Essay about Macro Photography: Special Techniques

Concept 6.1 Biologists use microscopes and the tools of biochemistry to study cells 1. The study of cells has been limited by their small size, and so they were not seen and described until 1665, when Robert Hooke first looked at dead cells from an oak tree. His contemporary, Anton van Leeuwenhoek, crafted lenses and with the improvements in optical aids, a new world was opened. Magnification and resolving power limit what can be seen. Explain the difference. Magnification is the ratio of an object’s image size to its real size. Resolution is a measure of the clarity of the image; it is the minimum distance two points can be separated and still be distinguished

For everyday pictures, you can mix things up by telling a story with your photography. Instead of snapping pictures as they happen with no influence on the shots, this style of photography involves planning and executing your vision. The storytelling is completely up to you.

The illuminating parts of a microscope enable us to see the detail of the subject placed under the microscope. The three main parts that enable us to do this are: the condenser which illuminates the object that is placed under the microscope, the objectives which forms the magnified image, and the eyepiece which enables us to see the magnified

In electron microscopy, on the other hand, a beam of electrons with a negative charge, instead of light is sent through a very thin slice of the specimen.  Because the electron beam has a far smaller wavelength than light used in light microscopy, it achieves far better resolution, “the current resolution of limit of the best electron microscope is approximately 0.05 nm atomic resolution, and 4000X better magnification than that of a conventional light microscope”(BSP, S., 2010).  This means that with an electron microscope you can potentially achieve enough magnification to observe the shape of the protein machinery that carries out the work inside of cells. The major limitation of electron microscopy is that specimen

It was then during the 1950’s that Zacharias Jansen and his father, Han Jansen, created the first high-powered compound light microscope. Images could be magnified up to 9x which was a novel feat at that time. Zacharias and his father created the device after experimenting with glasses and discovered that by placing multiple lens in a tube they could increase magnification. Unfortunately, the microscope lacked the high resolution we have come to expect in modern-day light microscopes. The images produced by the Hans’ primitive microscope was extremely blurry and had limited

What we consider the modern microscope can be traced back to Holland in the 1590s. Hans and Zacharis Jensen, a father and son team of spectacles makers, are usually listed as the original inventors. Their microscope was simple by today’s standards; it included three sliding tubes with lens at both ends that opened up to eighteen inches when fully extended. The magnification power was generally considered to be about nine times. Even though the objects were magnified, they were blurry. Croft, the author of Under the Microscope: A Brief History of Microscopy, explains that the early devices had severe chromatic aberrations, which consist of color halos surrounding the object making clear viewing problematic. Over the course of the 17th and 18th centuries vast improvements occurred in the field of microscopy including magnification, size, and clarity. Microscopes were to become more portable, and less expensive allowing them to become a instrument commonly found in drawing

Art critic Robert Hughes once said, “People inscribe their histories, beliefs, attitudes, desires and dreams in the images they make.” When discussing the mediums of photography and cinema, this belief of Hughes is not very hard to process and understand. Images, whether they be still or moving, can transform their audiences to places they have either never been before or which they long to return to. Images have been transporting audiences for centuries thanks to both the mediums of photography and cinema and together they gone through many changes and developments. When careful consideration is given to these two mediums, it is acceptable to say that they will forever be intertwined, and that they have been interrelated forms of

Since its inception, photography has been used to capture moments in time all around the world. This wonderful technology has existed since ancient times, and has only improved in recent history, changing society in the process.

The name "Photography" comes from the Greek words for light and writing. Sir John Herschel, was the first to use the term photography in 1839, when he managed to fix images using hyposulphite of soda. He described photography as "The application of the chemical rays to the purpose of pictorial representation". Herschel also coined the terms "negative", "positive" and "snapshot".

When going for a walk, a person takes in the beauty around them. On this particular day, the refulgent sun is extra bright, making the sky a perfect blue. White, puffy clouds fill the sky, slowing moving at their own pace. The wind is peacefully calm, making the trees stand tall and proud. There is no humidity in the air. As this person walks down the road, they see a deer with her two fawns. The moment is absolutely beautiful. Moments like this happen only once in a great while, making us wanting to stay in the particular moment forever. Unfortunately, time moves on, but only if there were some way to capture the day’s magnificence. Thanks to Joseph Niépce, we can now capture these moments and others that take our breath away. The

What is a photograph? The simplicity of taking a photograph leads many to ponder its artistic value. Yet, it is undeniable that there are some photos that cause an emotional reaction deeper than simply observing a recorded point in time. Surely, there are photographs that cause more reaction than some modern art pieces. There seems to be two types of photographs. The first classification is the ‘time capture’ photo – an image with the sole purpose of recording a particular event or point in time. The second nature of a photo carries a ‘deeper meaning,’ which has the ability to change the observer’s mood and cause a reaction. But what distinguishes these two varieties? There are a

However as the authors stressed, probably more significant than the change in how images are produced, distributed and used, are the ideas to which the changes are giving rise and how digital imaging is challenging and changing traditional ways of seeing and thinking. It seems that our traditional belief that ‘the camera never lies’ has been brought into question. It also appears important to consider who

Most microscopes, including those in schools and laboratories today, are optical microscopes. They use glass lenses to enlarge, or magnify, an image. An optical microscope cannot produce an image of an object smaller than the length of the light wave in use. To see anything smaller than 2,000 angstroms (about 1/250,000 of an inch) a wave of shorter length would

     Industrialization is characterized by the increased role of technology as an integral factor of production. As industrialization and science further blend together, the economy becomes increasingly large and complex, making bureaucratic organizations more and more of a necessary function to the advancement of

“The prefix ‘nano’ stems from the ancient Greek word for ‘dwarf’. In science, it means one billionth (10 to the minus 9) of something, thus a nanometer (nm) is one billionth of a meter, or 0.000000001 meters. A nanometer is about three to five atoms wide, or some 40,000 times smaller than the thickness of human hair. A virus is typically 100 nm in size.” (Paddock) “The ability to manipulate structures and properties at the nanoscale in medicine is like having a sub-microscopic lab bench on which you can handle cell components, viruses or pieces of DNA, using a range of tiny tools, robots and tubes.” (Paddock) There is one type of microscope in the world that has the ability to see things at the nano scale. That microscope is a scanning tunneling microscope. It has the ability to zoom in on an object by 1,000,000 times as the average high school and college microscope only reaches 100(Nano.gov).
