Pronghorn are the Fasted Land Animal in North America. Nothing else even comes close. They developed these skills/anatomy as a result of learning to avoid predation. It seems there used to be some pretty fast Lions, tigers and other cats living in these hills. Those predators were obviously prolific during the last Ice Ace and before here in the Wyoming/Montana borderlands. The most most recent continental Ice sheet (5 glaciations in the last 500,000 years) stopped it’s advance about 20 miles up into Montana from my perspective here on the Bliss DInosaur Ranch. There were LOTS of critters hanging out below the glaciers.
This was captured back in late August when there was some tussling within the local herd. (see how green in August !)
Currently in Mid-winter, Pronghorn have all migrated 20 miles to the south. The Thunderbasin National Grasslands consists of a huge area of unpopulated ground. Thousands of Pronghorn head there in the winter. I drove through there about a week before this posts. I do have some good Pronghorn BIG herd photos from in the grasslands to finish. . My turn around time from taking a photo, then getting it posted is slightly over a week. That is unless I push one into the “line” ahead of others. It’s all telephoto work down in the grasslands. Nothing is close usually and there is only one road through the area that I’ve ever traveled. Vehicular traffic is limited to the main road. Forbidden on the grasslands, big fines for going off road. . The national reserve has hundreds of square miles incorporated.
Pretty much the only large creatures to winter over up here on the remote borderland ridges, are cattle and mule deer. The WhiteTail move down to more reliable water even though we supply it. They tend to be in the valleys for the season not up here.
“Pronghorn Bucks Rutting in the Backcountry” is a wonderful capture from a quality Game Trail Camera. I maintain a network of 26 cameras over about 5.5 square miles of both Montana and Wyoming backcountry as our ranch spans the border.
The Pronghorn were rutting in early October and this is just after the Oct 1 snow melted. Freezing nights already many times. Apparently the Pronghorn like it cool :).
Getting this close to fighting pronghorn would be difficult to do even with long telephotos. This particular game trail camera has performed well but each photo has it’s issues and takes me maybe 1/2 an hour every time I finish one just to get rid of the cheap camera problems in the digital darkroom.
To freeze a Dragonfly in Time and Space, you need to be patient and persistent. You also need to understand that dreaded M for Manual on the top of your camera. A cell phone isn’t going to do this, a DSLR on anything but manual has no chance either. Sooooo, here’s the trick… (catching a fly in between 2 chops sticks is easier) 😂
Photographers notes: This is an 800mm telephoto in direct bright sun (requirement) with your f stop on that long telephoto being f22 ish for a longer depth of focus field. He had to fly into a little zone about an inch thick at 15 feet away (minimum focal distance for my 800). That lens acts like a macro at 15 feet. IT is on a Sony Alpha 7RII giving me 70meg raw files or 40 meg .jpgs depending on what I tell it to do.
So I’m following a moving dragon fly and trying to catch him in an inch wide zone, and almost fill the frame at the same time. (this is a full sized image not a crop except for the sides of the formerly landscape aspect). I’ve never used autofocus, I don’t think it would work on this anyway. I set up a zone and let the dragon fly…fly into it. Machine gun clicks at 10 frames per second.
I digress, the faster shutter speed (which sucks up light) has to be fast fast fast at least 1/2000th of a second or more to freeze wings.. I was about 1/1500th here… Just a TAD too slow and a compromise to get more light… . Faster shutter = less light and your already loosing light from the f22 adjustment). You give up light for focal depth and fast shutter…. You have to compensate somehow….. (only three things you really can adjust on a camera , ISO, fstop/aperture size and shutter speed)
So that leaves ISO (camera sensitivity) to balance your image and gain that light back…. Less is better when it comes to ISO since too much will make your image grainy. Note how fine the grain is on this image. IT’s the last priority though because it lets you get the shot which is an important thing lolol..
