Sigma sd Quattro RAW development: what’s better, SPP or Lightroom?

I’ve tinkered with Sigma sd Quattro’s DNG support for quite some time now. On paper it’s great to have the option to develop Sigma RAWs in other programs. But what can you expect if you shoot DNGs with your sd Quattro and subsequently develop them in Lightroom? Is it silly to expect an equivalent output ...

First images taken with my Sigma SD Quattro

Yes, you read that right, my Sigma SD Quattro has arrived and I’ve already had a chance to take some photos with Sigma’s very first “EVIL”. It’s too early to go into everything that was changed or improved in comparison with the SD1 Merrill. We are talking about a change of concept, from a DSLR ...

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

Yesterday I uploaded a couple of photos which I had taken with the DP2 Quattro as X3Fs, then converted into the DNG format with X3F Tools (Kalpanika), and edited in Lightroom 5.7. 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 ...

SPP 6.2.1 vs 6.3: is it possible to tease out more sharpness of the X3Fs with the newest version?

I was curious when Sigma launched SPP 6.3 and the change log claimed that the algorithm had been improved to make the Quattro X3Fs even sharper. Since optimising the RAW converter usually only improves the image quality a tiny bit, I was not expecting to see a huge difference when comparing 6.3 and 6.2.1. I ...

Hopefully I will get my hands on my own DP2 Quattro soon, for that I can provide you guys with some pictures comparing the Merrill. Inbetween this summary of relevant links must do the job. There are many more interesting threads to be found on DPReview, but I had to draw the line somewhere. 🙂 ...
