My next big photo op is roughly one year away. I am heading west with a few friends to attend the Reno airshow. As in Reno, Nevada. Wow, I have some work to do!
First, this takes me a bit out of my element. I like nice static subjects. If I miss it, I can go back. I'm not much for one and dones.
I've been looking at web sites for aviation photography and a few things I've learned. One is I'll need to go shopping for something more powerful than my 200mm lens. Doable.
I'll also need to be able to take shots at 1/2000. The guideline for taking photos of prop driven aircraft is 1/40 to 1/125. The blur of the prop makes the shot. But for jets and very distant shots with longer focal distances, the higher speeds are essential.
One option to achieving higher speeds is to open up the lens' F/stop. I'm real comfortable at F11. I'll go to F/8 if I need to but that's about my limit.
Another option is to increase the ISO. Being brought up in the 35mm days, 100, 400 and 800 are my familiar numbers. The advertising on my D7200 says I should be able to get up to 1600 without too much issue.
OK, let's find out.
I've seen a number of sites that demo ISO noise effects. Mostly the changes are in the area of color and definition, plus the introduction of 'noise'. I should be able to compensate for definition to keep away from a really soft look. I should be able to saturate as necessary for color. The noise? We'll have to see.
Now what I really need is a subject. And as luck would have it, the snowmobile races that I went to last year - were going on today. This is as close to air races as I'm going to get today.
To get where I want to go, I'm using Manual Mode. I have the lens set at F11 and the speed at 1/1000. I took a few evaluation shots and found that when shooting in the sunlight, 1/1250 painted a very nice histogram. With a year to prep, I have one data point.
Focal Length 27mm
(Just in case you missed it before.)
The JPG that Nikon created was OK. On the RAW image, which is the one above, all I did was let Photoshop add some depth and I added just a bit of green saturation for the grass.
First test passed. I think the image is fine. Next test - will the D90 do as well? (It's going out west too!)
