first_imgDating of artifacts and fossils may become much more common thanks to a new instrument.Without doubt, radiocarbon dating has been an exciting and contentious process. It has been able to resolve disputes about the construction date of archaeological sites, such as Hezekiah’s Tunnel in Jerusalem (9/10/03). Creationists find radiocarbon all over in places it shouldn’t be (see Real Science Radio’s list), such as coal and diamonds; evolutionists cry “contamination!” (Note: all radiocarbon should vanish from a sample before 100,000 years). Resolving disputes has been costly and time-consuming. Typically, the best results come from labs with equipment for accelerator mass spectroscopy (AMS), but only 100 or so labs worldwide have the equipment.What would happen if you could get radiocarbon dates almost as accurate as AMS at one tenth the cost, within two hours? This may become common, if the encouraging announcement from Italy’s Istituto Nazionale di Ottica lives up to its promises. Science Daily says,The instrument, which uses a new approach called saturated-absorption cavity ring-down (SCAR), is described in The Optical Society’s journal for high impact research, Optica. SCAR offers significant time and cost savings compared to the standard approach for carbon dating and could be useful for a host of other applications such as measuring emissions from fossil fuels or certifying the amount of biogenic content in biofuels.The equipment, which works on a laser cavity principle, is smaller, faster, and cheaper. It costs a tenth of AMS. It might even become portable. Each test, furthermore, is half the cost of AMS, the article says:The researchers report that their SCAR instrument can detect radiocarbon dioxide concentration with a precision of 0.4 percent, which approaches the 0.2 percent precision of the best accelerator mass spectrometers. The new technique can deliver results in just two hours, with each test costing about half what it would if conducted using an accelerator mass spectrometer.The researchers estimate the SCAR instrument is about 100 times smaller and 10 times cheaper than the instrumentation required for accelerator mass spectrometry. Its size and cost could decrease even more once the instrument is converted from its current tabletop version to a more portable commercial prototype.The designers envision archaeologists being able to test artifacts in the field. “This could revolutionize the approach that archaeologists use for carbon dating because they would not have to send sensitive samples away to a lab and wait weeks for a result,” one of the team members said.We hope radiocarbon dates will become much easier to obtain, so that creation researchers can test samples of coal, diamond and dinosaur bone quickly and cheaply. This technique, if it fulfills the promises, could make possible multiple tests on the same sample by different labs or teams, reducing the credibility of charges about contamination. Many more samples could be dated. There should be zero radiocarbon in samples older than 100,000 years. Enough undisputed radiocarbon-positive results on “old” samples could completely undermine the evolutionary timeline. Let’s get the data!

first_imgCheck out these great tips on how to make the most of your Blackmagic Design Cinema Camera’s RAW files inside DaVinci Resolve and FCPX.Creating One-Light Dailies from BMDCC DNG RAW files in ResolveIf you’re trying to get your Blackmagic Design Cinema Camera RAW files into an editable format the free DaVinci Resolve Lite software (as well as the full version of Resolve you received when you bought the camera) will help you quickly make that happen. In this straight forward tutorial, Dan Kanes walks through how to correctly set the color space for your DNG RAW files and transcode them to Pro Res quicktime files in DaVinci Resolve 9.1. Dan also demonstrates how to adjust your white balance and exposure adjustments in your RAW files and make global changes to all your footage to create one light dailies.Blackmagic Film to Video Plugin for FCPXAdam Roberts is a London based DP who has been sharing his progress with the BMDCC and on his blog.  He has some great tutorials and camera tests (previously shared on Premiumbeat here) which are well worth a watch if you’re looking into getting a BMDCC or trying to get started with the one you’ve just bought/hired. In this post Adam has been beta testing a Final Cut Pro X plugin created by Nick Shaw from Antler Post Production which allows you to apply the Film Log to Rec. 709 LUT (similar to what Dan Kanes does above) but without leaving the FCPX timeline.BMD Cinema Camera – Movie Making MachineDirector of Photography Shane Hurlburt has been preparing to shoot the upcoming feature Need for Speed and has posted this lengthy report on how he’s tested the BMDCC’s RAW capabilities to see if it could be the main camera for the shoot. If you’re hungry for technically detailed soaked camera tests then this is for you. Shane covers everything from sensor sizes, bit depth, filters, cages, eye-piece adaptors, lenses and more. Its a great example of what else is required to turn the basic BMDCC body into a feature filmmaking machine.last_img read more
