Black-and-white-inkjet-printing

This paper is intended for all photographers who want to print black-and-white images using digital processes, but have been dissatisfied with their results. I describe a printing process that is kept as far away as possible from matters of taste, and that is based on rational, verifiable principles. In my opinion, the printing process must not interfere with the image processing at any moment. Image editing is a process for itself and so is printing. Normally the image designed on the computer monitor should not be provided with a priori correcions aiming at "correcting" the printing process. The ideal goal is always for the printed image to match the screen impression. Bringing the printing process to this level of maturity requires that measurements with a spectrophotometer come into play.

Reprography of historic book covers and illustrations

In 2018, my old friend Walter Wilkes, who taught typography at the TU-Darmstadt, told me about his project on book culture in the nineteenth century. He treated the typographic aspects while Eva-Maria Hanebutt-Benz part was cover design and illustration. The publication was to be illustrated and they were looking for someone to do the reproduction grahics. I promised to take over this part. The book was published by the Maximilian Society at the end of 2019. For this publication I reproduced about 150 book covers and at least as many original graphics.

Descreening - removing printing screens

If a rasterized image is reproduced, and then this reproduction serves as a master for an image that goes through a printing process, a moiré pattern will become visible in the final printed product. It is therefore imperative that artwork be freed from screens. Unfortunately, you won't find a descreening tool in Photoshop's on-board toolbox. The blur tools are not suitable because they blur too much image information in addition to the halftone.  We show how to selectively eliminate the dot screen.

Digitizing slides - A DIY project for photo geeks

Like many others, I have slide magazines filled with old memories piled up in a closet in the basement. Of course not all slides are worth preserving, but some are. There are inexpensive digitizing services available today. However, I first would have to sort out the slides that are worth preserving. That means I would have to go through every magazine. If I take this time, I could as well digitize the slide in question myself. What would be a good and fast technique to tackle this?

Making your own photo book - another DIY project

Designing and producing a photo book is a complex project that consists of a long series of decisions. The individual decisions are often interdependent. We go through them step by step and then deal with the technical aspects.

The above essays have a fair amount of "geek-ness". But I also take pictures in between. For example
