I have mentioned Camera+ before as one of my favourite camera apps for the iPhone.
It is a very powerful photography app and it allows you to use the iPhone camera in ways which the standard camera app doesn’t even come close.
Plenty of ways to share the images too.
They’ve just upgraded the app to version 2.3 which allows you to add captions when you add a border to your image.
Quite a nice subtle feature, though the caption “fits” with the border you choose, you can’t change the font or colour of the caption.
At the offer price of 69p it’s currently very affordable and good value for money.
Check out Camera+ in the iOS App Store.
