LIGHT PAINTING A” how to” to getting started. WHAT IS LIGHT PAINTING Light painting, or light drawing, is a photographic technique where a photo is created by moving a hand-held light source using it as either direct light source or to illuminate a subject while taking a long exposure. You can also have a stationary light source and move the camera for light painting effects. WHAT’S NEEDED TO LIGHT PAINT • Camera. • Wider angle lens, 18mm-55mm, 24mm-70mm, etc. • Remote trigger that works with bulb mode. • Tripod. • Light source…..flashlight, candle, lantern, flame, sparklers etc. • Some darkness. • Dark clothing. CREATING THE SHOT • Pick your site, something of interest. • Walk through in your mind what you want to do and pick the appropriate tools. Give it some thought! • Set up camera and choose your settings . Camera in bulb mode. ISO: starts at 100 f/stop: start at f/5.6 – f/7.1 Exposure setting Matrix or Evaluative. • Shine light on your subject, frame your composition and focus, auto focus is OK. Remember to leave enough room to light paint. You can always crop later • Turn off your auto focus or use back button focus. TOOLS • Universal adaptor. • Light swords. • Light blades. • Light pens, light writers. • Fiber optics and fiber optic whips. • Light sticks, light wands. • Light hoops. • Light strings, fairy lights. • Plastic bottles, florescent bulb covers, colored gels. FLASHLIGHT TYPES • Can go as low as 100 lumen for direct light painting or close up illumination. • Recommend 700-1000 lumen with a Cree led (square yellow chip) and 18650 battery to illuminate subjects that are farther away. Also to light paint in lighter surroundings. • Dimmable or multi brightness levels. • Zooming or focusing. • Warmer whites are best for color reproduction.

Design and Fabrication of Evacuated Tube Solar Thermal Collector for Domestic Hot Water
JOURNAL OF COLLEGE OF EDUCATION….. 2016…….NO.3 Design and Fabrication of evacuated tube solar thermal collector for domestic hot water Dr. Alaa H. Shneishil Al-Mustansiriyah University, College of Education, Physics Department ABSTRACT The objective of this research is to design and fabricate solar water heating system by Investment defective materials in Iraq for domestic sector applications in order to encourage national industry. Defective neon light tube with length 120 Cm and diameter 3 Cm has been used as an outer pipe. Copper pipe with length 125 Cm and diameter 1 Cm is placed inside the glass tube and close the space between them by circular shell that is used as an inner absorber material after painting it by black non brightness coating. The space between the outer glass tube and the inner copper pipe is evacuated by using small compressor. The evacuated tubes are connected from the upper side with insulated storage tank and from lower side with circulation pump. The evacuated tubes are placed in the focal line of reflective surfaces. The efficiency of the fabricated solar collector has been measured and compared with uninsulated storage tank which put in the same conditions. These measurements are done with and without reflective surfaces. The results indicated that the temperature of water in the evacuated tube with reflective surfaces reach to 59.5 °C while in the evacuated tube without reflective surfaces reaches to 44.3 °C. The temperature of water in the evacuated tube without circulation pump reach to maximum value which about 85.3 oC. This value is greater than that of the case with circulation pump.

Commons House Community Features Mailboxes in the lobby (students still have CPO boxes) encourage unintentional bumps when residents pick up mail. Glass doors allow residents to look inside to see what's going on. Community room is for most meetings and programs - for meetings of the entire community, the Folk Center across the street has low rental fees and we felt we didn't need to duplicate a space of that size with a commercial kitchen. The "kid room" allows children to have their own area during meetings or when parents are doing laundry. Laundry room has washers for residents of original apartments and dryers for use by all residents. Newer apartments have washers but not dryers to make using dryers a choice not an automatic assumption. Examples of re-use Barn siding on outside is from an actual barn. Wood for ceilings came from a house. Carpet in kid room and office is from recycled fibers.

Troy Paiva's Lost (And Found) America
Late Delivery: One of Paiva’s workshop students brought this doll to a junkyard shoot and Paiva says he “fell in love with it” and ended up carrying her around as a prop all night. This was shot just after 2AM with a Canon 60D and a Tokina 12-14mm zoom (at 12mm). The exposure (at ISO 200 with the white balance set for 3800K) was 178 sec at f/8. The overall lighting was from the full moon and the warm white, lime and red set lighting was from a ProtoMachines flashlight. with the ecstasy of creation.” While the technique of light painting has been around since the beginnings of photography, Paiva uses a skillful and experimental combination of moonlight (he works exclusively by the light of the full moon) and handheld lighting tools to reimagine and expand the parameters of light painting and night photography. He has published two books of his work: Lost America: Night Photography of the Abandoned Roadside West (Motorbook International, 2003) and Night Vision: The Art of Urban Exploration (Chronicle Books, 2008). His images have been used to illustrate countless magazine articles and dozens of book and CD covers— perhaps most notably the iconic images on the cover of Stephen King’s books Boxy But Safe: A Volvo station wagon hangs in the jaws of a massive junkyard-shearing machine. Paiva shot the scene in a California auto graveyard with a Canon 60D and Christine and From a Buick 8. a Tokina 12-24mm zoom (at 12mm). He exposed the scene for 167 sec at f/8 (at ISO 200, with the white balance set at 3800K).

PHYSIOGRAM / Light Painting
PHYSIOGRAM / Light painting Light painting, or light drawing, is a photographic technique in which exposures are made by moving a hand-held light source while taking a long exposure photograph, either to illuminate a subject or to shine a point of light directly at the camera. Light painting / PHYSIOGRAM Light painting (also called light drawing) dates back to 1889 when Étienne-Jules Marey and Georges Demeny traced human motion in the first known light painting “Pathological Walk From in Front”. Light painting / PHYSIOGRAM A variety of light sources can be used, ranging from simple flashlights to dedicated devices. Fiber optic light pen, candles, fireworks, lighter flints, glow sticks, and Poi are also popular. Light painting / PHYSIOGRAM A tripod is usually necessary due to the long exposure times involved. Alternatively, the camera may be placed on or braced against a table or other solid support. Light painting / PHYSIOGRAM A shutter release cable or self timer is generally employed in order to minimize camera shake. Color gels can also be used to color the light sources.

Bokeh has been defined as "the way the lens renders out-of-focus points of light".[6] However, differences in lens aberrations and aperture shape cause some lens designs to blur the image in a way that is pleasing to the eye, while others produce blurring that is unpleasant or distracting—"good" and "bad" bokeh, respectively.[2] Bokeh occurs for parts of the scene that lie outside the Coarse bokeh on a photo shot with an 85 mm lens and 70 mm entrance pupil diameter, which depth of field. Photographers sometimes deliberately use a shallow corresponds to f/1.2 focus technique to create images with prominent out-of-focus regions. Bokeh is often most visible around small background highlights, such as specular reflections and light sources, which is why it is often associated with such areas.[2] However, bokeh is not limited to highlights; blur occurs in all out-of-focus regions of the image.
