SITUATION WELL IN HAND
By MICHAEL PERKINS
A SELECTIVE READING OF SOME of the posts featured in The Normal Eye over the years might give the impression that I am “anti-flash” in my approach to photography. A closer look, however, would reveal that I am more properly non-flash….that, while I stipulate that judicious use of artificial light can be amazing, (a) it can often do more harm than good, and (b) there are fewer situations in which it’s needed than at any other point in time. So, anti……no. But non…..absolutely.
Choosing not to use flash in low light situations used to mean that a tripod was essential for sharpness in even reasonably quick exposures, but even that truth is falling by the wayside, as sensors allow for lower noise at ever-higher ISO levels. The handheld shot is now more convenient and reliable than ever, with only modest investments in gear and/or practice to yield suitable results. This means that, outside of very formalized studio settings, you may now be able to leave both flash and pod in the closet in more and more cases.
So let’s pursue the ideal: a low-light image, shot handheld, with the lowest possible ISO, achieved without flash or tripod. First, your glass needs to be fast, something that can’t be said for the basic kit lenses that are packaged with most DSLRs. A lens like a kit 18-55mm that only opens in the f/3.5 range can’t compete with prime lenses such as a 35 or 50mm of f/1.8 or faster. The extra several stops can render many more handheld shots feasible, and so investing in an affordable prime (single focal length) is money well spent.
The other, and far more decisive factors in this handheld quest, since you’ll be dealing in slower exposure times, are the purely physical moves involved in bracing your camera. Whether it’s a firm stance, a solid grip, a handy resting place like a shelf, or a combination of all three, you have to practice….a lot…in minimizing camera shake. Everyone’s technique for this will vary, and the web is rich in written or video tutorials from which to choose. The point is, it’s possible to learn how to do it.
The two shots shown here are both shot wide open, at F/1.8, at a rock-bottom ISO value of 100 and available light only (the room was actually further darkened for purposes of this test). And while you can certainly see a clear contrast in sharpness between the first and second shot, they are handheld at 1/5th of a second and 1 full second respectively and are both usable shots (seen here straight out of the camera). Moreover, even shooting at, say, 1/10th of a second or faster, the picture could still be done with very low ISO and no flash, no tripod. And that buys you ease, mobility and speed. Travel light, shoot more, and in more places.
Again, I am most definitely not anti-flash. I just think that the fluidity of today’s gear, along with a few hours of practice, can simplify your shooting, giving you more concentration on the why of a picture rather than the how of getting it done.
THE ONLY REAL PRIORITY
By MICHAEL PERKINS
THERE ARE MANY VALUABLE SERVICES OUR CAMERAS WILL RENDER without our consent or participation. Without even considering how many people shoot on full automatic 100% of the time, there are a hundred small calculations that these marvelous devices make to prevent the kind of errors in judgment that used to routinely trip us up, from autofocus and white balance, face detection and contrast control. However, there is a variable percentage of decisions on which we should really take personal action, despite the camera’s best efforts to, in effect, save us from ourselves.
In iffy light situations, for example, several key “semi-auto” modes are truly handy in helping us compensate for grey days or dark corners. One of these is called aperture control, in which you dial in the f-stop you want, based on your preferred depth of field, leaving the camera to set the shutter speed needed to properly expose at that aperture. At first blush, this seems to be a great short cut, and is in fact a neat option for people who are “running and gunning”..shooting lots of frames in a very quick time span. However, what looks like cutting your work in half can also mean cutting the legs off your creativity.
In the above situation, I had a severely overcast day in a lushly green Japanese garden. Without shadows for contrast, I would need colors to be as deep as possible to bring off the mood I was going for, so a slightly underexposed look seemed to be in order. Dialing in f/5.6 as a desired D.O.F. in aperture priority was giving me very slow shutter speeds as the camera tried to give me an ideal exposure. This made a handheld shot a little tougher and gave me way too much high color to suggest anything quiet or moody.
Going to full manual, I dialed in a shutter speed that would render the greens nice and deep, around 1/80, and bumped up the ISO a tad as insurance. It was true that I was shooting a lot at the same f-stop, but not so fast that I would have to surrender fine control by shooting in aperture priority for mere convenience’s sake.
I love some of the protections against my own folly offered by today’s devices, but I just can’t go completely driver-less and feel that I am taking enough responsibility for my results. Hey, if I blow it completely, I can still explain a lousy shot in two simple words.
