I am not sure how much pixelshift resolution contributes to the colour (in real life), but the amount of details that can be extracted in the post processing is impressive. The style of the painting really benefited from pixelshift. The other painting in this series look a bit boring in comparison.

In course of the last 7 months, I visited Lithuania twice. In October 2016 I stayed in Kaunas for two nights and in May 2017 I was luck enough to visit Kaunas, Jonava, Kernave and Trakai. During my visit last year, I was taken to a museum called Nineth Fort. I though it would be interesting to shoot some static objects there using pixelshift feature.
 - Stained glass.
 - A painting called "Lament of the family"
 - A map of fortifications around Kaunas.
The next images were taken in the old town of Kaunas.
 - House of Perkūnas
 - A. Mapu street. Notice the flare caused by the street lights.
 - J. Gruodžio street. There are some motion artefacts in the leaves, but this is to be expected given the length of exposure.
May 2017. Trakai Island Castle.
 - A painting.
 - Weapons.
 - Some more weapons.
The rest of the shots from that sessions can be found here : 2017-05-13 - Lithuania, Trakai Castle. Pixelshift. | Flickr
Equipment used : Pentax K-3 II and Sigma HSM Art 18-35 F1.8. Click on the preview images to download the full-sized originals from Flickr.
Processing these images was tricky. First of all my main RAW converter DxO 10, does not support Pixelshift. SilkyPix DS Pro 7, does support this feature, but it is nowhere near as good when it comes to correcting lens distortion and perspective. When I tried importing tiff files from SP into DxO, the latter refused to recognise lens used, hence was unable to apply lens specific corrections. I figured out that the tiff files produced by PDCU had the required info and them, and DxO did recognise the lens used. So I developed the same set of images in PDCU, without making any adjustments to them and copied all the metadata from them using EXIFTool GUI into the TIFF files produced by SP. Now DxO was able to find all the necessary information in the metadata to use lens profiles. Voila ! After correcting the perspective and distortion, I used "Smart Lighting" tool to tweak contrast, highlights and shadows, because SP produced somewhat flat looking images.
