Baker Street Pixel Shift

I've been wanting to try out the pixel shift technology on my a7riii since I got it. Pixel shifted images have a couple of requirements. They have to be perfectly still with nothing moving in the shot and the camera must not move so will need to be on a tripod, this saves on complicated re aligning in post. I think the software may be able to cope with this but I didn't want to risk it.

With this in mind I could think of no better subject than Baker Street tube station. It fits the bill perfectly with the only complication being people on the platform and trains coming in and out.

From what I understand what pixel shift will take 4 images, shifting the sensor 1 pixel for each image. This leads to the camera capturing all the RGB information for each pixel and a final images that is (4*42) megapixels in size, so 168 megapixels.

To create this image you have to take your 4 images from the camera and combine them using Sonys Imaging Edge software. This will then output an ARQ file, mine was 325mb in size and the individual images about 81.8mb, so you get roughly all the data from each image in one large file. Photoshop is not able to read the ARQ file so I converted it to a TIF with Sonys software and then imported it for editing.

The end image has a lot more detail than the single file, the colour also looks a lot more realistic and required less editing. I'm not sure the level of detail matters that much unless you are printing the image really really large. That said,  I do like the end product and it wasn't too difficult to work with. I assigned my c1 button to pixel shift so its really easy to setup in camera.

This is a feature that I will definitely use again, especially for architectural shots.

Here are the results:

 This is the finished product, I'm quite pleased with it, I wanted to shoot a really wide pano but the station was quite busy and it would have take a lot of time to get it exactly how I wanted it. So I'll save that one for another day, one that isn't over a bank holiday weekend.  This is an incredibly detailed image, you cant quite read the writing on the tube map zoomed in though.

 This is a 300% crop from the image to show you the difference in sharpness, this is the normal image without pixel shifting straight from the camera.

 This is a similar 300% crop from the shifted image, as you can see there is a lot more detail and the colour is much better.
