Luminance HDR 2.2.1

We are pleased to announce Luminance HDR 2.2.1, a minor release with a few bug fixes.

For all the Windows users, TIFF support is now fully working again. Moreover, we also decided to split the GUI and the CLI into two independent executable: for those who use the CLI often, you have to use the new luminance-hdr-cli executable. This choice has several positive sides: Luminance HDR starts on Windows in a blink of an eye now, while the CLI is finally available on Mac OS X as well.

Just because we had a couple of bug reports in the past weeks, Luminance HDR requires at least SSE2 to work properly.

If you spot any bug, or you want to suggest a new feature, please use our Tracker.

Luminance HDR 2.2.0

We are pleased to announce Luminance HDR 2.2.0.

A long time has passed since the last Luminance HDR (2.1.0), however we did work a lot on it, both on the user interface and on the internal engine. We do have great ideas of how to improve it even more, so we decided to give you the effort of around six months of work while we continue working on it.

If you spot any bug, or you want to suggest a new feature, please our Tracker.

You can download Luminance HDR 2.2.0 using one of these links:

[ Windows (32-bit) setup ][ Windows (32-bit) 7z ]
[ Windows (64-bit) setup ][ Windows (64-bit) 7z ]

Note [Mac Users]: As the previous version, we have phased out support for 32 bit on Mac OS X. At the same time, we phased out support for Mac OS X Leopard as well, so you will need at least Snow Leopard to use Luminance HDR 2.2.0.

Update on the next release

This blog post is a little update on the status of Luminance HDR.

We have been working on a new version of Luminance HDR since the release of the current version, trying to improve functionalities and add a few more, with the aim of giving you a better software. Our core development team now counts a new member (Bruce), that has been a patch supplier for a long time before joining our team. However, we didn’t plan yet when and how the next release will be (maybe christmas?), so it might take long. Be patient!

In the meanwhile, I (Davide) started a new side project: I am trying to make a library out of Luminance’s engine, in order to offer similar functionalities to other software of the open source community. It is a really big project, that will keep me busy for a long period. However, it is my personal commitment to not leave Luminance HDR, which I’ve been cuddling for more than a year and I am proud of!

Mailing Lists

We decided to open 3 new mailing lists with the aim of a closer relationship with users, translators and potential developers. These mailing lists can be found here:

Feel free to join one or more that our mailing list: we are looking forward for you!

Luminance HDR 2.1.0

We are pleased to announce a new version of Luminance HDR. We are changing Luminance HDR deeply, re-factoring a lot of the legacy code. We are trying to add new features and at the same time take out the maximum from new multicore machines using new development techniques. This version is absolutely a big improvement for Windows users, which will experience a more stable and faster software. I do not want to list all the changes we made for this version, it will be too long, but we are definitely waiting for your comments in order to bring out a version 2.1.1 really quickly with all the improvements and the bug fix that Luminance HDR may require.

You can download Luminance 2.1.0 using one of these links:

[ Windows (32-bit) ]
[ Windows (64-bit) ]
[ Mac OS X (64-bit, Intel) ]

Note [Mac Users]: This version of Luminance HDR runs only with Mac OS X 10.6 Snow Leopard and Mac OS X 10.7 Lion, in 64-bit native. We do not think to release a 32-bit version anymore, so Mac OS X 10.5 users should stick to the old version.

Luminance, 64 bits and Macs (Lion?)

I have been working on Mac OS X since I have taken the lead of the Luminance HDR project. Mac OS X is a nice platform, supported well by Qt, with several good quality external tool available (mainly coming from the Linux world). I did a lot of work to shape a nice interface on OS X and I will do more work later on this aspect.
To make my life easier, I decided to release a 32 bit only version of Luminance HDR (both for Windows and Mac OS X). Luminance however can be compiled in 64 bit without any drawback and this has several advantages. And in fact Daniel Kaneider’s work on a Win64 and my experiment with Universal compilation prove that.
So, since I started the development line that will bring to Luminance HDR 2.1.0 (still don’t know when!), I worked with the idea to release 64 bit builds at the end.

But obviously Apple decided that my plan to make an Universal build was too easy. I don’t know how many of you still use a 32 bit machine with OS X, but surely they are still a lot of people that did not upgrade to Snow Leopard from Leopard (and they will probably not upgrade to Lion): so now I am facing my personal dilemma about Luminance HDR’s development. In fact the new XCode 4 supports only OS X 10.6 and later, but not 10.5 (which means cutting out all the Leopard’s users). At the same time, Qt made its move and decided to support officially only 64 bit build, unless you do not compile Qt on your own.

Currently I’m working on Snow Leopard, using Qt 4.7.3 and supporting OS X Leopard (and 32 bit builds), but if I will upgrade my machine to Lion (not sure I will do that anyway), I will be forced to cut off all Leopard users and, as a consequence, drop the 32 bit build (Snow Leopard surely supports 64 bit applications, so it would not make sense to make a 32 bit build).

Luminance HDR on Windows 64

Daniel Kaneider, a long collaborator of the Luminance HDR project (even when the name was Qtpfsgui), made a 64 bit build of Luminance HDR for Windows.
It is a great thing to see Luminance running in 64 bit on Windows, but unfortunately this build is to be considered really unstable. However, we need your help to spread it around a learn when it crashes and why, so we can make it better, more stable and faster.
You can download the build on the link below. We are particularly interested in:

  • crashes
  • UI behaviour
  • visual artifacts
  • memory footprint (hdr creation and tonemapping in particular)
  • RAW handling

Git?

What do you think if Luminance HDR moves to Git?

Luminance HDR 2.0.2

Luminance HDR is growing, improving and leaving behind some of its historic problem: memory hungriness and unexpected faults. I am trying to sort out as many problem I can and, at the same time, I am getting a lot of patches from really smart guys that I will never thank enough. Most of the work in this new version has been made “under the hood”, so you will not see any drastic change in the UI (which is good… and bad!).

Changes [compared with 2.0.1, while some of them were already present in the 2.0.2-pre1]:

  • LibRAW is now in charge to convert RAW files, removing the dependency from dcraw as an external tool (Thanks to Franco Comida)
  • New Batch Tonemapping Engine
  • Smaller memory footprint during the TM process
  • Better acquisition/release of the memory
  • [Windows only] improved responsiveness of the UI
  • [Windows only] update of some of the dependencies
  • [Mac only] Luminance HDR 2.0.2 works on Mac OS X 10.5.X (64 bits version for Snow Leopard also planned, but not yet released)
  • [Mac only] Better UI in Mac OS X (looks cleaner and closer to the Mac style)
  • Huge memory leak during the HDR creation process has been sorted out. The overall procedure is now much faster and uses less memory
  • Huge clean of compilation errors and wrong memory allocation/release (Thanks to Elizabeth Oldham)
  • [Linux only] Multithread support is active again and improved (using OpenMP)
  • [FreeBSD] Cleaner compilation (Thanks to Joao Rocha Braga Filho, Maintainer of Luminance HDR for FreeBSD)

I would also thank a great Luminance’s user, Ron Todd, who made available for all of us his experiments with the new LibRAW engine and blowing highlights (I strongly suggest you to read it!).

My current “To Do” list is too long to fit in here, but while I am releasing this version, I am playing with the Intel TBB library (Threading Building Blocks) and I am probably going to introduce a new dependency in the next version. At the same time, as I am already discussing in a previous blog post, the project will most likely switch to CMake, leaving QMake.
