![]() It is really interesting what they managed over the years.Īnyway not to digress too much, the basic RAW file is indeed supported, even this “hack-y” one because it is esentially still the same old. Heck, even 550D’s you can get on ebay for about 100$ have about 13 stops of DR and shoot 14bit RAW with c-log and many other things with this firmware. Its not a very user friendly or “polished” feature per-se, but pulls a lot more out of your 2008 camera. It can then be recovered by running it through the aformentioned program (cr2hdr) into something normal looking. The image is encoded normally by the camera and is fully supported by PR3. Otherwise you might as well just bracket a few exposures and stitch in post for an even greater DR improvement. It just forces the camera’s ADC registers to sample each alternate line in a different ISO value, so its still a regular single image capture, the benefits being you require no tripod, no exact framing for several consecutive frames etc, just shoot normally. I see, this is a bit of a different thing and more of a “firmware hack” if you will. The only post-processing PureRAW/PhotoLab will tolerate is conversion from native RAW to native DNG and that only if done with Adobe DNG Converter (which is also built into Lightroom). If the basic RAW file is not supported, there may be tricks you can use (principally faking the metadata to represent a supported device) to force them to open, but any special treatment, whether in-camera or after the fact, will generally render it un-openable. PureRAW and PhotoLab read that single dump from supported cameras and lenses. The key thing to understand is the basic concept of a RAW file is a dump of the sensor data once. I would assume “Dual-ISO” is a multi-frame capture where each frame is at a different ISO. In the case of my Pentax Pixel Shift, there is a completely different matrix in the file as it combines four captures into a single fully-RGB matrix. You mentioned your camera’s “Dual-ISO feature” which I take to mean there is more information in the file than just a single captured frame. I should clarify my point about the “single Bayer/Foveon matrix”. I do not have any compression or anything else enabled, comparibility profile is Camera raw 14.0ĭoes anyone know any hacks how to take a normal (but PR3 unsupported) DNG and convert it into supported DNG? ![]() But i assumed that if i then exported these DNGs into DNG using lightroom, lightroom would apply its “correct” encoding and then it would work, but it doesnt seem to be the case. These DNG files are read fine and edited fine in all apps i have on my computer, but not Pure Raw (and i didnt expect it because it is stated). Now a bit about these files, they are from 5D2 shot using Dual-ISO feature that gives about 2.5-3 stops more of dynamic range, but requires processing in the form of conversion with a tool “cr2hdr” to create completed DNG files. I am using PureRAW 3 in my workflow, trying to import DNG files that were exported via Lightroom or via the Adobe DNG converter (i tried both), but in the app it only shows a full white square, and after export it is a full white square.
