I was pretty sure that among the 200-some-odd photos I had taken, there had to be an octopus somewhere.

By opening up the shadow areas and toning down the highlights in iPhoto, the values are redistributed to more closely resemble the actual scene. However notice the reflection in the lower left quadrant of the screen.

In the small dark cavern, I would have completely missed the fact that the octopus was there at all had I not made the quick adjustments that open up the shadow details. I performed the adjusted preview in iPhoto on my Macintosh, but Microsoft’s comparable software is Windows Photo Gallery.

I learned lots of valuable lessons in photojournalism classes, many long forgotten, but a couple of lessons really stuck. Thirty years ago when, as students, we were advised to Shoot a lot, our biggest complaint was the cost of film.  Today, the cost of digital equipment pales when compared to film and processing costs, so I was surprised to learn that one of my companions on a day-long adventure to the Aquarium of the Pacific was throwing away photos after she previewed them on her iPhone, deciding they didn’t “turn out.” I wondered how it was possible to make such a quick decision about the images under such poor conditions and on such a small screen.

The next day, I showed my companion a rough edit slide show of my 230 images. I put them up on the big screen tv. She, on the other hand, had only 13 images, which we viewed on her iPhone. Granted she’s not a fanatic like me, and didn’t shoot as much as I did, but I can’t help by thinking about the photos she threw away. “What if there were details in the image that she missed on the small preview screen?” I wondered. “What if she could adjust her lighting after the fact?”

The reflection in the previous images has been replaced using the “content-aware” feature in Photoshop.

My first task after downloading photos to the computer is to make preliminary adjustments to the tonal values in the images. It’s a relatively “quick” and painless process, and I finished this batch in about 2 hours, or about 30 seconds per image. Unless you are serious about photography, you might unwittingly skip this most critical step, so that’s where the hording comes in to play. Don’t throw away any photos before you perform a quick adjustment to the image’s tonal values.

In the edited photo, the reflection in the lower left is more obvious than before, so I bring my photos into Adobe Photoshop where I make all the actual refinements and adjustments. To eliminate the glare, I made a feathered rectangular selection and filled the area using the “content-aware”  feature, which gathers data from nearby pixels to simulate the surroundings.
