An overall camera/video camera question

Hi All, Just wanted to get your thoughts on what would be the best app to take pics with on the iPhone, the camera app, or any third party apps? I downloaded the Instagram app, which when you take a pic, gives you an option to write a caption, to I guess, indicate if a blind person was looking at a pic on Facebook, what the pic was. I also downloaded the Guided Photo Pro app, which gives spoken directions on where to point the camera while trying to take the picture. Do any of you label your pictures, and if so, do you have to label them in the camera roll, or bothe camera roll, and photos app? What are your opinions on taking pictures as a whole? Do you use the camera app itself, or a third party app of some sort? Also, what about recording video? Is there an app that will tell how to position the video camera while recording, or is that just a hypothesis one has to make, and practice with? Thanks for your feedback, Shane.
