Lens Hood Tube

Tips for Lighting your Kitchen

There are three basic types of lighting. Ambient or general lighting, which provides a soft wash that illuminates a large space; task lighting, which provides illumination to accomplish specific tasks (lights that shines directly on counter tops,) and accent lighting, which focuses light on a specific object or area for aesthetic rather than task oriented purposes.

Planning a combination of these types of lighting is key to kitchen design. Different fixture types each serve a different purpose, so don't go by looks alone. A pendent light hanging low over the table creates an intimate mood for dining. Spotlights or slim fluorescent tubes can be concealed on the underside of wall cabinets, while most cooker hoods are supplied with in built lighting.

Track lights, for example, usually cast defined beams of light. They are great for accenting the center of an island or highlighting collectibles on a display shelf. Track lighting is a good solution when there is not enough space behind the ceiling to install ceiling-recessed down lights. Track lights, however, usually do not provide adequate general lighting.Decorative task lighting is a great way to provide light over an island. Lighting controls can be installed to change light levels to suit the tasks at hand.

Lighting affects not only your ability to perform tasks but your mood and the way the objects and materials in the kitchen are perceived.With new technological advancement you can specifically choose how much light you want in each area.You can for a 3D view of your room.The calculation of lighting is done as per physics and so you know exactly know how much light you need and of course the design that will gel with your Kitchen.

Extension tube....this may sound stupid?

do you have to have a specific tube for the mm of the lens

in the same way that you have to have a specific lens hood for the mm of the lens otherwise the image may have the sides of the lens hood in it

does this also apply to extension tubes, or are they all compatible with all lenses (as long as it fits the mount: canon mount, nikon mount etc)

??????????

you need to get a tube, specific to the camera you are using ...

If you are using a Canon... the Canon extension tubes will work with both the EF and the EF-S lenses. Off brand tubes, will not work with the EF-S lenses.

The tube mounts between your camera and the lens... you don't need to concern yourself with the mm of the lens as far as fitting is concerned.

You can also stack the different size tubes, to increase the maginification factors.
