If you want to learn more about RAW image format visit the very helpful guides Wikipedia, The Luminous Landscape, and Cambridge in Colour. The downside is that RAW image files can be very large indeed. Most professional photographers use RAW format, because it offers them maximum flexibility. Storing photographs in a camera's RAW format allows you to alter settings, such as white balance, after the photograph has been taken.

RAW format images contain all the data that is taken directly from the camera's image sensor before the software in the camera applies things like white balance, sharpening etc. It is different for every make of camera. RAW format is not really an image standard at all. Some, typically more expensive, cameras allow you to store images in RAW format. For more information about the PNG format see the PNG homepage.

It's the perfect file format to archive your photographs. PNG supports 8 and 16 bits / colors /pixels depth. Also, PNG can store gamma and chromaticity data for improved color matching on heterogeneous platforms. PNG is designed to work well in on-line viewing applications, such as the World Wide Web, so it is fully streamable with a progressive display option. PNG provides a patent-free replacement for GIF and can also replace many common uses of TIFF. PNG is an extensible file format for the lossless, portable, well-compressed storage of raster images. digiKam fully supports PNG images and the Batch Queue Manager can convert a batch of images from any supported format to PNG (and other formats) in one step. Unlike JPEG, PNG images do not lose quality every time you re-encode them after modification. Although your camera is unlikely to support PNG, some people like to convert their photographs to PNG as soon as they get them on their computer. It is a lossless format like TIFF but it is much more compact and saves disk space. PNG is an image format that was developed as a replacement for a number of older, in the 1990's widely used, image file formats.

A full description of these formats can be found at the Wikipedia. Many cameras enable you to select which of these formats to use. You can change the list of file extensions that digiKam will accept, see the Configuration section for more details.Īlmost all digital cameras store photographs in one of two formats: JPEG or TIFF.

If the file extension is in the list digiKam will show the file in the Image View, provided the appropriate library is installed. It does this by looking at the file extension on the files and checking this against a predefined list. At the very least JPEG, PNG, and TIFF should be available.ĭigiKam only displays files that are in formats that it understands.

This dependence on other libraries means that it is not possible to give a definitive list of all of the formats that will be available on your system. On most distributions you will find that a wide range of image formats are viewable within digiKam.

Which image formats are available will depend on the availability of these libraries on your system and, in some cases, on the way that those libraries have been compiled. DigiKam relies on a number of libraries and support packages to load and save image formats.
