Foveon workflow: Blue Channel trick for Quattro cameras by using X3F Tools?

Since the blue channel trick doesn’t work with Quattro X3Fs, I tried to find out last week if there’s an alternative to SPP and that particular workflow. Just as a reminder: The blue channel trick is a workflow in SPP used for the conversion of Marrill X3F into black-and-white in order to reduce noise. This ...

SPP vs. X3F Tools: Noise and noise reduction (part 2)

After analyzing the noise of the Merrill sensor and noise reduction in SPP 6.3 and X3F Tools, I’ve taken a closer look at the X3Fs of the Quattro sensor. For this I’ve taken 7 X3Fs with the DP2 Quattro, with sensitivities ranging from ISO100 to ISO6400, and developed and converted them to DNG format with ...

SPP vs. X3F Tools: Noise and noise reduction (part 1)

I didn’t even notice how much SPP “pimps up” the X3Fs before I started to experiment with the X3F Tools converter which doesn’t know the many particularities of Foveon sensors and the many tricks in X3F image editing. Since it is too many insights that I could gain by comparing both converters, I’ve decided to ...

SPP 6.3 vs. X3F Tools (Kalpanika): coloured vignetting and noise performance

Most of these photos are nothing out of the ordinary, but in two shots, taken only seconds apart, it is possible to see ...

New photos taken with the DP2 and more insights into the Kalpanika alias X3F Tools

If you have never heard about Kalpanika, aka the X3F Tools, then you should have a go at this blog entry. In short, it is a X3F to DNG converter with excellent noise reduction, but at the moment there is still a long row to hoe. One of the current issues is the “Italian Flag” ...

X3F Tools: a cumbersome but very effective X3F-to-DNG converter

The X3F-to-DNG converter which was developed under the codename “Kalpanika” has now been released as “X3F Tools 0.53”. As far as I understood it, it was originally planned to make Kalpanika into a full-fledged RAW converter. This task was now abandoned as, according to the four-men-strong programming-team, there was no way to get rich with ...
