Whether Motion Correction is turned on or off RawTherapee produces an almost identical outstanding output for the two raw files. In addition to these color shifts there are also weird patterns in the water. It seems to me that Lightroom handles the files in the same manner. With Pixel Shift activated I shot one image with Motion Correction off and one with MC turned on. The scene is shot both with and without Pixel Shift. The final example image has some light wave action going on (ripples). It is not unlikely that less blurry edges would have made things easier for the motion correction algorithm like seen in the waterfall example where well defined edges resulted in a perfect outcome with no color fringing. ![]() RawTherapee yields a much cleaner result, but some minor color fringing remains around the branches.Ī faster shutter speed would have preserved more details in the branches – solely my mistake. As seen in the following close crop (4:1) Lightroom introduces this weird checkerboard pattern: The image is edited in RawTherapee 5.1.Įven though it was very quiet there was some movement in the foliage. There was almost no wind when I shot the following image an afternoon in January. The difference is striking – I don’t think any further comments are necessary the images speak for themselves. A fantastic shot by Chris – well balanced with a great comp and sharpness all across.įirst we will check out how Lightroom handles the motion in the foliage and water:Īnd this is how RawTherapee translates the file: The image is raw prepped in RawTherapee and edited in Photoshop. A waterfall, depending on its size and power, will always cause some movement in the foliage closest to it. The Gorge is located along the Columbia River just outside of Portland Oregon. ![]() The first image is a waterfall image shot by Chris Williams – the image is used with permission. We will also show how the Pixel Shift functionality is activated in RawTherapee. I do not have access to other raw converters. We will in the following have a close look at several images shot with the Pentax K-1 set to Pixel Shift and compare how RawTherapee and Lightroom handle the files. However, the people involved in the Open Source project RawTherapee, which is an advanced raw converter, have now come up with a solution in version 5.1 of the program. Even when Motion Correction is activated in camera these unwanted effects occur. The major downside with Pentax’ Pixel Shift technology has been issues and artifacts produced when we have a scene with motion.
