Proses pengubahan panjang lensa saat pengambilan gambar sering disebut dengan cropping atau zooming. Perubahan dari focal pendek ke focal yang lebih banyak disebut zooming in, yang akan mengakibatkan obyek nampak lebih besar (kesan dekat). Sedangkan perubahan dari focal panjang ke focal yang lebih pendek disebut zooming out, yang akan mengakibatkan obyek nampak lebih kecil (kesan jauh).
The process of changing the length of the lens when shooting is often referred to as cropping or zooming. Change of short focal to focal more called zooming in, which will result in the object appear larger (close impression). While the change of the focal length to the shorter focal called zooming out, which will result in objects appear smaller (much impression).
