I'm going to the Alliance Air Show next week and I have a question that I didn't see posted.
I will be using a Canon T6i with the Canon 100-400 MK II lens.
What type of metering are you guys using? Spot? Partial? Evaluative? Center Weighted?
The show starts at 8am and the sun should be to my high-back.
This with evaluative. but passenger jets are pretty predictable. LOL
the sun was to the nose of the aircraft.
Personally it doesn't matter, I prefer using an external incident lightmeter and shooting manual exposure. You get far more reliable exposures that way. I use the free Android LightMeter app on my Samsung Note 3. I like it because it recreates the info as an old style analogue meter. I really like how is shows every possible shutter speed/aperture combination for the chosen ISO value. Accuracy of the app is absolutely fine for me in incident mode against both my 50D and my old backup/second body 20D. I believe the app is also available for the iPhone.
If I absolutely had to use the camera's metering I would use spot and meter of a substitute target, I tend to try to use an area of green grass or other mid toned surface. Still shooting in manual mode. You can use the palm of your hand as a target, but I struggle to do that when had holding a long telephoto lens. My arms are just not long enough for that.
At a show just to be on the safe side I will use the incident meter to get an exposure setting, and then use that to "calibrate" a setting for a close to mid tone area. That way if I think that a change in light levels has happened I can just point the camera at my calibrated surface, and reset the exposure quickly in situations where I don't have time to go back to the incident meter. The incident meter is best used between the different aircraft performances.
I usually shoot at about +1EV on the meter reading to allow for the fact that the aircraft are backlit. I'm normally trying to get a good exposure on the underside of the aircraft, so that I can bring out as much of the detail as possible. I'm not too worried if the specular highlights, like sun reflections are blown, they have no detail anyway. As long as you are shooting RAW you can pull the highlights way back in most modern conversion software. To that end I usually shoot in Faithful picture style, with the sharpening and contrast etc. pulled all the way to minimum. This gets the histogram, which is always based on the currently set processing parameters to be as close to the RAW image data as possible. It does make the in camera preview look a bit soft though.
