This is a pretty cool development from LibRaw (the company behind FastRawViewer) which lets you squeeze an extra stop of dynamic range out of your Canon 5D Mark IV raw files. Essentially, it exploits a quirk of dual pixel raw files. As they explain, a dual pixel raw file is essentially two exposures in one, a stop apart. Their new app, DPRSplit uses these two exposures to form a new DNG raw file containing the dynamic range of both exposures.
Adobe to add 5D Mark IV’s dual pixel RAW functionality to Lightroom and Photoshop
The dual pixel sensor of the 5D Mark IV has two main functions. One is to improve the accuracy of the autofocus. The other gives you slight focus adjustment capabilities in post – a bit like Lytro. The latter is called dual pixel raw. At the moment (well, for those who already have a 5D Mark IV), the dual pixel raw feature is only available to users of Canon’s own software; Digital Photo Professional.
However, Cnet are reporting that Adobe have confirmed they’re adding the 5D Mark IV’s dual pixel raw technology into Lightroom. Presumably, this also includes Adobe Camera Raw. Adobe’s spokesman, Roman Skuratovskiy said “We’re working on it”, but did not specify when this update might be available.
After months of speculation the Canon EOS 5D Mark IV is finally here with 4K video and dual pixel RAW
So, the guesswork and speculation can end. Canon have now officially announced the 5D Mark IV DSLR. As expected, some photographers are a little underwhelmed, if the comments I’m seeing on Facebook are anything to go by. The video guys seem happy, though, mostly.
But it does have a few fairly significant upgrades for stills photographers. The new 30.4MP CMOS sensor is one, sure it’s not the 50MP of the 5DS, but it’s still a nice jump over the Mark III’s 22.3MP. Dual pixel RAW files are another great feature, albeit at the cost of storage space. This works on a similar principle as Lytro, allowing you to slightly adjust your focus in post. But let’s have a look at the full specs.
