Special techniques and special equipments are needed for underwater photography. Dedicated underwater housings and cameras are available which even prevents the regular cameras from getting wet. Without these underwater housing it is not possible to use the regular cameras under water. To get good images, the water between your camera and the subject should be less. Water has many particles in it which might reduce the clarity of the image. Moreover the lighting direction is also to be considered for proper photography. The particles in water would disperse the light or absorb the light. Hence proper care should be taken while taking underwater photography. Your exposure should also be correct when you are using flash under water. TTL ready units are available which help a lot in correct lighting. However it is the duty of the photographer to choose the right direction for lighting. Composition is an important element that should be considered after taking a shot.

Wireless internet has opened avenues for those who do not have access to proper infrastructure pipelines for internet. Traditional technologies like cable and DSL would not be feasible for some remote places. In such cases the wireless internet comes to the rescue. In wireless internet a communication tower beams the data to its subscribers. The radius to which it is beamed would be around 40 miles. Now-a-days more powerful towers are available for wireless internet. If you are away from the nearest tower then the satellite would be only option. Data from the tower is transmitted to the satellite and you would be having a dish like receiver which receives the data from the satellite. From the receiver data is piped to your desktop or laptop.

An 802.11b connection is used to transfer data to your laptop. To be precise the data from the transmission tower goes to your internet receiver that you have at home and from that receiver it is passed to your laptop or desktop. In some remote cases the satellite also comes into the picture.

Postures, breathing techniques, and focus on specific body parts are the key to yoga. With these you integrate the body, mind and soul. In yoga the postures are called as asanas and the breathing techniques are called pranayama. The postures or asanas help you to focus on specific body parts. You will be asked by your tutor to focus on a specific body part, for example on your spine. With such focus the connection between that particular body part and the mind is built. There is no way for diversion. The focus is internal. The breathing techniques which are in a controlled fashion help you to merge the body, the mind and your soul or spirit. Prana means energy and yama means social ethics. Breathing also helps you to focus on your muscles and during savasana you will be more relaxed due to slow down of heart rate and inner calmness. You get a sense of inner calm and relaxation.
