SR2 to PDF
Make a one-page PDF from a Sony SR2 capture for comments or a report. The image is developed to 8-bit sRGB, so exposure changes require the SR2 original.

Format Overview & Applications
A review packet can carry a view of an older Sony capture; the SR2 still matters for any later exposure or white-balance revision.
Technical Specifications & Codec Breakdown
LibRaw performs the raw decode with AHD demosaicing, camera white balance and matrix, upright orientation, and an 8-bit sRGB output buffer before the PDF page is built.
OS & Browser Compatibility
A compatible Sony raw application is needed to revisit exposure and white balance; a PDF reader is enough to review the converted photograph in a document.
Useful info
Use the original SR2 to make exposure changes before conversion, since the PDF contains the developed 8-bit rendition rather than camera sensor samples.
Format Comparison & Technical Specifications
A 4288×2848 Sony SR2 image maps to a 28.6×19 inch review page at 150 dpi.
Frequently Asked Questions
Why can’t I change white balance from the PDF?
White balance has already been applied by LibRaw using its camera-white-balance setting; the page contains pixels, not raw controls.
Does the converter rotate camera-held images?
LibRaw’s automatic orientation option is enabled, so the image is placed upright according to the source orientation.
Where should I make another exposure version?
Return to the SR2 in a raw editor; the PDF has no exposure control.
