I have just gotten into photography and I love it!
What type of pictures do you like to take?
I love taking pictures of my son. I am still learning and wondering if I need a better camera. What's your favorite camera?
Any camera with a good lens that focuses the light reflected really well, like Cannon perhaps
Is there anything else I need to look for in a camera?
Maybe something with 24 megapixels and a burst rate of 5 FPS would be good to start with
What about getting pictures developed? Should I go to Costco or do it online?
With Costco being the second largest retailer in the world, I'd say you can't go wrong by going there.
Do you know any good photo aps for my iphone? 
An app using Apple's iOS mobile operating system would be Snapseed or VSCO
