I’ve searched for years for the right presets and/or plugins that would assist me in my post-processing. The past few months I’ve been using VSCO film presets. I have become absolutely in love with these and have almost completely quit using all other plugins/presets. I think what makes them unique is that they use the adjustments within lightroom and therefore you don’t have to create multiple picture files and you can always make post-preset adjustments at any time. It allows me to spend more time taking pictures and less time post-processing. Also, many of the presets fit my style of photography perfectly.
VSCO Film is sold under 4 sets, modern, classic, instant, and slide film. I probably use classic, instant, and slide film the most. I will forewarn, they are expensive but you do get a discount for each set you buy after purchasing one. Personally, I think they are well worth it.
Here is a post by Steve Huff with samples (he got me hooked on them).
Below are a few pictures of before and after (click on the images to see them larger). Let me know if you have any questions.
