ORF, the Olympus Raw Format, is written by every Olympus camera that shoots RAW: the E-system DSLRs, the PEN and OM-D bodies, the Tough compacts, and the OM System cameras that carry the line on. The files are compact for RAW, and like all RAW files they are unreadable to phones, browsers and the people you want to show your pictures to.
This page develops ORF files into JPGs at full resolution, with the white balance the camera set and the orientation it stored. The developer was tested here with files from an E-3 and reads the ORF family as a whole. Brightness, contrast and saturation can be adjusted in the editor before you download.
RAW development is a Pro feature on this site; ORF files up to 200 MB are accepted, 500 at a time. Each file is encrypted in transit, developed on our own servers and deleted within the hour.
What Micro Four Thirds lenses leave to software
The Micro Four Thirds system was designed around software correction from the start. Its lenses are small and light partly because they are allowed to distort: straight lines bow outward at wide angles, and the camera straightens them invisibly in the viewfinder and in its own JPGs. The correction instructions are stored in the ORF, and RAW editors that know the system apply them.
The development here does not. It shows what the lens projected onto the sensor. With the professional zooms and most primes you will hardly notice. With compact kit zooms at their widest setting, buildings lean and horizons curve near the edges, and the frame may show slightly more of the scene than the camera's JPG did. For architecture and interiors, treat these JPGs as proofs and make the finals in a RAW editor.
Picture Modes, Art Filters and High Res Shot
Picture Modes such as Natural, Vivid and Monotone, and the Art Filters, are applied by the camera to its JPGs. They are not part of the sensor data, so the developed picture is neutral and in colour whatever was selected. Raise contrast and saturation in the editor to move toward the Vivid look, or switch on Black and white.
High Res Shot combines several exposures into one large RAW file of 50 megapixels or more, depending on the camera and the mode. Up to 50 megapixels these are developed at full size. Above that, as with the 80-megapixel tripod mode, the picture is developed at half its width and height, and the result carries a warning. Twenty megapixels, the normal size of current bodies, is far below the limit.
Four-thirds proportions and where they fit
ORF pictures have a 4:3 shape, squarer than the 3:2 of most other cameras. That suits tablets, presentations and portrait-orientation prints, and it means a strip is lost wherever a wider shape is wanted: 10 by 15 centimetre prints, 16:9 slides, most website banners.
Decide the cut yourself. The crop tool in the editor offers 16:9 and other fixed ratios, and Resize with the fit on Fill and crop brings a batch to exact dimensions in one pass. A twenty-megapixel ORF develops to a JPG of 6 to 9 MB at the starting quality of 90; for sending, 3000 pixels on the long side and quality 80 give under 1.5 MB.
Frequently asked questions
Which cameras write ORF files?
Olympus E-system DSLRs, PEN and OM-D cameras, some Tough and Stylus compacts, and OM System bodies such as the OM-1 and OM-5.
Why are straight lines curved in my developed JPG?
The lens distorts and relies on software to correct it. The camera's own JPG is corrected; this neutral development is not. A RAW editor with lens profiles straightens them.
Are Art Filters applied?
No. Art Filters and Picture Modes are camera processing for JPGs. The developed picture is neutral.
Is ORF conversion included in the free plan?
No. Developing camera RAW files is part of Pro. Every other conversion on the site is free.
Can I convert High Res Shot files?
Yes. Files of up to 50 megapixels are developed at full size, larger ones at half size with a warning.
How long does a file take?
About a second to develop, plus the upload. A batch of large files is mostly limited by your connection.
