating, need to add 1 more.
