Kodak Digital Cameras - The Giant Comes To Digital
George Eastman, founder of Kodak is world renowned today. Digital cameras or cinematography, Kodak has excelled in all fields. In this article, we will view the rich history of Kodak's rise. It all started in the year 1879 for Kodak, when George Eastman obtained an American patent for his plate coating machine and started manufacturing dry plates. In 1888, Eastman introduced the concept of manufacturing films in rolls and thus made it possible for all to possess a camera. This Kodak camera came with film for 100 exposures at just $25. After the pictures had been clicked, the camera could be returned and the film would be developed and replaced just for $10. This level of innovation started a period of no-return for Kodak. Eastman's aim was that "you press the button, we do the rest". He has achieved this through constant innovation by making the camera simpler to use and making photography an enjoyable experience today. In movie making technology, since the Academy Awards have started, all Oscar "Best Movies' have been shot on Kodak film. In fact, Kodak itself has won eight Academy Awards for scientific and technical excellence in cinema. Kodak has also introduced the concept of 'infoimaging'. As the name suggests, it means communicating through pictures. In the late 80's, Kodak started to make great advancements in digital technology. It developed the concept of Organic Light Emitting Diode (OLED) displays which depicts information with the use of self-illuminated pixels and does not require any back lights for support. The OLED also provides clearer images, sharper contrasts, and lower energy consumptions as compared to LCD display units. In fact, it is Kodak who is considered to be the inventor of the basic technology utilized in a digital camera i.e. the pixel technology. In the year 1990, Kodak introduced the Photo CD. This CD enabled people to store photographic images onto a CD and then view them on a computer. As a result, it became more practical for people to use a digital camera. Then, in the late 90s, several companies including Kodak launched digital cameras which could be used at home. Kodak also tied up with Microsoft in the year 2001 so that digital camera manufacturers could use the Picture Transfer Protocol (PTP) through Windows. This would enable people to easily view and share their pictures through the Internet under an Windows operating system. Today, as technology advances, Kodak has introduced several hi-tech digital cameras such as the Kodak Professional DCS Pro SLR/c. These cameras are capable of storing 13.89 million pixels, which makes them the digital camera with the highest resolution available in the market today. The latest digital cameras by Kodak today are as follows: Easyshare Point-and-Shoot Series: The C and CX series are simple and low cost cameras. Easyshare High Zoom Series: The Z and DX series have extensive zoom and provide control to the photographer. Easyshare Pocket Series: Small, compact cameras for travelers. One time use Digital Cameras: Single use digital cameras. Kevin Rockwell worked as a network TV cameraman for 20 years shooting news and sports. Now a devoted fan of digital photography and video he works to gather information, tips and news for digital camera users. Oh and he loves to shoot pictures of his kids playing sports. http://great-digital-cameras.com/gdcj.html

Basics of Photography Understanding light is one of the very basic principles of learning to be a photographer. When you have a group of people in front of you with smiling faces ready for you to say 'cheese' or if you are taking a shot of a scenic area, the most important consideration is the light factor. Light controls the type of exposure and therefore the quality of the photo is dependent on the quality of the light on your subject and the amount of light that impacts on the film or digital sensor when you click. Controlling the amount of light is a good pre-occupation in the mind of a photographer keen to get a good shot. It should be one of the key considerations. The word 'exposure' is a very important word in the lexicon of both amateur and professional photographers and is based on the understanding of light in creating good photographs. --If there is too much light, the photo will look overly bright and over exposed. --A happy group of people will not look as vibrant if there was inadequate light when you took the picture. --Bright sunlight can create shadows under the eyes. --Poor lighting may not bring out the colors in the scene to maximum effect There are a few basics that you can apply to circumvent poor picture quality due to unfavorable light conditions: --Change the position from which you take the shot --Change the light if clicking indoors --Use the flash The use of the flash can be a boon when you operate in different light conditions. If you have an overcast sky, the flash in your camera will serve the purpose of letting some light into the image that you are trying to capture and brightening it up. The flash also works to your advantage when your subject is not too close but slightly away from you. But you have to check the 'flash range' of your camera in your manual. The flash works best when your subject is within a recommended range that is usually at least 4 ft and generally not more than 10 ft. Most simple cameras have an automatic flash. Slightly better models will have settings for fill-flash. The concept of fill flash revolves around filling light in areas of a picture that may