Take Better Range and Gun Photos with Daylight Fill Flash

camera daylight fill flash shootingWe know you guys like taking photos of your rifles at the range. And, if you’re selling a rifle, scope, front rest, or rear bag, you need good photos to post in our Forum classifieds. Here’s a basic photography tip that can help you produce dramatically better photos. Use your camera’s ability to add “fill flash” even in daylight.

There’s plenty of light on a bright day. But bright light also means strong shadows. The shadows can leave parts of your subject literally in the dark. Daylight flash will help fill in those dark spots. In addition, if you are on a covered firing area, and want to include the range in your photo, you can benefit from using flash. This will prevent the foreground subject from being too dark while the downrange background is much too bright.

Photo without Flash

The photo above was taken without flash. As you can see, the rifle is too dark so details are lost. At the same time, the background (downrange) is over-exposed and washed out. The second photo below is taken with daylight flash. The difference is dramatic. Now you can see details of the rifle, while the background is exposed properly. Note how much easier it is to see the the targets downrange and the colors of the front rest. NOTE: these two photos were taken at the same time — just seconds apart.

How to Activate Daylight Flash
Most digital cameras have daylight flash capability. Some cameras have a separate setting for “auto fill flash”. On other cameras, you’ll have to set the camera to aperture priority and stop down the aperture to force the flash to fire. Read your camera’s manual. On many Canons, a menu that lets you set the “flash output”. For “fill flash” we like to set the flash at 30% to 50% output. This fills in the shadows sufficiently without “killing contrast” or creating too much reflection on shiny metal. Below is a photo taken with 30% flash output. Note the rich colors and how the exposure is balanced between foreground and background. Without flash the sky and target area would be “washed out”.


Here’s another tip for Canon owners. If you like deep, rich colors, use the “Vivid” setting in the effects menu. This punches up saturation and contrast.

Changing Primer Type CAN Alter Pressure and Velocity

Primer Wolf CCI Federal Muzzle velocity FPS reloading

We are often asked “Can I get more velocity by switching primer types?” The answer is “maybe”. The important thing to know is that changing primer types can alter your load’s performance in many ways — velocity average, velocity variance (ES/SD), accuracy, and pressure. Because there are so many variables involved you can’t really predict whether one primer type is going to be better or worse than another. This will depend on your cartridge, your powder, your barrel, and even the mechanics of your firing pin system.

BE SAFE: Be cautious when changing primer types. Glen Zediker recommended decreasing your load ONE FULL GRAIN when changing to a different primer type, one that you haven’t used before.

Interestingly, however, a shooter on another forum did a test with his .308 Win semi-auto. Using Hodgdon Varget powder and Sierra 155gr Palma MatchKing (item 2156) bullets, he found that Wolf Large Rifle primers gave slightly higher velocities than did CCI-BR2s. Interestingly, the amount of extra speed (provided by the Wolfs) increased as charge weight went up, though the middle value had the largest speed variance. The shooter observed: “The Wolf primers seemed to be obviously hotter and they had about the same or possibly better ES average.” See table:

Varget .308 load 45.5 grains 46.0 grains 46.5 grains
CCI BR2 Primers 2751 fps 2761 fps 2783 fps
Wolf LR Primers 2757 fps 2780 fps 2798 fps
Speed Delta 6 fps 19 fps 15 fps

You can’t extrapolate too much from the table above. This describes just one gun, one powder, and one bullet. Your Mileage May Vary (YMMV) as they say. However, this illustration does show that by substituting one component you may see significant changes. Provided it can be repeated in multiple chrono runs, an increase of 19 fps (with the 46.0 grain powder load) is meaningful. An extra 20 fps or so may yield a more optimal accuracy node or “sweet spot” that produces better groups. (Though faster is certainly NOT always better for accuracy — you have to test to find out.)

WARNING: When switching primers, you should exercise caution. More speed may be attractive, but you have to consider that the “speedier” primer choice may also produce more pressure. Therefore, you must carefully monitor pressure signs whenever changing ANY component in a load. Glen Zediker recommends decreasing your load ONE FULL GRAIN when changing to a different primer type, one that you haven’t used before.
