With the iPhone 6s Plus, Apple made a thrust into the world of serious photography. They created advertising spreads with professional photographers showing off thier work using only an iPhone.
I decided that I'd work on my skills in this arena. I studied from the iPhone Photography School. Some of the work I did for these courses is shown in a gallery below. While they offer a number of very fine classes, there is also a wealth of knowledge available from their site for free. I recommend joining thier eMail program, if you are interested in bettering your iPhone photo skills.
I have made presentations to various Apple and photo groups. CLICK HERE for more information.
In 2018, I offered a summer-long class as part of the Summer Citizens program at Utah State University. I offer some of my work from that time frame. For the work that my students did, CLICK HERE.