turn out dark or shadowed. Fill-flash has the ability to balance the amount of light on different parts of a subject to ensure that the exposure is adequately bright. For instance, a portion of a person's face may appear shadowed and the fill-flash setting can help iron out this problem. The angle of light is another important consideration. You have to pay attention to the direction from which light falls on your subject and there are several approaches in manipulating the angle of light to improve the visual appeal of a picture. Sideways lighting: Light from the side is used to creates depth in the picture and is considered one of the best ways to use light if you are taking a portrait photograph. Light from the top: This is a method used to brighten up most of the scene but does not work as well when you take a photograph of a person. It tends to create shadows on the lower half of the face when the lighting is high. Light from behind your subject: This strategy is sometimes used by photographers to amplify the impact of the picture. It can create a halo like effect; it can add artistic shadows and can also create a striking contrast between the subject and the background if used effectively. When you use a 'back light' it is recommended that the fill-flash settings on your camera are also adjusted in order to avoid shadows in your photograph. The second issue in photography is the aesthetics of the picture. Aesthetics is the creativity and attention to detail that you bring to your photograph. It is the most interesting part of photography since it is almost like a visual equivalent of composing a poem or writing a story. Aesthetics requires the use of visual skills to compose and deliver a pleasing, eye-catching and captivating image. It is a type of vision that you have for your photograph in terms of look and appeal. Aesthetics requires a good eye for detail. The following factors have to borne in mind in creating an aesthetically appealing photograph: Background --Periphery --Distance from subject --Changing the direction of your camera based on picture dimensions --Objects impinging on the picture --Avoiding too many elements Each of these factors that go into aesthetics are described and explained below- -->Background The background in a photograph requires much consideration. It influences the manner in which your subject is portrayed in the photograph. Depending on your choice of background, your subject will be shown to effect or may be overshadowed. The background also makes the difference between a boring and an interesting photograph. The colors, the type of background and the context add to the vibrancy of the photo. -->Perphery A common problem among beginners in photography is not paying attention to whether the image is being captured fully. When you view your subject through the viewfinder, you may think you have clicked a person from head to shoulder or from head to toe in a full shot. But when the actual photograph is processed, the top of your subject's head or part of the hair may be missing! Or, if you did not center your subject when you composed the shot through your viewfinder, a part of the shoulder or hand may be lost into the edges of the photo. You need to concentrate when you view your subject through your camera before you click, in order to get the picture exactly the way you want it. -->Distance from Subject The distance from a subject is another critical aspect in getting a good picture. You want to see facial expression, not a mass of faces when you take a photograph. To do this, you have to be at a suitable close distance from your subject. On the other hand, when you click pictures of a campus, the distance that you click from can give you a wide view and take in a lot more of the scene. To take close up pictures of flowers or crystal or any decorative item, you have to move into close range and use suitable lenses to achieve the right magnification. -->Changing the Direction of Your Camera Based on the Picture Many a time you may not be able to capture the subject in it's entirety in the conventional horizontal position in which the camera is usually held. You can easily change the direction. Hold the camera vertically and then view your subject. You will be able to capture more of a longish subject like a tall monument, a full-length picture of a child, and so on. -->Objects Impinging on the Picture At times there are certain objects in a scene that seem to almost invade into the picture. For instance, if you take a picture of a group of your friends on a street, chances are that a street sign may gain prominence in the photograph unbidden and may seem to sprout out of the head of one of your friends in the photograph. Or the light fixtures in your living room may find a place in the picture and appear in the form an unseemly blob in your photo. And the tough part is, when you take the shot you may not be aware of this because the eye is focused on the people in the picture. -->Avoiding Too Many Elements A picture cluttered with too many objects may detract from the actual subject. For instance, a wide view of a room in which your subject is sitting may create a photo in which too many objects vie for attention. If the person in the picture is your main target then narrow down and concentrate mostly on clicking the subject. While a good background adds value to a picture, too much paraphernalia could take the attention away from the main subject. Your picture may be focused and the lighting may be good but there is so much going on in