DIGILOG video presets and how they work.

The film look has been cherished throughout photography’s long lived history. The look of the color, contrast and grain that analog film gave us takes us back to an era that provided a timeless quality to images that is still sought after. That gave rise to many greats such as Henri Cartier-Bresson and Gordon Parks. With DIGILOG video presets videographers and content creators alike could now enjoy the look of photographic film that we’ve grown to love in their video content

What’s the difference between film photography and digital photography ?

There are many aesthetic differences between film and digital photography and they are all a direct result from the physical medium used to record the image. Film photography creates the image by recording to a negative which is processed with chemicals and enlarged to a print. The grain and texture we see in the image is a result of the light absorbing silver halide used in the print that forms the image. Digital cameras however, take a different approach by converting wavelengths of light into an electric signal to create the image. This affects the way colors are saturated, grain is produced and the overall look of the image. Digital has made many advancements in comparison to film including better detail in the shadows, improved color accuracy, sharper images and the ability to view recorded images instantly. Digital photography is in many ways the evolution of film photography.

Why recreate the film look if digital photography is its evolution ?

While digital may have its technical advantages the many nuances of films image such as how it handles bright portions of the image and color are still subjectively pleasing to many photographers and fans of photography. Many iconic images that helped shape the priniciples of photography as we know it were shot on many types of film all complete with their own color balances and color combinations. The film era lead to the rise of companies like Kodak, Fuji and Agfa who were known for their pleasing renditions of color. So while digital photography has improved on a technical level, by adjusting the color response of the film’s negative, the afforementioned film manufacturers were able to provide pleasing images by manipulating what we know as memory colors.

What are memory colors ?

Memory colors are the colors that we know things should be. The sky should be blue, grass should be green, and a stop sign is red. These are colors that if shifted from the colors we know them to represent in reality will immediately stand out as being incorrect. Ironically since color is subjective what human beings perceive as normal in terms of color varies from person to person. This allows our brain to “fill in the blanks” and guess what color something should be within its visual context. Digital sensors however see color objectively as well as predictably no matter the scenes visual context. With the DIGILOG LUT’s one of its primary purpose is to adjust the incoming data from your source camera to output vibrant,saturated,film like color without creating jarring shifts to the memory colors.

How does it work ? 

DIGILOG presets are high resolution LUT’s (look up tables) that are compatible with a wide range of applications from Adobe Premiere, Final Cut Pro, LumaForge and DaVinci Resolve to name a few. To use them, all you have to do is load the file into your application of choice and the editing software does the rest of the work. 

What is a look up table ?

A LUT is short for “look up table”. Look up tables contain a variety of advanced adjustments to the entire look of the image. Some of these adjustments are so complicated in nature they contain changes to the hue, saturation and luminance of the image that are outside the scope of the tools built into some video editing applications. This gives you greater control over the final image and in the case of DIGILOG it is the medium of choice for maximum application compatibility and image quality.

Is it compatible with my camera ?

DIGILOG is compatible with all cameras that shoot in the industry standard rec709/SRGB color space. A majority of the images we see and even our computer and phone displays are built around the rec709/SRGB standard. 16.7 million colors exist within the srgb color space triangle composed of shades of red, green and blue. What the LUT then does is change one color visibile within the SRGB/rec709 triangle that your camera produces to the shade of color designated by the LUT. So it can change the fire truck shade of red in your image to a ferrari red, sky blue to steel blue etc. thus making it compatible with any and every camera that complies to the rec709/SRGB standard.

What software is it compatible with ?

Any NLE (non linear editor) that supports LUT’s such as Adobe Premiere, Final Cut Pro, Davinci Resolve and Luma Forge for iPhone iOS.

Does it work with animations ?

Yes. It will work with animations. Many CGI artists have incorporated LUTs into their workflow to match the look of their shots to their computer generated graphics.

Can Black & White film benefit from DIGILOG ?

DIGILOG does offer black and white conversions from color video. The looks are based on Ilford black and white high contrast film. Some of the black and white film are even tinted in the highlights to add character to the image.

How does DIGILOG benefit my current workflow ?

One of the many benefits of incorporating LUT’s into your workflow is the consistency of color that it brings to a project. It can help you arrive at a uniform look quickly which saves you time in post production.
