I’m a long-time user of Nik Tools, and the suite of filters and presets has been advancing rapidly since DXO took the software over in 2017. There are tools to create a variety of monochrome looks, perspective corrections, sharpening, HDR renders, analog and film replication effects, color adjustments, noise reduction, and sharpening. Now, DXO is offering version 4.3 with 35 new presets, most useful to landscape photographers.
