This 49mm Variable ND Lens Filter Plus+ from Urth provides an increase in neutral density through a range from 3 to 7-stops. Increasing neutral density offers finer control in available shutter speeds or aperture settings for both still and video applications. Using a longer shutter speed makes it possible to increase blur to convey a sense of movement, or to dial in a video camera frame rate. Increased density also makes it possible to shoot using wider lens apertures, helping to isolate a subject from the background. This level of image control can help to create more cinematic effects in low to bright light.

The filter is made from Schott B270 optical glass that features 20 layers of multicoating for reduced lens glare, providing a more consistent transmission curve and optimal light transmission. It also features nano coating on each optical surface that resists water, oil, dust, fingerprints, and scratches, making it ideal for use in harsh environments, and also easy to clean. The rotating aluminum filter ring has a density scale for repeatable results, and a slim design for use with wide-angles lenses without vignetting.

Q: 1. Which exact gels should I buy to counteract the pinkish hue of this light's tungsten setting and the red-pinkish hue of the daylight setting?

A: The light has variable color control. So you need to play with the color control on the light to get it to match what you are shooting in. But that also means you need to set your camera to the correct white balance. You should not be shooting in auto white balance.

Q: 2. 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

Q: 3. I'm abroad and I forgot the original battery charger. Can I use my Bose speaker charger that is Output 17.0V? If so, how long will it take to completely charge the battery?Thanks in advance

A: If the charger you have is compatible with NP type batteries it should be fine. If it is not it is best not to try as that can damage the battery. Also the NP batteries are very specific size and shape. So if the charger is not designed for NP batteries chances are the battery will not fit in the charger to charge.There are many NP battery chargers. If you are near a store that has camera and NP batteries chances are they will have a charger.
