Cool Videos: Transferring Prints onto Wood and other Surfaces

I have to admit that this is brand new to me. While I knew that it is possible to detach the emulsion of instant film (Polaroid, Instax and Co) from its base and transfer it onto other surfaces, I was unaware of the fact that this can actually be done with as good as any ...

Foveon Workflow: How to Get More out of Color Photos?

As the Foveon differs greatly from the market-dominating Bayer sensor, you need to approach your photo-editing differently. On the one hand, this is because of the Foveon’s sharpness and sensitivity for bokeh fringing, on the other hand, only Sigma’s own RAW-converter, Sigma Photo Pro (SPP), is compatible with the raw data of the Merrill-Foveon. By ...

According to psychological study, taking photographs weakens memory

Do you remember the time you had to know telephone numbers and so much additional information by heart? It’s not so long ago, but it seems to me like it was in another life. Who knows in this day and age telephone numbers of his 10 best friends by heart? In the 21th Century we ...

Color vs Black-and-white

Inspired by this article on Fstoppers.com I have started thinking about why some photos look better in color, while others look better in black-and-white. I’ve also tried to comprehend the criteria based on which we can decided when to leave photos in color and when to convert them to BW. Ordinarily I find it easy ...

Tip for better Portraits: Squint your Eyes!

If somebody looks good on photos, we like to say she or he is photogenic. We blame it on charisma, which is a mysterious concept that cannot be quantified. If portrait-photographer Peter Hurley , who only recently published his second video-tutorial on the topic, is to be believed, good portraits aren’t magic but a precise ...

Foveon Workflow: How to Improve High-ISO-Usability?

Everyone has heard of the Foveon sensor being rather unsuitable for situations that demand high sensitivities. The higher you go with ISO, the less remains of the amazing sharpness. This is why many perfectionists use their Sigma cameras in the sensitivity range from ISO 100 to 400 and in the rarest cases to a maximum ...

Portrait Photography: How Crucial is the Right Angle?

Thanks to PetaPixel, I stumbled over a short, but highly insightful and funny video. In it, a Korean girl demonstrates the importance of camera angle for portraits in 14 seconds. Whether a person is photographed from above or below can make a huge difference. A difference of roughly 10 to 30 kilos. 😉 For photographers ...

VideoTipp: 360 Time-Lapse of the Milky Way and FAQ for Mars Curiosity Rovers Cameras

Just as last Sunday, I surfed the web and came across two very intriguing videos. The first one is a thrilling 360-degree time-lapse video by a well-known name in the astro-photography scene, Stéphane Guisard. It depicts the Milky Way as it floats across the sky.  The second one is a FAQ-session for the photo-system (system, ...

Aware2: the GIGAPIXEL camera

Almost a year ago, the first reports on the gigapixel camera (Aware2), which a team at Duke University worked on, were published. It was aimed at continually enhancing the design, until the 50 gigapixel mark was reached. Last year’s prototype was nowhere near it: 98 14-megapixel sensors, in a 75x75x50 cm cube, that are provided ...

Sigma DP3 Merrill Link collection: Reviews User Reports Sample Videos

Just like back then, when the 35mm f1.4 was introduced, I am grappling with my “addiction” again. The 35mm didn’t work out, I could only just resist. Currently, I am thinking of selling the 24-70 f2.8, which I hardly use anyway, and get a new Sigma DP3M. Thanks to the cashback on Merrills, my piggy ...
