Maybe I did, or maybe not, but my reply was about your crop/screenshots of the DPR review tool, not the crops of your own processing of the RAW files.
What I was saying is that those JPEGs of the DPR tool look completely different than when I go directly to the corresponding DPR review tool URL for the same cameras and ISO.
They looked different both in terms of colors and amount of detail. Unfortunately, Pentaxforums very highly compresses any files uploaded. I have some Pixelshift files from my K-1 II which are nearly 200MB. I can generate a 3MB JPG from them. And then PF compresses them to 180KB ... That makes PF uploads pretty useless for purposes of image comparison, unfortunately

NICE FIND!!! They changed the k-1 Mk II images!!! Check also the file sizes!!!

Wow . Seems like DPR has an egg on its face. Maybe it was them who cooked the RAW files, and not Pentax ? But actually, only the JPEG file size changed, not the RAW file size. Yet "RAW" was selected. So I wonder why the image looks different if file size did not change.
Do you still have the copy of the previous RAW file, and can you compare it with the current one ?

DNG are the same then there was a problem with JPEG conversion of the RAW.

So why did your 2 screenshots look so different, since you had selected RAW in both ?

Because what you see in the DPR comparison tool, that is a web tool, isn't the real RAW but a JPEG developed directly from the RAW.

Sure, but if the RAWs haven't changed, the developed JPEGs that the tool shows when you click "RAW" shouldn't change either.
Unless they have changed not just the OOC JPEG files, but the output of the processing of unchanged RAW files.

the raws have changed I just downloaded the new one and the old one had camera raw process version 6.7, the new one version 10.

When you click RAW you are not watching the JPEG inside the RAW but a JPEG that they have processed.

Changing [~~RAWs~~ RAW-linked, and separately displayed]* jpegs without attribution is beyond dishonest. It is active sabotage. At this point they should take down the entire article, confess, and start over.

*edited for accuracy. It is now beyond confusing what they’re doing.

Yes, I get that. So, to recap :
1) DPR changed the files from OOC JPEGs . Your screenshots clearly show this - file sizes of JPEGs have changed.
2) DPR left the RAW files alone for download Your screenshots show RAW file size is unchanged.
3) DPR have changed the JPEGs that are shown when you click "RAW" in their comparison tool . Ie. they have reprocessed the RAW files to JPEG

No RAW change, they changed the processed JPEG from RAW. Adding the different and defective lens I'm with you about "At this point they should take down the entire article, confess, and start over.".

They nullify Pentax's standard raw adjustments in lightroom and apply their own WB and exposure compensation. First pic is wat DPReview shows us, second is what is loaded into lightroom by default with noise and sharpness adjustments:

That is quite weird, if DNG has process version tag it means it was processed and saved again as DNG. OOC DNG RAW EXIF from K-1 does not have any process version -tags. I can take a TIFF anytime and add postprocessing to the file and save it again as DNG if I want. What a mess.

Andrea K · 05-11-2018, 04:48 AM

I have to add that they shot also with D-Range highlights correction at ON. This affected also the RAW.

Here 12800 ISO:

That in DPR comparison tool is:

Where the k-1 MkII absolutely shines is in the DPR Low Light test.... I can't explain why so much difference between the two scenes:

at:
Image comparison: Digital Photography Review

This with RAW comparison... If you select JPEG the result is reversed again...

The copper coin does have more detail but much of the bill has less detail in the new K-1 sample. Are these samples from the original DPR ..sample image or are they samples from the K-1 II image recently posted by DPR.
