photographic objectives of the shoot and how the images are going

most circumstances, nowadays, professional digital format will be

film. Also, the convenience of using digital, with the benefits
of instant feedback of the shots to check composition and exposure
and the flexibility of taking RAW images etc, usually makes digital

exhibition panels or large roadside posters, medium or larger film
formats are considered by some photographers to still possibly have
