![]() ![]() ![]() If we do the same with the DNG version "SAMPLE-PENTAX.DNG", we can see that Aftershot did not correctly identify the lens. Here, we can see that Aftershot correctly identified the lens as "smc PENTAX-DA 18-135mm f/3.5-5.6 ED AL DC WR" Now, we open the PEF image "SAMPLE-PENTAX.PEF" and go to the "Lens Correction" tab. We can now navigate to the downloaded PEF and DNG files inside the "File System" tab. In the second dialog, click "Try Corel AfterShot Pro 3". However, the bug is still there even when running as root. You can also run Afterhost with super-user privileges as suggested by the Corel technical support. # now, we download the sample DNG and PEF files to demonstrate the bug # additional requirements for Aftershot (doesn't work without it) # installing Aftershot (including dependencies) CorelDRAW is a powerful software for post processing DNG files. DNG files are native to some Digital Cameras (Leica and Hasselblad). DNG files are smaller than most other raw file formats. The image data is uncompressed and kept in a lossless state. # we use gdebi tool to install deb files including all dependencies DNG file contains every bit of details captured by a digital cameras sensor. Using vagrant, we setup a fresh linux environment - the latest Ubuntu 16.04 Xenial as follows: Vagrant installed (tested with vagrant 1.9.1).VirtualBox installed (tested with VirtualBox 5.1). ![]() Realted GIST describing the problem in detail: Prerequisites (inside the host machine) downloading sample DNG and PEF files from the same camera.To make the setup reproducible, we use vagrant + virtualbox. We are going to demonstrate the bug in a fresh linux box based on the latest Ubuntu 16.04 (Xenial) running inside a virtual machine. This only happens with DNG files and not with other raw formats (e.g PEF, ARW, CR2. With swap enabled, the whole OS slows down tremendously. Both of these devices support Apple ProRAW (as of iOS 16.0.3). If swap is disabled, the application crashes. On a machine with 32 GB RAM, the memory is exhausted after approx. UPDATE (): It seems that Aftershot Pro 3 and 2 contain another bug causing severe memory leaks when generating previews for imported DNG files. There's loads of others too, best to try downloading some demos and see what you like.Reproducible example showing a bug within Corel Aftershot Pro 3 when working with DNG files For a complete deal, the Adobe Lightroom Photography plan is hard to beat - yeah it's $/mth, but look at what you get, three full heavy weight apps, cloud syncing, and regular updates and good support. If you want to spend a little, it maybe depends on whether you want a DAM or just an editor. They all have steep learning curves, but can give excellent results once you learn some basics, and they all get updated frequently, and add new cameras quickly. The freely available Open Source solutions are excellent choices if you're looking for low cost - have a look at darktable, RawTherapee and Digikam or GIMP (if you don't need a DAM). Even Photos is worth a go, although beware if you have a large library, it can fall over a lot if pushed too hard. There are plenty of others things that are much better now. I assume you mean DNG, you can convert to that, sometimes it might work, but not always, and not all of the Raw processing data get's converted well - I had a Fuji that converted, but still left very bad lens distortion uncorrected. It was OK back then, but far from the best, probably good value then (I did get mine in a bundle deal), but now it's pretty much useless, IMHO. I bought Aftershot Pro 3 a couple of years ago, and it's been updated very little since - only two minor updates in over 18 months if I recall, and they didn't include new camera support. That's not necessarily a good reason to use it.
