Nowadays, the popularization of SLR (Single Lens Reflex) bodies based in the XX Century classic designs are being confronted to some new bodies named as …
Image Processing for Hybrid Processes II – Digitization with Scanner
Although the technological obsolescence is nowadays a serious constrain for a suited digitization, specially with high end level scanners, I will explain some hints and tips useful for the current medium and high level scanners still available. The first question to be aware about the scanner performance is the actual possibilities to penetrate a given …

Image Processing for Hybrid Processes I – Introduction
Many old or classic photographic processes operates from a negative or a positive at life size of the final print. These intermediate negatives or positives can be traditionally elaborated on photographic film or, taking advantage of the digital image technology, inkjet printed on some suited transparent media. This later system need a previous digitization of …

Heliogravure VIII – More About Etching
In a previous post have been exposed a general method to reduce the number of etching baths and rationalize the relationship between the total etching time and the partial etching times in the respective baths. Here we will analyse a sequential fine tuning of a couple of ferric chloride baths having previously determined a total …
