9/24/2010: Back Creek iPhone HDR

Early morning light along Back Creek where it meets the Mousam River. This is an iPhone 4 HDR. With the 4.1 upgrade to iOS, HDR is now built into the iPhone camera, but, though very fast, it is pretty mild compared to the effects that you can get with the dedicated ProHDR app. The built in variety is great for opening shadows in difficult lighting, but for dramatic landscapes ProHDR is the app you want.

I am learning where HDR is appropriate and where it is not. This shot, for instance, did not benefit all that much from the HRD treatment, and I probably could have achieved the same results with a standard exposure and post processing…and there are a growing number of excellent post processing apps for the iPhone.

In this case, I straightened the horizon, sharpened the image, tweaked the color temperture, and adjusted shadows and highlights in PhotoWizard. The tools (filters) in PhotoWizard will be familiar to anyone who has worked with any variety of PhotoShop or most other dedicated image processing applications.

This version, with a bit more sky, made more of the HDR treatment.
