I can get a little extra in DxO PhotoLab too. #Dxo photolab 2 vs capture one proI also have an Olympus M.Zuiko 12-40mm f/2.8 Pro lens which offers about 20% extra image area at its wideangle setting in Capture One and without distortion. I can squeeze a little extra image area out of wideangle shots, but the corners quickly darken in a way that vignetting corrections can’t fix. I have a Sony E 18-135mm f/3.5-5.6 which is a great lens but leans very heavily on its digital corrections. Generally, I’ve found that this extra crop area is revealed only with cameras that embed correction data directly in the RAW files – typically mirrorless cameras and high-end compacts – and you can only recover extra image area at or near the lens’s shortest focal length. It’s pretty obvious that while I can steal a little extra undistorted height from the image, and just a little from the edges, the distortion quickly takes hold and renders the outer edges unusuable. Unfortunately, in this instance the extra areas are heavily distorted – it’s an indication of the extreme design used by Panasonic for this lens, and the extreme corrections it’s using to produce undistorted images across this zoom range. This is very interesting! It turns out that the camera has actually captured a much wider angle of view than it displays. They might be distorted and unusable, but I won’t know until I manually extend the crop boundaries. Sure enough, if I swap to the Crop tool, I can see in the main Viewer window that there are large areas of image outside the default crop area. It actually shows a far wider image cropped to a central portion (Capture One always displays cropped areas in its thumbnails). If you take a look over at the thumbnail browser on the far right, however, you’ll see that the thumbnail looks far from normal. It looks undistorted and perfectly normal. This is a RAW image opened in Capture One. Most RAW processors respect this embedded crop, as does Capture One, but where Capture One differs is that it will also display the image area outside the crop. These have an embedded crop that excluded distorted areas outside the corrected image area. This extended zoom range is made possible by the camera’s digital lens corrections, which are embedded not just in its JPEGs but in its RAW files too. It was shot on a Panasonic TZ200, a camera with a 1-inch sensor that has a 3:2 native aspect ratio and a 15x optical zoom. The image in this example shows this taken to the extreme. Can Capture One see more than your camera shows you?.I’ve seen DxO PhotoLab do this to a degree, but the program that shows this most graphically is Capture One. #Dxo photolab 2 vs capture one softwareAll processors will respect the image crop embedded in the photo by the camera, but sometimes the software will be able to show the wider image area still present in the RAW file. It depends on your RAW processing software. This extra image area has been captured by the camera’s lens and sensor but discarded by the firmware as being outside of the design parameters of the lens and camera’s digital corrections… or simply doesn’t fit the camera’s native aspect ratio. Where the camera is applying digital lens corrections, there may be more ‘image’ outside the regular image area that you wouldn’t normally see. You might assume your RAW processing software shows you everything captured by the camera, but that’s not always the case.
