What does the focal length in brackets mean on my photo?

When you see a focal length in brackets — like 64mm — that value comes directly from the EXIF metadata in your photo file. Specifically, we show the FocalLengthIn35mmFormat field when it’s available.

This is not something we calculate ourselves, and it doesn’t reflect how much you’ve cropped the image. It’s simply what your camera has embedded in the file as the full-frame equivalent focal length based on your gear and settings at the time of capture.

• If your camera includes a FocalLengthIn35mmFormat in the EXIF, we’ll show it in brackets.
• If it doesn’t, we’ll just display the native focal length (like 55mm) without a 35mm equivalent.
