Selective White Balance


Adjusting the white balance of a photo is a fundamental skill needed when developing RAW files. In this tutorial, we take it a step further and show how to use darktable's powerful selective white balance to use different white balance settings on specific parts of the image. Typically, this would be used to correct the color from multiple light sources (each with different color temperatures), but in this case we'll use it to keep the subject neutral while adding a creative effect to the background.


Highlighting The Subject Using RGB Channels


Mastering the channel mixer allows you to not only adjust white balance, but also creatively color grade a photo to set the mood, change the luminosity, and make local adjustments to specific areas of the photo. In this example, we use color calibration to highlight a subject when the surrounding content, in this case the green foliage, is naturally brighter than the subject and thus pulls your focus away. We can counteract this using channel mixer in color calibration.


The Case For Q


With the season finale of Star Trek: Picard, we finally learn if Q is a friend or a foe. Let's review the case for Q as a friend of Jean Luc Picard, and reflect on John DeLancie's phenomenal performance in Farewell.


Unlimited Love


I've been eagerly awaiting the release of the new Red Hot Chili Peppers album for quite awhile, and Unlimited Love thoroughly surpassed my expectations. Not only is this a new RHCP album, which is always exciting, but this one is imbued with extra quality, polish, and creativity. As Flea described it, "this is the best of us". Read on for a full review of the album.


Color Contrast


When you think of contrast, you are probably thinking of luminosity, but color contrast can play an important role in creating a vibrant, dynamic image too.


Directing Attention


Darktable's powerful parametric masks, combined with the ability to layer multiple instances of a module with a separate set of adjustments applied to each, makes it possible to quickly make high-impact edits. In this example, an additional exposure module directs the viewer's attention to the picnic table, the focal point of the image.


And So It Begins... Again

Why I'm a Fan of Mark Knopfler's Music

There are many things I like about Mark Knopfler's work, both his solo albums as well as Dire Straits:

Personal Geography

The way he weaves memories from his own life (even seemingly mundane things) brings a personal connection to his music. For example, taking the train in Southbound Again, remembering …
