Looking into price index in a little more detail reveals more facts! SLR (single-lens reflex) digital cameras have attained quite a price shedding with invention and market release of digital cameras like Canon's EOS Digital Rebel, an SLR priced below $1000, perhaps very first of its kind. Even with certain add on into digital camera that even add to price a bit more, still Rebel cost remains about $600 below its flanking competitors. However comvention has it that these standard digital cameras cost around $2500 to $4,000.

In an effort to find out reasons behind such soaring high prices, research reveals that digital camera sensors are, for all intents and purposes, computer chips. The bigger computer chip, more likely it is for errors. The reason remains that a single blemish in silicon wafer may reduce to rubble an entire chip. Thus random flaw increases with size of wafer. This is exact reason why costly chips like Intel Pentiums processors are basically not bigger than 20mm square and can be also manufactured in greater volumes. Yet with reduction in size prices soar up and this proves high costs of digital cameras.

Thus it becomes clear from this discussion that a predetermined mind set is required when approaching for purchasing a device like digital camera. This discussion provides an overview of price ranges of good digital cameras, but a person must identify his or her own needs and preferences and have an open mind but with some notion of what a good but should be, and cost of digital camera would be a guaranteed perfection!

The next digital camera file format is TIFF (Tagged Image File Format). This file format has greater advantage that it does not lose any image file information during compression process and moreover as a consequence it does take up a lot of space from a memory card in comparison to a JPEG image. Due to this detailed storage it also takes additional time to retrieve information to card. Basically TIFF compression reduces images to about one-third their original size as per convention.

Coming to next digital camera file format. It is defined as RAW file! It is also sometimes referred to as an appropriate digital negative. Most advanced digital cameras allow or permit ability to shoot RAW in professional standards. The interesting portion is that in a RAW image no alterations are made by camera (such as sharpening or white balance). And this gives entire control to photographer when he or she processes an image later. However this RAW file format is not used extensive due to fact that most image editors cannot open it and computer-processing time is also more. However fact still remains that a RAW image has a smaller file size than a TIFF.

With all these discussions regarding different digital camera file formats, it is clear that three most widely accepted file formats have their own advantages and disadvantages, yet they are unique in some way or other that makes them special in their own manner. The knowledge about these digital camera file formats of storage not only yields greater understanding of camera; it also opens eyes towards fantastic results of technological advancements in our daily lives.
