The camera has one small, slow chip and very little memory to do that interpolation. Your computer has a big, powerful processor and lots of memory, not to mention, no particular need to compromise their software routines to fit into a small amount of memory or trade quality for speed to avoid long delays after taking a picture. In short, your computer will do a vastly better job at interpolating the picture than your camera will, and to top that off you can choose different algorithms (often named after the mathematicians or programmers who created them, like Lanczos or Mitchell) and experiment with how well they work on a particular image. You can even save different versions of the file, including the original, which you can't if the camera is doing the work. There's nothing to be gained by compromising image quality, which is exactly what you're doing if you don't use the best filter you can get your hands on. The interpolated image even takes up more space on your camera's memory card, but it doesn't hold any more information than the original. Finally, as I mentioned above, it adds time between shots, as the camera has to grind away at reshaping your picture before you can take another one.

You can recreate the settings of a favorite shot or repeat a favorite effect, and higher-level information such as special lenses and light metering modes can be invaluable as you advance your knowledge of photography. You can even share this information with friends or colleagues to help duplicate tricky shots, or create a database or spreadsheet of the effects of specific settings to help you recreate effects or types of shots under different conditions. An example would be keeping track of how white balance changes affect the appearance of particular colors. Instead of making notes of what changes you made and what order photos were taken in (particularly when the string of photos were all taken of the same scene), you can skip the notes and compare the settings in the EXIF data instead. Then, when you work on your log, you can copy setting information over and just make a note about which settings worked best.

What is it that is actually capturing the image? Where film cameras have a roll of film exposed behind the aperture, digital cameras have a sensor. Most digital cameras use an array of photo sensors under a filter matrix which results in the sensors each recording red (8-12 bit), green (8-12 bit) or blue (8-12 bit) light intensities. These separate sensors or channels create what is often referred to as the Bayer matrix pattern where every other sensor records green with the alternating cells recording in red or blue. Each pixel in a conventional sensor only captures one color. This data is typically 10 or 12 bits per pixel, with 12 bits per pixel currently being most common. Most cameras now provide the option to instantaneously store the captured material in a RAW file while alternatively the camera's processor can weave the RAW data using all three color channels to provide an instant 24 bit full-color JPEG or TIFF display image. RAW is not an abbreviation but literally means "raw" or "unprocessed". A RAW data file contains the original image information as it comes off the sensor before in-camera processing so you have a variety of choices in processing the data on your PC using one of many editing software programs available.

Higher temperatures and long exposures may increase the occurrence of hot pixels. Fixed pattern noise is unique where it often shows similar distributions of hot pixels even if taken under the same ISO speed, temperature and length of exposure. Fixed pattern while the most objectionable visually, is the easiest of the three to remove because it is a repeated pattern. Once the internal electronics of a camera knows the pattern, it can subtract the noise away to reveal the true image. Banding noise is associated with the camera model and related characteristics. It is most visible at high ISO speeds and in shadows. When brightening an image, banding noise may become noticeable when using white balances. It is not always the number of pixels that reduces noise, but actually the greater the area of a pixel in a camera which allows a greater amount of light into the pixel causing the sensor to produce a stronger signal. Cameras with physically larger pixels generally appear less noisy since the signal is larger relative to the noise.

This editor offers many of the common features any photo editor may need. There is a freeware photo editor called Image Forge Image Forge lets you paint and edit many of your photographic images. You can create some special effects and make one of a kind prints with Image Forge! With Image Forge, you can easily correct any problems that you find with your digital photographs. Whether you want to touch up a person's face, erase a tree or add stunning color, you can do it with this software. If you want to instantly find and edit any and all of the pictures on your personal computer, there is no better tool to use than a freeware called Picasa! This program works to help you organize and sort through all of your digital pictures. You can make stunning photo collages and albums, as well as edit any problems you may have with any given picture. Picasa also allows you to create a photo "album" that you can send to a website to share pictures with your friends and family. If you take pictures, especially digital, then you know how important it is to be able to edit. Whether you are a professional photographer or it is a hobby, you will want your pictures to be the best that they can be, right? Well, most photographers, novice and beginners alike, are not perfect. Therefore, they will not produce a perfect picture. The vast majority of the pictures taken will need to touched up in one way or another.

For best results using fill flash, try to have your subject in shade with lit areas behind it. The fill flash takes care of the shade, and helps balance the light level so the subject and the background are clear and proportionately bright. If your camera has a "slow synchronized flash" feature, this can be used to combine foreground and background elements in a way not otherwise possible (because of the short reach of small, built-in flashes). With the use of a tripod and relatively still subjects, good quality shots can be taken in otherwise difficult conditions, such as night shots or even shots on a moving platform. Longer shutter delays can produce blur effects similar to the "moving traffic" effects often seen in advertising, and with a little patient experimentation you can produce shots with a mid-range digital camera that rival expensive commercial art.

Memory Sticks are used only in Sony products, and Sony is serious about keeping the technology in use. Unfortunately it seems like no one else is. They're available up to 4 Gigabytes in capacity, have good speed, but if you're using a Memory stick, it's probably because you're using a Sony camera and you don't have a choice. The newest common storage media are xD-Picture cards. Developed by Olympus and Fuji as a replacement for the older Smart Media cards, xD cards are compact and durable, with a heftier shell than older designs. They are stable in the market and likely to be around for a while, but they are gaining neither market share nor size rapidly - currently the largest xD cards are 1 Gigabyte. This is probably because only Olympus and Fuji now use this standard. Wide and wafer-thin, Smart Media cards define "legacy technology." Available only as large as 128 Megabytes, this is one technology I would have expected to have been "voted off the island" by now. Alas, they were used in tens if not hundreds of millions of cameras and smart phones, so they are still being made and will be available for some time. You won't find them in any new cameras, however.
