The Zoom Feature on the iPhone
The newer iPhones such as the iPhone 13 and 14 have a feature where you can zoom in and out when taking photos in the mm scale similar to how an actual camera operates. I recently started taking photos as a hobby, and for sunsets or any nature photography, this feature has been the difference between a good photo and a spectacular photo.
0.5 mm:

With this zoom feature, the camera actually zooms out a little further than what you are seeing. The camera lens starts to become more of a fisheye camera lens, giving the sky a more rounded, spherical perspective and adding to the depth. This also allows the camera to capture a greater view from the sides, and makes the photo look less flat.

This zoom feature is also great for one point perspective or creating vantage points in your photo. Similar to how you need a vantage point when drawing in perspective in art, in photography the lens and mm zoom can be used to create a vantage point where the eyes have a clear direction to follow.
0 mm:

Above is a photo using 0mm or not adjusting the camera lens at all. For sunsets or nature photography, it can be easy to achieve a nice photo by positioning the camera correctly and choosing a subject of interest and adjusting whether you are capturing the photo from the center or the side. While the photo above is great, it does have a more flat or less dimension look to it because the effect of a fish eye lens or rounded effect is no longer there. The sun in this case serves as a natural vantage point but does not have optimal depth to demonstrate the true distance of the sun.
3 mm:

Going to the max zoom of 3mm, this is where the resolution of the photo starts to significantly decrease and there is more noise in the photo. In this case the subject matter needs to be carefully chosen. Otherwise the photo even in iPhones camera in 4K or max quality still looks pixelated and blurry. The subject matter in this case, has lost its dimensionality. And the sun no longer serves as a vantage point.
Many people don’t know of the power of zoom, and may be surprised how easy it is to capture great photos with low effort and a good phone camera.
