Normally when you try to edit you're picture in whole on instagram, it doesn't let you!
Let's begin! :D The first step is to download the free app, Montage Lite.
When you open the app, it'll lead you to this page. Tap the + sign in the top left corner to get started!
Once you select your photo, it'll take you to this screen. Here you have the option of Color, B&W, or Sepia. Once you've decided, hit "Add".
Here you edit your picture to about the same scale as the image shown above. This is to ensure perfection later on. Once satisfied, tap "Save"! 😊
I highly suggest saving the image as a Double. The picture is crisp and clear this way. Once selected, tap "Render".
One you're led to this screen, tap "Save" again and "Save to Photo Library".
Now you're ready to open Instagram and it's photo editor! Use the latest photo added to your photo library to begin edit. 😊
See how the entire photo fits within the crop box now? 😄 Also, the extra white will simply blend into the Instagram background later on.
Edit the photo as you please.....
And complete! Comment for feedback and questions! 😃 Thanks!
