Some new Pentax Cameras have a parameter "Diffraction Correction". For example Pentax K-S1 and K-3.
When doing a get all parameters with exiftool -a -u -g1 _IMG0046.DNG > out.txt I get as output:

Problems:
1. In this output the "Diffraction Correction" is missing.
2. The parameter "Vignetting Correction" seems to stand for Pentax term "Peripheral Illumin. Correction"
3. The Parameter "Bleach Bypass Toning" has no correspondance in Pentax.
It would be nice to have this parameters (enhancement request). Please tell me if you need the original image.
Thanks for this report.
It is very difficult for ExifTool to be consistent when the manufacturers are always changing things. I am pretty sure that what Pentax once called "Vignetting" is now called "Peripheral Illumination".
About the "Bleach Bypass Toning". It may not be something you can change on the K-3, but the camera writes this tag (which was decoded for the K-5), so ExifTool reports it.
So the only thing I can do something about is the "Diffraction Correction". I can decode this if you could send me 5 sequential images, all shot at the same settings (small JPEG), with only the diffraction correction changed in this sequence: off, on, on, on, off

I got the samples, thanks. ExifTool 9.98 will extract the DiffractionCorrection.
Also, you have convinced me to rename VignettingCorrection to PeripheralIlluminationCorr.
