1. Click on a photo
2. At the bottom, you'll see five little icons. Click the one with the three horizontal lines.
3. Six icons will appear at the bottom. Click the one that says "Adjust." More icons pop up.
4. Click the one that looks like a magic wand.
5. You'll see a little change in your photo. Maybe a bit lighter; maybe a bit sharper colors; maybe a bit more detail. If you like it, click the icon at the top that says "Done." If you want to go back to the original, click the icon at the top that says "Cancel" and discard the changes. You'll go back to your original photo.
This is an easy way to let the camera do its own photoprocessing without getting too involved. After you do it a few times, it gets easy. See if this does anything you like.
When you click the icon with the three horizontal lines, you'll also see a button that says "Crop." Click "Crop" and you'll see a square icon at the top that lets you rotate the photo if you want.
When you click the icon with the three horizontal lines, you'll also see a button that says "Clean up." This lets you remove unwanted objects. You can enlarge the photo with your fingers, outline the object you want to remove, and click the "Clean up' button. The camera figures out what the background would look like without the object and fills it in for you, with varying degrees of distortion or non-distortion. I go for breakfast at a little local San Mateo airport, which has a restaurant right on the landing field. I took shots of the field with the planes on it, from my table. The fence had a trash can right in the middle of the photo. I was able to remove the trash can and make the picture look better. Sometimes it works; sometimes the "fill in" is a bit distorted. You can always discard the changes and go back to the original if you want. But it's actually pretty clever and functional.
