Paul Boddie: "so that commercial planes can eventually travel at much higher speeds"
Although this is valuable work, one cannot help feeling that the legislative barriers are greater than the technical ones, at least until some corporate contributor to various lawmakers' re-election campaigns has a product ready that they want to sell.
The problem is not only the overpressure but also the exhaust effluent (NOx) that does not wash out in the upper atmosphere....above 60k ft....same for the space rockets....does us no good at all.
ray tracer: Ah nostalgia! Student days taking schlieren images of wedge profiles in a shock tube, then off to the darkroom to process our 35mm film.
yes, did the same in the '60s ..... Department of the Mechanics of Fluids at Manchester. Happy Days...read all about it in Liepmann & Roshko's "Elements of Gasdynamics"
iAPX: I would like to see people in the leica lens group when they read that, with such a low price! Lol!
I have Leica and M43 and they complement each other very nicely, especially as relatively compact travel cameras. I have the 21mm F1.4 Summilux which is a very fine lens on the Leica M, even though it is a bit pricey. What is nice about the Voigtlander series (have the 25mm) is the close focus capability...that is very attractive. Would like to see some photos taken with it.
I have been to the exhibition twice...not on the computer but at the Grant Bradley in Bristol. It is a wonderful (free) exhibition where you can take your time and learn. Not everything was particularly to my taste but that is not unexpected...but you can still learn processing technique....or composition...or both and more. The great thing about the exhibition in real life is that you are limited to the Mk.1 eyeball for resolution...so no pixel peeping. My only gripe, if any, was that only the winning three carried their stories. I wanted to read about them all.
Wonderful...I have memories (and a Bolex 8mm cine film) of a pair flying in incredibly close formation at Farnborough in the 1970s. One of my favourite aeroplanes.
Is this not insulting to people who are unable to speak?
Good challenge, some really excellent images....thanks for hosting. One or two KAP points that are not a whinge/excuse.... Firstly the challenge of framing from a distance without feedback...ok, a lot of people use monitors now; and secondly the technical challenge of creating a panorama from images collected from a bobbing, bouncing platform....that is very difficult.
I was quite excited by this until I saw the image quality. Which is a pity. Could be a good idea if the IQ was a lot better.
Isambard would be proud of that! Interesting to see the trace of an EasyJet dropping into Lulsgate Bottom.... Congratulations.
Great photo...with the shadow of the tail in the condensation pattern....well subsonic though and the condensation occurs due to local airflow expansion, rather than compression....that is why it is at the rear of the wing. The pattern clearly shows the local loading on the aeroplane.
Looks like a Hawk to me.....subsonic trainer....whoops!
Probably the most interesting shot....timing is nice with the head fittings blowing off. How was the shot triggered? I also thought Mach 6 at point of exit a bit optimistic....hypersonic is still supersonic by my way of hearing! All, or nearly all, the aeroplane shots show condensation "shocks" so are very nicely subsonic; funny how a bit of water vapour causes confusion!!.
Great image showing natural aerodynamics at work... Congrats!
abortabort: Rangefinder coupled?
Does it matter at that base aperture and focal length? Street lens that you set up beforehand and point and shoot. Maybe that is where the Art is?
Yes it does look suspicious....can you explain how the photo was taken?
Excellent shot....the sepia does it well.
You need a licence to operate commercially in the UK, but that is for large UAVs. The smaller model ones that carry something like a GoPro are not licensed but the resolution is not wonderful. I use one for kite aerial photography....but it has to be done responsibly otherwise the authorities will react. I suppose in the US it is all about who can/cannot gather data.
He he....on first sight I was appalled...agitated even....but it is all apparent. It is quite ok to have the props on one side and the jets on the other. ;)
The lead-in photo says it all....good enough to fix the photos while you fix your hair. As for battery life? Well my ancient Samsung netbook had 11 hours on it and that was a long time ago....flashy bit of kit though, and sits well on the dressing table.
