    dome camera
  • A type of camera with dome cover. They may have fixed or vari-focal lenses. Some come with infrared lighting and some are designed to be tamper-proof (also referred to as vandal-resistant). Armor dome cameras are designed to resist vandalism by using a hi-impact reinforced polycarbonate dome casing.

  • (irs) Internal Revenue Service: the bureau of the Treasury Department responsible for tax collections

  • Infrared

  • Inland Revenue: a board of the British government that administers and collects major direct taxes

  • iridium: a heavy brittle metallic element of the platinum group; used in alloys; occurs in natural alloys with platinum or osmium

About Infrared Photography:
In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Usually an "infrared filter" is used; this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum (the filter thus looks black or deep red).

When these filters are used together with infrared-sensitive film or sensors, very interesting "in-camera effects" can be obtained; false-color or black-and-white images with a dreamlike or sometimes lurid appearance known as the "Wood Effect," an effect mainly caused by foliage (such as tree leaves and grass) strongly reflecting in the same way visible light is reflected from snow. There is a small contribution from chlorophyll fluorescence, but this is marginal and is not the real cause of the brightness seen in infrared photographs.

Digital camera sensors are inherently sensitive to infrared light,[15] which would interfere with the normal photography by confusing the autofocus calculations or softening the image (because infrared light is focused differently than visible light), or oversaturating the red channel.

Depending on the subject matter, infrared photography may not be practical with these cameras because the exposure times become overly long, often in the range of 30 seconds, creating noise and motion blur in the final image. However, for some subject matter the long exposure does not matter or the motion blur effects actually add to the image. Some lenses will also show a 'hot spot' in the centre of the image as their coatings are optimised for visible light and not for IR.











Jon and Carrie Carr




Jon and Carrie Carr





I photographed Jon and Carrie for their Christmas Card. I suppose I should also add 'and baby Carr'. Great timing to have the baby bump.

Strobist info: SB-900 with diffuser plate down and diffusion dome on in to 60" Impact white reflected umbrella camera left and above. SB-800 into 45" white Impact shoot through umbrella camera left and behind for rim/ hair light. SB-600 in 43" white Wescott shoot through umbrella camera right and behind for hair/rim light. Triggered with pop up commander with IR pass through filter.
