There was a time in history when there was no awareness of the prostate is and how it functions. It is surprising how little many men know about such an important part of their anatomy. The prostate is an important segment of the male reproductive system. It is a gland that is located in the lower abdominal cavity, just below the bladder, in front of the rectum and behind the pubic bone. It partially surrounds the urethra. The urethra is the channel that carries urine to the penis from the bladder and it runs right through the prostate. A healthy prostate is about the size of a walnut, weighs approximately 1 ounce and is shaped similar to a donut. There are ?seminal vesicles? that are attached to the prostate.

They produce a protein that mixes with prostatic fluid which forms semen. How this works is that tubes from the testicles carry sperm up to the prostate where sperm is mixed with the seminal vesicle and prostatic fluids. This fluid is ejaculated during orgasm through ejaculatory ducts that connect to the urethra. In addition, the prostate helps to control the flow of urine.

Nearly every man will experience some type of prostate problem during their lifetime. Men who are over forty-five may experience an enlargement of the prostate. While this is not a life threatening condition, and there are treatments. In some cases surgery might be considered if the enlargement is significant. DIAGNOSTIC TESTING Prostate cancer can occur in any man but there are certain ?risk groups.? Younger African American men appear to have twice the risk and fatalities of Caucasians. Sadly, many are diagnosed before they reach the age of 50. The only method to determine whether you are at risk for prostate cancer is diagnostic testing.

The earlier you are screened the higher your chances of survival. The bracketing feature on most DSLR and EVF digital cameras vimax is sometimes unfairly ignored. Bracketing the exposure is not to be confused with the continuous feature that takes three or more exposures at the same value. The automatic exposure sensor in the camera does its best to supply the correct exposure, but since the window of good exposure is fairly narrow in digital cameras, a better exposure could be made.

The light sensor must rely on either average information across a representative section of image or in the case of a spot reading, a small area that may or may not be close to a mid range density. By exposing a subject one half or one third stop under exposed and one half or one third stop under exposed and one half or one third stop over exposed, an obvious difference in image quality will help you decide which one to keep for future enlargement. Most cases of poor image quality can be traced to an original under or over exposure. While it is true that the average image editor can correct for density mistakes, the end result will be a compromised version of the image, even though it is improved from the original. A properly exposed image will show better skin tones, whiter whites, deeper blacks and a more subtle range of tones in pastel colors. Years of shooting with exposure forgiving negative color film has spoiled us with the fact that two under exposure or three stops over exposure will be corrected in the printing. There is some correlation to slide film, especially the characteristics of Kodachrome. Transparencies often required the exposure to be within one half stop of the correct exposure to look at all good when projected. Few photographers carry around a gray card to check the color balance or take a spot reading of a face close up before taking the shot. The bracketing feature can save the day..
