Conceptual is something to do with mental concepts or philosophical or imaginary ideas. An example for conceptual is when you formulate an abstract philosophy to people which it can’t be proven or seen. The conceptual phase is when initial phase of research involves the intellectual process of developing a research idea into a realistic appropriate research design. This phase can be time consuming depending on the level of expertise of the investigator. This phase time is spent critiquing the literature on the topic of interest continually refining and narrowing down the topic until a succinct research problem and purpose has been determined. Conceptual skills are thinking which leads you grasp complex ideas and come up with answers for difficult problems. These skills are valuable because they allow people to find many solutions for different challenges through deliberating thoughts and abstracting reasoning. This type of skill might allow managers comprehend relations between different departments link them to the functioning of the entire company and optimize how these elements interact. Thanks to these skills they can put many companies in the bigger picture plan its growth sees potential obstacles and develop contingency plans because of their concepts. Conceptual modeling is used to describe physical or social aspects of the world in an abstract way. In the realm of software development as conceptual model may be used to represent the relationships of entities within a database. Conceptual meaning is the literal or core sense of a word. There is nothing read into the term no subtext its just the straightforward literal dictionary definition of the word. Conceptual models are merely representations of abstract concepts and their respective relationships the potential advantages of implementing a conceptual model are many. Largely depend on your own ability to devise a strong model in the first place.
There is no right answer when people ask what lens I should get. The cost of the lenses depends on several things. Expensive lenses have a fixed aperture. Wide angles give an expansive view when they are used correctly, they can wrap you in the scene. Wide angles are used when prominent foreground objects are presented. Standard zoom lenses are versatile and allowing both wide angles work as landscapes or zooming in to the telephoto end of the lens to take great portraits. Prime lenses are lenses that are just one focal length. Telephoto zooms allow someone to stand back when the subject is not approachable or when the subject might feel overwhelmed by the presence of the camera. Telephoto lenses make everything appear closer as the opposite of wide angles make everything seem far away. Telephoto lenses are also excellent for sports, nature, and wildlife where it can be difficult to get close. To stop actions without blurring you need a fast shutter speed. Faster telephoto lenses have larger maximum apertures. Less expensive lenses will have variable apertures meaning as you zoom and the maximum aperture gets smaller. Fast lenses are usually one that has an aperture of F/4, F/2.8 or larger. Beyond all the usual types of lenses there are a variety of specialty lenses available like shooting tiny things. Using longer lenses can be challenging to track movement so it becomes much easier if the subject comes directly at you rather than to track movement parallel to the camera. Faster telephoto lenses have larger maximum aperture. DSLR systems offer a dizzy selection of lenses for their camera. This range from fisheyes that give a 180 field of view. You got zooms, prime, Marco, super telephoto and of course tilt – shift lenses as well.
Depth of Field is referring to how much of the picture you are trying to choose to have in focus. You can bring attention to your subject by reducing the depth of field in a scene or making the background soft and blurry. If you are not experimenting with your aperture settings and missing out on one of the most useful tools in a photographer’s arsenal. To get your viewer’s attention in a specific place you must choose how much depth of field to have in your shot. First rule for understanding aperture and depth of field is very simple the larger the aperture the shallower your depth of field will be meaning a smaller portion of your image will be in focus. Once you figure out how to control your aperture you must figure out how much depth of field you want in your photo. The camera position is also good to achieve a shallow depth of field.
1.Setting the exposure using the histogram: The way to tell your exposure is correct by consulting the histogram. Learn to read and make the necessary adjustments until it indicates a proper exposure.
2. Raw: Using Raw gives you the full access to capabilities of your camera. A Raw image file is an image sensor of a camera which contains minimally processed data in which a Raw file captures exactly what the sensor on your camera sees.
3.Selecting Focusing Points Manually: This will improve focusing accuracy and reduce chances of missing important shots. Its not always anticipate correctly.
4.Learn All AF Modes: Al- Servo AF mode won’t lock the focus; it will constantly refocus. Most cameras come with different autofocus modes like one – shot AF, and Al autofocus.
5.Aperture Priority: A aperture priority mode, camera will very expose settings depending on the aperture value you set. This is a great setting shooting portrait with a blurred background.
6.Shutter Priority: This shutter priority mode will work like aperture priority, in the sense that if it gives you complete control over shutter speed while making all the other settings automatically according to the selected value. This is a good setting for a situation where you don’t want your shutter speed to go over or under a specific value.
7.Control Motion Blur: The motion blur often comes from using a shutter speed that is to slow for holding the camera in your hand. Learn what the lowest speed is for you and stick to it for motion free images.
8. Manual White Balance: All digital cameras have a few white balances presents. They recommend learning to set white balance manually according to each lighting situation.
9.Drive Modes: There’s three metering modes in most cameras each a specific job. They have different names depending on cameras manufacturer but essentially, they behave the same.
10. ISO: You need to learn how to select the correct ISO value depending on the lighting conditions. Lowering the value are great when there is plenty of light to work.
11.Auto – ISO: It will help you shoot handheld. It will increase or decrease the value in order to allow you to shoot with shutter speed as fast enough for handheld operation.
12. Exposure Compensation: The camera will increase or decrease exposure depending on your need. It will influence exposure in increments.
13. Manual Exposure: This last stage of learning how to use your cameras settings will fully manually control. You can’t call yourself a real photographer until you learn to control every little setting on your camera.
The light seem to be natural. This photo is soft. The light is headed towards the middle. The shadow seems to be hands tryna create a bird. This photo creates a strong contrast. A shadow is a dark real image where light source is blocked by an opaque object. The hands are going vertical. I like this picture because it reminds me when my sister and I use to turn our flashlights on and she would to different animals with her hands and it create a shadow. The shadow is very strong. In this picture the darkness is surrounded by the light coming from its direction. The photo has a interesting shape and figure. I like how it could catch someone’s eyes just by seeing what the hands created.
