我最喜欢在集市买东西，打比方说衣服，性价比超高。集市上的服装，默认收集民意，冬天为个舒适暖和，夏天图个凉快，多余的设计，一点儿没有。便宜没好货，未必对。明星走红毯穿的礼服倒是贵，但不冻着你，不绊着你，不叫设计。我有个建筑师朋友，在我的影响下，第一次拒绝了客户。对方就是暴发户心理，想要一堆花里胡哨的东西。要真有子儿，只当瞎玩玩；没几个钱还想瞎玩，趁早拉倒。豆腐渣工程都是这么来的。

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 :
However, it lacks a built-in display, so you can’t choose which images you want to print directly on the camera itself. This often results in more wasted shots, especially since image quality is so-so at best, even when compared to those of the Retro 3. Photos are nowhere near as clear as the Instax Mini 12’s, either, especially in areas that are either too bright or too dark.
