The iPhone makes for a great always with you photography device. The camera in each successive iPhone model is supposed to be markedly better than the previous one. Having pre-ordered and received an iPhone 6 on launch day, I was excited to see how much better its camera (two generations newer than my iPhone 5) was. I was at Pass-A-Grille Beach at the southern tip of St. Petersburg and was treated to a great sunset view. I made one photograph using the regular single exposure mode in the standard Phone app and then another photo right after using HDR mode. Sunsets are great for HDR as the sky is often much brighter than the foreground, however, there was little difference in the single exposure and HDR iPhone 6 photographs. The HDR one did produce a little better detail around the sun, but not enough in the rocks in the foreground.
This was just one test of a particular photography situation, but a very common one, and overall I disappointingly did not see much difference from past iPhone 5 shots. I will be testing out more shots using both the default Camera app and the pay Camera+ app on the iPhone 6.
