Capture

If minimalism is the primary criteria for you, then this pretty little theme designed specially for personal blogs and portfolios is what you were looking for. As you may see, the Capture theme does not leave any free spaces and uses the asymmetrical grid, which is back in trends these days.
Even though Capture looks relatively simple and even basic from first sight, it can offer a powerful gallery module that supports such features as asymmetrical gallery grid, multiple effects, text, buttons, meta-data, and other useful features that are typically present in advanced themes for photographers and artists. With the help of Capture back-office tools, you can also edit your images and videos in real-time and edit the gallery grid in a sandbox mode.
