I'm testing the different features of the camera. There's a built in DN filter. I think it's a real physical filter, cause when you activate it, you can see something moving on the lens.

I thought that it was used to reduce the light for taking long exposure photos, like waterfalls, o waves.

I've tried it in a during day, and I need to reduce the exposition time in order to avoid overexposition, not getting any special effect on movig water.
I'm doing something wrong?
Anyone has used it?

Thanks in advance.
 
From user guide
ND Filter (Internal ND Filter)

Using the ND filter allows the amount of light entering the camera to be reduced by about 1/8, the shutter speed to be slowed and the exposure to be decreased. This provides very effective shots of such scenes as flowing water and waterfalls.
Worthless in my opinion

Well I shouldn't say that as I only tried it once! It may have it's merits. I'll give it a try next time I shoot waterfalls this week.

altering any parameter settings or isit automated and are decisions/calculations made by the camera ?

The ND filter can be used when the camera is set to (Program Auto), (Shutter Speed Priority Shooting), (Aperture Priority Shooting) and (Manual Exposure Shooting).

I used the nd filter for this, it was still slightly over exposed so had to alter it a little but with out the built in filter would never have achieved it.



 
Thx to all...

I've already RTFM. What I wanted to know if someone had managed to use it and get good results.

I've tried it, but I didn't get the effect of the photo above. On a sunny day, the exposure time, even with DN filter activated, is too short to get the movement effect.

My intention was to take photos of the sea using this filter. I better try it late at the evening.

When in a Manual mode, you must activate it at Menu.

I think it's a real filter, not software processing. If you at the lens when activating it, you'll hear a low noise and you'll see something moving in front of it.
 
it's either on or off.

When using the ND filter for slower shutter speeds I find it easier using full manual settings and playing around with shutter speed and aperture to get the best exposure. It's better used on an overcast day so your not getting too many bright spots from the sunlight but you'll probably still need to take over exposed shots and correct them in Photoshop or something if you go for 1/2 second or slower. Without the Nd filter you'll just have a bright white screen! Mind in saying all that I'm pretty new to this game so I'm only going off what I've learnt so far, but it's like any other shot.....getting the right balance.
 
I have used it only for flowing water. I just put the camera in P mode but will put the iso at 100, close the aperature down as far as it will go and turn on the ND filter....ie let the least amount of light in to get the slowest shutter speed possible.

I think you will find that for some stange reason in P and S modes smallest aperture possible is f/6.3. In A and M modes you can go to f/8. Makes no sense to me.
 
If its exposure (too much) your concerned with then I'd not worry about the ND filter. Just shrink the aperture or select a faster shutter speed - or both. Manual mode is what you should be playing with. Just to get the hang of it so to speak.
