Scenes with a high dynamic range can be challenging to work with - either you risk blowing the highlights or the shadows are way too dark. Let's learn how to compress a high dynamic range scene in darktable using both filmic rgb and sigmoid to compare how each of these tone mapping modules works.

Shooting far-away subjects often results in haze, characterized by a loss of contrast and a loss of detail. Fortunately, sigmoid is well-suited to recover this contrast and pairs well with the haze removal, local contrast, or diffuse or sharpen modules to reverse the haze. Let's dive in and see...

Motivation This is a very short one – but I felt like sharing this with the world. I was playing around with the humble long-tailed pair transistor amplifier in LTSpice. I noticed something interesting – not only can it be used as a differential voltage amplifier, but it seems it can also be...

At first glance, the flower above might look fine. However, there is a hue shift going on which makes the flower look green/yellow even though it should be an orange/yellow. This phenomenon is present on a huge number of the JPEGs generated on-the-fly (also know as out-of-camera JPEGs) from...
