Pixels- a minute area of illumination on a display screen, one of many from which an image is composed

Image resolution– a minute area of illumination on a display screen, one of many from which an image is composed

Megabyte- a minute area of illumination on a display screen, one of many from which an image is composed

Megapixel – a unit of graphic resolution equivalent to one million or (strictly) 1,048,576 (220) pixels.

Gigabyte- a unit of information equal to one billion (109) or, strictly, 230 bytes.

jpeg- a format for compressing image files.

raw-  a file that contains minimally processed data from theimage sensor of either a digital camera, image scanner, or motion picture film scanner.

tiff- The ability to store image data in a lossless format makes a TIFF file a useful image archive, because, unlike standard JPEG files, a TIFF file using lossless compression (or none) may be edited and re-saved without losing image quality. This is not the case when using the TIFF as a container holding compressed JPEG.

PNG- (pronounced ping as in ping-pong; for Portable Network Graphics) is a file format for image compression that, in time, is expected to replace the Graphics Interchange Format (GIF) that is widely used on today’s Internet.

Histogram- is a graphical representation of the distribution of numerical data. It is an estimate of the probability distribution of a continuous variable.

Aperture– a hole or an opening through which light travels.

Shutter speed- the length of time when the film or digital sensor inside the camera is exposed to light, also when a camera’s shutter is open when taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time.

Depth of field- the amount of distance between the nearest and farthest objects that appear in acceptably sharp focus in a photograph.

Noise- The occurrence of color dots or specks where there should be none.

Lag time- Refers to latency, or lag measured by the difference between the time there is a signal input, and the time it takes the input to display on the screen.

Hot shoe- A mounting point on the top of a camera to attach a flash unit and other compatible accessories.

Fisheye- A lens of small focal length, having a highly curved protruding front element, that covers an angle of view of almost 180°.

Aperture priority- a setting on some cameras that allows the user to choose a specific aperture value while the camera selects a shutter speed to match, thereby ensuring proper exposure

Shutter priority- a setting on some cameras that allows the user to choose a specific shutter speed while the camera adjusts the aperture to ensure correct exposure.

Bitmap- mapping from some domain (for example, a range of integers) to bits, that is, values which are zero or one. It is also called a bit array or bitmap index.

White balance- the process of removing unrealistic color casts, so that objects which appear white in person are rendered white in your photo.

Exposure-the act of exposing, laying open, or uncovering:

 

Watermarking- a kind of marker covertly embedded in a noise-tolerant signal such as an audio, video or image data. It is typically used to identify ownership of the copyright of such signal.

 

Optical Zoom- allows you to zoom in (or out) on the subject in the LCD or viewfinder. This will enable you to get a closer view of the subject before taking your picture.

 

Macro ~ a lens suitable for taking photographs unusually close to the subject.

Telephoto ~ a lens with a longer focal length than standard, giving a narrow field of view and a magnified image.

Wide Angle ~ (of a lens) having a short focal length and hence a field covering a wide angle.

DSLR ~ A digital single-lens reflex camera (also called a digital SLR or DSLR) is a digital camera combining the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film.

Digital zoom: is a function of a digital camera used to make the image seem more close-up.Digital Zoom on a digital camera works the same as cropping and enlarging a photo in a graphics program.

bracketing: place (one or more people or things) in the same category or group.

light meter:an instrument for measuring the intensity of light, used chiefly to show the correct exposure when taking a photograph.

Image stabilization: (IS) is a family of techniques used to reduce blurring associated with the motion of a camera or other imaging device during exposure.

Dynamic range-,is the difference between the smallest and largest usable signal through a transmission or processing chain or storage medium. It is measured as a ratio, or as a base-10 (decibel) or base-2 (doublings, bits or stops) logarithmic value.

Digital negative- (DNG) is an open lossless raw image format written by Adobe used for digital photography. It was launched on September 27, 2004.

Exposure compensation- Exposure compensation is a technique for adjusting the exposure indicated by a photographic exposure meter, in consideration of factors that may cause the indicated exposure to result in a less-than-optimal image1.

Topic: A couple was arrested for selling “Tickets to Heaven.”

