Did you use any filters?
Protective UV.
Is this just one shot?
Yes.
Where were you positioned?
The back of a Toyota Land-cruiser (pop-top) traveling about 50KPH over unimproved dirt road.
I made quite of few images similar to this. Some were made from a non-moving Land-cruiser. Tri/monopods are useless in this environment. Wide, normal, a short-tele shots are handheld. For long tele shots (400mm) I use a Kinesis Safari-Sack filled with whatever you can get locally (corn, rice, etc.). As most people in the cruiser are interested in game photography, setting up landscape shots just isn't practical. My most successful were taken "on the run" as this one was.
The truck motion in this shot was from right to left. I had spotted the large Acacia and began making exposures as it began to"pass by"and approach the distant mountain range. With all the motion, you can't use the viewfinder. If you do, there is way too much camera motion. The secret is to use a focal length a little shorter than you than you want (cropping allowance) and hold the camera away from you. The idea is to let the camera act as a seismic mass suspended on soft springs (your arms). This stabilizes it well enough for in-body or lens stabilization to take care of the rest. You would be amazed at how well this works.
Asher, is this what you wanted? If not, ask for more.
