How to make the quality on my ipad 2 or iphone 4 front facing camera better?

Is there a free app I can download to make the pictures I take more clear?

Haha!

App? You only have to shoot under ideal lighting conditions to get good pictures.

I don't think you understand. It's well known that such cameras (if you can call them that) are pure junk.
There's no improving what's bad in the first place - garbage in, garbage out. Want real pictures… Buy a real camera.

This is another question that gets asked too often for my liking…

… I honestly don't know what is getting taught in schools or colleges these days, with audio and visual recording equipment you can manipulate and alter the captured 'file' (image or sound) however you can't improve on the original quality…

… That is why it is more important to know how to use equipment you are working with, and understand when and how to compromise in certain situations…

Apps really are more of an extension to your interest… If you are interested in improving your images the most sensible approach is to upgrade the device… To a dedicated camera, honestly there isn't any other way!

It's like asking if there's an app to make your car faster.

Why do you think an app can give you clearer pictures? A better camera is what you need.
