On today’s shoots it is increasingly common to find the figure of the DIT (Digital Image Technician). However, there is still some confusion about what exactly a DIT does, what their responsibilities are and, especially, what the difference is between a DIT and a Data Wrangler.
The DIT is a professional specialized in the digital imaging workflow. Their work connects the camera department with color management, monitoring systems, data and, increasingly, post-production.
Although their functions can vary considerably depending on the type and size of the production, the goal is always the same: to ensure that the image captured by the camera is controlled, managed and correctly transmitted through the project’s digital workflow.
In this article we explain what a DIT is, how this profession has evolved, what its main functions are and what differences exist between a DIT and a Data Wrangler.
What does DIT mean?
DIT stands for Digital Image Technician.
The profession appeared with the transition from analog to digital cinema, especially in the late 2000s, when professional digital cameras began to be incorporated en masse into film and advertising productions.
At that time, many of the technologies that are now a usual part of a shoot were relatively new: digital sensors, different codecs, new resolutions, RAW formats, LUTs and digital monitoring systems.
The DIT emerged as a specialist capable of working with these tools and helping the camera team integrate the new digital technology into the language of cinema.
The beginnings of the DIT in digital cinema
In the early years of digital cinema, the DIT had an especially technical component.
Their functions could include:
- Configuring the camera correctly.
- Adjusting resolutions and codecs.
- Analyzing the sensor’s behavior.
- Controlling exposure.
- Working with exposure latitude.
- Downloading camera cards.
- Making backups of the recorded material.
In many cases, the DIT acted as a bridge between digital technology and the traditional language of cinema.
They also had an important role supporting the director of photography, especially during the transition from photochemical negative to digital sensors.
The evolution of the DIT role
Digital cameras have evolved enormously.
Directors of photography, operators and camera assistants now have much more experience working with digital cameras, sensors, codecs and camera configurations.
As a consequence, the DIT’s work has also evolved.
Today, the DIT is much more focused on image management during the shoot, quality control and the design of the digital workflow.
Depending on the production, a DIT can be responsible for:
- Controlling exposure.
- Supervising the camera signal.
- Working with calibrated monitors.
- Managing color during the shoot.
- Creating temporary looks.
- Performing Live Grading.
- Generating CDLs and reference LUTs.
- Capturing color reference stills.
- Technically supervising the recorded material.
- Creating proxies, dailies.
- Designing or implementing the project’s digital workflow.
- Coordinating certain aspects between the shoot and post-production.
For this reason, today’s DIT is not simply a camera technician. It is a figure that can have an important participation in the management of the image from the shoot to post-production.
What does a DIT do on a shoot?
The exact functions depend on the project.
A DIT does not work the same way on a film or series as on an advertising spot, a music video or a smaller production.
However, there are a series of usual tasks.
Exposure control
One of the DIT’s fundamental responsibilities is to help maintain technical control of exposure.
To do so, they can use different monitoring tools, including:
- Waveform.
- False Color.
- Histograms.
- Signal analysis tools.
- Calibrated reference monitors.
These tools allow the camera signal to be technically analyzed and complement the visual observation of the image.
The DIT usually works in direct communication with the director of photography, helping to check that the image remains within the parameters established for the project.
Color management
Color is another of the fundamental areas of a DIT’s work.
During the shoot, different visual references can be established through:
- LUTs.
- CDLs.
- Temporary looks.
- Color corrections.
- Reference stills.
The goal is to ensure that the team can visualize a coherent representation of the image being built.
The DIT can work alongside the director of photography to adjust these references and maintain them across the different scenes and shooting conditions.
Live Grading on set
In certain projects, especially when creative control of the image during the shoot is important, the DIT can perform Live Grading.
This allows the appearance of the image to be modified in real time following the director of photography’s indications.
Grading can be used to:
- Adjust perceived exposure.
- Modify contrast.
- Control saturation.
- Adjust hues.
- Create a specific look.
- Maintain visual continuity between different situations.
The goal is not necessarily to do the final color of the film or the spot, but to establish a visual reference during the shoot.
CDLs and LUTs
CDLs (Color Decision Lists) and LUTs (Look-Up Tables) can form part of a project’s color workflow.
The DIT can create or manage these references to maintain a specific interpretation of the image during the shoot.
Depending on the established workflow, these references can later be used in dailies, proxies or at different stages of post-production.
Reference stills
Another usual tool in certain workflows is the creation of color reference stills.
These frames allow visually documenting how the image is being seen during the shoot.
They can be used as a reference for:
- Director of photography.
- Direction.
- Production.
- Agency.
- Client.
- Post-production.
In advertising, this function can be especially useful when different people need to quickly check the visual appearance being sought.
The DIT Station
The DIT usually works from a DIT Station, a workstation especially prepared for the control and management of the digital image.
The configuration can vary enormously depending on the needs of each production.
Among the tools that can form part of a DIT Station we find:
- Live Grading
- Specialized software such as Pomfort Livegrade allows color control and adjustment during the shoot.
- Signal analysis
- Tools such as Nobe OmniScope allow the signal to be technically analyzed through scopes and different monitoring tools.
- Proxies and dailies
- Software such as DaVinci Resolve can be used to generate proxies, dailies and different working versions of the material.
- Data management and verification
- Tools such as Pomfort Silverstack XT allow camera material to be managed, copied and verified within the digital workflow.
- Reference monitors
- A DIT Station can incorporate professional, calibrated reference monitors to achieve consistent visualization of the image.
- The choice of monitor and its calibration are especially important when the DIT is making decisions related to exposure and color.
