History - Photoshop

Adobe Photoshop is the market leader in photo editing software. Originally designed by John and Thomas Knoll in 1987 for the Macintosh, the program has grown into the industry standard for computer graphics today. Many of the most well-known features of graphics programs in use today were originally pioneered by the Photoshop system.

The first full release of Photoshop was under the Knoll Software name, before they completed their partnership with Adobe. The first edition of Photoshop, including the manual, fit on an 800k floppy disk with room left over. The Macintosh computer was the only place you could run Photoshop, from the first release in 1990 until version 2.5 was finally released for the PC world in 1992.

One of the real power features of Photoshop has been modular design. The programmers wanted to be able to make changes without altering the core engine, and along the way, they opened the ability to create filters and add-on modu0les that greatly expanded the power of the program.

Photoshop continued to add new features and power over the years. Layers were added to the program in 1994. Macros and adjustment layers arrived in 1996. 1998 saw the invention of the Magnetic Lasso and the addition of the History palette, which allowed for undoing several actions, not just one. The Healing Brush, a powerful cloning tool, was added to the lineup in 2002, as well as the first support for the RAW format.

Version CS2, released in 2005, has a variety of new feature, including red-eye correction, lens correction, HDR support, and the latest revision of support for the RAW format.

Photoshop is so well known that it's name became a verb, much like Google has done. However, since Adobe would like to protect the copyright on Photoshop, many websites have slightly changed the phrase to "photochop" instead.

History of headphones

History of Headphones

Headphones have changed a lot over the years. One hundred years ago they were just single earpiece that was held tight against one ear and was the only way to listen to transmitted sound.

This was before the great invention of the amplifier. Headphones were used in radio stations and not for sale to the public.

Things have changed and there is just about no one out there that has not heard of headphones. They have increased in popularity along with mobile phones, MP3 players and Ipods.

The most popular used wires to connect the headpiece to the equipment and then did not let the consumer move around with a limited range. Meaning that you could only go as far as the wire would reach.

The invention of the wireless headphones was a great way for people to do what they need to do while listening to what they wanted.

The Blue tooth invention has also given the consumer great freedom. The headset hooks on to the sound by being transmitted from up to ten meters away.

Most people carry the transmitter, known as a mobile phone with radio or MP3 player; the distance is not a real problem.

Think about being able to move around and do what you want in your house or office plus listening to your favorite music without interrupting others.

The best part about the headsets of today is that you will get great sound. You will not have outside noise bothering you at all.

You are in a great world of technology because you can listen to music while running or just sitting around your bedroom.

History of photo faking

History of Photo Faking

Almost as soon as the first photographs came out of cameras, people were using them to manipulate images.

Take, for example, the very famous portrait of Abraham Lincoln, standing with one hand on his desk. Analysis in the 20th century showed that his mole was on the wrong side of his face, and further research turned up a picture of North Carolina Congressman John Calhoun in exactly the same pose. Someone in the 1860s had taken Lincoln's face and pasted it onto Calhoun's body, and the resulting fake photo was spread all across the Union.

Through the Civil War, photo staging was much more common than photo editing. It was very difficult to get an "action" shot because of the long exposure times, so war photographers would pose their shots.

Later, through the early twentieth century, photo postcards showing monstrous fish, grasshoppers, and crops were very famous, and nearly all of them were made by merging two shots into the same frame. As the Dust Bowl ruined crops, the postcards of apples the size of watermelons and corn cobs as big as fireplace logs showed a very dark humor--almost a sick joke.

Josef Stalin made photo editing famous, as those who fell out of favor simply "ceased to exist." There are numerous examples of pictures where people standing beside him have simply been painted out and forgotten.

Even magazines and newspapers today are not immune. One magazine over-darkened OJ Simpson's mug shot for it's cover, making him appear much darker and more menacing than he was in real life. And a number of photojournalists were caught using Photoshop tools on their photos to either merge two scenes into one or increase the smoke and battle damage far beyond what was really there.

Photo faking goes beyond simply posing a scene, because it's a blatant attempt to lie to the viewer.

History of solar energy

History Of Solar Energy

When people talk about solar energy, a lot of people think of certain solar energy sources that are pretty common to them, such as wood, and even dried animal droppings. Aside from these possible sources of solar energy, people also associate the concept of solar energy as one of the possible causes for global warming.

However, there are still a lot of things that people do not know or fully understand about solar energy just yet, like what it is exactly, and how to use it to its utmost potential. In order for you to fully understand more about solar and sustainable energy, and what the future holds for it, you need to learn more about the history of solar energy. This article will give you a chance to delve in deeper into solar energys fascinating history.

