Digital Photography Tips and Tricks

The main problem that affects digital photography is camera shake. Many photos will be ruined due to camera shake. When you are taking a photograph using the point and shoot camera the shutter remains open for a longer period. This shutter is open for such longer period to ensure that you get a good exposure. The time the shutter remains open depends on the lighting conditions. When you move your camera during this time, the photo is blurred. The camera shake problem occurs due to camera movement when the shutter speed is slow. The movement of camera will be shown as motion lines and ghost images.

Low lighting conditions and slow shutter speeds are the reasons behind camera shake. You can solve this problem using faster shutter speeds. This is important while using hand held point and shoot camera. The one over focal length will help you to solve this problem. This rule will help you to figure out the required shutter speed. A 35mm SLR camera with a lens having a wide angle 20mm can use a shutter speed of 1/15. You can use the rule to calculate the shutter speed depending on the focal length and the type of camera used.

You can sole the problem of camera shake using camera accessories like tripod and camera flash. Camera shake occurs do to camera movement when the frame is exposed. You can fix your camera on a tripod to solve this problem. Tripod will help you to stabilize your camera for longer period. This will allow safer shutter speeds for longer period. The lighting conditions are another factor that affects shutter speed. The shutter speed will be slower when the lighting conditions are low. You can use a flash to improve the lighting conditions. The subject has to be closer to the photographer for this method to be effective.

DIGITAL CAMERA FORMATS

Digital cameras are technology at its best. By preserving your pictures on a digital format instead of regular film, you not only save a lot of money in film processing, but have almost unlimited room to store them on your computer’s hard drive, or compact discs. The only drawback to digital cameras is the various formats these photos can be stored in and finding the right devices that work together. Typically, digital photos are formated in either JPEG, TIFF, and/or RAW.

JPEG Images Are Universally Standard For Websites and Email

Most digital cameras come with the JPEG (pronounced Jay-Peg) photo format. For those who are interested in keeping their images small, compact, and for use in email and websites, JPEG is the perfect option. Starter digital cameras, such as the Point and Shoot type, are often universally JPEG for ease of use.

JPEG images are termed as “lossy”. This means that because of the compact nature of the file, a JPEG file will lose some of it’s quality when enlarged. JPEG will produce quality pictures for smaller photo sizes, but when enlarged the compression of the pixels can’t return to a decompressed state. The pixel arrangement is unrecoverable. A popular feature with JPEG featured digital cameras is that there are 3 levels of compression to choose from for different qualities.

Of course, it should be noted that the format of the photo isn’t the only criteria for good quality photos. Light, location, environment, and quality of the camera are major factors to take into consideration when taking digital photos.

JPEG is a great choice if you are using a smaller SD Card of 1 to 4 gigabytes. It is an easy format to use with most photo software, and are good when taking a lot of pictures. However, if you are going to go for professional quality, or working with pictures sequences you might want to take a look at the other two formats; TIFF and RAW.

TIFF Digital Format Is Slowly Losing Ground To New DSLR Cameras

A very old digital format for pictures is the TIFF (Tagged Image File Format), which is slowly losing favor to the other two formats mentioned. Most of the newer DSLR digital cameras are phasing out the TIFF for easier to use JPEG.

That should not be a frown upon the quality of picture that TIFF can produce. While the newer cameras are coming in either RAW or JPEG, or both, TIFF should not be underestimated. Being a little larger than a JPEG format, a TIFF file is one that can be compressed, and enlarged, without any loss of quality. The file is “lossless”, or no information transposed onto the file from the picture taking is loss due to compression.

Although digital cameras are phasing out the TIFF format, it is wildly popular in archiving documents and files. Because of the quality of the file and the flexibility of it, it is the most widely supported format across most platforms. This includes Mac, Windows, and Unix. TIFF also stores data in all forms up to 48 bits of encryption and most color spaces, RGB, CMYK, YCbCr, etc.

RAW Is Not Universal But Highly Workable

RAW is the unprocessed, uncompressed raw data captured by the camera’s image sensor before any of the in-camera processing has been completed. With this in mind, RAW format is the equivalent to the negative of a regular film camera.

The RAW image format allows the photographer to make a wide range of changes while maintaining the quality of the original picture. Since no processing, or compression, has been done to the image, it is of high quality but also very large. The drawback to a RAW file is that is requires either camera specific software, or highly specialized third party software to manipulate the image file.

Some high end cameras, such as Nikon and Canon store their images in RAW or TIFF files so the user has a better quality image. Mass produced Point and Shoot cameras, that cater to the recreational photographer, use predominately JPEG for their file formats.
