It is an experimental image today. We just discovered, than when you chose a spot to focus on the iPhone, also exposure adjusts for this part of an image. Obvious? Yeah, but. The added feature- you can take HDR images with your iPhone :). You expose for several different spots, and then combine JPEGs in Photomatix. I have to admit, I still feel a bit hesitant to use too many sliders in Lightroom for JPEGs, I am so used to working with RAW files and I was wondering how the HDR will turn out as well. And I used only two images. But it seems to be working so far. The wind which moved grasses made the image even better, with the tower sharp.
