Photographic Exposure

'Correct exposure' is what we have when a photograph looks right-not too dark and dense, not washed out, pale and grey-and the details look bright and clear. But correct exposure is almost always a compromise. Films can handle only a limited range of brightness, which is why the best results are obtained in hazy lightning rather than in harsh sunlight. There are frequent occasions when a photographer must decide whether to expose for the highlights or for the shadows. When there is even lighting from all over the scene the problem of which part to expose for does not arise. The range of contrast falls within that which film can handle, so that highlights and shadows alike are full of detail. The better we understand light the more accurately can we visualize how our finished picture will look. Severe underexposure, for instance, will cause dense black in our pictures. We might get this when photographing a cottage in sunshine with the door open: the interior will be very dark. The blackness is caused by absence, or insufficiency, of light beyond the open door. And even though our eye may perceive details inside, if nothing is bright enough to record on our film everything beyond the door will go black.

Fishing in Ocean

They use a fishfinder. It's a device that sends out sound waves. The waves bounce off schools of fish and are reflected back to the boat. the reflections are like echoes, but they appear on the fishfinder's screen and show people where the fish are. A fishfinder operates in the same way as radar except that a radar set uses radio waves, while a fish finder uses ultrasonic waves. These waves emitted from a fishing boat are easily reflected when the an object under the sea because they have a short wavelength. Sound waves with a longer wavelength, such as those employed in radar detection, cannot be used because that type of sound wave is not easily reflected beneath the surface of the water.

My kind of song

"Down in a hole" is the best song Alice In chains ever made. The track is beautifully composed and is highly atmospheric and the haunting guitars and soothing vocals are extremely addictive. composed by guitarist Jerry Cantrell, he initially hesitated to show it to the rest of the band fearing it might be too soft for the band's signature hard rock/heavy metal sound. But when the rest loved it, the band turned the initially simple track into one of the best songs ever made.

There are two amazing versions : the original electric hard rock version appeared on their "Dirt" album and the acoustic version for their MTV Un plugged performance. Both are good but the acoustic one is much softer and mellower. Layne Stayley's voice is heavenly and Mike Inez's bass playing is just awesome on the acoustic version. A fluid lead guitar by Cantrell is mesmerising as is stayley's soulful rhythm full of lush chords and detailed atmospherics. The tracks was a major hit and defined 1990s rock.

Take control of your Emotions

Emotional trauma needs no introduction. Whether it is the loss of a loved one, failure in a chosen career or the death of a cherished relationship, the resultant mental anguish is more than some people can cope with. Emotional trauma occurs when an extreme life experience causes high levels of stress that shatter the individuals ability to cope or logically process the occurrence and generate a solution.

Indications: such psychological distress is characterised by elevated anxiety and emotionality, by elevated anxiety and emotionality, extreme sensitivity, withdrawal, regression to childish methods of coping, taking rash decisions, depression, neglecting responsibilities and loss of self-esteem. Reactions such as guilt and feelings of insecurity and isolation some times lead to extreme actions like suicide or homicide. It is not uncommon to lose focus and the ability to think rationally. This often induces at risk persons to resort to behaviour that is further damaging What can be done: Dealing with emotional trauma is crucial not only to help the individual live a normal life, but also for others around them. Disturbing past experiences and an obsessive fear of failure plague the traumatised. It is important to help them realise that it is possible to take control of their intensified emotions, and get over the awful phase that they are going through. Cognitive behavioural therapy helps identify and alter self-critical and faulty thought patterns that may trigger the trauma. It also helps to explore causes of the symptoms and work out any conflicts in relationships that have a negative influence.
