When the intermediate film print was created, film labs could “push” or “pull” an image to increase or decrease the exposure (luminance) and adjust the strength of the red, green and blue printer lights to change the color balance and enhance or correct the footage that was originally captured on set.

The process of scanning film to create a Digital Intermediate (DI) started popping up in the early 1990s to allow computer generated visual effects (VFX) to be incorporated into film footage. The final images were then printed back to film and cut into the final edit. The high cost to create and store these large digital files limited the DI process to effects shots.

As technology advanced and the cost of computing fell dramatically, so did the cost of the DI process. In 2000, O Brother, Where Art Thou? utilized a digital intermediate for the entire film despite having relatively few VFX shots. Along with advances in computer generated imagery came advances in digital color manipulation. Unlike the film printing process that changed the color of the entire image in broad strokes, digital color correction allowed colorists to only affect the parts of the image they chose, giving them a level of color creativity that was not possible before. With the emergence of digital editing platforms, increased visual effects usage and digital color correction, the DI process became the normal way of doing post by the late 2000s.

With today’s digital video cameras, the color balance (commonly know as white balance) will be set electronically in a camera to match the scene’s lighting prior to rolling. Most commercial and corporate motion media projects are captured digitally, and on set you’ll generally have a client monitor that allows you to get a good idea of what the final image will look like. If you don’t, request one. It’s a great way for the creative team to get on the same page when developing a look for the final piece.

Depending on your capture format, your ability to manipulate the image in post may vary. Most digitally recorded image settings are “baked in” during capture, which can limit your options for dramatic changes in the color suite. This is of little concern if your image is exposed and color balanced properly on set and your creative director isn’t planning to completely change the established look during post.

Some digital cinema cameras now record in a RAW format, which allows for greater flexibility in image manipulation and white balance adjustments during post production (the Arri Alexa and RED Digital Cameras are two examples of RAW cameras). While some cameras may produce great looking imagery right out of the box, shooting RAW means incorporating a color session into your post pipeline is critical.

Bottom line: If you’re looking to create stunning imagery that wows your audience, no matter how your image is captured, a color grading session is a the best way to get the most out of your images.

Here’s the short description for the two:

Motion Graphics equals animated graphic design. Common uses include title sequences, lower third graphics for interviews and informational art cards.

Some examples of Motion Graphics work includes:

• Gates Foundation – G20 Summit
• Is That A Fish In Your Ear? – David Bellos

Visual Effects combines existing footage with computer generated imagery to create realistic scenes. Common uses include sky replacements, logo removal and including environmental effects, such as snow, fire, smoke and lightning.

Some examples of this type of work include:

• VOLKSWAGEN Hedgehog
• Justin van der Lek – VFX Showreel