the picture that it becomes aesthetically lacking and maybe even a little jarring. Besides Light and Aesthetics, the third issue in photography basics refers to 'focusing' the picture. Getting the right focus is the difference between a blurred image and a sharp image. If you have an auto focus camera, the camera will do the job for you. This is available in most basic models. You can also achieve focus manually in other cameras using the mechanism to adjust the focus and to lock the focus on the subject before you click. To achieve the right focus, it is important to decide on the artistic elements of the final picture. There are areas of a scene that you may want sharper and clearer. For instance, when you photograph a famous monument, you may want the building as well as the blue sky against which it is silhouetted to be crystal clear. If you are photographing a camel in a desert, you might want the camel to be clear and a slightly hazy/blurred effect of the surrounding sand. If you are taking a shot of a room containing a priceless vase, when you look through your viewfinder, you want the finer details of the intricate patterns on the vase to be clearer than other objects in its vicinity. So, it's also a question of the portion or key part of your picture your focus is really on. This area that you identify for your focus is referred to as the 'depth of field'. You can lock the focus on the depth of field that you choose. You can control the focus and depth of field depending on your objectives for different shots. The basics of photography are better applied when you put into perspective the capabilities of the camera model that you use or plan to purchase. Simple point and shoot cameras require minimal knowledge in operating them. They are easy to use and have the bare minimum controls. The user has to just compose and aim the shot on the subject and presses the shutter button. 'Click' and the job is done. The camera handles its functions automatically. For those of you who want to work with a slightly more sophisticated camera, you have the option of a Single Lens Reflex camera popularly called the SLR system. This type of camera is available in both 35mm film format as well as digital format. Digital cameras have no film but the image is captured on an image sensor and stored in photo memory. Digital cameras in general provide superior picture quality. The internal system of the SLR camera is made up of angled prisms and mirrors that actually work like a lens when you click. But you have a few things to learn about this camera system before you can achieve better light exposure, sharpness and good focus. While it is imperative that you study the instruction manual of your SLR camera system thoroughly to understand the features and functioning, given here are some of the features and a brief explanation on how these features can help you in achieving the right exposure. -->Additional Lenses for Close Up Shots An additional feature in an SLR camera that makes it far superior to a simple 'point and shoot' camera is the ability to use add-on lenses. When you attempt to take a close up shot of objects in nature like a flower or a butterfly, you might want a very high level of clarity. You can add power to your camera by attaching an additional lens onto your camera lens for greater magnification of your subject. These supplementary lenses are available at reasonable prices in different powers like +2, +3 and so on. You can also look for a model with an optical zoom lens that gives you the flexibility of variable focal length and a range of lens options within a single zoom lens. -->Shutter Speed The shutter in your camera lets light in during a shot and keeps light out at other times. When the shutter opens for an exposure, light is allowed to impact on the film or image sensor. If you set a slow shutter speed, more light impacts on the sensor and affects the type of exposure. When you use a faster shutter speeds your picture is sharper and clearer. There is a maximum shutter speed that is available to you in your camera system. The shutter speed is set at a fraction of a second- for instance, 1/1000th of a second. It could also be 1/2000th or even the much-preferred higher speed of 1/4000th of a second that is available in certain models. Professional use models boast of even higher shutter speed of 1/6000th or 1/8000th of a second. If you want to freeze action such as in sports, you require fast shutter speeds. There are many more features that when used effectively can add value to the impact of your photographs. Most 35mm SLR cameras have a TTL viewfinder. TTL stands for 'through the lens' metering system. This device has the ability to measure (on a scale) the amount of light impacting the film. Using this device is the key to control the exposure and get the right amount of light in order to capture a proper image. You can also use a tripod with your SLR camera. A tripod is your answer to achieving the right exposure in a close up shot and in low light conditions. It holds the camera steady, helps in focusing and ensures a sharper picture even when shutter speed is slow. The guidelines discussed here on the basics of photography and the additional features of the SLR system, will not only get you started but also help you avoid the common mistakes that many budding photographers make. Study your manual thoroughly for insights and ideas. Learning photography requires patience and the ability to constantly experiment and teach yourself through a process of trial and error.

