How Do You Take This Kind Of Ground To Air Photo?

Tue Jun 29, 2010 5:30 pm

I live where the planes are at cruising altitude leaving and arriving in Ohare, and some cross country flights go overhead. I was wondering how you take these kind of shots from the ground. http://www.airliners.net/photo/Qantas/Boeing-747-438/1729381/L/ What kind of equipment do you need? Is it readily available? Is it expensive? Is there an alternative way to see planes closeup at 35,000 feet? Thanks.

I believe he uses some type of telescope...

Did you read the remarks for the photo? It says right there

"400D + 1200mm telescope + 2x Barlow lens."

Also helps if you have super clean atmosphere..in New York I figure about 5 days a year, you get that quality. No matter how clear it is in the Northeast, when you go aloft their is always some layer of crap. Just enough to rob the extra quality you need as demonstrated in the above shot...nice photo!

Some guys from Poland are using 8" or 10" Synta 1200mm telescope along with dSLR. Take a look at extremespotting.com. A lot of pictures like this are there. Also the sky over northern Europe is specific (i was trying to take a RNAV shot with my 400mm lens in Poland and in USA so I know the difference) and you can get it dark like on that shot. Aperture value of lens is f/8 or f/10 and it is constant. Andrzej Kostrzewa is a master of shots like this.
On tha site you can find also shots of ISS

What I don't understand is why the sky is so black? Does it look like that through the telescope?

I took similar shots without telescope, and the sky appeared blue until I hit the 'Auto Levels' in the Photoshop. After that the sky became black like in this picture.

I suspect if you look at the histogram there's a fair bit of room at both ends of the scale. Between the air quality and the camera's dynamic range, it won't capture that much contrast, hence setting an appropriate black point means you get that extreme effect. Without it, the image would look very pale / cloudy, for want of a better description.

I think these kind of shots are cool, but they also look enrealistic due to the black sky. I mean we have colour rejections if there is a tint in the sky, or if the fuselage has an orange tone from airport light, but turning the sky black is OK?

Quoting sulman (Reply 6):

Wouldn't such extreme effect produced in Photoshop lead to 'editing' rejection in any other case?

Quoting sulman (Reply 6):

But maybe more realistic?

It would be interesting to have a look at this image before any editing, straight out of the camera.

Might be a polarizer filter, or it might just be the exposure. Most of the time when I look up, the planes I see at cruising altitude are blindingly white. The sky probably had to be black in order to get a correct exposure for the plane.

I agree! I'm the one that took this shot http://www.airliners.net/photo/Ethio...d=0f56f4601a346ab58689495e7f6ade22 so i'm a little bit concerned about telescopes and so on...actually i'm working on a telescope for ESA. Well...the black sky is done just to have more contrast, no polariser, nothing! the sky is blue and not black so if you're not able to capture it as blue why convert it to black?
I just don't get the point of the screeners concerning this   they find unvisible problems in normal photos and then they accept this kind of photos with black sky.
And btw you can see from other photos of the same photographer that the sky is blue...

I agree,if we have natural light like theirs then it should get accepted and for the tint it also should, for the smog in some areas (i.e. LA, NYC, etc.) limit people to their local airport( which may not be spotter friendly)instead of their back yard!
