News from the World of Tomorrow

And more awesome updates!

Some awesome updates from the community and activity over on the forums! People have been busy doing some really neat things (that really never fail to astound me). The level of expertise we have floating around on so many topics is quite inspiring.

darktable 2.0 Release Candidate

Towards a Better darktable!

A nice Halloween weekend gift for the F/OSS photo community from darktable: a first Release Candidate for a 2.0 release is now available!

Houz made the announcement on the forums this past weekend and includes some caveats. (Edits will be preserved going up, but it won’t be possible to downgrade back to 1.6.x).

Preliminary notes from houz (and Github):

  • darktable has been ported to gtk-3.0
  • new thumbnail cache replaces mipmap cache (much improved speed, less crashiness)
  • added print mode
  • reworked screen color management (softproof, gamut check etc.)
  • text watermarks
  • color reconstruction module
  • raw black/white point module
  • delete/trash feature
  • addition to shadows&highlights
  • more proper Kelvin temperature, fine-tuning preset interpolation in WB iop
  • noiseprofiles are in external JSON file now
  • monochrome raw demosaicing (not sure whether it will stay for release, like Deflicker, but hopefully it will stay)
  • aspect ratios for crop&rotate can be added to conf (ae36f03)
  • navigating lighttable with arrow keys and space/enter
  • pdf export – some changes might happen there still
  • brush size/hardness/opacity have key accels
  • the facebook login procedure is a little different now
  • export can upscale
  • we no longer drop history entries above the selected one when leaving dr or switching images
  • text/font/color in watermarks
  • image information now supports gps altitude
  • allow adding tone- and basecurve nodes with ctrl-click
  • we renamed mipmaps to thumbnails in the preferences
  • new “mode” parameter in the export panel
  • high quality export now downsamples before watermark and frame to guarantee consistent results
  • lua scripts can now add UI elements to the lighttable view (buttons, sliders etc…)
  • a new repository for external lua scripts was started.

G’MIC 1.6.7

Because apparently David Tschumperlé doesn’t sleep, a new release of G’MIC was recently announced as well! This release includes a really neat new patch-based texture resynthesizer that David has been playing with for a while now.

![G'MIC Syntexturize Patch|960x661](upload://vXbiCpZp2bi47ufzApahfRzOs9g.jpeg)
Re-synthesizing an input texture to an output of arbitrary size.

It will build an output texture of arbitrary size based on an input texture (and can result in some neat looking peppers apparently).

Speaking of G’MIC…

G’MIC for Adobe After Effects and Premier Pro

Yes, I know it’s Adobe. Still, I can’t help but think that this might be an awesome way to introduce some people to the amazing work being done by so many F/OSS creators.

Tobias Fleischer announced on this post that he has managed to get G’MIC working with After Effects and Premier Pro. Even some of the more intensive filters like skeleton and Rodilius appear to be working fine (if a bit sluggish)!

You might remember PhotoFlow as the project that creator Andrea Ferrero used when writing his Blended Panorama Tutorial from a few months ago. What you might not realize is that Andrea has also been working at a furious pace improving PhotoFlow (indeed it feels like every few days he is announcing new improvements - almost as fast as G’MIC!).

Example of PhotoFlow perspective correction.

His latest release was announced a few days ago as 0.2.3. He’s incorporated some nice new improvements in this version:

  • the additon of the LMMSE demosaicing method, directly derived from the algorithm implemented in RawTherapee
  • an impulse noise (also known as salt&pepper) reduction tool, again derived from rawTherapee. It effectively reduces isolated bright and dark pixels.
  • a perspective correction tool, derived from Darktable. It can simultaneously correct horizontal and vertical perspective as well as tilting, and works interactively.

Head on over to the PhotoFlow Blog to check things out!

LightZone 4.1.3 Released

We don’t hear as often from folks using LightZone, but that doesn’t mean they’re not working on things! In fact, Doug Pardee just stopped by the forums a while ago to announce a new release is available, 4.1.3. (Bonus fun - read that topic to see the Revised BSD License go flying right over my head!)

Head over to [their announcement] to see what they’re up to. [their announcement]:

Rapid Photo Downloader

We also had the developer of Rapid Photo Downloader, Damon Lynch, stop by the forums to solicit feedback from users just the other day. A nice discussion ensued and is well worth reading (or even contributing to!).

Damon is working hard on the next release of RPD (apparently the biggest update since the projects inception in 2007!), so go show some support and provide some feedback for him.

RawTherapee Forum

![RawTherapee Logo](upload://meXGE58B4aGW62FOcYwZ842FPHh.png)

The RawTherapee team is testing out having a forum over here on discuss as well (we welcomed the G’MIC community a little while ago). This is currently an alternate forum for the project (which may become the official forum in the future). The category is quiet as we only just set it up, so drop by and say hello!

I want to thank Morgan Hardwood ( for providing us a wonderful view of Röstånga, Sweden as a background image on the main page.

Do you know what’s needed for the next big thing in Digital Darkroom software?

It’s the integration of multi-image sampling in the development workflow, to maximize the SNR, dynamic range and increase the bit-depth limit of an image, i.e. median or mean sampling of several similar/identical frames to attain higher SNR and to get higher bit-depth images, We could also integrate the ZeroNoise technique.

This is similar to merging an HDR separately to get a 32bit TIFF file and opening that file in a compatible Digital Darkroom software, but what I’m suggesting here is integration.

Perhaps something similar to a wizard (sorry I’m a bit old-fashioned) asking you to start with a single image or averaging stack with identical exposure settings (with or without alignment), or with two (or more) images with different exposures to execute the ZeroNoise technique or HDR merging (not toning).

I’m very certain that the first one to implement this in the Open Source Community will very quickly gain a huge chunk of the market-share.

Have you had a chance to look at HDRMerge? I believe it’s pretty much everything you’re asking for… :smile:

@Morgan_Hardwood has had some experience using it as well, I believe.

The (abandoned) command line version of Filmulator has this feature, but it was very cumbersome to point at all the files in a bracket sequence. And it has no alignment capability, so it only works for tripod work. Additionally, that’s even less integrated because it only does the filmulation step, not any other post processing work.

Eventually once I figure out a good user interface and a good way to represent it in the database I will re-add the feature into the GUI version, but I haven’t figured that out yet.

I’ve created a small bash script that works in combination with the command-line version of PhotoFlow, initially with the idea of automating a superresolution technique described in this same forum (see this post and the link to the script).

However, the same can I think be used to increase the SNR by combining several similar images, if no up-scaling is performed. It could be combined with 32-bit floating point TIFF output for best results.

The script works on RAW input images, and calls align_image_stack to align handheld shots prior to the averaging step.

darktable has the ability to merge several images into one HDR for ages. It doesn’t align but it works on bayer raw files so you still can tune everything afterwards, including demosaicing.
