A Picture To Show You Clearly The Effects of Aperture, Shutter Speed and ISO On Images

A Picture To Show You Clearly The Effects of Aperture, Shutter Speed and ISO On Images

    Want to capture excellent photos? Then you need to understand three things — the aperture, the shutter speed, and the ISO.

    The aperture controls light that passes through your camera lens. If you shoot with the aperture adjusted to the smallest opening, the smallest amount of light is allowed to enter. Let’s say, you need to take a picture in an environment that’s too bright — how do you fix that? Simple — just choose a smaller aperture. The aperture’s sizes are measured by f-stops. A higher f-stop means a smaller aperture hole while a lower f-stop means a bigger aperture opening.

    Now, the shutter speed. It’s the duration of time a camera shutter is open to allow light into the camera sensor. Shutter speeds are usually measured in fractions of a second. Fast shutter speeds allow less light into the camera sensor and are used for high-light and daytime photography while slow shutter speeds allow more light into the camera sensor. Obviously, slow shutter speeds are ideal for nighttime photography.

    Finally, the ISO. ISO is all about the sensitivity level of your camera to available light. Usually, it’s measured by numbers. A lower number represents lower sensitivity to light while higher numbers mean heightened sensitivity. The drawback in using increased sensitivity is that it produces noisier images. Simply put, you end up with grainy pictures if you use high ISO.

    How do you take properly exposed photos, then? Those that are not too dark or too bright. The three – Shutter Speed, Aperture, and ISO – need to play together well. Let’s say it’s high noon. Of course, you have plenty of sunlight. If your camera aperture is very small you block most of the light. It means the camera sensor needs a longer time to gather light. Now, for the sensor to collect enough light, the shutter has to stay open longer. In other words, you need a slower shutter speed.

    How to Stay Calm and Cool When You Are Extremely Stressful

    How to Stay Calm and Cool When You Are Extremely Stressful

    Being in a hurry all the time drains your energy. Your work and routine life make you feel overwhelmed. Getting caught up in things beyond your control stresses you out…

    If you’d like to stay calm and cool in stressful situations, put the following 8 steps into practice:

    1. Breathe

    The next time you’re faced with a stressful situation that makes you want to hurry, stop what you’re doing for one minute and perform the following steps:

    • Take five deep breaths in and out (your belly should come forward with each inhale).
    • Imagine all that stress leaving your body with each exhale.
    • Smile. Fake it if you have to. It’s pretty hard to stay grumpy with a goofy grin on your face.

    Feel free to repeat the above steps every few hours at work or home if you need to.

    2. Loosen up

    After your breathing session, perform a quick body scan to identify any areas that are tight or tense. Clenched jaw? Rounded shoulders? Anything else that isn’t at ease?

    Gently touch or massage any of your body parts that are under tension to encourage total relaxation. It might help to imagine you’re in a place that calms you: a beach, hot tub, or nature trail, for example.

    3. Chew slowly

    Slow down at the dinner table if you want to learn to be patient and lose weight. Shoveling your food down as fast as you can is a surefire way to eat more than you need to (and find yourself with a bellyache).

    Be a mindful eater who pays attention to the taste, texture, and aroma of every dish. Chew slowly while you try to guess all of the ingredients that were used to prepare your dish.

    Chewing slowly will also reduce those dreadful late-night cravings that sneak up on you after work.

    4. Let go

    Cliche as it sounds, it’s very effective.

    The thing that seems like the end of the world right now?

    It’s not. Promise.

    Stressing and worrying about the situation you’re in won’t do any good because you’re already in it, so just let it go.

    Letting go isn’t easy, so here’s a guide to help you:

    21 Things To Do When You Find It Hard To Let Go

    5. Enjoy the journey

    Focusing on the end result can quickly become exhausting. Chasing a bold, audacious goal that’s going to require a lot of time and patience? Split it into several mini-goals so you’ll have several causes for celebration.

    Stop focusing on the negative thoughts. Giving yourself consistent positive feedback will help you grow patience, stay encouraged, and find more joy in the process of achieving your goals.

    6. Look at the big picture

    The next time you find your stress level skyrocketing, take a deep breath, and ask yourself:

    Will this matter to me…

    • Next week?
    • Next month?
    • Next year?
    • In 10 years?

    Hint: No, it won’t.

    I bet most of the stuff that stresses you wouldn’t matter the next week, maybe not even the next day.

    Stop agonizing over things you can’t control because you’re only hurting yourself.

    7. Stop demanding perfection of yourself

    You’re not perfect and that’s okay. Show me a person who claims to be perfect and I’ll show you a dirty liar.

    Demanding perfection of yourself (or anybody else) will only stress you out because it just isn’t possible.

    8. Practice patience every day

    Below are a few easy ways you can practice patience every day, increasing your ability to remain calm and cool in times of stress:

    • The next time you go to the grocery store, get in the longest line.
    • Instead of going through the drive-thru at your bank, go inside.
    • Take a long walk through a secluded park or trail.

    Final thoughts

    Staying calm in stressful situations is possible, all you need is some daily practice.

    Taking deep breaths and eat mindfully are some simple ways to train your brain to be more patient. But changing the way you think of a situation and staying positive are most important in keeping cool whenever you feel overwhelmed and stressful.
