Zoom lenses foreshorten distance between subjects.
eg This picture of two aircraft in the stack for Heathrow
The DHL is at FL90 and the JAL at FL100.
(For non-pilots/non-ATC: 1000' vertical separation.)
There is also 1000' vertical separation between these two:

does look really close though. for aviators & non-aviators FL90 is not a flight level. flight levels do not start until 10,000 ft FL100.

That's not correct re the UK - where the picture referring to Flight Levels was taken.

Seen this photo? The effect is called "foreshortening", where because of the distance from the object and the amount of zoom needed to get the helicopter that big in the frame, it makes it look like objects in the foreground are directly beneath the object in the frame. In both these photos there is something else that is contributing to the illusion - in the hover barge picture, the reflection in the water makes you initially think the helicopter is right above it, and in the Cobra picture the shadow on the ground does the same. Given the angle of flight of the Cobra, it would have already hit the ground with the rotors. Have a close look at the shadow, at the offset of the skid supports, that will tell you the angle of the sun and therefore you can work out roughly how far up it actually was.

Possibly the wrong forum to ask but for us non airline pilots is it really that common to be that close? 1000' seems awfully close.

There's more information about the Columbia Vertol on this thread -
600,000 hours
This sequence illustrates the effect of zoom lenses very well.
Watch the focal length (bottom corner) changing.
I think the most accurate view is at 50mm, but my knowledge of the technical aspects of photography is very limited.
(Apologies for the advert embedded in the picture. Hope it's OK just this once.)

Only half a speed-brake

1000 ft is awfully close horizontaly, but it is the vertical separation, aircraft use it to fly on different layers called levels. Horizontal nubers are MUCH greater.
In US, the transition altitude is 18000, in Europe usually much lower. In London airspace, FL 90 is a FLIGHT level, in Amsterdam FL 40 IS a flight level. Airspace design.

Im not a chopper pilot but get to use them regularly during floods.
Have been enjoying this thread so thought I'd post.
Apologies for the lack of technique but we were on a mission.

Okay, due to popular demand (okay, one person asked), here are some shots of mine with full-size download options. Apologies if you've seen them before.

By the way, the two guys you can see reflected on the helmet are the pilot and engineer. In the official Defence Media picture that appeared in several magazines (which is better than my picture I must admit), you can see three people reflected in the helmet, one of them in a suit - that was me showing the pilot and engineer the picture I'd just taken.

Gothenburg´s ambulance helicopter
Seen leaving medical crew on a pier in the archipelago - the pier was to small to house the S76 helicopter.
The helicopter is based at Säve airport ( South Western Sweden) and takes off on approx 1600 calls a year.

I read all 101 pages of this topic and I loved it verry much!
Unfortunatly I don't fly but I want to go for my PPL soon
Here some photo's that I've made (almost) all in the Netherlands:
Appache
Cougar
A duck fly by...
Another one with photo's of me, there will be verry much posts from me, because I've got verry much pictures, but I'm only allowed to post 15 pictures in 1 reply
Cougar
A helicopter of the fire brigade in Loulé, Portugal
World Harbour Days, Rotterdam, The Netherlands
Christoph Europa 2 D-HHTS EC135 on Rotterdam Airport, The Netherlands
Some helicopters at the Aviodrome, Lelystad Airport, The Netherlands
That's it! A thing I really want to do is take some air-to-air pic's of helicopters, but it's so expensive to fly in a helicopter

I'm sorry, I see now that it are too many pictures. It's because of I were in a hurry when I selected them and also because this is a selection of ALL my helicopter photo's and I can tell you, I have got verry much helicopter pic's! But next time I'll look if I can get it in one post...

No worries mate, you're obviously enthusiastic about it - if I posted all my pictures I'd probably fill all 100+ pages on this thread! The only thing about cramming lots of pictures per post (like I did in my last one ) is that it makes the page get really long and people on slow dialup connections get a bit tired of waiting for all the pictures to download.
Keep them coming though, we wouldn't be here if we weren't a little more than slightly obsessed with rotorcraft!
Cheers!
