The fuji 18 55 filter sizefrom fuji 18 55 filter sizeis compatible with a LEE Filters SW150-series filter holder. This filter can be applied to create a warm cast over specific areas of an image, such as a hazy or colorless sky, while allowing for a normal, unaffected exposure in the other regions of the image. This effect can be obtained under daylight when this filter is used on a film camera system with daylight film installed, or on a digital camera system with its daylight white balance setting selected. This filter's partial coloration corresponds to an ability to partially reduce 3400K color temperatures to 3200K, which reflects a mired shift value of up to +18 that can be applied to other starting color temperatures as well. This feature is most pronounced at the edge and tapers to clear by the middle, with a hard-edged line of transition between the colored and clear areas.

This filter is non-coated and is constructed from optical-quality resin for clarity as well as color fidelity. Where its coloration is most pronounced, the LEE Filters 150 x 170mm SW150 Hard Edge Graduated 81A Filter has a 0.1 density with a 1.25x filter factor that darkens the corresponding area of an image by 0.3 stops. This reduction in exposure can be compensated for by adjusting the aperture setting of the lens it is placed on, or the shutter speed of the camera being used.

The greater the color temperatures they can potentially reduce to 3200K, light balancing filters are considered to be progressively stronger in their effect when used to add warmth to a daylight image.

Q: 1. Will this work on top of the RRS Universal Leveling Base with Platform?

A: Yes it will, but not sure why you would want to do this. The BH-55 has it's own level on it.

Q: 2. I'm curious of any recommendations for a tripod that can be used both for photography purposes, but also have the ability to mount a motorized astrophotography tracking head to it at a later time? Id rather splurge on the tripod, being I'd use it for both. Id like it to be backwards compatible with either / or, multiple types of head options (basically be as future proof as it could be). Any advice would be really appreciated! Budget, midrange, and top of the line suggestions would be awesome! Id end up buying a higher end ($1000-ish) tracking head. Willing to hear what else you all suggest! Thanks

Q: 4. What is the mounting screw used for?

A: The mounting screw would be 3/8" female screw opening.

Q: 5. Can the release plate be replaced with the Manfrotto RC-4 plate?

A: No it won't work, I just tried it on mine. The RC-4 plate is too wide for the RRS clamp and it has a profile that doesn't match up with the Arca Swiss style of the BH-55 Screw Clamp. I still use my Manfrotto systems, but prefer the RRS for heavier gear like a full size camera with battery grip and a big lens.

Q: 6. My BH55 pan lock knob is stuck, and the base is unable to be locked into place. Is there a way to free the knob?

A: If it were me, I would get my water pump pliers, tape the jaws, use a cloth over the knob, and GENTLY move clockwise. That should do it. However, this action is at your own risk for it may not work and could possibly mar the finish as well as void the warranty.
