The first screen of Reallusion FaceFilter Studio invites you to open an image for further editing. In the left side there is a handy toolbar that allows you to prepare the image with rotation, scaling, zooming and color adjustment instruments 

This is the first step window where you are asked to Fit the Facial Mask. You may follow the step-by-step autofitting guide and preview the Smile and Sad expression results 

The Enhance Skin window displays a skin tones toolbox from which you can select the skin color, the brush size and opacity. You can also add eye color and skin filters here 

In the Filter skin panel you can see a Before and After compared preview. Here you can select some skin templates or you can adjust by your own the smooth level and the intensity and fuzziness of the shadow and gloss 

The next step guides you to select a facial expression. As well, you can select one from the templates or you can create your own expression through the manual adjustment mode 

You can see here how the Proportion and Width can be manually adjusted. After finalizing the desired expression of the face you will need to press the Keep the Result button in order to save the modified image 

The final step leads you to the printing process, where you can finally preview the modified facial expression integrated into the original image that you have first opened
