RAW images are also known as “digital negatives” and they are often preferred by professional photographers. When shooting in RAW mode, the camera captures an image which is free of all default filters and adjusting, thus delivering something as close as possible to what you see with your naked eye. Main advantages of using RAW over compressed formats such as JPEG include better image quality, the possibility to adjust brightness and correct over- or underexposure during post-processing, as well as getting better colors on print.
On the other hand, RAW images are larger in size, require more time for processing and might pose accessibility options since digital camera manufacturers use different extensions for RAW files. For example, Sony uses ARW, Canon uses CR2, Nikon uses NEF etc. reaConverter supports over 45 different RAW formats, which you can easily edit and convert to more popular formats.
