To cooking? No... to fine dining? yes. A camera phone can never do professional grade photos, but for what most people use their camera phone for what they used to use a camera for, only now it's available 24/7. Most camera phones have better resolution than old cameras (for the most part), and produce great photos. Just imagine how many parents captured moments they never would have without a camera phone?
