Playing with broken images is one thing but can the Nik Software make otherwise attractive images "better" (for some value of better). In this experiment I'll take an image from a 2013 visit to the Chartres Cathedral, with a working Nikon D3s, and have some fun with Analog Efex and Color Efex.
Firstly the original Lightroom 6 corrected image is
And now the Analog Efex Pro version (Classic Camera 7)
And finally the Color Efex Pro (Soft Landscape, I know it's not a landscape but that's the recipe that I liked)
It's obviously very subjective but I do like the Color Efex Pro version the most.
