Aching, flaking – A persistent problem with carbon DAS highlights

The problem that just won’t go away: disappearing highlights on DAS carbon prints. Twice so far I’ve declared this problem solved on my blog, only to have to revoke my ‘eureka’ shortly afterwards. Over the past few weeks, I’ve been systematically testing the process to find a cure. So far, to very little avail, I’m afraid. But perhaps that this writeup will (1) help me re-think the problem and (2) it’ll give some hints to anyone else struggling with DAS carbon problems by listing factors that can/should be evaluated.

Collimated vs. diffuse light – a cyanotype example

On a forum, someone asked how to get their cyanotypes made with 3D objects instead of a negative crisper. The fundamental issue at work here is how collimated or diffuse the light source is. Here’s a quick example of the difference between both.

DAS right! – Solving the teething problems of DAS carbon transfer

Previously I wrote about trouble I was running into with DAS-incorporated carbon tissue. I just couldn’t get those tissues to transfer properly. Well, looks like I figured out why. In the process, I received some useful advice to boot, and perhaps there are some myths being established as well. Are you starting out with DAS and running into issues? Maybe some of the info in this blog can be of help.
