Talk:ORF format

12 bits of what?
"ORF files contain 12 bits, 14 bits or more, while JPEG images have only 8 bits.". 12 bits of what? Shouldn't it read "12 bits of intensity information per channel", or something like that? (I'm no expert, but this seems a bit inaccurate.) --Johs (talk) 14:55, 3 June 2010 (UTC)
 * Not only that, it's also wrong. ORF images are 12 bpp only.  But there's so much wrong in this article that I don't know where to start.  Groogle (talk) 04:16, 1 February 2022 (UTC)

OEF format
Olympus Studio Format (OEF ) is a variant of the Olympus Raw File format that was introduced in Olympus Studio 1.x and that can store additional non-destructive processing information.

Comparison of formats
In Olympus Studio 1.x one can open an image in ORF format using the "Open Image Edit" function and save it back with some non-destructive processing operations added as metadata to the file. Additionally, one can mark some of these operations to be applied during batch processing of the files.

Only information about the following operations can be saved in the ORF format:
 * RAW Development Settings
 * Resize
 * Distortion Correction
 * Shading Compensation
 * Noise Reduction
 * Filter
 * Rotate/Flip

The OEF format can store information about the following additional operations:
 * Tone Curve
 * Brightness & Contrast
 * Gamma Correction
 * Color Balance
 * Sharpness
 * Hue, Saturation & Lightness
 * Insert Text
 * Crop
 * Auto Tone Correction
 * Fisheye Correction

OEF format can be directly opened and edited only by Olympus Studio software. However, if file extensions are renamed from .OEF to .ORF, the files can be opened my most software than can handle the ORF file format proving that the two formats are very similar.

Additionally, OEF format is not supported by Olympus Studio "batch processing" functionality, although it's supported by the "convert format" functionality (that applies all image processing operations functioning as an alternative way to do batch processing).
