All cameras save images in JPEG or JPG format for portability reasons, as it can be processed and displayed properly in any device, whether we consider mobile phones, tablets, television sets, and in any software application. This versatility is highly important even if the image quality available from the camera may be better than what the JPEG format offers. | All cameras save images in JPEG or JPG format for portability reasons, as it can be processed and displayed properly in any device, whether we consider mobile phones, tablets, television sets, and in any software application.

More advanced cameras and devices catering to professionals may list RAW formats as well, since it is a less processed image format that can extract more quality out of the initial shots. For most intents and purposes, RAW image editing and processing is much more difficult and the RAW format is specific to each camera, requiring dedicated support in image editing applications as other abilities to display such images is not available. Note that any processed RAW image will probably end in JPEG format anyway, as it is used on the internet or in other situations. However, having a good initial format or using it in subsequent edits makes | More advanced cameras and devices catering to professionals may list RAW formats as well, since it is a less processed image format that can extract more quality out of the initial shots.

However, having a good initial format or using it in subsequent edits makes PNGs and other loss-less formats the preferred choice that also offers versatility. Few cameras support PNG format savings, although some smartphone apps can be able to save in the PNG format. | ||
Video recording capabilities expose other important details about the camera sensor. Processing video on the fly is very difficult so the camera sensor image capabilities are much more readily exposed here. A camera that advertises a very high picture resolution in MP or megapixels, but a very poor ability to record video than another similar one, hints at unrealistic still image capturing claims. A good camera should be able to record also videos at a 4k resolution with at least a 60Hz or FPS (frames per second) ability. Higher resolutions and frame-rates are an indication of good sensors and logic but resolutions as high as 8k are somewhat impractical for video footage production and editing at the moment due to massive processing and storage requirements. | Video recording capabilities expose other important details about the camera sensor.
