To edit photos on your apple iphone 6 just go into the photos section. From in here click on any photo you with to edit by clicking the top right edit button. There are 3 main editing options. The first one lets you crop, the second lets you choose the color background, and the last one allows you to choose the color balance of your photo. I’m definitely a fan of there photo editor, however I wish they had a bigger selection on the background option.
