When you purchase your digital camera if you are like me you pick up the manual and start thumbing through it. You might also come across somewhere in that manual that talks about ‘aperture’. If you are new to photography you might actually ask what aperture is in relationship to your camera. We are going to explain aperture in this article for you and hope it give you a better understanding.
The main function of a camera lens is to collect light. The size of the diaphragm opening in a camera lens allows light to pass through onto the film inside the camera the moment when the shutter curtain in camera opens during an exposure process. The larger the diameter of the aperture, then more light reaches the image sensor. Aperture is expressed as f-numbers or f-stops. Those numbers you see on the lens like f22 or f/22 or f/8.0 and f/5.6. The smaller the F-stop number, the larger the lens opening on your camera. A “fast” lens is one that has a large maximum aperture like F2.4 or F2.0.
A good aperture range is my opinion is somewhere between F1.8 and F16. A larger aperture range will give you more latitude with the kinds of pictures you can shoot. The larger the aperture the better your camera will perform in low light situations and will help negate camera shake. A larger aperture also allows you to use a fast shutter speed for freeze action. Another advantage of a large maximum aperture is to provide a shallow depth of field. This allows the background to blur nicely thus isolating your subject. A smaller aperture also has its good qualities by using a slow shutter speed which can help show objects in motion. Another advantage of a small minimum aperture is to increase the depth-of-field. An increased depth-of-field allows you to take landscape pictures where as much of the picture in the foreground and reaching all the way to the background.
We hope this short article on aperture for digital cameras has helped give you a better understanding.

The C2 LED is a compact high-output flashlight featuring a Combat-Grip™ body. It uses a virtually indestructible power-regulated LED and a precision micro-textured reflector to produce a smooth 120-lumen beam—six times the light of a big two-D-cell flashlight. Its super-efficient, electronically regulated LED continues generating useful light levels for 11 hours on a single set of batteries. With no filament to burn out or break, the C2L’s solid-state LED is immune to recoil, and its patented flat-sided CombatGrip™ allows the flashlight to be easily held and operated when paired with a handgun, using the SureFire technique. When in the field or on the mountain make sure you have the Surefire C2L Centurian LED Flashlight to stay equipped while on the move.

SureFire flashlights are known around the world as the go-to lighting system for any and every tactical scenario. In 1969, their original product line consisted of laser sighting systems for firearms. After many years of intense research and development, the SureFire WeaponLight was born and low light law enforcement & military operations changed forever. SureFire then went on to establish themselves as the leading manufacturer of rugged, powerful and compact illumination tools for tactical applications; from weapon-mounted lights and laser sights, shield lights, baton lights & hand-held lights powerful and bright enough to qualify as force-multiplier tools that could temporarily blind, unbalance, and disorient a threat.

All parents want to take fantastic photos of their kids. Parents want professional looking photos without have to pay a fortune. You just get one chance to get those perfect shots of your baby before he or she grows up. Let’s face it, nobody wants to show the world a pink, shriveled face bathed in bad light. Here are some tips on getting great pictures.
Lighting is everything. The best lighting is natural sunlight, preferably on a slightly cloudy day. I would say the best time is early in the morning or late in the evening right before the sun sets If it is too bright out, you will get shadows and possibly a little one with squinty eyes. Remember to use your flash for fill flash outside. This lighting produces stunning results.
Get closer to your child. Fill the frame with your baby’s face and leave out the lamps and furniture and all of that other visual clutter. A good close-up of a baby can be other-worldly. Be sure and get down on there level. You don’t want to have a hundred pictures of your baby looking up.
Keep the background as simple as possible. It’s harder than it sounds, most photographers spend half there time trying to find a simple background.
Try and capture action. A baby sprawled on the blanket in my opinion is to ordinary. Capture the moment of your child doing something like yawning, crawling, playing with toys or whatever it might be.
Take lots of pictures. Don’t be afraid to keep snapping off shots. The more pictures taken the more choices you have to look at to see what was the best shot. Take tons of pictures of your baby and you will find one or two awesome ones in the batch. Digital cameras today can store a massive amount of photos, so let the picture taking rip.
We hope these few tips we have provided help when shooting photos of your children.

Gear: Some may prefer a point-and-shoot system; others may want manual control in a compact digital, while others may want a single-lens reflex (SLR) camera. So defining the ideal camera must start with the shooter’s needs. For a manual compact digital, the Olympus SP350 is great, and for SLR the Nikon D200 and D2x in Subal housings. For the point and shoot, there are several Olympus systems and even the SeaLife with a wide-angle lens.
Best use of your camera: Get a versatile strobe arm, such as the UltraLight, if you want to vary your lighting. This type of arm is for the diver who is comfortable in the water and wants to improve his style. For any camera, if there is a wide angle lens available, add it to your system.
Perfect Technique: Blurry photos are from too much movement or too slow a shutter speed. Master your balance and buoyancy because that is the most important part of getting great photos underwater. You can’t compose, adjust strobe angles and analyze your results if you are kicking, falling over and scaring your subject away.
Most common mistake: Shooting from too far away. You should take a photo, get closer and take another, and then get closer yet until either you can’t fit the subject into your picture area or the subject leaves. If the fish stays still, move in and shoot just the eye, but keep getting closer.
Here are a few other tips for underwater photography from 42nd Street Photo
- Get out and shoot. Find a place to dive near where you live.
- Don’t use digital zoom
- Make sure you understand the focusing distance of your camera in and out of macro mode. Use macro mode when you are within the macro focusing distance.
- Bring a dive light with you to help your camera auto-focus
- If you turn your flash off, either manual white-balance your camera, or set it to underwater mode
- Anticipate what you might see underwater, adjust your strobe, f-stop ahead. It would be big mistake, to see a shark and having your camera at F22
- Learn how to use your histogram and highlights screen, and use them often
- Use a 100mm or 105mm lens to emphasize or isolate the subject, and reduce the background
- Get the exposure right in camera; don’t rely on post-processing
