Using ND filters

[m3lv1nh0]

Hi Guys,

Just tried using a GND filter to capture our merlion. I managed to extend the shutter speed to 6 secs so that the water flow from the merlion looks silky. However, the sky turns purple due to the filter. How do I overcome that? Thanks

Here's the pic:

Lovely photo!
From what I have seen this is characteristic of GND filters because of the gradiated effect on the exposure. In the "darker" region of the filter you will get a more normal exposure of the sky (hence the blue), and the "lighter" transition phase of the filter will gradually over-expose the sky making it so light. Appart from layering in photoshop, I'm not sure what you can do here. Did you use a hard or soft GND?

yea I believe it's because it is a Graduated ND, meaning the shade of the filter coat changes across the filter gradually. maybe you could try ordinary ND filters?

You can add a grad blue filter. Or you can cool your color temp.

BTW, you may want to get lower speeds so that the water surface bcomes glassy. Like 15 sec.