- Cart or workstation
- All this equipment is usually integrated into a mobile workstation or DIT Cart, designed to be able to work efficiently in the environment of a shoot.
DIT vs Data Wrangler: what is the difference?
One of the most common questions on digital shoots is the difference between DIT and Data Wrangler.
Although both profiles work with the digital material generated by the cameras, their main responsibilities are different.
Simplifying:
- The DIT focuses mainly on the image and the image workflow.
- The Data Wrangler focuses mainly on data management and security.
In certain productions both functions can fall to the same person, but conceptually they are different profiles.
What does a Data Wrangler do?
The Data Wrangler, also called Data Manager in some teams, has as their main responsibility ensuring that the recorded material reaches the storage systems correctly and that the copies made are secure and verified.
Their usual tasks include:
- Downloading the camera cards.
- Making backups.
- Verifying the files.
- Managing production drives.
- Organizing the material.
- Preparing the material for post-production.
- Generating certain versions or dailies when the workflow requires it.
The main goal is to guarantee the security and integrity of the data recorded during the shoot.
Can a DIT also act as a Data Wrangler?
Yes.
In certain types of production, especially in advertising, music videos or smaller shoots, there is not always an independent Data Wrangler.
In those cases, the DIT can also take on tasks related to data management.
For example:
- Camera → download → verification → backup → organization → proxies/dailies → color workflow
This combination of functions means that the DIT’s professional profile can vary considerably from one shoot to another.
That is why it is important to define before starting a production exactly what responsibilities the DIT will have and which will correspond to the Data Wrangler.
The DIT in film and fiction
In larger fiction productions, the workflow is usually more structured and it is more common to find separate profiles.
In this type of production, the DIT can focus mainly on the image.
Their responsibilities can include:
- Live Grading.
- Exposure control.
- Signal monitoring.
- Monitor supervision.
- LUT management.
- CDLs.
- Reference stills.
- Communication with the director of photography.
- Coordination of the image workflow with post-production.
Meanwhile, the Data Wrangler mainly takes care of the recorded material:
- Card downloading.
- Backups.
- File verification.
- Organization of the material.
- Preparation for post-production.
In some workflows, the CDLs or color references generated during the shoot can later be used to generate the dailies.
The DIT in advertising
The DIT’s work in advertising has some particularities.
Advertising shoots can have very different workflows depending on the budget, duration, number of cameras and the needs of the client and post-production.
In certain shoots there may be a complete DIT and Data team.
In others, the DIT can take on an important part of the data-related functions.
An advertising workflow can include:
- Card downloading.
- Backups.
- Organization of the material.
- Creation of proxies.
- Generation of dailies.
- Color adjustments.
- Look management.
- Live Grading.
- Reference stills.
- Delivery of material to production or post-production.
In advertising, moreover, the DIT may find themselves working in an environment where director, director of photography, agency, client and production need to have a clear visual reference of what is being shot.
For this reason, speed and communication skills are especially important aspects.
The DIT as a bridge between the shoot and post-production
One of the most important functions of the modern DIT is precisely to serve as a connection between the shoot and post-production.
The material that comes out of a camera is not simply a set of files.
It is part of a workflow that must remain coherent from the moment of capture to post-production.
The DIT can intervene to ensure that:
- The camera is correctly configured.
- The signal is correctly monitored.
- The image is visualized according to the established workflow.
- The look is maintained coherently.
- The CDLs and LUTs are correctly managed.
- The data is correctly organized.
- The proxies and dailies respect the established workflow.
- Post-production receives the information necessary to continue the work.
This connection between the shoot and post-production is especially important in modern digital productions, where the decisions made during the shoot can have consequences at all later stages.
Why is it important to have a DIT?
A good DIT workflow can provide much more than a correct visualization of the image.
It allows establishing a working system in which camera, color, data and post-production speak the same language.
This can help reduce errors, maintain visual coherence and facilitate the work of the different departments.
In addition, the DIT allows the director of photography to have specific tools to analyze and control the image during the shoot without losing sight of the project’s visual goal.
The DIT in today’s digital cinema
Technological evolution continues to change the profession.
Cameras are increasingly advanced, RAW formats are more common, color workflows are more complex and post-production begins to be taken into account from the first phases of the project.
For this reason, the DIT has become a figure increasingly related to the complete digital image workflow.
Their work can range from the camera signal and monitoring to color, data, proxies and communication with post-production.
There is no single model of DIT.
Responsibilities depend on the project, the size of the production, the workflow defined by post-production and the needs of the director of photography.
The important thing is to understand that the DIT is not simply the person who downloads cards or makes backups.
The DIT works to ensure that the image and the digital workflow of the shoot function correctly.
Conclusion
The Digital Image Technician (DIT) is a specialized figure within digital shooting who connects technology, image and workflow.
Their work has evolved from the early years of digital cinema to become a profile that can intervene in exposure control, color management, Live Grading, monitoring, creation of visual references, data management, proxies and communication with post-production.
At the same time, it is important to differentiate their work from that of the Data Wrangler, whose main goal is to guarantee the security, integrity and correct management of the camera files.
Depending on the type of production, both profiles can work separately or certain functions can fall to the same person.
In any case, having a well-defined workflow before starting the shoot is essential to avoid problems and ensure that the decisions made on set can be maintained throughout the entire post-production process.
At Marqués del RAW we work with digital image workflows adapted to the needs of each production, integrating monitoring, color management, data and post-production tools to offer a professional and reliable working environment on set.
