Is there a translation for ISO, file formats (i.e. JPEG, RAW), depth of field?
Generally for ISO people just say “ee-so”– when I had to explain it to students, I’d describe it as “sensitividad del sensor” or “velocidad de la cinta” (the second definition there got very confusing with shutter speed, and is not quite accurate besides, so I generally stick with the first). File formats don’t get translated, they just get hispanicized in their pronunciation, or the letters read off in Spanish (jota-pey-ey-hay, for example). Depth of field is “profundidad del campo”, shallow depth of field is “poca profundidad del campo”. Hope that helps!
Hola,
How do you say ‘the shot’ in Spanish? El disparo?
Could you say “tuvemos demaciado prisa cuando haciendo el disparo”?
Hola Simon, I would translate “the shot” as “la toma”– since to shoot a picture is “tomar una foto”. I would translate the second sentence as “tuvimos demasiado prisa cuando hicimos la toma” or “cuando tomamos la foto”. Hope that helps!
