The best camera to use is the one you have with you, and I pretty much always have my iPhone camera with me. My iPhone is not only a camera, it is also a digital darkroom. Please click here to check out my new virtual gallery of iPhoneography by Harold Davis.

So, carpenters know to get the right tool for the job. If I need a high resolution original to make big prints I am likely to use a 36MP full-frame DSLR with one of my superb Zeiss lenses.

But for quick, impressionistic water-color-like images, such as the ones shown here, my iPhone and the Waterlogue app are just the ticket! Waterlogue is certainly not the only iPhone processing app I use, but it is my go-to software when I am looking for a soft, dreamy water color look.

I shot this image at Monet’s Garden, Giverny, about an hour outside of Paris. I used my iPhone camera app. I used my bracket to place the iPhone on my tripod, and the ear bud as a shutter release. On the bus ride back to Paris, I processed the image on my phone using the nifty Waterlogue app.

Today the city of Cahors in the southwest of France is a slightly gritty provincial capital—but back in the middle ages it was fabulously wealthy. Protected on three sides by the river Lot, Cahors was nevertheless sacked, abandoned and rebuilt. But glory was never regained entirely (the Black Death didn’t help matters). You can see the remnants in the palaces and monuments of the old quarter, where today they have a wonderful fresh food market. I got my lunch today in this market. You really can’t beat a fresh loaf of bread, a tranche of locally made pate, strawberries and a tomato!

Cahors may have fallen to brute force and treachery during the hundred years war during the convoluted battles between French and English monarchs, but the Pont Valentre, shown above and below via iPhone capture, was rightly regarded as impregnable.

Over the years, I have photographed the beached and slowly decaying Point Reyes trawler, located near Inverness, California, by starlight and by daylight in the afternoon. This photo was by iPhone, made while my boys clambered over the wrecked vessel.

Photographed on my iPhone, and processed on my phone on the spot with the nifty Waterlogue app. Here’s another one:

The Royal Air Maroc plane to Lisbon was late to leave, as expected. Still, it was a relief to leave the chaos of Casablanca as we said goodbye to Morocco. Surely an adventure with many images to process, and much to digest. I captured this image on my iPhone, and processed it with Waterlogue.