Digital Wedding Photography: Myth Vs. Reality 1. Myth: Digital photos are pixilated or fuzzy. Reality: most people that say that have never seen a photo produced by a professional grade digital camera. The quality of modern digital cameras is equal of greater than film cameras. Digital RAW Workflow for Beginners Having an efficient work flow is essential for photographers. In the days of film, many of the tasks in the film work flow were handled by the lab. Now, more and more photographers are switching to digital and have to handle many of these tasks themselves. The purpose of this document is to provide a basic digital work flow for working with RAW images that is camera and system independent. Most modern digital SLR cameras, and some point and shoot models, have the ability to record the RAW data from an exposure, allowing the photographer to process the images as they see fit. This can be a daunting task, especially for those who don't have a work flow in place to handle the images from the camera. The following steps will take you through the process of setting up your own RAW digital work flow. Work flow Step 1: Compose and Expose Your digital work flow begins before you ever sit down at your computer. One of the best things you can do to make your work flow more efficient is to get as much of your image perfect in the camera as possible. Many digital photographers have fallen into the "I can fix it on the computer" trap. This costs you time and money. The more time you spend "fixing" a photo after you've tripped the shutter, the less time you are spending with clients. Here are a few tips to help reduce your workload from the time you make your exposure: Set your white-balance to match your scene. If you get the proper white-balance in the camera, you won't have to adjust it later on the computer. See your camera documentation for how to set a custom white-balance. Remember to set your white balance whenever you change lenses, or the quality of light. If you change modifiers, or lenses, change your white-balance as well. Expose for the highlights. Since digital acts similar to slide film, its easy to accidentally blow your highlights. By exposing for the hot parts of the image, you'll save yourself some time in the long run. Scan your frame. Get in the habit of doing a top-to-bottom scan of your frame before you trip the shutter. This will help you avoid stray hairs, lights in your frame, reflectors being visible, and anything that you might have to clone out of the image later. Work flow Step 2: Importing and Backing Up Your Images There are many ways to get your images from your camera to your computer. Some people use a card reader that will read the images off the memory card from the camera. Others connect the camera directly to the computer and import the images directly. No matter how you get the images to the computer, your first step is to setup an organizational structure for the images and create a backup copy of the RAW files for safety. First, create a folder to store your image files. In our studio, we use the folder name to organize our images. For instance, let's say we are importing images from a portrait session with Jane Doe that took place on January 1st, 2005. Our folder name for this session would be P_2005_DoeJane_0101. If we also did a portrait session with John Doe on the same date, our folder would be named P_2005_DoeJohn_0101. This allows us to keep our images organized in a way that we are familiar with. Use whatever folder structure you like, as long as it helps you keep things organized. Next, we will create the folders under our P_2005_DoeJane_0101 folder that we will use during the course of processing the images. We create the following folders: RAW, WORK, and JPEG. The final file structure looks like this: -+P_2005_DoeJane_0101 -|-RAW -|-WORK -|-JPEG The RAW folder holds our RAW image files, the WORK directory holds the processed TIFF files where we will do all of our editing, and the JPEG folder holds the completed files, ready to be uploaded to the lab. Copy the images from your camera to the RAW folder using whichever method you prefer. As soon as this initial copy is complete, make a backup copy of these images. Some photographers backup to writable CD-ROM or DVD discs. Other photographers backup to a separate backup hard drive. No matter what method you choose for your backups, they are CRITICAL. Make sure you can recover your images if something should happen to your memory card. Work flow Step 3: Verify Your Backup Your backup copy of the RAW images files is important. Take a moment to verify that you can read the images you copied to your backup medium. Once you have verified your backup medium, you may proceed with the work flow. Work flow Step 4: Culling the Herd Converting the images you never want the client to see wastes time and money. Use your preferred image browser to go through the RAW images and delete any that you know you won't use. Don't worry about deleting the wrong