If your camera or preferred profile is not included on the list above doesn’t mean your camera is not supported. The open 3D LUT format of ImpulZ allows for any kind of image manipulation before and after a specific LUT is applied. The generic LOG & Rec709 profiles are a mathmatically derived average of a large number of cameras and people have been using these same generic profiles exclusively with our highly popular OSIRIS LUTs – the results should speak for themselves!

ImpulZ is all about flexibility which is why we’ve included multiple output gamma and color response profiles for each individual film stock. These are not just your average constrast curves that re-map luminance values but the results of complex non-linear functions that distribute brightness and saturation across the tonal range similar to what you would see in a photographic lab-print. The richness of color that we associate with photochemical film is exactly what we’ve been missing from existing film emulations which is why we’ve developed an alternate approach. These are our babies!

Output Gamma / Color
Film Contrast
Film Print

Film Contrast: Non-linear distribution of image saturation with a film-like gamma curve.

Film Print: Industry standard Vision 2383 film print. Medium contrast/saturation print stock.

VisionSpace™: Our custom gamma response which is ideal for starting your grade. Just enough contrast to get you started in the right direction without blowing out highlights or shadows and the same non-linear saturation as our film contrast profiles.

Cineon® LOG: Industry standard Cineon LOG compound gamma (95-685). This output emulates the gamma response of the DPX scans from the film scanners (Hasselblad Flextight X5 & ArriScan 4k btw). Resulting negative emulations are compatible with all film print emulations that expect a true cineon curve as input and provide a perfect starting point for fully fledged color grading. Obviously the quality of the Cineon LOG representation of your image data depends on your source footage. Our conversions will apply interpolation to make up values where your camera’s sensor hasn’t picked up any information and Cineon may not be the ideal workflow for highly compressed footage from lower end devices.

  Additional Conversion LUTs (Ultimate only):

  • Cineon to Vision 2383 (D50) FPE (Rec709) [medium contrast/saturation]
  • Cineon to Vision Premier 2393 (D55) FPE (Rec709) [more silver in emulsion – rich blacks/high sat]
  • Cineon to custom 35mm Fuji  FPE (Rec709) [color positive still film with custom print gamma]
  • Cineon to Film Contrast 01 [Non-linear saturation / print gamma – preserves negative colors]
  • Cineon to Film Contrast 02 [Bleach characteristics similar to profiles from another developer]
  • Cineon to VisionSpace

All conversions are optimized for Rec.709 2.2 viewing gamma while simulating DCI P3 white point (projected).

1. How is ImpulZ™ different from OSIRIS?

Let’s put it this ways: You could easily create your own version of OSIRIS with ImpulZ™! ImpulZ 3D LUTs contain only unprocessed negative and print film emulations that can be used to replicate an entire film workflow. With ImpulZ Ultimate you could start with a camera negative emulation, add your own seperate color grade and virtually print the whole thing back to film. OSIRIS is great for a quick and easy film look that has all of these steps baked in but ImpulZ puts YOU in complete control of the grade without taking creative license over your images. You can also combine the two packs and cook up your own unique color recipes – the sky is no longer the limit.

2. I don’t have a high-end camera. Will ImpulZ™ still work with my 8-bit footage?

Yes. There are even some visual examples of ImpulZ LUTs working their magic on compressed DSLR footage on this very site. While we do suggest that you denoise and dither your footage before applying any color corrections we’ve worked hard to make our LUTs as stable as possible while retaining a high degree of accuracy in the conversions. On Rec.709 video footage most of the conversions will be really subtle since your camera already applies a film-like curve to the image that usually doesn’t need any more contrast. The camera negative emulations with no print LUT applied will often look like an alternate picture profile – but with the beautiful color response and non-linear saturation of film.

3. How are LUTs different from filters or regular presets?

Presets and filters are usually limited to only work for very specific imagery, namely the kind of imagery they have been created for. Our 3D LUTs cover the entire color gamut by performing complex transformations to every single color that your camera is capable of capturing. The main benefit of 3D LUTs is that they contain pre-calculated tables of numbers representing the results of highly complex non-linear functions which would be too CPU intensive to calculate in real time. The three-dimensional cubes of ImpulZ apply more than 30.000 individual transform vectors that change all color attributes relative to each other.

Color Science - VisionColor

For example: When you’re making a curves adjustment it’s not very practical to add more than ~5 points to the curve. All other values in between are then interpolated by the software and while you can make similar adjustments to the individual color channels you’re not likely going to end up with a curve that has more than 20 or so adjustments. Now consider a lookup table that has not 20 but 30.000 individual transformation vectors stored in a color matrix that assigns new output values to each input value which is representative of a unique color. And since the cube in which the vectors are positioned is three-dimensional the color transformations are not limited to adding or subtracting colors based on luminocity. A three dimensional matrix transformation allows for all color attributes to be changed relative to another attribute for example: hue based on saturation or a certain hue with a certain saturation based on it’s luminance. Since these non-linear functions that are applied to the image data during such transformations are too complex for software to compute smoothly in real time, the results of these functions are stored in lookup tables.

The challenge in creating high resolution LUTs for image manipulation purposes is therefore to find the right balance between accuracy and stability. Since the matrix can pick up on super desaturated colors for example we had to find a way to not accidentally accentuate noise or other color artifacts. Even though this isn’t completely avoidable we’ve developed a technique for LUT smoothing that is based on an algorithm from statistical analysis to dynamically alter values above a predefined threshhold to avoid color instability.

4. Is it possible to upgrade from an inferior version of ImpulZ™?

If you want to upgrade to a superior version of the ImpulZ film pack (like Basic to Pro or Pro to Ultimate) shoot us an Email to support[at] and we’ll provide you with an upgrade code.

Downgrading is not supported.

5. Should these LUTs be used for print previewing and/or negative matching?

Know that all of our LUTs are optimized for Rec709 2.2 monitor viewing and are no substitute for custom film profiling services. The countless variables involved in capturing, film development, scanning and printing on both our and your end will inevitably intoduce discrepancies between our emulations and your references. Again, film profiling specifically for your end-to-end calibrated working environment is the only real way to get consitent results.

6. What’s the deal with the “film-look” anyway?

Obviously these LUTs serve a very specific (but still very broad) purpose which is to emulate a film workflow digitally. While the perception of color and beauty is ultimately subjective in a mind-dependent sense, the large majority of photographers, directors, colorists and others with an outspoken appreciation for light and color seem to agree on the superior aesthetic of film over digital for capturing and communicating stories and evoking an emotional response in the viewer.

We’re not so much conservative or nostalgic about a medium that once constituted a standard based on technological limitations as much as we believe that all art and craftsmanship including cinema is inherently subtractive. Out of all the millions of stories that could be told we are touched by those that focus on characters and events we can relate to; out of all the notes on the chromatic scale it’s the few that form a particular melody that aquire context and poetic meaning. The characterisitcs of film as a medium are much more representative of this subtractive nature of storytelling than the technically more accurate color reproduction of reality as captured by digital devices. Film compresses hues, limits saturation and is considerably softer and noisier than today’s high end sensors – all qualities that are hardly marketable to a crowd that has been hyped up for megapixels and other easily verifyable tech-facts. What we’re trying to do is preserve some of the things we love about a dying medium and translate them to the digital realm. Is applying an ImpulZ™ LUT to digital video the same as shooting on film? Definitely not. But it successfully approximates some of the color (and grain) characteristics really, really well.
