Image enhancement

We always recommend for photobooks to disable automatic image enhancement when editing images.

In the automatic image enhancement, various adjustments are made in the image data with the aim of visually improving the image.

The most important image improvement steps include the exposure and color correction, which changes the brightness and color throughout the entire image. The exposure correction is used to lighten underexposed images so that more details are visible. The color stitch correction is used when an image has been taken with artificial light, for example, and therefore has a strong yellow color. Well-exposed images with good white balance need fewer corrections.

After these so-called global corrections, local image adjustments follow. For example, dark areas of the image and shadows in the image are lightened, in order to make the under-exposed faces more visible in the backlight. Also, very bright image areas, such as white clouds somewhat darkened, to allow a better drawing of the details. Local adjustments are applied to a smaller extent, for example in order to make the skin tone of different faces appear more pleasant. Finally, the sharpness of an image can also be adjusted somewhat depending on the image area.

Depending on the image class, further image enhancement steps can be performed, such as the automatic correction of red-eye or the removal of coarse grained noise in images recorded with high sensitivity.

Although many corrections are also a matter of personal taste, the exposure and color correction, such as the lightening of shadows, in most cases lead to a marked improvement in many images which would not be satisfactory in the original state.

 

Self-resolved PNGs

If you use PNGs that you have created yourself and inserted into the software and which have a transparency, we recommend to always disable the image enhancement.
