Chapter four in A Short Course in Digital Photography discusses the technology that occurs after photographs are taken and before photographs get printed. The chapter goes into showing the equipment that is used to help edit and print digital photos such as, a computer and monitor, and a printer. Looking further into this side of digital photography, the chapter also explains the certain image files that pictures can be taken or formatted in depending on the file name extension. A lossy is a term that accounts for compression each time a file is used in editing and then is re-saved. A lossless is when nothing is lost from the file after editing. A higher bit rate allows for more editing without compensation for other factors such as file size. A gamut is the total of all the colors a camera can accept or make. The channels are the layers in a photograph that make up the colors in a color photograph. A channel can go through a whole gradient of a certain color. A 2.2 gamma and a D65 white point should be used unless instructed otherwise. A speed of a memory card is important because it shows the rate at which files can be transferred. A vital component to this part of the chapter is to make sure pieces of electronic technology like memory cards and a digital camera itself are not exposed to extreme heat or extreme cold because these two contributing factors could lead to rendering the electronic malfunctioning or useless. It is also important to keep areas clean and organized to reduce risk of damage to electronic devices and photo prints as well as to maintain an orderly, clear system of getting tasks done to reduce future confusion and time waste.
The corresponding link (below) to this photograph goes through the history of Adobe Photoshop and how the Knoll family created the first photo editing software known to man. February 1st, 1990 marked the day Adobe 1.0 was released. Happy Belated 25th Birthday, Adobe! I'm not that old I guess.
