Aiaxact Wall Mounted Vacuum Easels For Photographing Oversized Fine Art, Posters, Maps, Blueprints And Drawings
Wall mounted vac. easels ARE manufactured by tti for AIA with special wall mounting kit that provides stability, dampen any possible vibration from the vac. easel, and assure a level surface. These vac. Easels also have magnetic surfaces. Each Vac. Easels comes equipped with pump/s, industrial strength hoses and fitting, on/off foot pedal control, and optional variable pressure controllers, and coner and straight magnets.
Standard sizes are: 11X14", 16X20", 20X24", 30"X40", 40"X60" (Custom sizes can be accommodated)
Tips For Using Wall Mounted Vacuum Frames
- Do not use a wall that is directly adjacent to air compressors, other heavy machinery, and elevators.
- After mounting on wall, use a piece of 2X4" wood to create a lip or self under the lower edge of the easel. This can be used in conjunction with the magnet set to position stretched or framed art.
- Drop a plumb line from the exact center of you easel to the floor. Start a roll of Grip tape at that point and bring out in a straight line going as far back as you desire. That line can act as a guide for placing a tripod or dolly type camera stand. With some experimentation you can determine what the placement position for rough focal points would be for specific size art and lens. Lay down across your centerline tape and mark art size/lens size with a Sharpie.
- Nothing can fall on the artwork -- VERY IMPORTANT for museums, etc. Canvas paintings on stretchers will remain much flatter when mounted vertically (for horizontal copying) than when mounted horizontally, where the center tends to sag relative to the edges.
- Larger originals can be accommodated with appropriate focal length lenses -- no need for performance-limiting wide-angle lenses, which have more fall-off, and add chromatic aberrations.
- Easier to deploy (arrange) the lighting, both for standard copy work and for special illumination on certain originals -- artwork is viewed the same way it normally is (on the "wall").
- Easier to see the results of lighting and camera setup, and for camera adjustments than when the camera requires the operator to use a ladder to reach it 72" off the ground.
- May require more space than a vertical copy stand.
- May be more subject to vibration between subject and camera than a vertical stand.
