In product photography, what does the term 'diffraction limit' refer to when selecting an aperture?
Answer: The point where smaller apertures cause light to bend around the diaphragm blades, reducing sharpness
At very small apertures, light diffracts around the aperture blades, softening the image even as depth of field increases.
A product photographer is using a 100mm macro lens at f/2.8 and 1/125s. To achieve f/8 while keeping the same exposure, what new shutter speed is needed if ISO remains unchanged?
Answer: 1/15s
Moving from f/2.8 to f/8 is a 3-stop reduction in light, requiring a 3-stop slower shutter speed from 1/125s to 1/15s.
Why is Auto ISO generally discouraged for controlled studio product photography?
Answer: It may introduce unnecessary noise by selecting a higher ISO than needed
In a controlled lighting environment, the photographer knows the exact light output and can set the lowest possible ISO manually for optimal quality.
When using flash for product photography, which element of the exposure triangle primarily controls the brightness of the ambient background?
Answer: Shutter speed
Shutter speed controls how much continuous ambient light is recorded, while flash exposure is primarily governed by aperture and flash power.
A photographer shooting glassware needs to balance sharp focus with pleasing bokeh on reflections. Which exposure triangle approach works best?
Answer: Use a moderate aperture like f/8 and focus stack multiple shots
Focus stacking at f/8 combines the lens's sharpest aperture with full depth coverage, while naturally softening distant reflections between stacked frames.
What is the reciprocal rule and how does it apply when hand-holding a camera for product shots with a 60mm macro lens?
Answer: The minimum shutter speed should be 1/60s or faster to avoid camera shake
The reciprocal rule states that hand-held shutter speed should be at least 1 over the focal length, so a 60mm lens needs 1/60s or faster.
