Make sure you're using the image whose data's been modified when you're applying the effects. You might be using UIImageView to hold the image on your view, now let's assume your UIImageView's object's name is imageView, so now you use imageView.image property when passing the image to the function which is posting image on twitter. You might be passing the original UIImage object which doesn't know about the changes you did recently.