 

Title of Article: Couple Arrested for Selling “Tickets to Heaven.”

 

Article Source: Huzzlers.com

 

Summary: The article briefly goes over how a married couple, Tito and Amanda Watts, were arrested for selling tickets to Heaven at $99.00 per individual ticket. The selling of these tickets in of itself would be legal, however Tito told the buyers that they were made of solid gold when the tickets were in fact made of wood. The excitement doesn’t end there though, in the police report it was said that Mr. Watts claimed, “…And it was Jesus who give them to me behind the KFC and tell me to sell them so I could go to outer space.You should arrest Jesus because he’s the one who gave them to me and said to sell them. I’m willing to wear a wire to set Jesus up.”

 

Reaction: This article has made me realize something deep and profound about my life. That ticket I bought was fake. I want a refund firstly. Secondly, I emphasize with Tito Watts. After all, I could be convinced that that ticket was made of gold, it sure felt like it anyway.


World Impact: This article really drives home the fact of how disgusting this world is now. That i can’t go behind a sketchy KFC and trust a man when he says that he’s Jesus. Truly this world is going downhill and fast. On another note I am pleasantly surprised that Tito was so generous as to volunteer to set up that foul crook “Jesus.” Perhaps there is hope for our world’s future.

Nine Essential Amino Acids

Nine Essential Amino Acids

 

By: Thomas Herndon

 

Histidine- cell replication and division; important in children; but new evidence now includes importance in adults as well.

Deer, boar and antelope are each a top source of histidine. Pork is also a good source, regardless of the way it is prepared.

 Isoleucine- it, along with two other amino acids (Leucine and Valine) promote muscle recovery after exercise. Another thing it does is it forms hemoglobin and assists with regulating blood sugar levels and energy levels. It also is involved in blood-clot formation.

Turkey, following by soy, chicken, lamb and crab. Many types of fish also contain isoleucine.

 Leucine- stimulates the release of insulin from the pancreas; protects muscles and increases energy production. promotes tissue healing and skin repair

Soy, seaweed and elk. However, egg whites are also an excellent source of this amino acid, as is chicken. Tuna is another great option.

 Valine- It has a stimulating effect and is needed for muscle metabolism, repair and growth of tissue and maintaining the nitrogen balance in the body.

Egg whites come in first when it comes to getting valine in your diet. However, watercress, spinach, seaweed, elk and turkey are also great options for this amino acid.

 Tryptophan- production of niacin; used to produce serotonin, important for normal nerve and brain function. Serotonin is important in sleep, stabilizing emotional moods, pain control, inflammation, intestinal peristalsis, etc.

Elk and sea lion meats. Other top sources for this amino acid include seaweed, soy, egg whites and spinach.

 Threonine- assists in the formation of collagen and elastin in the skin.

Threonine marks a refreshing break from meats and fish since the top source of this amino acid are raw watercress and spinach. However, you can still get this compound from moose, turkey or tilapia if you so choose. Egg whites and soy are also significant sources of threonine.

 Phenylalanine- associated with PKU; part of nutrisweet; the body converts phenylalanine into tyrosine, another amino acid that’s needed to make proteins, brain chemicals, including L-dopa, epinephrine, and norepinephrine, and thyroid hormones

Meat is the way to go for phenylalanine, which is found in the highest concentration in pork, beef, turkey, veal and lamb. Salmon is also a solid source of this amino acid, however, as are various flours, such as cottonseed flour and sesame flour.

 Methionine- assists with metabolic function, breaks down fat, and is the primary source of sulfur in the body. also critical for the removal of heavy metals, such as lead and mercury

As with many other essential amino acids, egg whites are the best source for methionine. However, fish like roughy, pike and tuna aren’t far behind. You can also eat meats like elk, turkey and chicken to get this amino acid in your diet. Lobster and crab are also among the top foods for methionine.

 Lysine- helps prevent herpes infections

Lysine is found in the highest concentration in chicken breast meat and turkey breast meat. However, fish is your next best option, with sunfish, ling, pike, tuna, cod, cusk and dolphinfish all being excellent sources of lysine as well. Though not as high in concentration, watercress, seaweed and parsley also contain significant amounts of lysine.
