Photography’s History

The history of photography can be dated back to the 1800’s.  Photography got its name from the Greek words "photos" which means light and "graphein" meaning to draw. The first person to use this term was the scientist Sir John Herschel in the year 1839. Thus, photography means the method or process of registering images with the aid of light , related radiation, on a medium that is made of sensitive materials.

The first image

During one summer day in the year 1827, the Frenchman Joseph Nicephore Niepce was able to achieve the creation of the first image that was fixed by working on it for 8 hours. His compatriot, Louis Jacques Mande Daguerre on the other hand was able to lower exposure time to a period of less than 30 minutes as well as preventing the captured image from disappearing.

Daguerre and the daguerreotype

Daguerre was the first to invent the most practical process for developing pictures during their time. He was born to a place in close proximity to Paris, France. Before experimenting on photography, he was a professional painter of various scenes in operas. After many years of experimentation with light and its effects on images, Daguerre was able to develop a process to make pictures that were more efficient and effective. He sold the rights to the French government then wrote a book describing his invention. 

The pinhole camera

Ibn Al-Haytham, who lived in the middle ages, was a greatly known in the field of optics. The pinhole camera was invented by Al-Haytham with the resulting image viewed upside down. A European named Della Porta was able to re-invent the pinhole camera, this enabled him to publish information regarding the pinhole camera.

The flashbulb

An Austrian named Paul Vierkotter is credited to be the first person to invent the flashbulb. He used a wire coated with magnesium which was placed in a glass globe that was vacuum sealed. This was later replaced with an aluminum foil inside an enclosure filled with oxygen.  The flashbulb became commercially available in the year 1930. It was patented by a German national, Johannes Ostermeier. The flashbulbs were called "vacublitz". General Electric, a company engaging in suh ventures made their own version which was termed "Sashalite".

Instant photos

You can take instant pictures using a polaroid camera. This type of camera was created by Edwin Land. His work on photography enabled a new age in photography wherein pictures can be obtained instantly. The exposure time was no longer a factor.

These are some fast facts that wil help you understand more the history of photography. Having a clear idea of how photography started will help you with your passion for pictures.

Food Photography Tips for Newbies

Taking great pictures of different food dishes isn’t as easy as it appears to be in cook books and food advertisements. This is why food photography can be tricky and learning some tips here can help you in taking great shots. Things that need to be considered include the dish’s angle, composition, lighting, as well as problems that may arise. Here are some guides to help you improve the quality of your pictures.

Lighting

Consider the lighting in the kitchen or venue where you will shooting the dishes. It is a good idea to know this in advance so that you no longer have to make adjustments right there in the venue. Dark venues may be corrected by using a row of flourescent lighting which possesses diffusers. The drawback of this method is that the image will have a subdued shade of green. Depending on the camera that you have, it may have a setting that neutralizes the effects of flourescent lighting or a magenta filter may be used to compensate.

Stability of tripods

Since you are taking pictures of food, every shot is done at close range. Unlike shots taken at a distance, shots done in close up are sensitive to movement. Any sudden moves and the picture will be ruined. Focusing on the subject also becomes easier when using a tripod or even just a stack of magazines.

Food presentation

To get that professional look, cut the dish in geometric shapes. Proper arrangement of the food is also important so that you will be able to showcase the dish’s ingredients as well as its strengths. Garnishing the food that you will shoot will enhance its natural colors, making it more appealing to the eyes.    

Focusing on the subject

A rather dull photo will become vibrant and dynamic if care is taken when focusing and adjusting the field depth of the camera. If your camera doesn’t have manual focus, depressing the camera’s shutter button halfway to lock the focus at that specific depth. Recomposing the focus can be done by changing the position of the camera while the shutter button is still depressed halfway. Automatic cameras usually lack aperture or depth of field. Some purposely adjust the aperture such that the background becomes a blur to heighten the subject’s features while others prefer that a wider depth of field is used to capture the whole scene.

These are some of the things that you should know regarding food photography. Constant practice will help you produce better shots. Follow your instincts. Sometimes this allows you to take better shots.

Aerial Photography

Viewing photographs which are taken from a good, unique point of view is one of the most fascinating things in the world of photography. This is what we refer to as aerial photography.

Origins
Aerial photography is formally defined as photograph taking from an overhead viewpoint by using cameras that are mounted on an airborne tool such as a balloon, an aircraft, a kite, a skydiver and other similar tools. The art of aerial photography was first developed by Nadar, a French airman back in 1858. During the Second World War, aerial photography found a niche in military operations. Aerial photographs were used in spying and in the assessment of the battle ground. These photographs provided updated and realistic impressions of the topography and current situation in a certain area.

Uses of Aerial Photographs
There are many conceived and actual uses for pictures which are taken from above. Aerial photographs are actually used in the construction of topographic maps, in cartography, planning land use, archeology, production of movie films, espionage, environmental studies, commercial advertising and in media fields.

The use of technology has also crawled into the field of aerial photography. Advances in radio technology has allowed for the use of aircraft models which are controlled by radio  in the conduct of low-altitude photography. This is mainly used in advertising for the real estate business. This is because manned aircrafts are not allowed to fly low altitudes in populated locations. This task can be done by these radio-controlled aircraft models and they do the job very well.

Public Domain
Aerial photographs are considered public domain, because the pictures are taken from aerial views which are considered public places.

There are many ways to view aerial photographs on-line. One of the most popular ones is the Google Earth by Google. Google Earth provides satellite imagery as well as aerial photos of the planet. You can actually use the service to be able to search for different places in a certain area such as parks, restaurants, schools and hotels. It can also be used to be able to track down the best routes for reaching a certain location. You can also view the aerial photographs in different angles by tilting and rotating them.

These are some basic things about aerial photography. If you are interested in learning more about this topic, you can browse through some basic materials at the local library or use the Internet to get more information about it.

It’s Time to Buy A Digital Camera

About a week before my son was born, I bought a digital camera. I wanted to create a baby book for him that would include not only his first year milestones, but also photos to capture his physical growth over his first year of life. I wasn’t sure which camera would be best so I went to Best Buy and talked to a sales representative. He helped me sort through the features and select a digital camera that would be best for my project.

If you’re a technology freak, you’ve probably owned a digital camera for years. But for someone like me, making the switch from traditional photographs to a digital format involved a leap of faith. It’s not that I don’t appreciate technology, I just wondered how good the pictures would be from a digital camera when compared to my trusty 35mm. So I bought the camera, brought it home, and began snapping pictures..

One feature about a digital camera that I love is the ability to review the pictures before printing and saving them. You can take a series of photos and then choose the best one without worrying about wasting film. But the most important feature, the one I was most worried about, was the quality, and I have to say that I was very impressed with my camera’s ability to turn out even better pictures than the ones taken with my 35mm.

Digital cameras have come a long way over the last few years, and now you can buy one with so many features that, if you’re an amateur photographer like me, you’d never even use. That’s why it’s important to talk to a salesperson when you’re buying a digital camera for the first time, so that you can decide what features you need and which features you can surely live without. Since I would be mainly taking pictures of my family, I didn’t need a digital camera with a tremendous zoom feature. But because I would be taking photographs most every day for a year, I did need a digital camera with a good battery. These were just a couple of the features I talked about with the salesperson at Best Buy and he was able to direct me away from the high-end professional cameras to the more reasonable ones without all the special features. I ended up spending extra money to get a digital camera with a good battery, but it was worth it because I hardly ever ran out of juice during an important event.
