Aperture Priority

Hi,

had a quick scan on the search for this often asked for bit of advice and exactly what is Aperture Priority:

Perhaps this will help a little; and do a little to explain Shutter Priority!

Thanks man. I am using Programmed auto (P), where the cam was controlling Apeture and shutter speed, i am controlling exposure/wb/iso/focus. I would use Apature priority as its a natural progression into learning my camera, however... I'm not 100% sure what it controlls. I've just had a play with it, am i right in saying that if i wanted to take a photo at night of a roadway and wanted red streaks of brake light through the picture i would use a high apature?

If you could give me a little more on it or a link to read that would be great! :)

Hi,

Use a tripod and experiment a little with shutter speed. You need a slower speed to get the streaks. Simply keeping the ISO to 100 will keep the speed low as it is so dark. Equally if you use an aperture of F16 then it will get really slow and show the longer streaks etc.

Try experimenting with the camera. Keep the ISO to 100 and then try at F4, F5.6, F8, F16. Review the images and see what the exposure looks like.

You could also use full manual or the "B" setting - but lets try the above first!
