The retro kit includes 9 presets that apply a collection of effects and tweaks to create a unique feel to your photos. The base presets can be used to make old stock film style color modifications, and the retro presets will create retro looking photos. These filters took me a very long time to get the effect and feel that I want,  whilst still maintaining the original colors and emotion of the photo. They do not effect the  exposure of the picture. You will have the best results if you manipulate the exposure, highlights, and white levels post application of the filter.
