Happy Holidays to everyone from Lydia, myself and our amazing staff at Hurlbut Visuals. You are so special to us and we cannot thank you enough for all of your commitment and loyalty over 2014. We have had many exciting changes to the look and functionality of the blog. We are always trying to up our game. I am never comfortable with great; we have to aspire to be the best and I push my Web, Social and Production staff to do exactly the same.
With Christmas shopping in full flurry, we are doing back to back tests. Last week, we delivered the Canon EOS C100 MK II tests. Now we are providing the Blackmagic’s URSA so that you can see what new paint brushes you might want to add to your creative tool box.
At first glance, the camera looks like many of its competitors, like the Sony F55 or AJA Cion. It is built to look like an ENG camera and posed to enable the documentary market that is thirsting for 4K content. The tests below quickly show you what this camera can and cannot do. Is it a low light shooter? No, but not everything is about shooting in low light scenarios. There are other cameras that do that in spades. Is it a noisy camera? Yes. Let’s take a look at what the URSA does do well.

Why I Do Tests
Tests are everything in finding your camera’s soul. What it does well and where she breaks. You know how specific I am with tests and this is what you pay for. These tests take a team of over ten collaborators who give of their services to educate all of you.

They cost a good amount of money to do them right. It takes time, attention to detail and accurate notes that I can pass onto all of you. This test was so much fun because I brought back most of my amazing crew from the Illumination Experience tour to do it. My mission is to turn these guys into great additions to the movie business labor pool. I drive them and push them to be excellent.
OK, here we GO!!!!
Test No. 1 – Looking at IR Pollution
The first test that I always do with a new camera is to verify how good its Optical Low Pass Filter (OLPF) is. The BMCC and the BMPC exhibit strong IR pollution after two stops of ND and the URSA reacted the same way. If you are shooting with this camera during the day time and you use Neutral Density so you are not shooting all your imagery at an F11, then you have to follow this test closely because you will have conditions with normal Neutral Density filters that will bake in an IR polluted look that you will not be able to remove.

With WW ND 0.6, NON-IR
I feel you are safe up to two stops of ND, so a WW ND 0.6. After this, you really need to start to use IR NDs to combat all this IR pollution. It affects the skin and green trees first and then drifts into turning your sky purple. We thought it was an awesome look for 1970s found footage. Looked perfect. Putting that into my cinematic memory bank.

Bringing It Back with IR Filtration
We wanted to show you how using an IR filter can help your color grading and assist in not baking the IR polluted look into your footage. We used WW IR NDs from Tiffen for this test and I feel they reacted very well with this sensor.

I felt the Tiffen 2.1 IR ND did not have enough IR embedded into its glass. The 1.5 and 1.8 did a great job counteracting the IR pollution, but the 2.1 did not cut it. Her skin is a weird tone and the background feels like it has this sandy baked in feel.

Test No. 2 – Let’s break the camera!!
This is the most time consuming test. Not many people do the latitude test, but it is the most informative. Finding the sweet spot of your sensor is not done with latitude charts or that the latitude light machine that you see so many tests use. Our work is for you to use in the field, on location or in a studio with extreme conditions.
We are going to start with over-exposing the sensor to push it to its breaking point. What I noticed with this particular 4K sensor was that it doesn’t exhibit the latitude of the BMCC or the BMPCC. I found a useable latitude of about eleven stops. It blows fast, but it has a beautiful roll off into the highlights. I think this is one of the strong points of the camera, so even though it is limited by its latitude, the way it over-exposes feels more like the Arri Alexa. The Canon C300 or C500 clip very fast. It might have 12 stops, but if it looks like video clipping highlights, then what is the point?
I set the exposure on this camera at 18% grey on the False Color chart at 40-45 IRE. Any higher than this, then the camera over exposed very fast. Her skin tones were at 50-60 IRE. Let’s start at the base exposure. My light meter, the Sekonic L-478 DR, reacted perfectly to this camera at 400 ISO.

Up to +1, I feel I could use this intense feeling of light on her face and bring the grade down to hold all detail on her face, still very pleasing. Let’s look at her skin tones especially with this test. This is where the Blackmagic delivers beautiful 12 BIT skin tones that have wonderful depth and dimension. Love it!!!!!

Now let’s examine how well this camera rolls off its highlights. With +2 over exposed on the 18% grey card, her skin is right at 100 IRE on the False Color scale, but what I find beautiful about this camera is how her skin doesn’t exhibit that clippy video feel. It is very smooth. I look at this camera and say I love the skin and I could shoot this easily in white cyc situations. You could expose your wall nicely at +2 over and then your subject around +1/2 and rock it out.

Look how the BMCC cares and exposes beautifully even on +2 ½ stops.You can bring it back and it looks awesome.

Test No. 3 – Let’s Dive into Under-Exposure
What I learned from this test is that it doesn’t exhibit the same underexposing qualities of the BMCC or BMPCC. It falls apart faster. But what I did discover that you could do with this camera is use its ability to handle some underexposure to combat the noise level that you get in low light situations when you slide the ISO up to 800. You will soon see this in our day exterior noise and night exterior noise tests. This camera is very noisy at 800 ISO; it is borderline at 400 ISO. So what I propose to do is to shoot night exterior or interior, low light work at 400 ISO, and then use the ability of Davinci Resolve 11 and the sensor’s under-exposing power to bring the image back up to what looks good without the added noise of taxing the sensor at 800 ISO.
The camera handled -1 stops under exposed very well and retained all detail.

Even -1 ½ stops would work but at -2 stops, she really started to lose BIT depth and became very smoky. Bringing the image back just creates this very weird heightened contrast, which looks forced.

Blackmagic URSA 4K Under -1 ½ Graded
The C500 did not handle underexposing very well either in our Need for Speed tests. After -1 ½ stops it fell apart as well, but you could bring back the BMCC pretty well, again exhibiting the increased latitude of that sensor which boasts 13 stops. I was recently shooting with the Alexa and I love how that camera rolls off highlights and how it handles underexposure, which has 14 stops of latitude. These extra stops are huge for making your image shine. You might not have the resources or a crew to constantly be altering the extreme conditions with nets, neutral density on windows, flying large diffusion frames to take values down. But we are looking at price points, right? The Alexa is $70K and the BMCC is $2K and the URSA is $5K. You have to be realistic with your expectations of a camera at its price point. Period.

In this test with the URSA we took our under-exposure all the way down to -5 stops, but unfortunately for us the SanDisk C-Fast Cards we used did not hold up. One of them corrupted on us and we lost our footage past -2 ½ stops. Due to the time we were running into, we could not go back and reshoot that part of the latitude test.
Stay tuned for Part 2 in the New Year, where we will take the URSA through its paces and show you the camera’s noise levels during the day and night — fill ratio, slow motion and rolling shutter. Happy Holidays and a glorious NEW YEAR!!!!
