In one sentence, describe what the following article is about: Remove the old lens from your camera, either by pressing a lens release button or twisting the lens off. On 1 end of the 50 mm lens, you should see 2 marks. Align these with the corresponding marks on the camera and press the lens down. Turn the lens clockwise until you hear a click. Lenses may vary based on the manufacturer. For more instructions on how to attach a lens to your specific camera, read the manual that came with your camera. In most cameras, you will do this by turning the dial to “M” or by pressing the “Mode” button. Manual mode allows you to choose your own shutter and aperture settings. Once you are in manual mode, the screen of your camera should allow you to select both shutter and aperture settings. Refer to your camera's manual for more instructions. Shutter speed is the length of time that the shutter is open. It is measured in fractions of seconds. The general rule for shutter speed is to divide 1 by the focal length of the lens. This is the slowest shutter speed you should use.  Use a faster shutter speed, such as 1/125 or 1/250, to catch fast moving objects like cars or birds. If you want more blurred movement in your photograph, choose a slower speed, like 1/60. If you're in a dark or low-light area, choose a shutter speed of 1/250 or faster. Aperture affects the exposure (or brightness) and the focus of your photograph. A larger aperture will have more background blur and a brighter exposure. A smaller aperture will have less blur and a darker exposure.  Apertures are measured as "f stops." The smaller the number, the larger the aperture is. For objects that are far away in normal light conditions (such as landscapes, architectural photos, or group pictures), select an aperture of f4 or f5.6. If you’re working in low-light conditions or close up (such as portraits or still life), use a f1.4, f1.8, or f2.8 setting.
Summary: Attach the lens to the camera. Turn your camera to manual mode. Change the shutter speed to 1/50 or faster. Adjust your aperture settings.

In addition to increasing the risk of developing emphysema and lung cancer, smoking also increases your chances of developing an aneurysm.

Drinking too much alcohol can also weaken blood vessel walls, increasing the possibility of developing an aneurysm. If you have other problems related to excessive drinking, you may need to give it up entirely. Abusing drugs, prescription or otherwise, can lead to inflammation in blood vessels and the formation of aneurysms.

You don't have to start dead-lifting heavy weights or running marathons. Do sets of 20 sit-ups and 10 pushups to get started with and gradually work your way up. Check out some exercise videos online or at your local library for some guided instruction, or talk to your doctor for more possibilities. Key factors to avoiding an aneurysm or preventing one from rupturing include monitoring your weight, cholesterol, blood glucose and blood pressure levels. Scheduling regular doctor's visits and staying on top of your health is the best way to avoid aneurysms altogether.

Problem: Article: Organic hypoglycemia is caused by medical conditions such as liver or kidney disease, certain tumors, or hormone deficiencies; addressing the underlying cause is the treatment.  Hypoglycemia also can be caused by some medicines, especially ones used to treat diabetes.  Do not change your diet before a trained medical professional rules out other causes and diagnoses you with reactive hypoglycemia. Your new diet should meet the Dietary Reference Intakes (DRI) in terms of the calories, proteins, minerals, and vitamins needed for a healthy adult.  A dietitian can guide you as you add and remove foods from your diet.  They will assist you with planning the content of your meals and snacks. Let others know about your diagnosis.  Everyone can look out for symptoms like anxiety, irritability, hunger, sweating, shakiness, rapid heartbeat, fatigue, tingling around the mouth, dizziness, and hot flashes.  Break your diet and eat sugary foods.  The goal is to get your blood glucose back to a normal range as soon as possible  Let friends, family, and co-workers assist you with getting medical attention if you should develop symptoms of worsening hypoglycemia such as confusion, abnormal behavior, blurry vision, seizures, and a loss of consciousness.  Let them know you may slur your words and make clumsy movements similar to an intoxicated person.  You can become symptomatic for two reasons.  Your body inappropriately begins the process of decreasing your blood glucose to unusually low levels after digesting food.  In response to this stress, your body releases a rush of adrenaline, causing a fight-or-flight response.  In addition, your body is being deprived of its major source of energy, glucose.  The brain is very sensitive to this lack.  You may experience an inability to perform normal tasks, changes in your mental status (how you think), or changes in your level of consciousness (how awake you are).
Summary:
See a doctor to rule out other causes of hypoglycemia. Seek the advice of a registered dietitian. Monitor yourself for the symptoms of hypoglycemia.
