rawson.js is just 500kb in size, while desktop raw processors require you to download dozens of megabytes
rawson.js is the perfect choice for opening raw files on guest computers. It doesn't force you to store or convert files locally, and its traces can be quickly removed by clearing the browser cache.
Enjoy the rawson.js on every platform, without prior installation. rawson.js runs in Firefox 3.6+ or Chrome 8+ on Windows, Linux or MacOS X
Opening a RAW file takes about 5 seconds on my moderately equiped Lenovo ThinkPad Edge 13 laptop (AMD K685, 6GB RAM)In v0.2 the performance is poor on purpose, as we wanted to access real raw data. v0.3 should bring a smarter rendering mechanism again.
The rawson.js viewer application will not run on current versions of Internet Explorer (IE 9 or less), because IE doesn't support the W3C File API for local file access. This might change in IE 10.
Not yet. We 've introduced the rendering of real raw image data in v0.2, but there still is a long way to go to support editing.
The camera reviews of Photography Blog and Imaging Resource usually include a few RAW images for each camera model. Rawsamples.ch provides a collection of older RAW images, but hasn't been updated since 2009. RAW images are quite big (30 MB and more), so please do not hot-link these files.
Use a faster laptop/computer. Since v0.2, we are rendering the actual raw image data, not just the embedded preview. On netbooks/slower laptops it might take minutes until a raw image is opened. We are working on a mechanism to optimize the rendering of raw images for slower systems.
Make sure you have closed/deactivated Firebug or the Chrome Developer Extensions. Especially Firebug can massively slow down rawson.js
Cross your fingers and try another raw file ;)
"Rawson" isn't just a cool-sounding word starting with "RAW...", it is in fact the capital of the Argentine province Chubut, Patagonia. Before starting to work on my then undubbed RAW previewer, I travelled to Argentina and explored the beauty of Patagonia. During the travel, I also noticed certain tensions between Argentina and England. So I decided to name my project "rawson.js" in order to remind the two countries of their shared past (The city of Rawson was founded by Welsh immigrants in 1854)The logo animal of rawson.js is a Commerson's Dolphin (Cephalorhynchus commersonii), whose very distinctive patterning might remind one of the Bayer filters used in Digital photography.
The following table shows all Camera RAW file types, that are (theoretically) supported by rawson.js. Because the RAW decoding component of rawson is a direct port of dcraw.c, it inherits all functionality from it.
