Rawker is a freeware converter program for RAW files produced by digital photo cameras. It's philosophy is the good old Apple motto: "Keep it simple". It allows you to convert a single RAW file or batch process a folder of RAW files. It is also possible to specify a hot folder that Rawker scans every few seconds. When new files show up in the hot folder, Rawker automatically converts them.
Before processing any files you can modify settings that may optimize the appearance of your image(s). These settings can be saved in a file and re-loaded later.

It allows you to convert a single RAW file or batch process a folder of RAW files. It is also possible to specify a hot folder that Rawker scans every few seconds.

Before processing any files you can modify settings that may optimize the appearance of your image(s). These settings can be saved in a file and re-loaded later.
During batch processing Rawker shows the image it is currently working on. Rawker produces TIFF image files with 16 bits color depth (which is 48 bits per RGB pixel) or PNG (16 bits) or JPEG (8 bits) files.
Metadata present in the RAW files will be preserved when exporting as TIFF and JPEG output files.
Rawker converts RAW files using one of two modes: It can convert RAW files using Apple's Core Graphics (Quartz) technology, or it can use Dave Coffin's DCRaw tool. You choose which mode Rawker will use for RAW file conversion. DCRaw doesn't need to be installed separately, it's embedded into Rawker.

Because blown highlights can often retain detail in one channel, it'd be useful to be able to see an RGB histogram, rather than just the luminosity-based histogram currently provided by Rawker.
Also, numeric scales on a few sliders, esp. Gamma, would be helpful.
On the whole, Rawker is useful, but not useful enough to replace any of the RAW converters I currently use (ACR, Lightroom, or Capture One).

Also, current Rawker versions should run faster than the first releases.
Bye, Rainer.

Why must we transform a RAW to something like TIFF for manipulate the pic? That's the way the company of the camera code a picture in RAW! So Canon RAW isn't the same as Nikon RAW. Thats the problem for a converter. It must convert the different RAWs into something like a TIFF. More you can read is here: http://ronbigelow.com/articles/raw/raw.htm and here: http://ronbigelow.com/articles/raw2/raw2.htm

You shoot in RAW to capture more details, and hopefully make your image look better when you HAVE to convert it to sRGB for display online.
The poster is quite correct that shooting in high-depth and processing at 16 bit doesn't make much sense if you're going to re-compress the colors back down to 8-bit sRGB and end up with the same image.
Generally though, that's not the case.
There's another, more subtle point. If you put a pro behind a raw converter, the pro may be able to set up the raw converter to extract the optimal range of data to put into the sRGB file. Making it possible for the pro to make better use of sRGB than shooting in JPEG. So there is a purpose to all this.
Everybody using (and understanding) color management should definitely uncheck sRGB conversion and assign a color space with a large gamut (in Photoshop or similar app).

sRGB is a narrow color space perfect for ensuring the best results when uploading images to the web. I use it as a webdesigner.
AdobeRGB is wider, and supported by most cameras. Though, ProPhoto is a better, wider choice.
Anyway, why shoot in RAW when ending up downgrading the image, somehow, for example converting it to JPEG, sRGB? Simple:
Raw gives the opportunity to tweak and color grade and correct overexposure and underexposure, then creating a TIFF or JPEG. Had you just shot the image as JPEG in the first place, all those color and exposure corrections would look horrible.
sRGB is a wrong choice if you plan to print your image, but it's an ok choice to convert to that profile if you put your images on the web.
That's why there are different profiles: They are meant to fit their individual purposes. You can't just say: "ProPhoto is king - use it always" - that would be missing the point entirely.
