https://www.youtube.com/watch?v=j3IE81FHjSk Depth of field or DOF is the area of the frame in which objects seem sharp. So stay tuned, if you want to get more tips on how to sharpen image or how to make background blur with the help of manual camera settings!
What does depth of field depend on?
➤ The distance between the camera and the object:
The farther you are from the object you’re focusing on, the more the DOF increases. The closer you are, the smaller the DOF becomes. That’s why when taking pictures of nature, it’s quite hard to shoot out of focus.
➤ Aperture:
The wider the aperture, the smaller the depth of the field. And it doesn’t matter what camera you use. Canon, Nikon, Sony, or Lumix.... the aperture is always wider if you set smaller parameter values.
➤ Focal length of the lens:
The longer the focal length, the smaller the depth of field. That’s why shooting with Canon 135mm camera lenses provides a more blurry background than 35mm lenses do with the same camera settings.
Large depth of field is usually used for architecture photography, landscape photography, or family photography. In other words, a large DOF is perfect for situations when you need the entire frame to stay sharp. Small depth of field, on the other hand, works well with portraits, product photography, or food photography - that is, situations in which you need to keep the main object sharp while the background stays blurred.

Origins of the Idea 🌱
The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. 🧠
Challenges Faced 🤔
Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.
Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. 🔍
Creating Truly Random Links 🛠️
The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.
