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: 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 ...

Foveon workflow: Looking for the Blue Channel trick for Quattro cameras

The “blue channel trick“ is a workflow in Sigma Photo Pro (SPP) that clearly increases the usable sensitivity range of Merrill Foveon sensors. The “trick” is actually not a trick as you use the tools that are included in SPP anyway and that you can find easily. The only thing you’ve got to do is ...

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 ...

As a photographer who favours normal focal length you can get used to the 35 mm focal length

I was having a tough time with Sigma’s 24/1.4 Art in the beginning because I didn’t get along with its focal length. I’m used to taking photos with a normal focal length or even longer focal lengths such as the DP3M’s 50mm (which is equivalent to 75mm in full frame terms). But it’s not like ...

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 ...

Sigma News & Rumors: first sample pictures of the 150-600mm S at wide open aperture and Foveon-like 36 layer sensor, not by Sigma

Sigma-Rumors reported a few days ago about the first sample pictures of the new 150-600mm F/5-6.3 Sports lens. Now, the chinese website qicai.fengniao.com published the first samples at open aperture – just in time for the retail start in mid October. These brand new samples, shot with a Canon 5D Mk III, can be browsed ...

Status quo of the ‘Foveon-Look’

The Foveon look is a broadly discussed topic in photography forums. There are the ones who recognize and like it at first glance, and then there are others who don’t see it, wondering what all the fuss is about. Conspicuously often, it is referred to as “the Foveon look”, as if there’s only one. I ...
