Quattro and the blue channel trick revisited

There is hardly a photographer who shoots with a Sigma camera who doesn’t know about the blue channel trick. Those, who have never heard about it, should read this blog post of mine. The tl;dr version is this: it’s a workflow trick for black and white conversion, with which you can improve the noise performance ...

Sigma Photo Pro: what does the detail slider do?

I remember when after a long break from photography I bought my Sigma sd Quattro and installed SPP and that after starting the application the first thing that caught my eye was the new “detail” slider. In the spring of 2016, when I was still shooting with my SD1 Merrill and using a at the ...

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 ...

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 ...

Foveon Workflow: How to increase High-ISO headroom for color photography?

As I announced a couple of days ago, today I’ll present a workflow that further increases the High-ISO range of Merrill and Quattro Foveon sensors when taking color pictures. In contrast to the blue channel workflow, which is able to improve noise performance in black-and-white images almost without any side-effects, this particular workflow is a ...

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 ...

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 ...

SPP 6.X.X: Color Mode „Portrait“

With the 6th version of SPP additional color modes were introduced. Currently Sigma’s RAW converter has 10 of these modes, whereby some of them – like “Sunset Red” and “Cinema” – are somewhat gimmicky. With the Merrills and SPP 5.X.X „neutral“ was, or rather still is, the color mode of my choice. With the Quattro ...

Photos from the previous Photo Tour with the DP2Q

Once again, I was out taking pictures with the Quattro – this time in very soft and flat light. On the whole, I am happy with the results. Slowly, it dawns on me how exactly I need to edit pictures taken under a cloudy sky. For me, the difficulty so far was to correctly adjust ...

Orange and Yellow – the Foveons Perceive these Colors differently than I do

When I tested the „pre-Merrill“ SD1, I realized that its sensor perceives the colors mentioned in the title more greenish than I do. As I later found out, this is partly due to the automatic white balance, which tends to have a green cast with the SD1, SD1M and DP2M. But even if the white ...
