Photography & Digital Imaging

Most serious photographers are concerned about copyright issues, and this isn’t just about protecting income. It’s also about having control about where your photographs appear and also this attitude in society that if it’s posted on facebook, or any other image sharing sites, then it’s available for anyone to make use of without even asking if it’s ok.

Personally I’m always pleased if someone likes one of my images enough to want to share them and I don’t mind people doing that as long as they ask my permission; it is for purely personal use; and they pop a credit to me or my website along with the image. Use for advertising or product promotion is something entirely different and I need paying for that.

So it was with interest I read with fascination this story about the

Copyright Threat reported in Amateur Photographer.

First thing that struck me was that this wasn’t the first time I’d seen a black and white photograph with one object coloured red.

…and yes it is one that I took and digitally manipulated, but it is a red object against a black and white background, with an interesting building behind it and a featureless sky, and a river. Am I too violating their copyright? Unfortunately their image (which I’d never seen before reading the article) pre-dates mine. But if I’d visited Shrewsbury in 2004 and gone through the same process four years earlier would I have a case against them? And I’ve seen this done on tv loads of times with a coloured object or actor against a b&w world.

But the truth is that there is an iconic red on black and white image in public consciousness and that arose from the film Schindler’s List. It looks great, and when things look great image makers first want to reproduce it and then improve on it and add their own personality to it. I remember reading something about font design several years ago and it was a statement to the effect that everything is built upon what has gone before. Rarely are ideas totally fresh – simply because our brains just register everything, most of the time without us even realising it. The wheel didn’t just appear fully formed with an axle – perhaps someone first spotted a fallen log rolling down a hill and then pondered upon that for a while.

If we go down the road of thinking that everything we think of is ours and was given to us in total isolation to anyone else’s input then creativity is dead. Just imagine if no one can any longer put a single coloured object against a b&w background – because that’s where this is leading. It’s a powerful visual concept and makes images stand out.

I thought photographic copyright was designed to protect photographers from unregulated use of their images. But this has shifted the playing field into the area of patents. It has the potential to set a dangerous precedent.

And yes I know that in this particular case there is another factor: that of Temple Island Collections actually offering this image to the people who then went out and copied it to apparently avoid paying Temple Island Collections their rightful dues. This, in my opinion, is an unworthy action. But unfortunately people steal ideas all the time. Most of us just shrug and get on with our lives – a little older and a little wiser.

By the way, for obvious reasons I haven’t downloaded the image of the red bus against the b&w Houses of Parliament even though I would have given credit for it. I hope AP got permission to reproduce it. So be sure to click on the link at the top of the article to see what all the fuss is about.

Do you know something about wireless spy cameras? According to the name we can say that this is a kind of camera that is used by a lot of people, but not for their original purpose. Usually this kind of cameras is used if an individual desires to spy on someone, catch a criminal or something like that. Despite its small size this item is very helpful and is used by a lot of individuals. It is incorrect to say that this type of cameras is new to the society. A lot of people consume them for any aim they require and know well all peculiar features of these cameras. Spy cameras are commonly accessible to you in two kinds. You can choose either wired or wireless one, but it depends on the aim it will serve.

In the majority of situations people choose wireless spy cameras as they are generally more comfortable and easy in use if comparing them with the wired ones. There are two main components that wireless spy cameras contain and they are named transmitter and receiver. These two constituents are inevitable for wireless cameras because they are the main parts that make these cameras functioning in a correct manner. It is very convenient that wireless spy cameras possess their innate memory as this allows you to store the data you require. When you make a picture, the transmitter of this camera sends the signals to the tank and the receiver in its turn treats the picture in a way you can realize. As it is a wireless camera there are some restrictions as for the distance you are allowed to transmit. There are different cameras; those ones that are permitted to deliver the signal to about several kilometers or some miles.

Nowadays you can see a lot of individuals using wireless spy cameras, but generally they are not devices that should be consumed by everybody. Earlier the professionals claimed that spy cameras were created and used only by the specialized services and authorities. In most of the cases these cameras were consumed by the military services so that to provide the soldiers with opportunity to beat their enemies. With the help of these items soldiers had a possibility to know the plan of enemy actions and had a possibility to prepare their private plan of how to beat them. But, as the technology improves quickly, today there are thousands of individuals who consume this wireless spy device. A lot of people use this camera for their safety measures because the specialized security systems are much more expensive in comparison with hidden spy cameras. Certainly these cameras do not possess such features as the security systems, but they are the best variant to protect your home from risky actions of other individuals. As you see wireless spy cameras are stated as very helpful device that can be used for many aims.

Buying a camera does not have to be something very hard. If you take into account the proper things, then choosing the proper camera could be easy. When you want to buy a camera, you have to keep your eyes on such factors as the use controls, the amount of megapixels, the battery life, the zoom lens and the exposure control.

