Of course, the question:


Quote:If a combination of f-16 at 1/30th of a second yields the correct exposure what effect will be seen by increasing the aperture to f-8 ?


Has the wrong answer if your camera is in aperture priority mode Wink

Oh, and 10/10 btw.

I couldn't answer any of them because there is a word I don't recognise: f.i.l.m.

As far as I can work it out it refers to some sort of photoshop effect that puts lots of noise (though they call it grain) on your pictures.

Fran - think of the example your setting the wee ones Wink. Btw 9/10 (made a silly mistake on Q3 - went the wrong way - must be tired).

Night night....

10/10, although it's pretty much the same question asked in ten different ways.

Here's a slightly harder one, taken from a real-life situation, and slightly exaggerated... Smile:

You are using a fully manual rangefinder camera, loaded with 400 ISO film. You're also using a flash on camera that also only works in manual mode with this camera, but you can manually reduce the flash as far as 1/128th power if you want to. The flash has a guide number of 14 at 100 ISO, expressed in metres. Your main subject you want to illuminate with it is 9 feet away. You want to balance ambient light in the background at -1EV, while flash will be exposed at -0.5 EV to get a nice subtle effect. Your camera meter is of course not a through-the-lens meter and is unfortunately partially blocked by the flashgun and gives a constant under-reading of 4.5 stops.

Oh, and you have a gel filter over the flash which reduces flash exposure by 2/3rds of a stop, and a blue filter on the lens which reduces overall exposure by half a stop.

Your in-camera meter is for some wierd reason jammed on ISO 1600 and it tells you to expose the ambient light as 1000th sec @ f8.

You would like to use as wide an aperture as possible. The lens has a maximum aperture of f2. What power setting should you put the flash to, and what aperture and shutter speed should you set? Smile Smile Smile

Eeeeerrr, get backup camera from boot of car (which also has wireless flash capabilities), job done!

Apart from the fact that the meter wasn't jammed on ISO 1600, the rest of it was exactly the situation I had recently when taking pics with my Mamiya...

And I didn't have a bit of paper and a pen... Sad

Strangely the images came out perfectly exposed, so all my mistakes must have cancelled each other out... Smile Smile Smile

But if anyone actually knows the answer, I'd be grateful to know what it was, so that I can repeat it next time...
