3 important elements to master the art of photography
Photography is nothing short of an art form, which is why understanding the basics before you can even think of buying a professional grade camera for practice is essential. The right equipment, coupled with the right set of skills will help you go a long way and maybe one day even enable you to make a living out of taking pictures and auctioning or selling it to stock photo agencies. The concepts of camera and photo basics are applicable for still as well as digital photography.
A Digital Single Lens Reflex or DSLR camera is the best and basic equipment in professional photography to get started with the basic camera and photo concepts. Three very important points to understand while taking a picture include the shutter speed, aperture, and ISO (light sensitivity).
Shutter speed
- The shutter speed refers to the movement of shutter elements in a professional grade camera that allows you to capture different types of images.
- It refers to the time taken by the shutter to open and shut, allowing the light to fall on camera sensors for the image to be created.
- Low shutter speed and high shutter speed images can be achieved by moderating the shutter snap. The concept behind shutter speed is quite simple, the longer the duration of which shutter remains open, more is the time allowed for light to enter and create the image on sensors and vice versa.
- High shutter speed will allow photographers to capture high-speed images, like a race car or any fast moving object without the image getting blurred.
- Low-speed shutter imaging allows for standard photography, with the universal shutter speed set at 60 which is 1/60th of a second to capture the image.
Aperture
- While shutter speed controls the duration for which light can enter, aperture controls the amount of light which is permitted on the sensors. This will determine whether the captured image is too bright or too dark, depending on the aperture settings.
- Aperture has to be adjusted according to different lighting conditions to capture a perfectly created image, which is not too bright or dark without compromising any of the elements within the frame.
- Aperture also controls the depth of field which also modulates the foreground and background objects composed within the frame.
- Higher the aperture setting more will be the depth of field allowing decreased focus on a particular object and vice versa.
- A shallower depth of field will allow more focus on the foreground objects, by blurring the background.
ISO
- Also referred to as light sensitivity, the ISO is adjusted keeping in mind shutter speed and aperture to determine the perfect exposure for any image.
- In simple terms, the sensor will not be very sensitive to light with a low ISO number as opposed to a higher number that indicates high sensitivity.
When shutter speed, ISO, and aperture are all combined, the exposure levels can be modified with ease to find the perfect balance between all colors. It takes a considerable amount of time and practice to find the right balance between all three after understanding the theory of all camera and photo concepts.
It is also important to understand the composition of any camera and photo shot since what will be included within the frame will determine aspects like shutter speed, aperture, and ISO settings after the proper white balance has been done. White balance is done to produce true RGB colors for the image by calibrating the camera settings to pure white color composition preset.
The composition also depends on camera and photo concepts like rule of thirds, looking direction, head room, nose room and distance from the object you want to capture. This will again depend on the type of object or type of landscape you want to capture in your frame and composition.

Why should you get a bone density test?
Read moreA bone density test is a test that is performed to gauge the strength of the bone. The density of the bone is measured and the chances of fractures and osteoporosis are determined. It is a simple noninvasive test, where a dual x-ray absorptiometry scan is performed. It is mostly done in the spine, hip, finger, wrist, or heel.
Why you should get a bone density test?
Fractured bone
If you have had a fracture previously or are prone to such incidents, it is recommended that you immediately get a bone density test. If bone density is low, then there are more chances of fractures. A bone density test will help doctors to determine if the fracture is due to any underlying causes. It can be treated by medicines and a diet filled with vitamin D and calcium.Lost height
If you have a recorded measure of the decrease in height, get your bone density tested immediately. There’s a chance that the decline is due to low bone density. Although such cases are very rare, it’s better to be on the safe side and get yourself tested as soon as possible.Severely underweight
People who are severely underweight (below 127 pounds) should also get their bone density tested. Not only are they weak, but their bone density can be very low. This increases the chances of fracture with even small impacts to the bone. The low weight could be due to improper consumption of food and inadequate nutrition. This also means that the person might not have the required calcium intake. That leads to bone density. Hence it’s important that people who are underweight get a bone density test.Received a transplant
If you have recently received a transplant, then you should be aware that the body will take some time to adjust itself to the new organ. The time it takes might cause fluctuations in bone density. In these cases, it’s important to get yourself tested and monitored so that there’s no issue that develops.Drop in hormone levels
If there is a sudden drop in hormones due to medication or steroids you have recently taken, you must get a bone density test. There are high chances that the drugs can cause adverse effects to your bone density level.Family history of osteoporosis
If you have a family member who was diagnosed with osteoporosis, then there is a chance that you might suffer from it as well. It’s been found that it can be passed on from one generation to another. Since it can be treated at the initial stages, get regular bone density tests. These tests can reveal if there is any drop in bone density.Women aged 50 and above
Since women above 50 go through menopause, estrogen production in their body decreases. This has adverse effects on bone density. It has been shown that women may experience 2530% bone loss in the first five years after menopause. Hence, frequent bone density tests should be taken and diet should be modified accordingly.
Smoking, hyperthyroidism, and physical inactivity can also lead to problems with bone density. It is important to follow a balanced diet that has increased amounts of vitamin D and calcium to keep bone density levels in check.
