Digital cameras don’t capture ready-made images. The data captured by the sensor has to be processed first. This happens automatically and instantaneously if you set the camera to shoot JPEG images. Many cameras don’t give you any other option. However, more advanced models like high end compact cameras, DSLRs and mirrorless cameras will also let […]

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.
Bits and bit depth explained
All digital data is made up of ‘bits’, and that includes digital images. In computing, ‘bits’ are either on or off, so there are only two possible values. But when you use them together the combinations are multiplied so you can record a much wider range of values. The number of bits used is the […]
