A shot of me with the fujifilm set to a lens length of 38 mm with 3 lights. In heinsight I look a little agressive but heh, at least it's different. 😅

Camera Setup

So I've been improving my camera setup to help with video recordings, livestreams, Zoom calls, etc.

So I wanted to make an animation of code being written in the minimap, so I set up VS Code so that it would write the minimap canvas to a PNG file every time there's a backspace (play that in reverse and you have typing out a file).

var fs = require('fs')
var curFrame = 0;
function saveCallback() {
    // Get the DataUrl from the Canvas
    const url = document.querySelectorAll('canvas')[1].toDataURL();

 // remove Base64 stuff from the Image
