Digital photography tips: capture summer action

Follow these expert action photography tips to take top-notch images of subjects in motion.

Tweak the ISO

Sometimes, in spite of having an ideal subject, you still can't get the photo you want. Your subject might be front and center in the scene; but due to poor lighting, the shutter speed is so slow that everything is a blur.

The fix? Find your camera's ISO control and increase it a couple of steps. ISO measures your camera's sensitivity to light; shooting at ISO 400 instead of ISO 100, for example, means that you can possibly catch a photo at 1/60 second instead of 1/15 second. That's the difference between being able to read the letters on a player's jersey and ending up with merely a blur.

The downside to increasing the ISO is that you'll have more digital noise in the photo, but if increasing the setting makes the difference in getting a sharp photo, it's probably worth it. This wolf never stopped moving, for example, so a high ISO froze the action at the cost of making a grainy photo. Like white balance and manual focus, ISO is a setting that you should remember to change back after your action-photo shoot.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
