Image File Formats: JPEG vs RAW

Submitted by webmaster on Mon, 05/11/2009

While most PowerShot cameras can only store digital images with the JPEG format (Joint Photographic Experts Group), the PowerShot G10 and SX1 IS have an ability to capture images with RAW file format.

The JPEG file is more compressed than the RAW file so some details are lost. However, the size of JPEG files is much smaller than the RAW. As a result, JPEG files require less space and can be transferred more quickly.

The RAW format is the way to store more details of images. If you try to capture high contrast pics, using the RAW format will yield the best result. The downside of RAW files is that they require more spaces so you will run out of memory so quickly. Another disadvantage of the RAW is they are not standardized or documented, and differ among camera manufacturer. For example, Canon's RAW format is not alike other vendors' RAW formats. If an application is able to open the RAW format from Canon, it doesn't mean that it can open RAW files from Nikon cameras. Moreover, some RAW formats have been effectively orphaned already.
