crossover – Koraks tinkers

Twister fries – More RA4 curves, now with a dichroic head

The other day I set up a Durst M305 color enlarger that I temporarily have with me – just to verify it works. Since I had it out anyway, I figured I could make some step wedges with it. I’ve been doing this with LED light sources recently as well. I couldn’t resist the temptation to see what one might get from a dichroic head. It’s still a bit of the gold standard for darkroom color printing, after all.

Crossroads – A closer look at Kodak and Fuji digital RA4 crossover

Earlier, I wrote about digital RA4 papers suffering from crossover. I feel it’s time to revisit this topic, because I stumbled across some illustrations that make the issue more tangible. Let’s have a look at some theory and split some hairs!

Ginkgo leaves on expired Vericolor film

Rainy Sunday. Had the studio strobes setup for a bit reproduction. Some ginkgo biloba leaves I picked up in my parents’ backyard were sitting in a tiny vase, waiting. Some old Kodak Vericolor film loaded in cassettes. Heck…why not?

Balancing act – A brief look at ECN2 vs. C41 colors

When ‘Cinestill’ film came around, I just had to try it – although I have mostly used the original Kodak Vision3 stock instead of the remjet-less Cinestill variants. Frankly, I didn’t get along with it, and I’ve been quite vocal about it on the forums, too. But a couple of years after my initial bout of experimentation, I felt it was time for a re-assessment. Here’s a brief reflection on color balance of Kodak Vision3 250D film. After all, color balance is perhaps the most pressing matter when it comes to using Vision3 films for still photography.

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?

Sickly colors – the crossover issue

I like to print color RA4. That’s no secret. And I like to tinker. I’m not alone in this, and as a result, working with color film and printing color RA4 pops up regularly in one way or another on the photo forums. One issue that often meshes into technical discussions on ‘analog color’ is that of color crossover. Some people immediately ‘get it’, probably because they have experience looking at and analyzing color crossover. Others struggle with the topic and don’t know exactly what to look for. In this post, I’m going to try and illustrate the issue through some (digital!) mockups.
