Final answer:
Option 3: Photo spot film cameras use a more advanced process that potentially requires reduced dosage and provides superior image quality compared to conventional film cassettes, due to advancements in lens and filter technology.
Step-by-step explanation:
Images produced by photo spot film cameras differ significantly from those taken with conventional film cassettes.
Firstly, the images created by silver reduced from radiation-sensitive compounds in film emulsion show that older photographic techniques had limitations in terms of efficiency, as mentioned earlier in the context of astronomical photographs. Only a small fraction of light (around 1%) that hits the film contributes to the actual image formation.
Secondly, the photo spot film cameras likely use a more efficient process, potentially reducing the dose needed to create an image when compared to conventional film cameras. Technologies, such as the one used in Brownie Cameras, made picture taking accessible and simple for the average person, indicative of advancements in usability and possibly dosage efficiency.
Lastly, whereas earlier film cameras like the Brownies had meniscus lenses, modern digital cameras now have several lenses along with red, blue, and green filters, leading to enhanced image quality with minimal aberration and accurate color reproduction. This suggests that photo spot film cameras could very well exhibit superior image quality in comparison to older conventional film cameras that used simpler lenses.