- Battery life

As a rule, people fail to take the battery life into consideration while looking for a camera. What these people forget is that they could run out of battery when they need it the most. Just because a camera is expensive, it does not mean that it has good battery life. Today there are a lot of cheap models that have a good battery life.

- Amount of megapixels

The number of megapixels determines the quality of pictures. In most cases, digital cameras will be between 2 and 8 megapixels in resolution.

- Zoom lens

What you certainly need is a camera with good optical zoom. As well, it is recommended to ignore the digital zoom because it uses software to enhance the photo and thus the end result is a photo with poor quality.

When it comes to buying a new digital camera a lot of people get confused because there are a lot of various cameras on the market these days. And because of this, a lot of people have no idea where to start.

In the end, a lot of people just buy a camera to take pictures. And thus even if there are a lot of different things you need to take into consideration before selecting a camera, there is no doubt that color trueness and image quality are the most important things to look for. And thus you have to spend some time to check out the images that are generated by different cameras before you make a final decision.

The very first thing that you have to take into account is the resolution. Keep in mind that the quality of the camera and its pictures are directly connected to the image resolution. Remember that the more megapixels there are, the better the resolution. If you are a newcomer to the photography, then you can look for low or mid-end megapixel camera, however if you are a professional, then you have to look for high megapixel one.

When you have several cameras in your mind, you have to determine how easy they are to operate. A heavy or large camera could be difficult to carry as well as could be difficult to hold still whole taking photos. As well, it is necessary to check that all the main buttons for operating the camera are easy to use and locate.

The other thing to consider is the storage capacity of a camera. If you are going to take a few photos at a time and have a constant access to your computer for downloading, then storage capacity is not the main concern for you. However, if you are planning to use a camera while traveling, then you will find you need a large memory card. And thus while shopping for a new camera you have to keep it in mind.

Before buying a digital camera, consider for what purpose you will use it. If you need to illustrate your page on the Internet, it will be enough the camera with low resolution. But if you’re going to make prints from obtained images, to receive high-quality photos, you will need a camera with high resolution. Four main factors have a crucial impact on your digital camera:

- Resolution
- Method of operation of CCD
- An optical device of the camera
- Software that “works” with the image.

Resolution is determined by the number of light-sensitive diodes on the surface of the CCD. For example, if the manual says that it has a resolution of 1600X1200 pixels, this means that the CCD has about 2 million diodes on its surface. Each of three different diodes on the surface of the matrix can write data about one of the primary colors. In order to obtain data about the color of each pixel, we need to know information about the illumination of at least three diodes. This reduces the actual number of pixels in a three-fold. Instead it the software is used that allows you to equate the number of pixels and the number of diodes.

Although the statement “the more pixels, the higher the resolution, the better the image” in the main is true, however, other factors have a significant impact on the quality of the “picture”. So it is very important the quality of the production of the CCDs. The more qualitative made the matrix, the less it will have broken diodes (the size of one diode is about 7.5 microns), which will directly affect the quality of photos.

Unfortunately, the quality of the CCD cannot be described by any numbers or categories, so only a careful comparison of different models guarantees the purchase of the best camera. Focus on the field, clarity of the visible image. If you are satisfied with the quality of the image, then test the camera under different lighting conditions. Ask also, if possible, to print the captured image; it will give you more information about the CCD.

The digital photo cannot be comparable to the analog photo (which uses slides or negatives). From a technological point of view it is rather closer to the video shooting, which receives an image at every moment of time.

Let’s take a look at how the analog camera operates.

In simple terms, the analog camera consists of the system of lens, aperture and shutter; the light, having focused in the objective-glass, passing through the diaphragm at a time until the shutter is open, falls on a photosensitive film. Under the influence of photochemical processes the image is “recorded” on film and in the future it can be restored by developing.

Although digital cameras look like as analog, they use different principles of operation. Both cameras have the system of lens, aperture and shutter, but recording methods differ radically. The digital camera stores images in digital format on the special media. Closer examination helps to understand the difference in working methods.

The heart of a digital camera is CCD (charge coupled device) hidden behind the diaphragm and consists of a photosensitive semiconductor elements made from a variety of silicon diodes. When the light reaches the CCD, it charges each of the elements – pixels individually.

This charge in the future corresponds to an electric pulse, and so we get the data in digital form about illumination of each pixel. Since it is impossible to record all information about the whole image, but in future it is processed by software to recover lost data and recorded on magnetic media. Thus, the digital photography is a combination of CCD sensor, software and memory cards, replacing the film in the analog camera.

CCD matrix is not greater than the nail on the finger, and contains several millions of light-sensitive diodes, located on the surface of the matrix in the form of columns. Since the matrix responds only to the brightness, the digital camera can produce only black and white. However, there is a way to capture all the colors of the image by using different color filters in the lens: red, green, blue, or a combination of colors that gives the most realistic picture.
