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 ...

Sigma News & Rumors: 30mm f1.4 for mFT / E-mount, 50-100mm f1.8 for APSC and MC-11-adapter leaked, new SPP version and DP Quattro firmware available

The Sigma lenses that were “teasered” not even one week ago by Austrian photo retailer Escher Foto (aka “Sigma Austria”) were leaked on the Japanese photo blog digicame-info.com. The “small, fine” one, as it was described on Sigma Austria’s Facebook page, is a 30mm f/1.4 DC DN Contemporary prime lens for micro 4/3 and Sony ...

Do you use the shadows and highlights sliders in SPP?

The best known quote by Socrates “I know that I know nothing” describes my attitude to Sigma Photo Pro very well. Just when I think that I know the RAW converter by heart, I discover something totally new. 😉 For instance, I haven’t paid any attention to the sliders “shadows” and “highlights” for a very ...

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

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 ...

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 ...

Sigma News & Rumours: Sigma introduces the 24-35mm f/2 Art lens and launches SPP 6.3!

The rumours that came up yesterday where true – today Sigma introduced the 24-35mm f/2 DG HSM Art! For us users of the APS-C format the zoom is less interesting, since the already available 18-35mm f/1.8 DC HSM Art already covers a wider zoom range and is faster by 1/3 of an aperture stop. As ...

Was SPP always so fast in Monochrome Mode?

Satisfied with the photos taken during the last photo walk, I’ve decided to convert most of the photos taken this time around to black-and-white as well. Although I’ve developed black-and-white and color photos side-by-side many a time in the past and always felt that the monochrome mode was faster, I’ve never observed such an extreme ...

Sigma news and rumours: SPP 6.2.1 and firmware-updates for the DP1Q and DP2Q are now available!

During a talk two weeks ago, the owner and CEO of Sigma, Kazuto Yamaki, said that a new SPP version and firmware updates for the DPQs would be released. These updates, which increase the quality of the pictures and speed up the AF are now available for download. Since I do not dispose of any ...
