Automatische Dunstentfernung für mehrere Dateien ?

There is not batch process for 'auto haze removal'.

However, if you have several files to edit at the same time, you have two ways to do a similar enhancement:

- From the organizer, you select your files (say a dozen or so...) and click on the 'Instant fix' button on the bottom bar.

You choose the last icon in the right panel: the clarity slider. (new in Elements 15).

- From the editor, you select the option to 'Open in camera raw' and open your batch of files. You select all (Ctrl A) and play with the clarity slider.

The effect is more subtle than the 'dehaze', but dehaze is really for very hazy pictures, not for enhancement of local contrast. I always use it on a layer copy and play the the layer opacity to tone down the effect (which may be very coarse).
