im looking to take some long exposures in the day.

whats the best way to overcome overexposure with something like a 20 sec exposure in clear daylight???


thanks in advance

:wave:
 
you will be wanting Neutral Density filters, they are like sunglasses for cameras. Graduated ones are darkn at the top gradually changing to clear at the bottom
 
Can you overcome it?

I'd guess using the smallest aperture you can manage, on the lowest ISO possible, with as much exposure compensation as you can possibly dial in and use dark filters......in fact the exact opposite to what you would do for night exposures..............or am I completely barking up the wrong tree here??:cuckoo:
 
i dunno, i was thinking of the idea of taking a shot of my loval high street, it has quite a nice backdrop, taking it from the top of the high street looking down toward the view, having the people all motion blurred to give the effect of them rushing about and keep the back drop nicely in focus to give an efect of times past and pimes present sort of thing...

if you know what i mean
 
go for an aperture setting of at least 3 quarters of the way to the minumum (not too far as you'll encounter IQ issues), ISO as low as possible (50 if you can) and slap on an ND8 or so.

Dont have an example to hand at work, but experiment with that combo as see where it gets you :)
 
i dont have an ND filter yet, so cant play too much,, can put a pair of sunglassed infront though ;)

i done that before on a sunset capture
 
Basically anything to reduce the light hitting the sensor.

iso 100, f16 (much more and diffraction robs you from sharpness), nd8 filter, circular poloriser, etc.

Sunglasses would work but they might tint the picture, ND filters are neutral in colours so they dont introduce any sort of tints.
 
For waht you describe 20 seconds is well, too long.

More like 3-5 seconds maximum would do it. At 20 seconds the streets will look empty (Unless it is really busy)

You caould always do it in the las hour before dusk as light levels drop too, that would help
 
Two polarisers working 'against' each other ..... + ..... what everybody else has said! :)
 
Try getting at least one subject to stand perfectly still in the middle of the frame staring right at the camera - looks well spooky. 4-5 seconds should do it unless you want the streets looking totally empty.
 
Sounds interesting, do let us know your findings with this little experiment! Maybe you can even write a Tutorial/Guide on daylight long exposures! :)
 
Have you considered that if you pick the right time of day at dusk while the streets are still busy that although it will seem darkish in the street the picture from the long exposure will still look like it was day light.