file, that is why we made a backup. If you delete a file you wanted, just bring it back from your backup. Once you have selected your "keepers" from the RAW images, it is time to move on to the next step. Work flow Step 5: File Conversion Most cameras come with software specifically designed to convert the RAW image data from its native format into TIFF files, JPEG files, or some other format that is compatible with the popular image editing software. At our studio, we convert the RAW images into 16-bit TIFF files, because we like to have the maximum amount of data available for editing and processing. Your needs may vary. There are many articles on the Internet that deal with the different file formats and the pros and cons of each. For the purpose of this tutorial, we are going to assume that the files are being converted to 16-bit TIFF files. We now open the software that came with our camera and set it to convert our RAW image data to 16-bit TIFF files, and save them in the TIFF folder we created in Work flow Step 2. This step can be time consuming, so we often go out to eat while the images from a session are converting. Once the conversion is finished, you will have a folder of 16-bit TIFF files to do editing and retouching on. We use TIFF at our studio because it is a loss less format. That is, we can save the file as many times as we like without degrading the image quality. JPEG is a lossy format, every time you save a JPEG file, you lose a little more data to compression. Work flow Step 6: Editing and Retouching This step of our work flow is where the real work is done. You will open each TIFF file in the image editor of your choice and make sure your colors and exposure are correct, the crop is the way you want it, and the image is ready for printing. At this point you will make any edits to the image, such as changing the crop, converting it to black and white, or doing any needed retouching. If you use the TIFF file format, you can save as many times as you need to during this process without having to worry about losing image quality. Once editing and retouching is done, save your work file and move on to the next step. Work flow Step 7: Saving the Production File One of the cons to working with 16-bit TIFF files is that they take up an incredible amount of disk space. Once we have reviewed the images with the client and ensured that no further edits/retouching need to be made, we convert the TIFF file to a JPEG production file for archive purposes and sending to the lab. Open the TIFF file in your preferred image editor and save your file as a Baseline Level 10 JPEG in the JPEG folder we created earlier. Why not save as a Level 12 JPEG, you might ask. When printing your image, there is no discernible difference between a level 10 JPEG and a level 12 JPEG. Try it for yourself and see. Once your files are saved as JPEGs, move on the the next step. Work flow Step 8: Backup Your Production Files This is a good time to make a backup (either to CD/DVD, or to another hard disk) of your JPEG production files. This ensures that you have a copy of all your hard work and if something should happen to the original files, you know you have a good backup. Work flow Step 9: Cleaning Up the RAW and Work Files Once we know we have a good backup of our production JPEGs, we delete the entire WORK folder and the entire RAW. This frees up the large amount of space that TIFF files require and leaves us with a manageable set of files from the job. However, we have already made backup copies of the RAW files and the JPEG files, so if we ever need to re-edit an image, we have the materials to do so. Work flow Step 10: Final Touches At this point our production JPEG images are ready to print or send to the lab. Make any final adjustments to the image size and print or upload your images. Final Thoughts With an efficient digital work flow, handling large amounts of digital images is easy and relatively stress free. I hope this tutorial has given you some ideas on how to best setup your own RAW digital work flow. Using a Camcorder to Record Family Events Quickly and Easily Let's start there (but not spend too much time on it because you are probably already checked out on their use): Is your Digital Camera Compatible With Your Computer? So you recently bought a digital camera or perhaps your thinking about it. And perhaps you may be wondering how many pictures will your computer hold? First you need to answer a few questions to come to an accurate conclusion. First, how big is your hard drive and how much free space does it currently have? You can find the answer to that question by first left-clicking on "My Computer:" Right-click on "C drive." A menu should appear. Left-click on "Properties." A pie chart should be displayed that will show you the size of the hard drive and how much of the disk drive is free. Your next step is too know how many mega pixels does your camera have? A pixel is a light sensing cell on the image pickup device. Help!
