How to display pixel shift images.

Hi all. I just bought a K3ii and took an image with pixel shift on and the same image with it off. When zoomed in, I can't detect a difference when I view them in Lightroom. I'm using Lightroom version 6.2.1 and shooting in dng format. I can see that the pixel shift image is huger (1250mg) and the non-shift is normal size (28mg).


What am I doing wrong?

What were the subjects of the photo? Increased detail from the higher resolution of PixelShift is best for landscapes rather than still-life for example. I have seen samples of the later and agree that there's little difference, but samples of the former are very easy to see the increased detail.

When you view a pixel shifted dng file in Lightroom I think you just see the first image saved.

You may need to update camera raw. Once updated, you'll probably also want to increase the sharpness slider to get the raw sharpness up to the same quality as an out-of camera pixel shifted JPEG.

If all else fails, use the supplied Pentax software. It's better than Adobe's in some ways. See:

My subject was my canvas briefcase at close range, approx. 5 feet. The camera was dead still sitting on my desk. Maybe I should try a landscape shot tomorrow.


Rondec, I was understanding that my version of LR was capable of showing the full high-res pixel shift image. Anyone else know for sure?

Thanks, Adam. Do I need Camera Raw if I am only using Lightroom?

Probably. Support for pixel shifted files is very minimal at the moment. (and note that even when you open the file in a program that supports pixel shifted files, the resolution stays at 24 megapixels. You'll just get more detail, less noise and more accurate colors)

Make in-camera TIFF from both images and then do the comparison. LR support for pixel shift is only found in the newest version of ACR.

ACR is a built-in component of Lightroom*. The most recent version should include the updated ACR.

* The develop module in Lightroom is essentially ACR.

It is possible. I don't own Lightroom 6 or a K3 II, I just recalled people complaining about Lightroom's support of the RAW pixel shifted files at one point.

Thanks for all the helpful responses. I will try again today with a variety of subjects and file formats (jpd, tiff, dng). Looking forward to understanding this feature.
