Long exposure picture overexposed

[reddusk41213]

Hi

I am going to shoot waterfalls tomorrow and i was hoping to do some long exposure photos to get the milky water effect.

I have followed the instructions in 1 video on youtube.

https://www.youtube.com/watch?v=HKJTc2YpC0c

Photo Mode and in Night Photo Mode.

2 second shutter speed. (There is no shorter speed in Night Photo Mode).

Iso Min and Max both on 100.

There is no way to change Exposure setting in NFM.

And i have a ND32 filter on.

And all i get is a white image .

Why is this when as far as i know i am identical in every respect?

I have followed another guys instructions and his are practically the same in regard to ISO and ND32 Filter.

However his shutter speed is Auto. This seems better as i don't get a white image, but i won't know what the images will look like until i get to the falls and it could be a wasted trip. Obviously it's a very short shutter speed so i can't imagine i'll get the milky effect. 

One thing i do notice is in his video he changes the EV comp down to -2, but on my HB7 it says N/A and i cannot adjust it.

Why can't i change the Exp comp and he can?

Hi @reddusk41213,

EV Comp isn't available on Night Photo mode. The white image indicates that, since this was taken in broad daylight, the environment wasn't dark enough and there was too much light that came in due to the long shutter speed. You may need to get a more darker ND filter in order to achieve the silky smooth water effect on your photo if you'll be using Night Photo mode. Here's a thread that I found where users discussed how to do long exposures in broad daylight. See if the setup will work for you as well.

Kind Regards,

Ann

you need a lot darker than a ND32 to use nightlapse during the day. I use an ND1000 & can only do 5seconds exposures

[reddusk41213]

Can you get nd1000 for GoPro?

@reddusk41213, you may be able to get this third party accessory from other online retailers.

yes, my picture above was doine with a Hero 4 Black. I use an adaptor & use a 52mm filter

Actually guys I stacked my ndfilters.
32+16+8 for 2 second exposures.
32+16+8+4 for 5 second exposures and come out great.

come on, we need pictures

I stacked my ND1000 & ND8 & managed a 30second exposure. Only a test but the flags are quite funky
