light, photo means light. Photograph - light picture (roughly) photosynthesis is synthesis of energy (glucose) from light
The photo in the word photosynthesis means light. Plants use light as part of the food-making process. Carbon dioxide is another major input during the process.
once you get marshalls badge you go to the photo booth and when you take the picture make sure your cursor is on the photo not moving for wild wild west.
The light-dependant reactions are the photo- part of photosynthesis.
Gold parting or parting process is the separating of gold from silver. Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to …separate. Processes involving in parting of Gold. Salt cementation This process was used from Lydian to post medieval times. It is a solid state process relying on common salt as the active ingredient but it is possible to use a mixture of saltpetre (KNO3) and green vitriol (FeSO4). The basic process involved the mixing of argentiferous gold foil (in later periods granules were used), common salt and brick dust or burnt clay in a closed and sealed container. Theophilus mentions the addition of urine to the mix. With heating, the silver reacts with the salt to form silver chloride which is removed leaving a purified gold behind. Conditions needed for this process are below 1000°C as the gold should not melt. Silver can be recovered by smelting the debris. Heating can take 24 hours. Hoover and Hoover explains the process thus: under heating salt (sodium chloride, NaCl) decomposes in the presence of silica and alumina (from the brick dust or clay) to produce hydrochloric acid and also some chlorine. This reacts with the silver to produce silver chloride (AgCl). The urine is acidic and aids decomposition. Silver chloride is volatile and would be removed from the metal. And the container is sealed to stop the escape of the silver which can be recovered later. Notton in experiments found that with one heating the gold content could be taken from 37.5% to 93% Sulphur and antimony processes This is similar to the salt cementation process but creates sulphides instead of chlorides. Finely divided impure gold and elemental sulphur are reacted together under moderate heat in a sealed crucible. The impurities form metal sulphides and the gold is left unreacted. The gaseous sulphide condenses on the crucible fabric. The antimony process is the same but uses stibnite (Sb2S3) instead of sulphur because stibnite is stable at a higher temperature than sulphur. This is much quicker than the salt process and gave a purer gold, but it could dissolve some of the gold as well. This process is first described in the Probierbuchlein. Acid parting Pure gold precipitate produced by theaqua regia refining process The distillation was used in the 12th century Europe after its introduction from the East and after that period more powerful acids could be created. Nitric acid (aqua valens) could be made by the distillation of saltpetre (KNO3) with alum (KAl(SO4)2) or vitriol (FeSO4) with water. 2KNO3 + H2O + FeSO4 → FeO + K2SO4 + 2HNO3 Nitric acid, after distillation to increase the acid strength, was capable of dissolving the silver from a finely divided mixture of silver and gold, leaving the gold. Aqua regia was also used for parting. It was made by adding sal ammoniac to nitric acid which produced a mixture of hydrochloric acid and nitric acid. This acid dissolved the gold to a soluble chloride and the silver was attacked and precipitated as an insoluble chloride. Silver was removed by filtering and gold was then recovered by evaporating the liquid and heating the residue. Nitric acid was suitable for separating small quantities of gold from silver and Aqua regia used to separate small quantities of silver from gold. Miller processThe Miller process was invented by Francis Bowyer Miller in 1860's Australia. It is able to refine gold up to 99.5% purity. The process involves blowing a stream of chlorine gas over and through a crucible filled with molten impure gold. Impurities in the gold form chlorides before the gold does and these insoluble salts are removed from the melt by skimming the surface. Wohlwill processInvented by Emil Wohlwill in 1874 this produces the highest purity gold (99.999%). It is an electrolytic process using pure gold for the cathode (or titanium as a starter cathode) and chloroauric acid (gold chloride-hydrochloric acid) as the electrolyte; this is made by dissolving gold with chlorine gas in the presence of hydrochloric acid. Gold is dissolved at the anode, and pure gold, traveling through the acid by ion transfer, is plated onto the cathode. Silver forms an insoluble chloride slime and copper and platinum form soluble chlorides that are removed. This procedure is used on a very large industrial scale and has a large set up cost due to the amount of gold that needs to be permanently dissolved in the electrolyte. ElectropartingElectroparting is recent gold refining procedure where gold is separated from other metals in electrolytic cell in a way that dissolves all metals except gold and platinum. This procedure refines gold directly, producing up to 99.5% purity gold powder in a single step.

no it is impossible
It depends! If you say "this is a photo opportunity!" then it is an adjective in that case. If you say "Quick! Take my photo!" then it is a noun.
Not all photo processing photos are water resistant, but there are some that are. For example, HP does offer such an option. Be sure to know your product.
Kodak and a few other companies actually make a kind of paper to print photos on. It's called photo print paper. You can print it on this,and cut around it and it feels just l…ike a picture.
Film and paper are needed to begin the process. These must be dipped into several chemical baths. Some processes then use equipment such as squeegees or rollers.
Photos are the important part of social media because photos can easily give so much infomation, also include emotion from people to people. Everything can be provided with an… photo.
Online photo printing uses the process of sending photos (usually .jpegs) to a specific print site. That company either prints it on site or send it out. Customers may have th…e option of picking their photos up directly or having them delivered to their home.
The correct procedure for photo processing is to soak the film in developing fluid inside of a dark room. After taking the film from soaking it is dried and placed into a mach…ine that projects the iamge onto the paper. After the image is burnt onto the paper, that paper is moved into a bath of developing fluid into the picture appears. Then they are hung to dry.
