TAKING YOUR TEMPERATURE

By MICHAEL PERKINS

AMERICANS LOVE TO CELEBRATE A WINNER, and they also like to clearly identify who most definitely did not win. We score-keep on everything from fantasy football to number of days on the job without accidental amputations, and we love, love, love to declare someone the champ…in anything. This either/or, winner/loser habit of the western mind, when applied to photography, leads people to argue over which is better…traditional cameras or those imbedded in mobiles, as if such a judgement is possible. Or as if it matters. So, as you rifle through these humble pages, I hope I make it abundantly clear that, from my standpoint, it’s all about the pictures.

Changing the white balance from auto to shade warmed up the colors in this nearly-outdoor shot. 1/25 sec., f/5.6, ISO 800, 35mm.

The principle difference between, say, DSLRs and phone cameras, to me, is one of method, or how they approach the job of making an image. In full-function cameras, the emphasis can be on how to use the device’s controls and settings to set the terms of your picture before the click. In cellphone cameras, it’s all about how you can massage what the camera was able to give you after the fact, be it with in-phone apps or computer software. You simply can’t impose your will on an iPhone camera until after the picture is taken, and that’s an important distinction. Notice that I did not say better/worse, great/horrible. You just have to decide what’s important to you in a given situation.

Take a very simple choice that is available in even basic point-and-shoot “camera-cameras”, like white balance. Your camera has the option of deciding, for you, how colors should register based on the temperature of the light, or you can over-ride that function and customize it to your heart’s delight, something that, at this point in time, cannot be done on a cellphone camera. Even easier, menus reduce all your white balance options to visual icons (sunburst, house in shade, electric light bulb, etc) depending on how warm you want your pictures. You can even tweak for the precise kind of artificial light you’re working with, from incandescent to flourescent.

As an example, in the above shot, the morning light in the hotel lobby was, on automatic white balance, coming off blue, especially in the shadows. The entire effect of the golden period just after sunrise was being subverted by the camera. Easy fix: just dial it up for a shade setting, bump up the exposure a tad (slower shutter, higher ISO), and the warmth came back, but not so deep that everything went bad-suntan-bronze. And, yes, I could have got this shot with an iPhone, but the adjustment would have had to have been made after I got the shot wrong, then searched around for a fix. Again, there’s no good or bad.

You just have take your own temperature and decide what treatment you need.
