Inadequate lighting is an ongoing problem for an increasing amount of people, due to the prevalence of smartphones today. Whether taking a picture with your smartphone or an SLR camera, lighting is everything. Professional photographers use artificial lighting techniques to control light temperature and to emphasize the shapes of objects.
Having conducted research in the area of artificial lighting for photography, the design parameters for this light design were set through the limitations usually set when following standard lighting techniques. Portraits are a common subject for photographs, and seting light above the subject at a 45 degree angle will improve lighting in pictures.

Propper diffusion is important. Initial sketch models of the light shades were created using paper and origami folding techniques. Using Mylar paper created appropriate light diffusion, but was not stiff enough to hold up to the changing of light bulbs. HDPE sheet was cut frrom a template to create the final reciprocating diffuser.
Tubular steel was bent on a ring roller. the feed was offset to create a spiraling ring of tubular steel. holes for the Colorcord wire were drilled with a stepped drill bit and a grinder.
The final templates were cut from a 1/16th thick sheet of High Density PolyEthyline (HDPE). The HDPE shades are screwed to the turned ash housing with screws fastened with threaded nuts.

Aside from gluing the ash into a cylinder before turning on thte wood lathe, there is not glue used in the assembly of the luminaire. This is to facilitate future packing and shipping of the lamp, if itt were to be brought to market.
f the Photogenic Luminaire were to be brought to market, it could be manufactured more cost effectively by using a custom spindle that carves out the form of the ash housing without requiring the operator to carve out the shape freehand with a reference. Turning the ash housings allows sanding on the lathe, which shortens preperation time for finishing.
Bottom first image: Different width and radii for the lamp are made quickly on the ring roller and testing for appropriate scale and proportion while sketch modeling in actual scale. Hanging the tubular steel from tweed wire aided in assessing the spans for the electrical wire.
