These are done with my iPhone using a new camera app my wife turned me on to. This app is called Camera+ and cost 99 cents. All of the other camera apps I had, tried out, and have removed most were all freebies. But this new one here is easy to use and has a lot of edits available (again all easy to use with instant preview) and doesn't have a bunch of fancy shmancy stuff that I have no interest in. The flowering tree is in our front yard and I applied one edit to them - 'scenery' which acted as if I had a polarizing filter. I wish I had saved the original photos so you could compare, but did not.
This picture of Sinbad was done the late afternoon in my study just after downloading the new camera app. I took a test photo so I had something to practice with then realized how nice it looked with the sunlight and shadows. I then wished I had composed it some eliminating my desk, chair and crap. Went to take another but then the light was gone as the sun had dipped behind the mountains. Still an impressive picture done with a telephone camera app.
No, I am not selling my Nikon but these pictures make you wonder. I tried to run them through my usual two or three edits I always do with the photoshop program in my computer and they changed nothing. Thus these are straight out of the iPhone.