Historical Role Of Solar Energy

One of the more common and more popular roles that the sun, or solar energy, played during those ancient times is that of a force that is able to sustain life based on its ability to give off renewable energy. This is probably the main reason as to why the people during those times, especially in native South and North America, as well as in other parts of the world, worshipped the Sun.

Ancient Greece built temples devoted to worshipping their sun deities, namely, Helio and Apollo. Also, the Greeks use of solar energy were not limited to religious purposes, as they even used the solar energy system to incorporate passive solar design in the construction of their houses.

The Romans simply improved the Greeks design and also incorporated windows into their structures, allowing them to be able to trap more solar heat. This actually played a role in their ability to produce a good growing condition for plants.

Solar Hot Water Heater Prototype

Unknown to a lot of people, but the original prototype for solar hot water heaters is actually a result of do-it-yourself projects of people in their hopes to be able to boil water, and keeping the water hot for a longer period of time. Scientists during the 18th century were able to discover that covering a box with a glass top while heating it would actually get the water to reach boiling temperature. But it wasnt until someone tried to separate the solar heat collector with the water tank that the first prototype for solar hot water heaters was created.

Discovery Of Solar Energy Cells

Solar energy cells, also known as PV cells, are actually created when three Americans discovered that building transistors with silicon. This was during the 1950s. PV cells werent actually an affordable solar energy source back then, however, due to its practical use in the satellite industry, the solar energy cell industry became sustainable. PV cells serve as the main fuel source for satellites out in space.

Solar Energy Today

Nowadays, in our more technologically advanced times, solar energy has now garnered a lot of renewed interest and focus, especially since solar energy has now become more affordable, and offers more use and application in our modern day needs. Solar energy cells are actually being used in a lot of businesses and homes today, and are even responsible for powering most household appliances, office equipments, and are even used to power cars.

History of racing pigeons

History of Racing Pigeons

Today's generation is fortunate enough to experience the wonders of modern communications. Letters are electronically sent in a matter of seconds via the Internet, and real time conversation with colleagues from far away is now possible through Instant Messaging.

Ah, thanks to technology. Did you ever wonder what was it like a thousand years ago, when ancient man was still one with nature and empires were just about to be built? Tribes communicated with each other through pigeons, and the racing pigeons were animals that were revered by many because of their speed and agility.

The great civilizations from East to West made full use of the racing pigeons as messengers that deliver important messages coming from the emperors out to the most remote areas of their lands. As empires expand, more and more racing pigeons were sent out to the sky.

Because of their intelligence and swiftness, racing pigeons were regarded as prized possessions during the ancient times. Just imagine empires having only horses and caravans as their message-carrying tools. It would take weeks before messages can be exchanged from one area to another. Animals that travel by land are also more prone to danger, especially during warfare.

One famous incident in history where racing pigeons proved their worth was when Napoleon was defeated in Waterloo. No other person knew about this event right away, except for Count Rothschild, who got this first-hand information through a racing pigeon. This knowledge enabled Rothschild to make decisions way before other persons had a chance to meddle. He was able to collect a large amount of money to start up a banking dynasty.

Racing pigeons were not only used as an important military weapon. During the Industrial Revolution when people started to revolutionize their way of thinking, racing pigeons were used as news-carriers not to aid a war, but to keep people informed about the society. Julius Reuter, the founder of the world-renowned Reuter News Service, was actually established as a line of pigeon posts. Up to this day, the symbol for many European postal systems is a racing pigeon.

As years go by, a lot more people have taken to raising pigeons. Gone are the days when only the nobles can have them. Most of the time, these birds are seen with racing enthusiasts, with the birds as the main attraction.

The most successful modern racing pigeons were developed in Belgium. They were a result of a cross between the Cumulet and the Smerle. The Cumulet is often described as a pigeon that has the ability to fly high and can be gone out of sight from the sky. The Smerle, on the other hand, doesn't fly as high as the Cumulet, but is much faster and hastier.

It's no surprise that the Belgians were the ones who first enjoyed the hobby of pigeon racing. The first long distance pigeon race was in Belgium in 1818. After 1875, the hobby of pigeon racing gained popularity in England. In the 19th century, the popularity of the hobby reached the United States.

Today, the world continues to be enthralled with the speed, endurance and the intelligence of racing pigeons. Amidst the technology that we have today, these pigeons still surely know how to get our fancy.
