Description Thomas Bettler 2013-03-31 23:47:49 UTC
I'm using digikam to batch convert photos to black & white (sepia) from the album "a" to a new album "b".

It processes the images in the batch queue. The resulting images are full black without any white or gray.

Expected Result:
Black & white images as resulting from the single image conversion by the showfoto single image process.

Reproducible: Always

Steps to reproduce:
1. Open a new batch queue in digikam.
2. Select any images to process.
3. Select the black & white conversion tool.
4. Choose any parameters - i.e. the default ones.
5. Run the batch process. - Here you are.
