For an instant camera, image quality is also better than most of the other cameras I tested, producing relatively true-to-life photos. Most struggle to capture low-light conditions well, and this one is no exception, but the built-in flash helps. Fujifilm claims the Mini 12 optimizes image quality in both bright and dark environments better than its predecessor, but I didn’t notice much of a difference. The flash — which you can’t disable — is also still overpowering in some instances, resulting in a few overexposed images. Photos actually seemed a little darker and less vivid than before, but selfies captured my features and skin tone more accurately, thanks in part to the small front-facing mirror. The updated lens design also lets you twist into Close-Up Mode to zoom slightly and activate the Parallax Correction features for a more aligned photo. It’s a fun, point-and-shoot-style feature, though aligning photos still takes some practice (as well as some composition guidance from the manual).
