Good news, iOS includes basic photo editing features for when you need something quick and easy.
To get started:
Tap the “Photos” app on the homescreen.
Tap on a photo’s thumbnail. ( Thumbnail is a smaller representation of the larger photo. )
Click the “Edit” button. If you do not see it, tap the large photo once and the interface will appear.
That will bring up the edit menu. From there you can, in order shown, rotate, auto color correct, red eye removal, or crop.
In this example, lets tap Crop. ( The icon on the far right. ) That will bring up the crop guides. Drag the corners until you have what you want. You can also press the “Constrain” button and it will constrain the dimensions. Once you are all set, tap the yellow “Crop” button.
Looks good? Now tap the yellow “Save” button and you are set!
The great thing about iOS is that in the above example, after you have saved, you can go back and edit the photo again. It remembers the original state so that any crop is never completely permanent while on the phone.
Ok, so you are a power user and you want more. No worries, the App Store has you covered. I recommend the following:
iPhoto for iOS – created by Apple this gem works on iPhone and iPad. It has gestures, photo beaming, advanced filters and a ton more.
Camera+ – this camera app has been one of my favorites for a long time. You can shoot photos, edit them on a “lightbox”, apply advanced filters, custom crops, borders, etc…
Adobe Photoshop Express – great for a quick crop, photo filters like noise reduction, borders, exposure, saturation and all you need for basic photo editing.
Snapseed – this powerhouse of a little app is perfect for advanced filters, where it really shines, to really give your photos extra something. It has basic editing features too.
