Photographer & Printmaker / A Hybrid Place About Early Photography and Digital Imaging
En la búsqueda de un mejor resultado, se van introduciendo pequeñas modificaciones de método en la práctica del heliograbado. Algunas son fruto de la re-lectura de textos clásicos, mientras que otras son consecuencia de hipótesis de trabajo que después de no pocas pruebas, se confirman con los resultados. Cabe aquí insistir en el hecho de …

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 …
Single or binocular loupes are often used to observe the effects of the etching on the surface of the copperplate. Depending on the kind of resin or screen used, it is sometimes difficult to view in detail what happens at this level. In some cases would be very useful to take a picture in order …

Some days ago its been a discussion in Facebook about the correct word defining different printing techniques. It is a periodically recurrent discussion about the correct word to name a photogravure print, depending on the way it was generated. A paragraph in the discussion said: “... referred to her etchings as engravings--a much different technique.” …
