Links to the interesting articles I discovered during the week.
Harry GuinnessAt the moment there are four iPhone models for sale: the iPhone 6, 6 Plus, 5S and 5C. On paper they all have similar technical specifications, but the newer models have better image. All four iPhones have an 8 megapixel camera, but the newer models have better image quality because they have larger sensors. The cameras all have a fixed aperture 4mm lens; f/2.4 in the 5C and f/2.2 in the 5S, 6 and 6 Plus. Given the crop factor, the lens is equivalent to a 30 to 35 mm lens on a full-frame camera.
The iPhone has a shutter-speed range of 1/2000 of a second to 1⁄2 a second. The ISO range is 34 to 2000 in the 5S and 5C and a slightly wider range of 32 to 2000 in the 6 and 6 Plus.
It's interesting to know the photographic abilities -- and limitations -- of the iPhone 6. Not that much different than a Nikon F2.
I had no idea how little rainfall we had in New Jersey this summer until I took a trip out to Rock Brook in Skillman. I wanted to get some long-exposure images of the water I normally see flowing in the brook, but my wife wanted to pick up our produce from the Honey Brook CSA. I promised her we could get my photography done, stop in at 365 Grandview for the Montgomery Friends of Open Space sponsored "Hike for Kids", and still make it to the CSA. We headed out to Hollow Road with our daughter, who decided at the last moment to come along.
No long exposure photography at the Rock Brook on this occasion. The brook was dry and filled with leaves. But I love the colour of the leaves. I had left my Nikon in my car, but this was fortunate. I didn't get to do any long exposures, but I made good use of the available light offered by the day.
Normally, my daughter doesn't like posing for photos. Especially when I'm the photographer. But she seemed willing, yet not eager, to pose for a few photos on the rocks.
The little bit of water in the brook was filled with leaves.
