Ever wondered if you could use a photo cataloging and editing software for free, without renouncing to powerful features, and across computer platforms? Enter Darktable
Darktable (learn more) is an open source photography workflow application and raw developer. A virtual lighttable and darkroom for photographers. It manages your digital negatives in a database, lets you view them through a zoomable lighttable and enables you to develop raw images and enhance them. It has the features that most Lightroom users need. Darktable is available for Windows, Mac OS X and Linux, and it won’t cost you a penny.
The video below by Anthony Morganti gives you a very good overview. To learn more and to master it, we recommend you follow Rico Richardson feed on YouTube where you’ll find lots of tutorials. You can also have a look at the online manual.
General features of Darktable:
Non-destructive editing throughout the complete workflow, your original images are never modified.
Take advantage of the real power of raw: All darktable core functions operate on 4×32-bit floating point pixel buffers, enabling SSE instructions for speedups.
GPU accelerated image processing: many image operations are lightning fast thanks to OpenCL support (runtime detection and enabling).
Professional color management: darktable is fully color managed, supporting automatic display profile detection on most systems, including built-in ICC profile support for sRGB, Adobe RGB, XYZ and linear RGB color spaces.
Cross platform: darktable runs on Linux, Mac OS X / macports, BSD, Windows and Solaris 11 / GNOME.
Filtering and sorting: search your image collections by tags, image rating (stars), color labels and many more, use flexible database queries on all metadata of your images.
Image formats: darktable can import a variety of standard, raw and high dynamic range image formats (e.g. JPEG, CR2, NEF, HDR, PFM, RAF … ).
Zero-latency, zoomable user interface: through multi-level software caches darktable provides a fluid experience.
Tethered shooting: support for instrumentation of your camera with live view for some camera brands.
Speaks your language: darktable currently comes with 21 translations:Albanian, Catalan, Czech, Danish, Dutch, French, German, Greek, Hebrew, Hungarian, Italian, Japanese, Polish, Portugese (Brazilian and Portugese), Russian, Slovak, Slovenian, Spanish, Swedish, Ukrainian.
Powerful export system supports G+ and Facebook webalbums, flickr upload, disk storage, 1:1 copy, email attachments and can generate a simple html-based web gallery. darktable allows you to export to low dynamic range (JPEG, PNG, TIFF), 16-bit (PPM, TIFF), or linear high dynamic range (PFM, EXR) images.
Never lose your image development settings darktable uses both XMPsidecar files as well as its fast database for saving metadata and processing settings. All Exif data is read and written using libexiv2.
Automate repetitive tasks: Many aspects of darktable can be scripted in Lua.
Robin Wong had a closer look at telecentric lens design, and explains that:
[…] telecentric lens design [means] having the optics designed in a way that the light will hit the sensor more linearly without too much straying off, and this was already adopted by Four Thirds system lens mount in 2003
This technical approach was used by Olympus 16 years ago, when they introduced the Olympus DSLR E-1.
And Canon and Nikon?
Both Nikon and Canon took the advantage to introduce new mount. Nikon made 2 changes: 1) increase the lens mount throat diameter opening from 47mm to 55mm and 2) reduce the flange back focal distance from 46.5mm to 16mm. Similarly, Canon, maintaining their already large lens mount opening of 54mm (just 1mm shy of Nikon’s new Z mount opening), decreased their flange back focal distance from 44mm to 20mm […][…] having larger glass element to fully envelope the image sensor area allows light to hit the sensor more perpendicularly, and bringing the rear end glass element from the lens closer to the image sensor minimizes light strays and bending. The obvious benefits in terms of technical image quality? Minimized aberrations (chromatic, spherical, etc), improved corner./edge sharpness, and better per pixel optimized light capture overall.
Sound complicated? The video below tells you everything about telecentric lens design in 9 minutes.
ePHOTOzine compared the new Canon PowerShot G5 X Mark II to its predecessor, the PowerShot G5 X.
From their verdict:
The Canon Powershot G5X Mark II offers a number of improvements, including high-speed continuous shooting (up to 30fps), 4K video recording, and updated white balance options, as well as an extended ISO range. There’s also a new design, that makes the camera lighter, and slightly more compact. However, if you don’t need 4K video recording, and want a flash hot-shoe, then the original G5X offers a fairly compelling package, particularly as it’s price is quite competitive.
If you need (or want) 4K video recording, then the G5 X Mark II is the one to go for out of these two cameras, and the additional zoom range of the new 5x optical zoom lens is welcome. The new 5x optical zoom lens certainly impresses, delivering sharp, detailed photos across the zoom range. If video is your primary aim, then the G7X Mark III, could be worth a look as it adds in a microphone socket.
