Tiger Moth with Pentax K 5 - messing around with hdr - this is weakest in camera setting.

its got like a glow around the plane? like the shot though

^ that's typical of HDR software. If it isn't auras, halos and glows, it's saturation or unsharp masking artifacts.

Contrasty straight lines kill most any HDR algorithm.

The same thing happens in the Canon in-built HDR as well as through DPP.

I'm pretty sure it's because it's a sort of "fake" HDR where it's just choosing bits of the image that are over or under exposed and comping/overlaying an area of an exposure that is correctly exposed.
As opposed to a "real" high dynamic range image which is made by combining data from multiple exposures into an image with a higher bit depth. That resulting image is then usually tonemapped so that the extended exposure data is compressed into a smaller range and is viewable on a monitor at ~8 bits per channel.
Tonemapping is what people are usually referring to when they say they don't like HDRs, after all, who wouldn't want more range

Smoooth resulting image all the same !

Blasphemous image... a Tiger with a tailwheel, and new curved windshields...

Real Tiger's have skids and no brakes.

Real Tiger Pilot speaking, of course. The Tiger I fly regularly is stock standard - no modifications except a radio

Either way, they are a bloody fun aeroplane. I started flying a Tiger when I had 60 hours total time. Passed my 100th hour in a Tiger enroute Maroochydore to Caloundra. Did my tailwheel and aerobatic endorsements in a Tiger (in fact, my old paper license was specially stamped by then-CAA as "DH82 type aircraft"

)

My wife has been many times and LOVES it. Can't get her even to experience a loop yet, but we'll get her there one day.

Several thousand flying hours later, and I still like the Tiger like no other.

As to HDR, well.... there are better ways to acheive a better result (manual tone mapping for starters to avoid the halos - been there, done that). ALL the HDR softwareI have tried is as bad as each other, but perhpas, as H and I have discussed before, Nik's is truly ghastly, unless you tone it down to might as well not have applied it
