Different kind of print – Making PCB’s at home

Sometimes (frequently…) I get sidetracked from photography because I need some kind of equipment or trinket. In such a case I could just go online and order whatever it is that I believe I need. But most of the time I end up DIY-ing something, especially if it’s an electrical device. And that involves making PCB’s. Out of necessity, I have become reasonably good at making these at home. Let me share my current way of working, as it involves a few tricks that make this a little easier.

Pixels, not grains – Why RA4 paper is ‘digital’, and why this matters (not?)

Look at the back print of some papers, such as FUJIFILM’s Crystal Archive Supreme HD, and the word ‘digital’ features prominently. Indeed, I’ve been told that current Fuji RA4 color papers are exclusively intended for digital exposure. But does that mean we can’t use them anymore for optical enlargements?

Between the lines – The importance of interlayers in RA4 color paper

‘Today I learned’…a lot, in fact! More than enough to fill a couple of blogs, but let’s start with this one. Did you know that color paper has layers that you can’t see, that are actually designed to be invisible, but that play a huge role in the visual aspects of the paper and the images on it? Well, now you do! They’re the interlayers, and they are quite essential, as it turns out. I’ll try to explain.
