No Camera FX does not allow for a file to be saved in the RAW format. No app that I've seen offers any other file format than jpeg that & I've looked at a LOT of photo imaging apps. I think that would have to be done via the Camera Sensor software at the Android OS level at the time of capture & before the jpeg was created to pass on the info to any other app. I can't imagine RAW is desireable by the Mfg. to include due to the file size increase for the average person & the raw software processing power required for user processing in camera. I'd imagine that today's phones are only & barely acquiring enough cpu resources to consider processing raw files. I'd prefer to have that option too but someone is going to have to hack in to figure it out.
Best you can do is to fiddle with your stock camera app settings & to turn off or to dial down any sharpening, & to increase the resolution to the max, try to use manual ISO control & keep it as low as possible & keep any saturation or exposure or contrast adjustments to a minimum to prevent too much in camera jpeg processing. I use an HTC DHD & have figured out what settings work best for the least in camera processing & output quality. But I do fiddle with them to on an individual image basis.
Camera FX only allows for different jpeg quality levels of compression, much like the stock camera app. It's a nice app otherwise. Wait for it to go on sale. I picked it up for 10 cents during the sale a couple of weeks ago. You can likely do without until then.
Maybe future generations of smartphones will allow Raw capture saving as these phones are quickly replacing P&S cameras, at least for me. But few P&S cameras offer Raw saving until you get into the more expensive models, even though I believe that all devices initially capture in a raw code but instantly process the raw data into the jpeg format. So RAW saving can likely be done but it may need better cpu use for the user processing software after capture?
