After using Zacuto’s Gratical EVF on a few shoots recently, I wanted to take a more in-depth look at the exposure tools and LUT functions that can be extremely valuable on set. I already knew I liked the versatility of the viewfinder and the user-friendly interface, but I wanted to see how these advanced tools could benefit my image and my set. In my first video, I use the Zacuto Gratical HD with a Sony FS7, connected via HD-SDI, and then to a TVLogic 5.6″ monitor. I show how to calibrate the viewfinder and how to best use the waveform and vectorscope tools. I also demonstrate to use the false color and zebra overlays to ensure a properly exposed image whether sending a Log or Rec. 709 signal. In addition, I explain how to set up user buttons to maximize the use of these exposure tools in order to judge exposure based on a post-LUT and Log image.

At IBC this year, Teradek released their new COLR wireless LUT box. This compact system can take in HD-SDI or HDMI and output a video signal with a Look Up Table (LUT) applied. COLR can work both wired (via Ethernet) and wirelessly, as it has a built in Wi-Fi access point. Once connected you can control the system via a web user interface. This interface allows you to load in LUTs, including 1D LUTs, CDLs, and 3D LUTs with up to 33-point accuracy.

Canon recently released two packages of 3D LUTs for use with Canon Log and Canon Log 2 on the C300 Mark II. The LUTs are being made available by Canon in .cube format, which is suitable for use in Blackmagic Design’s DaVinci Resolve and many other programs. The .zip file packages, in 17x and 33x size cubes, are currently available for download on Canon’s new website. However, to make things easier – especially for Mac users – we’ve taken the liberty of making Canon’s two .zip files available here without modification. Use the links below to download the two LUT packages directly:

In a previous blog, Andy showed us how to create LUTs using Sony’s RAW Viewer software and then import them into the Sony F5 & F55. You can use the same workflow in Sony RAW Viewer to create and import LUTs to the FS7 — but what about when you want to use a LUT that was not created by Sony software?

In this blog, I will create a 3D LUT in DaVinci Resolve and then import it into the FS7. Using the steps outlined in the above video, any .cube LUT can be held in the FS7’s memory. Having the ability to use 3D .cube LUTs expands the capabilities of the camera and allows users to draw on an infinite range of looks for footage recorded in Log or RAW.

One of the great features of the Panasonic VariCam 35 is its built in color management. The camera can record in VariCam Log while applying look up tables (LUTs) to all outputs, including the viewfinder. The camera can load in both 3D LUTs for full color adjustment, as well as CDLs (Color Decision Lists) for basic Lift, Gamma, Gain and Saturation adjustments. While these LUTs and CDL files can be loaded in via an SD card, what really makes this camera unique is that it can also be live graded.

Using Pomfort’s LiveGrade software and a network connection (wireless or wired), the software can directly talk to the camera and adjust colors – no LUT box needed. This feature allows you to make color decisions on the fly, while still recording in high quality Log internally on the camera. All 3D LUTs and CDL adjustments are made live as metadata on each recording. Watch my video above to learn how to set up the camera to enable this function, and stay tuned for the second part on enabling LiveGrade.

There’s been yet another major firmware update to Convergent Design’s Odyssey7 series of external monitors/recorders. This time the focus is on monitoring, routing/distribution and, especially, LUTs (Look Up Tables).

Let’s start with LUTs. Up to 140 custom 3D-LUTs can be loaded into the Odyssey7Q or 7Q+. Cube sizes of 17x, 32x, 33x, 64x and 65x are supported in .cube format (.cube is the input format; a free app from Convergent is available to translate to the Odyssey’s internal LUT format). At this point, LUTs are for viewing only, so it’s not possible to “bake” the LUT into footage recorded by the Odyssey. However, any LUT used while footage is being recorded can be noted in an associated XML for re-application in post. Both extended and legal range LUTs are supported.

The Atomos Shogun has become a top choice for off-camera monitoring and recording. Its lightweight and feature-rich design make it ideal for acquisition from HD up to 4K. In this blog, I take a look at some of the newer features made available through recent firmware updates, including working with LUTs, audio recording, recording HD & 4K simultaneously, and how to record a clean video signal from the Shogun.
