Red eyes in dogs can be the sign of some very serious underlying conditions in your pet, and if your pet eyes do start to turn red you need to be very concerned. It could be something very routine and simple to treat, but it could also be the sign of something very wrong with your pet. There is a huge misconception that pink eye or conjunctivitis is red eyes, but there could be nothing further from the truth. Conjunctivitis may be one of the symptoms of red eyes, but that is all it is; it is not red eyes.

How many countless photos have you taken at birthday parties, weddings, or bar mitzvahs that came back from your film developer with annoying red eye? The same thing can happen with animals, however, the result is usually a greenish or silvery glow. One of the most common problems novice photographers encounter when photographing people or animals is red eye. The problem is caused by the flash of the camera illuminating the rentina of the eye. With people the retina is made up of hundreds of tiny blood vessels. When lit by the camera's flash it reflects the red color of these vessels.
Many people use their eyes to convey emotion and add meaning to their facial expressions. Thus, it's no surprise that the eyes are one of the first things that people notice upon meeting someone new. Therefore, when you take pictures that have the annoying red-eye effect, it can take away from your desired image and distract from the subject.
The eye is a sensitive but strongly built organ. Like everything made of flesh and blood, it is also subject to some problems, most of which are the byproducts of modern lifestyles. But advances in eye health care more than make up for the harmful effects, and today people have a much better chance of retaining their vision into old age. The eye is a sensor that converts the reflected light from an object into a signal that the brain uses to identify the image.
Red eye is a major problem for amateur photographers and occurs when a built-in-flash unit is positioned too close to the camera. This is down to poor design of cheap cameras, but can also happen with the built-in flash units in most SLR cameras. Red eye is caused by light reflecting back off the retina at the back of the eye.
What everyone who suffers from an eye condition really wants is fast, soothing relief from the many symptoms associated with dry red eyes. These symptoms can range from mild irritation, dryness, and noticeable redness in the eyes, to excessive watering and itchiness of the eyes.
Red Eye is caused by light bouncing off the back of the eye and reflecting back into the camera lens. There are two conditions, working in conjunction, that lead to this. Low light conditions cause the iris of the subject's eye to open up, and the on-camera flash is close to the lens which allows the light to bounce almost directly back from the eye into the camera. This article will help you take steps to avoid red eye.
Nothing looks worse than shooting a great portrait only to find your subject's eyes have the dreaded Red Eye effect. It is disappointing at the least but it can also be infuriating, as often, you can't take the shot again. This may be because the same conditions may not exist if you try to re-shoot the same shot almost immediately or because you only notice the red eye effect later on and the opportunity has passed - like a wedding for example. So why not avoid it in the first place by following this simple guide?
