As we know the new A7riii has a pixel shift function, it takes 4 images moving the sensor around each time. When merged with special software it creates a large and very detailed image with huge dynamic range and great colour. Sony do however point out the limitations of this approach. If things move in the scene it won't really work so you need the camera on a tripod and have nothing move in the scene.
I thought I would put this to the test, as the images created when using pixel shift are awesome. Is the image totally destroyed by the movement or would it be usable?
While In Bruges for my birthday I decided to try this at night. below is the resulting image from the merged 4 pixel shifted images.
So this is what happens if things move in your image, you get these strange artefacts. Im not sure what this would mean for cloud movement in the sky, it would probably create a massive mess. This would however work in certain circumstances with minimal movement and you could alway edit out the artefacts in post, colour matching may be difficult but not impossible.
I won't use this in the majority of my shots but it does have its place and it was fun finding out.
