Looking at some of these lovely photos, I feel as if I do not use my phone camera properly.
I need to do better...
The thing to do is to learn basic principles of photography, techniques which can be utilized regardless of the particular camera one has in hand. There are books, there are video tutorials online, and lots of information is available. Good shots come from good photographers, and the tool that they use is secondary, although of course a camera with a lot of sophisticated bells and whistles is going to enable the shooter to create some effects and certain results which aren't going to be possible with another type of camera (i.e., a high-end full-frame camera with a 35mm sensor and really good lens is going to offer much more than an inexpensive P&S or a pinhole camera). That said, it is interesting what kinds of results can come from a pinhole camera or a simple P&S even though the user has little control over the settings! iPhones are pretty sophisticated little devices and I have been surprised time and time again at the quality of images I've seen shot with one.....
In a nutshell, photography is about light. Capturing light, playing with light, creating interesting effects with light..... You can do that on an iPhone just as you can with a high-end camera with a $12,000 lens on it. iPhone is easier to carry around and for most of us is always with us, and as the old adage goes, you capture photos with the camera that is with you.... The image I shared yesterday is one that I shot with the iPhone while at the grocery store, and while it is certainly not a wall-hanger or something to be exhibited in galleries, nor was it meant to be, it was just a little something that caught my fancy so I pulled out the iPhone and fired away...... That's the value of cell phone cameras, that spontaneity, that ability to capture a scene because it interested me.
People here shoot with whatever they have, and there's no "right" or "wrong" camera or lens, no "rules" about using certain gear or specific techniques here. Jump right in, the water's fine!
