Reviewed DSC Labs Chroma Du Monde


Visual Impact were provided with a DSC Labs CamAlign CDM 28R Chroma Du Monde to test at their Teddington base this week, and unsurprisingly were impressed with what they found.
Upon first impressions, the test chart seemed to employ a far too reflective surface which would inherently cause unwanted reflections and thus yield incorrect results. A brief set-up under the in house lighting rig proved this to be the case as the results were erratic and somewhat ineffective. After some time spent correcting the lighting environment and fixing the chart with a slight downward tilt (as per the provided help card), we were able to control or eliminate the unwanted reflections and flare to see the dynamic range the camera was capable of capturing. Matte and semi matte charts have long been favoured in the industry due to their non reflective properties, but at the cost of providing a lower contrast. With all the talk in digital cinema being about dynamic range, this is now something that is particularly relevant.
The colours were as expected from a Chroma Du Monde chart, which demonstrates why they are deemed top of the pile. Perfectly rendered due to DSC's surface / ink / dye combinations, the 28 colours surrounding the chart ensured the camera could be checked and adjusted to the HD ITU-R BT.709 colourimetry standard on a vectorscope. Once the chart was positioned and lit correctly, it was clear that it is a fantastic tool for matching cameras, which is something the Visual Impact Engineering Team are regularly asked to do. Whilst not tested on this occasion, the chart if shot by the camera team, should enable post production to eradicate variations in lighting and camera characteristics with precision and speed.
In summary, the chart is a fantastic accessory, it is not cheap and does require a level of set-up time, but once it is, the Chroma Du Monde chart should still be regarded as one of the best field alignment charts available today.

What is next in OTT
Mary Kay Evans In the past year alone, we’ve seen a substantial increase in the amount of OTT content that’s being streamed. In the first quarter of 2018, there’s been a 114 percent year-over-year growth in streaming video hours, and those numbers are only expected to rise. With OTT revenue predicted to reach $16.6B in 2018, a 40% gain over last year, there’s no question that OTT is booming, and that there’s never been a more critical time to pay attention to the space.

IBC in a post Brexit world
Peter Savage 2 Cast your mind forward and we are not in 2018 but next year and, yes, it’s you and me walking to the departure lounge to catch the plane to IBC just as I, and perhaps also you, have done for the last 25 years. (By the way, where is my long service award – and perhaps a new pair of shoes as I must, surely, have walked the equivalent of five Caminos covering the 12 halls in the Rai). We are at the gate and my imagination kicks in as I hypothesize on what the trip might look like next year. I leave it to you to decide which is closest to what might be to come.

Why are trade shows still important
Mike Crimp First, the disclaimer: as the CEO of a rather large trade show, my opinion is likely to be skewed. However, I wouldn’t be here – now in my eighth year at IBC - if I didn’t truly believe that well-curated trade shows like IBC are a hugely important resource for our industry.
