It’s a pity that you apparently have only .raw and .jpg files on your machine.
My RawTherapee opens many other kinds of raw files, for example .RW2 from my Panasonic G1 or G9 but as you say not .raw from my LX1. It even opens Foveon .X3F files but not perfectly.
The general solution is to convert odd raw formats with the camera’s proprietary converter and to export them as 16-bit ProPhoto TIFFs to your editor of choice
Do you know the raw file type for the Panasonic Lumix “DMC-LX1”?
ChatGPT:
The Panasonic Lumix DMC-LX1 uses the “.RAW” file extension for its raw image files. This is one of the instances where Panasonic used the “.RAW” extension directly, which is less common compared to their later models that typically use “.RW2”.
Me:
Thanks. Is the “.RAW” an early raw file extension - perhaps no longer popular?
ChatGPT
Yes, that’s correct. The “.RAW” file extension was used by some early digital cameras, including models from Panasonic like the Lumix DMC-LX1. This usage was before more standardized and unique RAW file extensions became common. Over time, manufacturers developed their own proprietary RAW formats with distinct file extensions to better support the specific features and capabilities of their camera models. For example, Panasonic later shifted to using “.RW2” for their RAW files.
The move to unique file extensions such as “.NEF” for Nikon, “.CR2” for Canon, and “.ARW” for Sony helps in optimizing compatibility with photo editing software and enhances file management systems specific to each brand’s processing needs. The “.RAW” extension is relatively rare today and is not commonly used by newer camera models.
Have you confirmed the appropriate filename extensions are enabled (or even added) in Preferences | File Browser | Parsed Extensions? Even if a file format is supported, it won’t be displayed in the browser unless it’s enabled in this list.
I’m pretty sure I’ve seen raw audio with no metadata. I think one of the Raspberry Pi camera utilities saves raw image data with no metadata and names the file .raw
As others have pointed out, unless a “.RAW” file has a metadata header in a known/recognizable/detectable format (such as some Panasonic cameras), RawTherapee doesn’t have enough information to do anything with it - it doesn’t know the bit depth, endianness, black point or white point, appropriate color transformation, color filter array pattern, or even the image width/height.
PNG parsing is disabled by default, it has been for so long that whatever the reason why is lost to history.
@yeahman: Please post one of your .raw files, and tell us whatever you can about the file: did it come from a digital camera? If so, what make/model camera? Or did it come from some other software?
@xpatUSA: Yes. I suspect (but I don’t know) that @yeahman’s .raw files are not “raw” files from a camera. Until we can examine a file, we can only guess.
Thanks to everyone for correcting my partial mistake: I have learned that the .raw extension is used for some camera raw files.
I simply stated that many years ago (decades before mass market digital cameras) there was indeed a “raw” image format (*.raw) that wasn’t a digital camera raw file as we know them now. I never said nor implied that any other “raw” files couldn’t be from from cameras. I commented solely on that old format.
