On WOH_9540 in the Supersonic challenge (2 comments in total)

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.

On HIMARS6-X3 in the Supersonic challenge (2 comments in total)

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!!.

In reply to:

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?

On Judge strikes down fine against drone photographer news story (127 comments in total)

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. ;)

On Integrating the MacBook Air into a pro workflow article (352 comments in total)

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.

On FED 3 in the A Photograph of your old Camera challenge (2 comments in total)

Excellent camera...I still have one complete with a range of Jupiters and a Steam-punk turret assembly for viewing through. Learn about photography through having an unlimited access to TriX (this was in 1965) and the reloadable cassette. Mine is now loaded with Ilford FP4... Oh.....memories! Nice processing...

On Panasonic Lumix DMC-GX7 Review preview (548 comments in total)
In reply to:

babalu: Hey, can this be true ??
The one point which probably has led to this camera not getting the highest award, is : No In Camera RAW conversion.
Well, that feature IS available with the GX7. See user manual page 140 .
Quality modes available include RAW+JPEG, whereby JPG can even be set to high or low quality .
Am I blind or completely off the topic, or what ?

I have been away for 10 days with the GF7 (Guatemala) and found it perfectly satisfactory to WiFi, or SD card JPEG input to my Nexus7 Android and use that software to do any JPEG fixes before winging the stuff onto the Internet. The RAW (always take RAW+JPEG as with the M9) is going to be done in the comfort of my home and with a proper computer/software. Don't see the need, or use, of in-camera RAW conversion at my level of photography.

jezsik: As much as I appreciate the other images in this challenge, I think this one does the best job of illustrating the article. Sorry it did not rank higher!

thanks.....but actually I should have been DQ'd for not reading the rules...but then no-one would have recognised me.
