I'm sorry to break it to you, but your photos kinda suck. The people look all dark and blue and dull…. It's not your fault, but you can do a simple thing to make them WAY BETTER. Let me show you.
See this picture I took of a frog? How adorable. He's so cute. But the picture is really... meh.
Easy fix. I’m looking at it in my photos app, so I tap edit in the upper right, and from the bottom slides in some easy-to-use controls. I tap the magic wand and slide it from side to side to see how I like it best and boom! Instant results.
Now, you can go further. No other app needed, you can poke through these sliders and change the brightness, contrast, saturation, warmth, etc. but even just the magic wand makes it look better. When you're showing off a photo of your family, doing this can make it a photo that they see and say "that's ok" to a photo that they say "I love this! You must have an amazing camera!"
The thing is, you do! The iPhone is probably the best camera you've ever owned. It’s one of the best cameras ever made. They've got some amazing tech, and you get to use it whenever you want. Take joy in that, take pride in it, take and share GOOD photos! :)
