So last time I talked about the SRB-Photographic ND1000, and I have got to say that I really love this filter. It is a clean image producer and is very neutral in terms of white balance. However depending upon the lighting environment of the scene (i.e. cloudy and overcast, or pure blue skies) the white balance will changed slightly. When I first started to shoot with this filter it was early spring and very overcast out so the sky acted as a massive soft box for me. There was very little shadows around me and I was able to shoot with out worrying about the white balance. However as I recently discovered while up in Canada shooting an old docking wharf, that under perfect blue sky conditions and harsh sunlight, the white balance took on a bit of a warm shift. Now this is not a issue because I shoot RAW format at all times and it's incredibly simple to correct the WB in Lightroom. I also said before that many other ND filters will change the white balance of an image as well. This is true and today what I have for you is a wonderful comparison between the Hoya ND400 and my SRB ND1000.
I was contacted by a fellow photographer and friend Brian ( check out his work: www.500px.com/BrianGreenberg ) he wanted me to show everyone what his Hoya ND400 could do in terms of Neutrality. Obviously I said sure send me the photo. And here it is right out of camera this is what Brian got:
The original file was a bit under exposed so I brightened it up slightly so that the detail can come through. What you can see from the RAW file is that the Hoya Filter produced a colder white balance. However some of this might be due to the time of day and setting where he shot this photo. Brian told me that this was taken around sunset in early spring. I love that the detail and sharpness of the image is retained with Hoya filter which means that the optical clarity of this piece of glass is top notch.
Now let's take a look at what comes out of camera for my SRB ND1000:
So here we have my RAW file. This image like I described before is slightly on the warm white balance. The reasoning for this is due to the harsh mid day sunlight. You can see that there was not a cloud to be seen and the shadows are very harsh. However the image is still a 20second long exposure. This file also is very simple to fix in Lightroom with some white balance correction.
Here are what we both did with the individual files in post process:
