Shutter speed are both technical and aesthetic choice a photographer needs to make before releasing the shutter.

Daguerrrotypes photographs were invented by Louis Daguerre and Nicéphore Niépce. The process to make Daguerrotype images was first they started of with a polished metal plate covered with silver iodide which is a light sensitive compound. The plate exposed to the light was then exposed with warm mercury vapor which helped develop the image on the copper plate. John Herschel was the inventor of cyanotype.Cyanotype is a photographic printing process that produces a cyan-blue print. Engineers used the process well into the 20th century as a simple and low-cost process to produce copies of drawings, referred to as blueprints. The process uses two chemicals: ammonium iron(III) citrate and potassium ferricyanide.Cyanotype Formula:Solution A: @5 grams of Ferric ammonium citrate (green) added to 100 ml water.
Solution B: 10 grams of Potassium ferricyanide added to 100 ml water. In a darkened room (no UV) mix equal parts of solution A and B. The solution is now light sensitive and should be used immediately and stored in complete darkness. In the same darkened room coat a piece of watercolor paper(90 pounds works well) using a small paint brush and dry the paper using a hair dryer. The paper be stored in a light-tight box for later use. Using the contact printing method expose the paper to full sun for 15-20 minutes. The yellow emulsion should turn to a steel bus gray color. Exposure times vary greatly depending upon the strength of the UV source and the density of the negative. Artificial light sources rich un UV may be used with testing. The UV light reduces the iron(III) to iron(II). This is followed by a complex reaction of the iron(II) complex with ferricyanide. The result is an insoluble, blue dye(ferric ferrocyanide) known as Prussian blue. A group of friends met at a restaurant and one of them had the idea to race their cars since they were all fast. They didn't know where to race but one of them remembered there was an abandoned airport where they can race. They went to the airport where they later made themselves aligned with each other. To make the race more intense they thought should race for $500 meaning who ever is first goes home $1000 richer. When the race started the grey had an advantage because the other two car's wheels were burn in g rubbing. The green car told to himself that he was gonna win because he had a muscle car and it would eventually catch up to the the grey car and win the race. Meanwhile the red car thought he already lost because his car was made for off-road. And the grey car started to be cocky and told his friends on the phone "thanks for the money" before he even made it to the finish line. The grey car later looked back to see how far back his friends were and when he turned back his arm made a sudden jerk make his car swerve a little. When he looked back at the road his arm made another sudden jerk make his car go out of control. He was trying to take back control of his car but he couldn't and he swerved into the red car. He thought he as going to crash into his friend but his friend swerved him and went faster. And out of instinct the green car made a U-turn to go check on his friends. When he did the U-turn he didn't notice that his friend nearly missed his other friend from when he lost control of his car. He saw the red car fly right by him and making the guy with the red car way in front of them. The guy in the red car said "see ya wouldn't to be ya" when he crossed the finish line.
The aperture difference shows how much of an object is in focus compared to other objects around it. The aperture of f1/1.8 mainly focuses on the first box and it blurs out the other two boxes. With an aperture of f-8 it focuses on the first box but it doesn't blur out the second box meanwhile the third box and background is blurred out. And with an aperture of f-16 all three boxes are in focus with very minimal blur that's noticeable.
Digital Camera Basics
Camera obscura is when a dark room or box gets a small beam of light from outside and reflects the objects outside upside down. The light from outside acts sort of like a projector. This eventually led to the start of cameras.
