Chapter 20. Working with Photo Filters

In this chapter, we focus on creating photos for a restaurant and how to use the camera and camera roll. We give the user the ability to take a picture and apply a filter to that picture. In the next chapter, we tie the last chapter and this chapter all together by completing the work on the review form and enabling users to save their reviews. We will also learn how to save photos as well.

In this chapter, you will learn:

  • How to use the camera roll to get pictures
  • How to use the camera to take pictures and bring them into our app
  • How to apply filters to our pictures and get them ready to save to the device
