The colour balance of colour images can be adjusted in a similar way by selecting the colour to be adjusted from the pulldown list in the adjustment window. This is a very convenient way to fine tune colours for scanned images. Especially skin tones often need adjustment. Over- or underexposed images can also be cerrected to a certain extent. Very often new information must be added to images.
Typical additions are arrows, markers and text.
In the first method all annotations will be made as bitmaps and they permanetly overwrite the image. Removing or moving this kind of annotations is very difficult because the information under the annotation is lost. In the second and preferred method the image is imported to a presentation program and annotations are added as separate objects overlaid on the image. The annotations can freely be moved around afterwards without the image information being overwritten. Bitmap images can easily be imported to PowerPoint using the clipboeard.
