1. Panorama: Instead of doing a traditional horizontal movement, I moved in a circle, which reminded me of when we took a portable scanner to a 3D surface.
2. 3M3D: 3D scanning on my phone!
3. Measuring tool on my phone!

Lightpainting: Usually we use lightpainting to capture the path of light. Long exposure creates mesmerizing light trails, making it great for artistic representations of movement. When the object is still, lightpainting allows more details to be captured. When the object is moving, lightpainting will record the trace. The following are lightpainting pictures for 1 second exposure and 3 second exposure. I move my head while the exposure time.

Panorama: This technique usually is for capturing the full breadth of a scene or subject, like wide landscapes, cityscapes, or long horizontal objects. Since the panorama photo is a collage of series continuous captures of an object from different points or angles, we can use panorama technique to create photos with different perspective of a same object. The following are panorama pictures of a painting in Andy Warhol Museum. The first’s capture path is parallel moving with the object. The second’s capture path is changing the angle i stand.

Slowmo: Usually we use slowmo to record Fast-moving objects to reveal details that are invisible to the naked eye. Here I use it to record the process of “tried yawn-to-true yawn”. I want to see how our facial muscles work differently.

I plan on doing this activity again, but I first tried to document my tiny snow globe by my window. Its height is the size of my thumb, so it was difficult to get a crisp image of it as a close up photo. I first shook the globe and wanted to capture the movements of the snowflakes using time-lapse and slowmo.

(time-lapse)

(slow-mo)

I initially thought that slow motion would have a better image but I realize as I was shaking the snow globe that the way the flakes move is not that fast. Therefore, it felt more excruciatingly slow to do a slow motion.

Lastly, I did a 3d scan of the globe using Polycam.

Most details of the globe was well captured in the model but it had trouble understanding the “glass” and reflexive surfaces.

iNaturalist is a mobile app that uses image recognition technology to identify the plants and animals around you. I snapped a photo of two plants in my apartment, a basil plant and what I learned to be known as a Mother-In-Law’s Tongues! The app identified the plants and offered information about them.

Ghost Vision uses machine vision to detect human figures in real time providing skeletal data of the person in-view. It can even detect multiple people at once. I snapped a picture of myself in the mirror to try this out!

ZIG SIM uses data from a ton of different sensors in your phone to allow you to obtain a ton of different metrics. You can measure things like touch radius, pressure, mic level, gps, etc. Below are screenshots of me trying out the gravity and compass features!

我意识到我的猫睡觉时尾巴会摆动。所以我开始思考如何捕捉它。

首先，我家的猫咪在窗台上睡觉，我走近一看，它的眼睛几乎睁不开。今天我的拍摄对象是它的尾巴。下面这张图，就展示一下它那几乎是短腿的它，以及它那摇来摇去的尾巴。

我延时拍摄

我想知道我家猫咪睡觉时一分钟内尾巴摇了多少次。我拿起手机录了一分钟的视频。为了更快得到统计结果，我使用了缩时录像：

使用 capcut 软件，我将整个视频放大到 8 倍，我可以清楚地感觉到尾巴在摆动，甚至波动。但我的猫一直在睡觉（至少它假装在睡觉 🙂

在这一分钟里，他的尾巴摇了30多次，大约每秒0.5次。

II 慢动作

我想看猫咪摇尾巴的细节，所以我拍了一段0.2秒的猫咪剧烈摇尾巴的片段。我把镜头放慢了两次，每次慢0.1秒，这样我就能看到猫咪摇尾巴时每一根毛的方向。真的很酷。

III 狭缝扫描

如果把移动的碎片定格，再连在一起，会是什么样的感觉？我用silt-scan软件探索了这种可能性。静止的时候，图片左边的线是他的爪子，因为静止所以是直线，右边的线是他尾巴的轨迹。

因为抖动，线条时而急转，时而断落，时而轻盈，时而拥挤，你可以想象，如果一支画笔在移动的纸张上留下痕迹，大概就是这样的。

四、基于反射技术和捕获对象

猫咪是一个运动的物体，相比这三种基于手机的扩展捕捉技术，Timelapse 可以长时间记录所有内容，而 Slow Mo 和 Slitscan 可以捕捉肉眼不易察觉的细节，而这些细节往往非常有趣。两者相比，Slowmo 反映的内容更加真实，Slitscan 则有一定的创意在里面，最终 Slitscan 得到的是基于现实的再创作。

我喜欢silt-scan带来的不确定性，通过光学成像，猫的尾巴仿佛是一把画笔，画笔自由摇曳，在我的手机上留下即兴的一笔，而这一切都是他无意识的创作。
