            </orderedlist>

            We recommend this sequence of image editing steps to ensure optimum photographic quality for the end product.
            In particular, never do sharpening before the last step. And we recommend using a lossless format like PNG or TIFF for storing photographs.
            Otherwise you'll lose a bit every time you save the results. If you can afford it, use 16 bit/channel for your best shots.
            If you want to change color space, in particular if you want to work in CIEL*a*b, 16 bit per channel are required to avoid truncation effects.
            </para>

            <para>If you swap step 4 and 5, which is well possible if the initial contrast is already very good, you can do the first 4 adjustment in the same tool, the white balance</para>

            <para>Many of the tools you may need for photographic editing are included with &digikam;. Their description follows here. </para>

            <para>
                All Image Editor tools like Sharpen, Blur, Noise Reduction, Refocus, Unsharp Mask, &etc; use a common dialog style that previews the effect before applying the filter to the current image. Below you see the <quote>Apply Texture</quote> tool in action using this common dialog layout:

        From there everything is simple, select a RAW image and open it in the editor. The color management widget will be displayed after the image has been processed in order to adjust color rendering. Without color management all images are very dark, this is normal. You can experiment the various profiles you have in order to select the best input profile according to your image (some tends to be very neutral, even a bit dull, some gives more saturated results, &etc;).
