Trying to learn AI. Is upscaling only required in AI? If I create a design at full desired size, 300dpi, when I upscale it some elements may be more defined, but at the expense of color saturation being muted/a bit blurred; and, the file size increased. Yet when I watch tutorials for creating with AI apps, the same is done, the images look great when upscaled (even if they are designed at finished size and resolution). Suggestions would be greatly appreciated. Thanks
