The progress of smartphones in recent years has been tremendous—especially the camera function of smartphones. The photo performance of cell phone cameras is more than enough for non-camera professionals. Because cell phone photography is becoming more and more intelligent, people can automatically adjust the parameters of the shot according to the scenery, objects, or people they are taking. In the iPhone album, select a photo, click the upper right corner to edit, and freely adjust the data parameters.

Next, I will teach you the iPhone camera’s functions and three iPhone camera colouring filter parameters.

iPhone’s camera features

Time-lapse: It automatically accelerates the video you shoot. When you shoot it, maybe it took a long time. When you play, the video is missing only a few seconds. When shooting, the red button is displayed at the bottom of the screen; every two rotations represent a video screen playback time of 1 second.

Slo-Mo: It is specifically used to shoot motion video footage. The speed of the picture taken is slower than the conventional. It is suitable for shooting scenes of people walking, fast movement, rain, and snow. This feature makes the scene more detailed.

Video: Normal recording constant speed video. No slow speed nor fast.

Photo: Normal photo taking. The top of the screen allows you to choose your favourite filter or photo size while taking a picture.

Portrait: This mimics the effect of a DSLR camera shot by defocusing the background and thus highlighting the foreground. In other words, portrait mode keeps the face of the person being photographed clear, while the environment generates a beautiful bokeh effect, thus highlighting the subject more. When shooting people with a cluttered background, we can use portrait mode to bokeh the environment so that the viewer’s attention falls on the people.

Pano: Take a large angle photo based on the yellow horizontal line in the middle of the screen. Simply put, you can use this mode to take pictures beyond 180 degrees.

Three types of colour mixing filters

Type 1: The almighty food filter (makes your photos look appetizing)

The disadvantage of the original: food shot out of grey colour, single colour.

Retouching ideas: to make the food look appetizing.

Suitable for the scene: this filter is a versatile colour palette; food photos can be used in this filter. For example, sushi, Chinese food, Korean food, fried chicken, hot pot, steak, etc.

Colour mixing parameters:

Exposure +15 (brighten the photo)

Brilliance +60 (increase the transparency of the photo)

Highlights -40 (to increase the colour, if you like the photo to have a luminous feeling, you can reduce more)

Shadows +20 (brightens dark areas)

Brightness +10 (brightens the photo as a whole)

Vibrance -10 (to make the colours not too intense)

Tint +15 (to make the photo warm)

Sharpness +70 (increases sharpness)

Type 2: suitable for the Victorian autumn filter

The disadvantage of the original: backlight shooting, the sky is too dark.

Retouching ideas: the photo needs to show the soft feeling of autumn sunlight through the leaves. Adjust the brightness of the overall picture to make the leaves transparent. Strengthen the colour saturation and warm tones.

Suitable for the scenes: autumn landscape, forest, outdoor.

Colour mixing parameters:

Exposure +20

Brilliance +80

Highlights -20

Shadows +20

Contrast -75

Brightness +20

Black Point -10

Saturation +65

Vibrance -35

Warmth +55

Tint +30

Sharpness +15

Definition +25

Noise reduction +11

Note: We can adjusted the picture specifically to your liking. The photo should not be too bright or too dark. We need to focus on the saturation of the colour grasp, not too strong. Try to keep the colours as close to nature as possible.

Type 3: Japanese style cartoon colour filter

The disadvantage of the original: the photo lacks a sense of colourful layers.

Retouching ideas: I believe that many people love to watch Japanese anime; this filter can turn the original photo into close to the feeling of anime. Make the photo look more colourful and contrasting. (This is what I took at a high-speed train station in China, it looks a lot like the Shinkansen of Japanese anime)

Suitable for the scenes: photos with proper sunlight. Simple picture.

Colour mixing parameters:

Brilliance +80

Highlights-70

Shadows +50

Contrast -10

Brightness +5

Vibrance +15

Sharpness +20

Note: High saturation and a pronounced bluish tint are very important. Do not make the photo too distorted while toning.

Formative & Summative Assessments

November 28, 2021 / / 1 Comment

In most courses, most teachers combine two types of assessment to check student learning outcomes. One is Formative Assessments, which are assessments conducted during the teaching and learning process to understand student learning and to identify problems in teaching and learning in a timely manner. Formative assessment is often conducted in the form of informal examinations or unit tests. It places more emphasis on the learning process and students’ experiences in learning; it emphasises human interaction and teacher-student communication. Another type of assessment is Summative Assessments, which are also a way of assessing students’ learning, but have a different focus from formative assessments. Summative assessment is the appropriate evaluation of the results achieved in the classroom. It refers to the evaluation of the effectiveness of teaching and learning at the end of the activity. It is the evaluation of the final outcome at the end of a unit, a module or a semester.

The difference between formative and summative assessment lies in the different timing and purpose of the assessment. Formative assessment is conducted in the middle of a lesson, semester, or academic year. Summative assessment is the assessment at the end of a lesson, semester or school year.
For the purpose of assessment, diagnostic assessment is to find out the student’s knowledge base and readiness, formative assessment is to identify problems in teaching and learning in a timely manner, and summative assessment is to improve the effectiveness of teaching and learning in the future.

VR and AR

November 19, 2021 / / 0 Comments

This week I am very happy that we learned about ar technology. I really like ar. on one hand, I like VR more in terms of gaming experience. on the other hand, AR is more practical in our real life.

First of all, the technology of VR and AR is different. It provides a completely artificial environment. Simply put, when you put on the VR glasses you see people, objects and scenery are all virtual. AR is an abbreviation for augmented reality. It provides a picture that combines the entirety of reality with some intelligent images. Apple’s official website, for example, offers AR images. We can see what Apple’s phone looks like around us through AR function. Although the AR function on Apple’s website is not done well enough, it can at least enhance my actual feeling of the phone. I really like to use the AR function to buy furniture. When my new house needs to be decorated, I use AR to pick out the right size and the furniture I like best.

Secondly, VR and AR are different in the way they can be used. With the current technology, you can only enter its virtual world through VR glasses. And AR has two methods of use. One way is to put on AR glasses, and the other way is to enter AR through the screen and camera of electronic products.

In short, I really like these two technologies. I hope they can develop better in the future.

Quizlet Blog 1.0

November 4, 2021 / / 1 Comment

Through last week’s blog, I found out that many students are using Quizlet, and I talked about the advantages of Quizlet and why I like it even though it is a passive learning software. Next, I want to improve my original blog by incorporating the multimedia teaching principles I learned in EDCI 337.

Firstly, I want to improve is the Dual-coding theory of Quizlet and my original blog. What we know is that Quizlet’s has only textual explanations of words, phrases, and sentences; it does not give any image memory and association with knowledge. dual-coding theory helps us to understand and remember knowledge better in learning by combining the functions of the left and right brain. If Quizlet can improve the two parts of words and explanations into words, explanations, and pictures, I believe it will provide more help to students who use it. In addition, In my original blog, only had some relevant screenshots and no details related to the Quizlet. So, I will enrich my content by making my pictures.

It is what the Quizlet looks like. It only has 2 parts of words. (Verbal Code)

The part 1 is the word I want to remember, “curtain”, and the part 2 is the Chinese meaning of the word. Now, I will add the third part: picture memory.

Now, whether it’s my blog or Quizlet, doesn’t it look richer and easier to understand? This is the benefit of combining Dual-coding theory.

Secondly , there is a video that will teach you how to use Quizlet:
