RawSpeed moves to github

As you may have noticed, there hasn’t been much activity lately, since all on the Rawstudio team has had various things getting in the way of doing more work on Rawstudio.

I have however now and again found time to work on RawSpeed, and will from now on host all changes on github. Github makes a lot of work much easier, and allows direct pull requests to be made.

RawSpeed Version 2; New Cameras & Features

The new features that has been included and can be tested on the development branch. Note that this is RawSpeed and not Rawstudio.

Support for Sigma foveon cameras.
Support for Fuji cameras.
Support old Minolta, Panasonic, Sony and other cameras (contributed by Pedro Côrte-Real)
Arbitrary CFA definition sizes.
Use pugixml for xml parsing to avoid depending on libxml.

When “version 2” is stabilized a bit, a formal relase will be made, whereafter the API will be locked.

Enfuse support in Rawstudio

I’ve been working on Enfuse support in Rawstudio for quite a while and now it’s ready for some testing :D

It was added to trunk yesterday and packages are ready in our Launchpad PPA for Ubuntu.

A quick guide:

Select photo(s) and press ctrl-alt-e (or find Enfuse in Photo menu).
Adjust settings and update thumbnail by clicking on it .
When you are happy with the thumbnail, click “Execute” and wait for the finished result to be opened.

Some notes:

You might have noticed that I’ve written “photo(s)” in the first step above – you can select just one photo and Rawstudio will help you export different exposures from that photo and you might get a better result than the initial photo (or not).
To get as high a quality as possible, Rawstudio exports photos in 16bit PNG and Enfuse hands it back to Rawstudio as 16bit PNG. Even though the files are PNG, the extension are “rse” (RawStudio Enfuse) to make the files easy to identify.
Be patient! I’ve done a lot to speed the process up as much as possible, but exporting, aligning and enfusing full size photos does take time!
Photos that have been enfused might need some extra work as you are used to with RAW :)

Well, go ahead and give it a try – I’d like to get some comments on it (here or at http://bugzilla.rawstudio.org/)

I’ve made a few screen captures of it in use. This is the speed I have on my relatively slow laptop. Check them out below…

RawSpeed Development Information Posted

I have written up some information on the RawSpeed decoder, and how it can be implemented.

Here are links to the articles.

If you have any additional areas you’d like to have covered, or have any questions, just leave a comment, and I will try to address it.

Rawstudio 2.1 Feature Freeze

We have been slowly updating Rawstudio despite an otherwise busy schedule. This Here is a quick run-through of the new features.

Asynchronous Display Rendering

One of the most common requests is a more responsive UI, when adjusting settings. I didn’t expect this to be a huge win, since it will not actually speed up rendering. However, after an experimental implementation, it really makes a big difference in how responsive the program feels.

Basically all adjustments are now pushed to a separate thread, that begins re-rendering the image, if no further adjustments are made for 50 milliseconds. This makes sliders much more responsive, since an instant re-render isn’t triggered right away.

Since multi-threading in a complex application such as Rawstudio can bring some unforeseen consequences, this is also the most likely source of instability. Not in the sense of data loss, but it could still result in some unexpected and hard to reproduce crashes.

System Display Profile

You can now use the display profiles you have assigned to your monitors. You can select the to use the system display profile in the Preferences box:

New “Advanced” profiles

We have created a number of “Advanced” color profiles, which will hopefully give a more precise color reproduction than the “simple” matrix-based profiles. You can read more about them here in a previous blog entry.

Rawstudio Advanced Profiles Available

We have been so lucky to find a source for profile images, and made profiles for 93 different cameras. The advanced profiles are more detailed than a simple matrix operation, which is the base of the “simple” profiles that are already present. This should hopefully give more faithful color reproductions for most cases.

Here is a shot of Adobes DNG Profile editor in which the profiles were created:

Advanced profiles are available for the following cameras:

Avoid using Quick Export in Rawstudio 2.0

A bug has been discovered in Rawstudio 2.0, that disables de-noise when using the “Quick Export” feature. Ordinary “Save As…” and Batch processing is not affected by this bug.

Technically the de-noising is automatically adjusted based on the scaling performed of the image. Due to the order in which the size is set (or rather isn’t set), the de-noising filter thinks the image is scaled to 0%, which completely disables de-noising.

Luckily the next version is right around the corner, and the current development version is quite stable. And since Anders has fixed the daily Ubuntu build system, you can grab a version there, or do the build yourself from SVN if you have that type of skills.

Sorry for the inconvenience.

What’s up in the Future for Rawstudio?

There are of course still areas where we could improve Rawstudio – as unlikely as that may seem :)

Here are some of the things I have noted for upcoming major things that come to mind. If you have any input on any of the topics or new suggestions, we are very interested in hearing your opinion in the comments below.

Cool image from sxc.hu with reference to the future :)

Here we go – here is a braindump of the issues that are top-of-mind right now:

Rawstudio! What is it good for?

After some quiet time after the 2.0 here is a small video from the release party we held right after 2.0 shipped:

Hope you enjoyed the video. You can download the music which was made for the occasion by two of our good friends. I had a bit of fun afterwards and threw together a remix, with a bit more of a “party” feeling.

We all needed a short break after 2.0, but now we will begin looking into what the future brings!

Excellent Article on Linux.com

Linux.com has published a very well written and researched article by Nathan Willis, called Editing RAW Photos on Linux with Rawstudio 2.0. It is a very good introduction to all the features of the 2.0 release, and what they will mean to you. Be sure to check it out!

When your exported images does not always look like the preview

When you work with digital images, it important that they look the same way. Therefore it can be very frustrating when they look differently in different applications.

First I want to make sure you understand the concept of colorspaces. I will not go into details about the technicalities, since there are a lot of great resources on the topic on the internet [1], [2]. We are only dealing with RGB colorspaces, so you can disregard talk about CMYK, Lab, YCrCb and other colorspaces.

In overall terms a color profile determines how an RGB value in the image is displayed on the screen. In general colorspaces are handled in different ways in different image formats, but it is very common that an ICC profile is embedded in the image, that tells how the image data should be interpreted.

Maintaining correct colors can be quite a puzzle (sorry for the bad pun)
