Optimise Your Optics

All lenses produce vignetting and distortion to some degree, and this hasn’t yet been accounted for. Click on the ‘Lens Corrections’ tab and tick the two boxes to automatically fix any optical defects. Because you’ve used the same aperture value and focal length for all the shots that make up the HDR image, the corrections will be the same, so you can apply them to the HDR. If your particular lens isn’t found automatically when you tick ‘Enable Profile Correction’, select the ‘Make’ and ‘Model’ of your lens from the dropdown lists and the changes will be applied.
