G'MIC is very easy to use! You don't need any experience to apply some cool effects to your photos. Simply select a photo, run G'MIC and apply an effect. That's all!
To use G'MIC once installed, open a photo in GIMP and go to Filters > G'MIC and a dialog will pop-up where you can select the effect you want to apply. Each effect is of course customizable and you can see a live preview in the G'MIC window.
