Sony stated that the DSC-R1 was a real 14-bit digital camera. Quote: "14-Bit DXP A/D Conversion: Sony's 14-bit Digital EXtended Processor captures the range between highlight and shadow with up to 16,384 values, for extended dynamic contrast and detail." The fact that it has 20Mb RAW files prove that it really contains that much information.‬ That’s interesting… Sony stated that the DSC-R1 was a real 14-bit digital camera.

If I am on auto exposure with the M8, it is usually set at -1/3rd to -2/3rd as well…..but that is not really the issue here. Actually it is very much the issue here, one must understand how the DNG compresses the data then uses LUT’s to pad the data back out on decode. There is absolutely no headroom in highlights or the right 1/3rd of the histogram. Here a description to help you understand the limitations of the format (8bit squared) Leica has left us with.

Thanks for the very clear and well written article. Best regards, Benoit Laplante‬ Dear Sir,

If the M8 has a software processor, isn’t possible that they give us the option in the future by a new software release to choose the bit depth?

Thanks for the very clear and well written article.

Best regards,

I confirmed all these explanatios by studying 16-bit developed Leica M8 DNG linear histograms. The explanation of why holes appear in the high lights is clear looking at them. On the other side those 8 bit achieve almost the same detail in the shadow's as Canon's 12 bits.
