(With both distortion correction and Topaz Adjust HDR filtration)
After watching a video on "Exposing to the Right" by Peter Forsgard, I decided to change the settings in my camera to match his and test them on this Olympus 17mm f/1.8 lens which has never been a favorite. This images from these settings in this and the next two images have been converted from RAW with DxO Photolab, and brought into Photoshop, where the leaning sides have been corrected and subjects filtered with Topaz Adjust HDR filtration and then sharpened. The Topaz filtration increases the contrast and saturation. This is Peter's video: https://youtu.be/H2h2F4juJAc
