What is RAW format

Raw format is the uncompressed and unprocessed data file captured from the image sensor of a digital camera. It is considered as digital photography's equivalent to a negative in film photography. One key advantage of RAW format is allowing the photographer to postpone applying several adjustments, therefore giving more flexibility to later on apply the adjustments themselves in such a way that best suits the image. RAW files give the photographer far more control when it comes to picture settings.


Enhancing digital camera photos using RAW data support

With RAW data support, you can directly edit raw image data from popular digital camera formats. PhotoImpact lets you decide how to open RAW files by using essential parameters such as color temperature and exposure compensation. You can then use the same settings for batch processing in opening multiple RAW files. To open RAW files, select File: Open and select the file you want to open. This will take you to the Open Camera RAW File dialog box.

    White balance Calibrates colors to correctly display white and other colors according to different lighting conditions. You can adjust white balance through:

    Scenario Lets you choose the lighting condition applied to the image. Choose from default scenarios (e.g. As Shot, Daylight, Tungsten etc.) or choose Custom to manually adjust the color temperature.

    Color Temperature Sets the degree of warmth or coolness of a lighting source while the photo was taken. Lower value means warmer lighting(e.g. indoor), whereas higher value means cooler (e.g. outdoor).

    Tint Adjusts the color balance between green and magenta. Dragging the slider to the right increases the degree of green, while dragging to the left increases the degree of magenta.

    Exposure compensation Adjusts exposure variables for lighting issues.

    Reduce noise Sets the noise degree for luminance and color.
