Evoto can identify females, males, kids, and seniors in a photo and apply effects separately. By switching the Female, Male, kid, and Senior tabs and moving sliders, you can adjust the amount of effects being added. ## For photos with multiple faces, how to select a face? Evoto hasn't launched the Face Selection function yet. But we have a trick that can be used to do face selection for pictures with four or fewer faces: * Click Gender & Age modify button. * Set the age and gender of the people in the picture to be different; for example, if there are two ladies in a photo, Evoto AI would mark them Female. To edit them separately, you should change the mark, like one is Female, the other is Kid. * Click Save. * Switching the Age & Gender tab to adjust effects. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://help.evoto.ai/product-tour/how-to-use-evoto/face-recognition.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
