Planning for my holiday this year- off to Italy in a week. I’ve bought some film- now it’s a question of deciding what cameras to take. So far I’ve decided on 2 120 cameras- a folding Ensign Selfix and a Holga. Also a small 35mm film camera- probably Smena 8M.
Cost here in Moscow- the Kodak 35mm and the Fomapan about a pound or just over per film,(50-60 roubles) the Fujicolour and Kodak Portra about 2 pounds 50 per film( 120 roubles) . I know some people get amazing bargains- this is the most reasonable I have found.

Most of this film was acquired when my local camera store, Cutler Camera, closed up shop last year. The owner gave me about 20 rolls of film for free!
Hidden: 1 roll of Agfa Portrait 160
Not Pictured: 3 packs of Polaroid 665

This works by reflecting the infra-red component of solar energy (often 700W/sq M) and absorbing the UV component. Some films are also silvered or tinted to reduce visible light.
Typical absorption for a silvered film is 65% for visible and infra red with 99% for UV. This type of film sticks directly onto the glass.
Convection control film
Typical window insulation film kit of plastic shrink film (folded-up) and a roll of double-sided tape (see Wikihow installation instructions)
This film is attached to the window frame using double sided pressure sensitive tape. The effect is to create a double glazed system with a still air layer about 0.5 inches thick between the film and the glass. This restricts the convective air flow which efficiently transfers heat onto the inside glass surface. The reduced heat flow also can prevent condensation which is triggered when the temperature of the inside surface falls below the dew point. Assuming an outside temperature of 0C with wind velocity 15mph and inside temperature 20C condensation occurs at only 30%RH relative humidity with a single glazed system compared with 60%RH for a double glazed system. Condensation also transfers an additional 2200 J/ml which is significant.
The film is a heat-shrink plastic which allows a hair dryer to be used to remove creases and improve optical clarity. Since the thermal conductivity of air (0.024 W/mK) is much lower than glass (0.96 W/mK) the heat flow via conduction could be theoretically reduced by 97.5% though this is limited in practice by slow air movement in the convective cell formed between the film and the glass.
However, a typical window insulation film kit will not prevent convection unless the frame is less than 1 inch from the glazing. The top sash of a typical double hung window is 1-2 inches behind the lower sash which is 2-3 inches behind the window frame. This is too far to eliminate convection. In these situations, the kits work by reducing infiltration not convection, and are similar to interior ‘storm windows.’ The ideal distance for 2 sheets of glazing is about .5-.75 inches (refer to insulated glazing).
Applications
Solar control film is an effective way to control excessive sunshine during the summer months.
Convection control film is often used in winter when the outgoing heat flow is more important, especially for single-glazed windows where the temperature difference is often sufficient to cause condensation.

Vs Polysilicon Thin Film Solar Cells Is A Difficult Choice – Polycrystalline Silicon, Thin Film,
Click to see more exciting information
In the energy field, for all semiconductor manufacturers, business opportunities are expanding. This is because, if we can make full use of semiconductors, will be able to raise all kinds of equipment and systems Energy Efficiency.
Inexhaustible solar energy is renewable human energy. Is also clean energy, not produce any environmental pollution. Effective use of solar energy among; large photovoltaic solar energy use in recent years is the fastest growing, most dynamic area of research, is one of the most watched items. To this end, people have developed a solar cell. Solar cells are mainly based on semiconductor materials, its working principle is to use photovoltaic materials absorb light energy in the conversion occurred after the photoelectric response, according to the different materials used, types of solar cells are also different, but regardless of what material to produce batteries , on the general requirements of solar cell materials are: 1, band gap semiconductor materials can not be too wide; to have a higher photoelectric conversion efficiency of: 3, the material itself does not cause pollution to the environment; 4, material suitable for mass production and material properties stable.
China is the world’s largest solar cell manufacturing base. China’s production of polycrystalline silicon solar cells are basically, the main raw material for the polysilicon. Compared with thin film solar cells, polycrystalline silicon photovoltaic solar cells efficient. Thin film solar cell is generally not more than 10%, while most of polycrystalline silicon solar cells for more than 14%. A few years ago, due to shortage of polysilicon materials, the international market price of polysilicon as much as several hundred dollars per ton. In this context, many parts of China launched a polysilicon production line. Resulting in excess capacity, coupled with Financial Crisis, resulting in a sizeable drop the price of polysilicon. Followed, polysilicon and other emerging industries is that “duplication of building orientation.” At the same time, polysilicon production process of the high energy consumption, and silicon tetrachloride and other toxic by-products pollution of the environment, has also been a lot of criticism. As China’s polycrystalline silicon solar cell products are mostly exported to developed countries, it was vividly called “consumption abroad, including pollution.” Wake-up call in the polycrystalline silicon solar cells by the occasion, solar cells, another family member?? Thin film solar cells into the limelight.
China solar cell industry had even in crystalline solar cell production, driven by rapid expansion, in fact, China’s film Si and CIGS thin film solar cells, etc., can also be said as positive. Involved in thin film Si solar cell production of nearly 60 companies. Which not only have to own technology based businesses, but also a package of (Turn-Key) to import equipment to start business enterprises. Over the past few years, production of thin film solar cells in a high-speed increase. According to market research firm DisplaySearch released in the August 11 solar cell production capacity trend reports, in 2009 thin film solar cell production capacity of about 3.58 million kilowatts. We can name suggests, thin film batteries is to prepare a film into solar cells, due to its silicon is extremely rare and therefore easier to reduce the cost. Thin film solar cell is a highly efficient energy products, and more easily with the perfect combination of architecture. Silicon raw materials in the international market against the background of continued tension, thin film solar cells has become the international PV market development trends and hot spots. Broad prospects for thin film solar cells, but does not mean no risk. At present, the thin film solar cell solar cell industry in China, the proportion of only about 10%. The next 10 years to 20 years, thin film solar cells will not occupy the dominant position of solar cells, because the technology is not mature enough.
Although our beginning in 2007 to become the world’s production of solar cells than any other country, but abroad there are many gaps. Moreover, the development of new types of solar cells, our still in its initial stages, but already has great development abroad, therefore, the development of solar cells in China long way to go.

People in Cardiff (and Barry!) are so blasé about film crews nowadays. You automatically think it’s either Doctor Who, Torchwood or Gavin & Stacey.
I’ve no idea what’s being filmed here. I like the woman in the pink suit’s hair-do.
Film Crew in the Camargue

Thursday, August 14, 2008 – The family I live with has a farm in the Camargue. Michel, the gardian of the horses, gave Monika and me a tour of the houses, garden, fields, and marshes. We happened to be there the same days as a film crew who wanted to see the gardians in action, so we watched the cowboys and cowgirls of the Camargue round up the bulls. /
