What a dumb exam
My camera is on a tripod and I want a lot of detail in a landscape photo, so I set my aperture to F11. What should my shutter speed be?
1. 1/20
2. 1/80
3. 1/250
4. Who cares, as long as my EV = 0 5. Off
How the hell can you say without knowing the iso
What is the decision you must make before taking every photo?
1. Should I shoot with a wide or small aperture?
2. Do I want to capture motion or action?
3. Do I have enough light?
4. Am I capturing motion or depth? 2
Or macro, portrait, astronomy etc etc duh

Or this dumb question
Where ISO is the sensitivity to light...
1. Shutter Speed controls how much light is allowed through to the sensor.
2. ISO controls how much light is allowed through to the sensor.
3. Aperture controls how much light is allowd through to the sensor.
4. 1 and 3 5. 1, 2, and 3
Excusing the spelling mistake of the person who thought the dumb questions up the "LIGHT" would be a constant so the shutter speed would NOT control how much light hit the sensor but for "how long"
The ISO does NOT control how much light is "allowd" sheesh but adjusts the gain of the sensor

Or this
This shutter speed is the slowest you should consider for hand-held shooting of a still object
1. 1/60
2. 1/80
3. 1/125
4. 1/250
5. 1/500
In relation to "what" lens !, do you have IS/VR, tele or wide angle

Remembering your Exposure Values from film (and entirely applicable in digital, w/slight differences) and assuming ISO 100 for minimum sensor amp, the correct answer is:
Bright sunny day (assumption)
Exposure Value [EV] 13 properly exposed happens in bright sunlight using these settings: ISO 100 f/11 1/80s to obtain the quote/unquote 'standard exposure'. We must assume a Standard Exposure given no other parameters.
Since they give you 1/60s as a choice it can be assumed that the landscape is being exposed slightly before or after the sun is directly overhead, or is impeded slightly by clouds, since they gave you it was a landscape.

This sounds like a quiz which was taken from a film text originally and someone 'ported' it to survive in the digital world.
You have to remember that in film, the popular consumer available film ISO'a also lovingly referred to ASA ratings were 64, 100, and 400. You had to DIG, where I lived for example, for ASA200.
AE was the big deal, as in "WOW!!! my camera will figure out one third of the triangle for me...so effin' cool, dude, check this out..."
Today batteries in our camera are just...batteries.
Back then, the battery in the camera was something a lot of people forgot about..." Ah, crap, that damn battery died...where is it at?" while we ran to the photoshop and HOPED thye had it on the shelf and then cried bloody murder when it was a $8 purchase. $8 in gas let me get to work in my VW bug for like two weeks.
AutoFocus?? Image Stabilization??VR?? even today those have no influence on exposure, the same reciprocal of focal length was true way back when.
Breathe deep, and laugh at the test...it is funny to read the thing though...

Questions could have been written to be more easily understood. It seems as though the writer of the exam has only a cursory knowledge of the subject. I got a 60%! Should have gotten 100%. I used to teach this stuff to adults.

I took about 5 min and got a 70%...pretty sure I got the last answer wrong...

I got 70% according the them. I should have gotten all but one correct, arguably. The so called correct answers are really ignorant. For example, which ISO is best for a sunny cloudless day? They said ISO 200 is correct, when ISO 100 would be better. The handheld on is also ignorant, as it ignores lens length and VR capability. Changing EV by one stop without changing shutter speed can be achieved by both ISO and aperture.

They must be using a point and shoot :-)
