Albert Renger-Patzsch. Die Ruhrgebietsfotografien

As stated is extremely interesting, but the image handling for and in printing is terrible! Some seem like small jpgs sharpened badly and upsampled others seem to have bad tonality and again seems to be also another artefact of sharpening or giving them more contrast.Based on that the catalogue, book, album however you want to call it should be taken for its indexing value.Also I think there was a way to make it bilingual at least.
