Panasonic GH4 RAW vs. JPEG High ISO Comparison


I’m still in the middle of my ongoing review of the new Panasonic GH4 and wanted to share a few files of the same scene shot across the ISO range.


Here’s a quick look at the in-camera JPEG file processing vs. the GH4 RAW files converted to DNGs and processed through Lightroom 5 with no adjustments. First, here’s a look at the full scene that was captured.

Next, is a chart that looks at the full resolution of the files.

On the left, you’ll see a 100% crop of the images that came as JPEG files straight from the camera. On the right, you’ll see the corresponding RAW files shot alongside the JPEG files in a RAW + JPEG configuration.

[UPDATE: I have added both the RAW files and the converted DNG files for those who want to examine the originals in your own raw processing program. You can download the original files at this link. Please do not post the download link directly to any forums or other sites. It’s ok to link to this page, but if the external bandwidth gets heavy, I will have to take them down.]

I’ll have some additional comparisons soon and full review is in the works as well.

    Hi Eric,

    Thanks for preparing the samples, I’ve had the GH4 for some weeks now, and been playing around with it and comparing it with the GH3 and GX7 but in a non-technical way, and I still believe the GX7 is still much better in the still. I can’t confirm 100% yet, as I am waiting for Adobe to update’s RAW profile for LR, but so far, that’s my opinion and test is coming from DxO Optic’s conversion.
