Composition & DepthThere are many aspects to the art and craft of cinematography. There is a technological component to it, of course, and that’s something that we talk about frequently. However, most people agree that it’s not the equipment that is used, but instead, how it is used that determines the efficacy of a given cinematographic piece. Of the many artistic facets of the craft, perhaps the least understood is composition. Many of our most coveted compositional techniques and theories come from history’s greatest visual artists, and they are entirely fascinating and useful once understood. Unfortunately, learning about them can be about as interesting as watching paint dry. Luckily, the following video on composition is not only informative, but it’s also, dare I say, entertaining.

Shot depthSince we shoot on a 2D plane, creating the illusion of depth is an important aspect of cinematography. Sometimes a few blocking choices, like filming your subjects against walls, can (not always) make a scene look flat and uninteresting. So, let’s take a look at what gives a scene depth, and if there’s a lack thereof, what options you have to bring your subjects from the dark and boring abyss of the background.  More »

Light field cameras could be the next big thing in photography and/or video, but as of right now, there is only one company selling anything that can achieve the affect: Lytro. If you have been wondering if this effect could be recreated with the DSLR you already own, the answer, as it turns out, is yes. The Chaos Collective, a group of internet futurists, has created a way to achieve the exact same effect as the Lytro camera with any DSLR, and has even created a way to embed the adjustable photos online.

Lytro cameras already allow us to do something that, while (apparently) scientifically possible, seems to invoke more Gandalf than optical physics — which is to manipulate focus, dynamically and after the fact. By sampling the whole ‘light field’ within the field of view, they are truly fascinating iterations of the tools we use daily. This has some pretty interesting implications for the future of photography, not to mention videography — but Lytro isn’t stopping there. In fact, you can not only interactively shift your focal point, as you could before – but you can now, to an extent, alter the actual perspective of your shot as well, in real time — not to mention apply filters which also react in line with the company’s “living picture” aesthetic. For a demo video and some interactive examples, read on. More »

Exposure is one of the most important aspects of shooting with DSLRs. If you’re new to shooting with digital cameras, it can be a bit overwhelming to fully understand all of the terminology and the options for controlling the exposure of the image. Film is pretty straightforward, where the film speed (or ISO, ASA, etc.) does not change. Shooting pictures is a bit more complicated, as the film speed can change, so you’ve got aperture, shutter speed, and ISO as three different settings to affect exposure. Shooting video is a bit different, as the shutter speed of DSLRs will typically not go below 1/30 of a second. We’ve got two videos explaining exposure and control, with the first being a beginner’s guide to overall exposure, and the second explaining what happens as you stop down your lens. More »

Years ago a reader emailed me about plenoptic cameras, also known as light-field cameras, which allow an image to be refocused after the picture is taken. Sometimes referred to as a 4D camera, this crazy technology is now headed to a consumer camera from new manufacturer Lytro. News of this development, which utilizes technology first seen in a 2005 Stanford research paper, hit the internet last week, with Lytro now taking reservations for the device. Check out the refocusable images in action, and let me know what you think — game-changer or gimmick? More »
