I have been going through my hard drives and I found a bunch of pictures from my Pacific Northwest trip last summer. I shot a lot of video with the Canon 5dmk2, but I also snapped some photographs.
Most of these were taken just off the dirt roads. If you look closely, you can see all the dust that has settled on the forest from all the traffic. That is a real problem.
I used a flash with a few of these to light up my subjects. I did not use any filters and I used mostly my 16-35mm f2.8 lens. You will see some macro shots taken with the Canon 65mm f2.8 macro lens. I love that lens and spent a long time with a banana slug up and personal.
