In the previous two posts on using the GND filters, I wrote about what is needed, what they look like and how they are actually attached to the lens. In this post I will try to explain how they are actually used. So, let’s have a look at my image “Being There” first and I then try to explain what I did there.
I took this image just before sunset with the last bit of the sun still being around the horizon. The dynamic range of the scene was naturally rather big and as almost always I used my filters to hold back the exposure on the sky. But how to decide, which filters to use? Here comes in the metering.
Of course the more you work with filters, the more you get a feeling which filters to use. When I’m in a hurry I start off immediately with a 2 or 3 stop filter and then check the histogram. But to be precise it’s still best though to do a quick meter reading. Since I have no external lightmeter yet, I proceed like this:
After that I switch back to AV or M mode and attach the filters and frame the shot. When I then take the image, I usually switch back to Evaluation Metering mode, and most of the time that works fine. In case of doubt, I do a meter reading from the foreground before attaching the filters and shoot manual then.
Which filters to choose is a little dependent on the scene. A scene with an uneven horizon, such as mountains or hills, tree tops etc. ideally requires graduated soft filters, whereas a straight horizon, like in this example, it’s better to use GND hard filters. (If these doesn’t mean anything to you, please check back on my previous post here).
In this particular image I used two GND hard filters with together 5 stops to compensate for the bright sky (Disclaimer: I took this image quiet a while ago but I think it was something like this) and moved them down around to the horizon, then focused manually (I usually do), checked the DOF preview and took the shot. Checked the histogram and bracketed a little and took another image. And that’s it. I tried to demonstrate how I place the filter in the following image: On my way home I already knew there was a nice image waiting for me on the memory card, which is a very good feeling to have. Of course the filters don’t have to be placed horizontally like in this image. On the image “Autumn Rocks” I placed a GND soft filter diagonally across the frame like you can see in the following image:
With filters it is possible to achieve amazing results and to get the shot in the camera, which is something that I prefer. There are of course situations where it’s more useful to blend multiple exposures together in Photoshop, or do a HDR. But for me, the use filters has improved my photography a lot. I will definitely invest in some more filters. This time though ND filters. But I think that should then complete my set.
