An image file format that uses ‘lossless’ compression but produces much larger files than JPEGs. It’s sometimes offered as a file format on more advanced cameras but it’s more useful later on as an image file format for image editing and manipulation on a computer.
Cameras with the ability to shoot RAW files will almost always offer a RAW+JPEG option too. Here, the camera shoots a single image but saves two versions – the RAW file and a JPEG processed and saved with the current camera settings. The JPEG is useful because you can share it with other people straight away and it also offers a useful benchmark when you’re processing the RAW file later.
MP4 is a video file format used by many digital cameras. It’s simple to work with because it produces a single file containing both the video and audio and it’s simple to drag from one device to another. It’s often provided as a similar alternative to AVCHD on Sony and Panasonic cameras.
Most digital photos are shot as JPEG images. This is a universal image file format that uses sophisticated compression to keep the files small and manageable. JPEGs are created by processing the RAW data captured by the camera. Some cameras let you save these RAW files instead. The files are larger and you need to process them later on a computer, but they offer the potential for better quality.
This is a standardised, universal file format for digital photos that can be displayed by practically any device without any kind of conversion. It uses powerful compression to reduce the file size of digital photos so that you can get more on to a memory card or a hard disk, and they’re quicker to transfer. There can be some loss of quality (often invisible to the naked eye), so for ultimate quality many photographers shoot photos in their camera’s RAW format instead. It’s only more advanced cameras that offer this RAW option, and it produces much larger files which you will need to process yourself later on.
