The customization options on Lenka let you do many things, such as switch the camera to video format (by pinching the screen) or change the contrast of the filter. In fact, you'll find two sliders that you can move as you wish, which will control the black and white filter that gets applied to the camera.
Inside the app you'll find an image gallery with very simple editing tools so you can crop your pictures or rotate them as desired. Once you've made all the changes, you can export any of the images to Instagram or other apps.
Lenka is a camera app that's both simple and elegant. Even though it doesn't have lots of features, it still offers very good results.
