Instead of perturbing each pixel in the input image at random, we can choose to dither by a predetermined amount depending on the pixel’s position in the image. This can be achieved using a threshold map; a small, fixed-size matrix where each entry tells us the amount by which to perturb the input value , producing the dithered value . This matrix is tiled across the input image and sampled for every pixel during the dithering process. The following describes a dithering function for a 4×4 matrix given the pixel raster coordinates :
Thanks to the added level of customization, I was able to capture higher-quality photos that looked truer to life than those from the Instax Mini 12, Mini 41, and Mini Evo. Granted, the Mini 99 is an analog camera, not a hybrid like the Evo, so you shouldn’t buy it if you also want to print smartphone photos. The newer model is also less user-friendly than the Mini 12 and Mini 41, so I wouldn’t recommend it for young children. Still, for an advanced analog instant camera, it’s relatively easy to set up and use, rendering it as much fun for budding photographers as more experienced shooters.
