According to the released image, which you can see above, the optical design of the lens consists of seventeen elements, which is quite a lot for a prime lens. What is important to note, ...

Noise reduction in photos with blurry backgrounds – a quick n dirty workflow

As I promised last week here is my „quick and dirty“ noise reduction workflow for photos with blurry backgrounds. Noise is most apparent in those blurry parts of the photo. In those areas which are in focus, the sharp detail “masks” the (luminance) noise. This approach is “quick and dirty” precisely because its aim is ...

Using a tripod or increasing ISO?

The cold season is here and it brings with it not only rain, fog, snow and icy cold, but also shorter days and tricky lighting. As a photographer you have a choice of either using a tripod, if you photograph motifs which allow the use of one, or increasing ISO. I never was a tripod ...

The first snow… but let’s stay warm inside!

Even for autumn, the past few weeks have been unusually warm: In mid-November it was 15°C in the streets and one could still see people wearing thin jackets instead of thick winter coats and wool caps. Eventually the Christmas decoration is installed, but the trees still have their colorful autumn leaves. However, out of the ...

Black Friday

Especially in the months after the Photokina we can’t always anticipate new lenses, cameras or updates to be released. After a series of new products the photo industry, of course, won’t rest, but there haven’t been a lot of new publications for a while. Maybe now is a good time to focus on one’s technique ...

City of superlatives

New York – hardly any other city in the world has become part of so many dreams as this one. Hardly any other city provides so many possibilities and impressions in a closed area. Hardly any other city is the setting for so many movies and series. Every one of us who has or hasn’t ...

NEWS – Where do our lenses come from?

Have you ever been wondering where the lenses in our camera bags are actually produced? I have, and that’s why I’ve started to do some research about where SIGMA products are being manufactured. During my research I came across the town Aizu in the Fukushima prefecture in the northern part of Honshu, Japan’s main island. ...

Halloween in the Big Apple

We all know that in the States Halloween is a much bigger affair than in Europe. Whereas only small groups of kids stroll around suburban areas in zombie or witch outfits, hunting for treats, and in the cities youngsters make an exception and dress up for a beer on Friday night, America goes crazy! In ...

What is better, SFD or a stack made of multiple photos?

I’ve discussed the SFD mode, which was introduced with Sigma sd Quattro cameras, late last year. Since I’m experimenting with Affinity Photo as of late, I wanted to do a little comparison of the program’s stacking feature and the SFD mode. In the following comparison we are going to determine which one looks best: SFD, ...
