Surprisingly, a large number of photographers who use Adobe Lightroom ignore a feature called Split Toning panel. When it comes to a situation where a large number of mixed lighting (for instance, a concert), you may have to find a good neutralizer and Split Toning panel is such good solution.
No matter how complex the existing lighting is, you can create really nice vintage filter effects on your images by following a couple of steps;
Set the highlights to one color at an end of the spectrum
Set shadows to another color
Change the saturation values of each to an equal value
Just adjust the balance and that’s it!
After playing according to these steps for a couple of times, you will be able to bring up effects that are similar to the rendered images from instant films.
If you need a much different appearance, you may consider inverting the hue value to the highlights and shadows. The, you should change the balance skewed toward the shadows values. The end result will be pretty much similar to a soft contrast film.
