Default Is this shot upto HDR level ?

this is teken from powershot SX40, merged 3 RAW files and little bit tuning. Blurred the background ad hording because they are clear and distracting from main subject.


Distance from sculpture is around 200m

Exposure: 0.5
Aperture: f/5.2
Focal Length: 65.7 mm
ISO Speed: 200

It might technically be HDR if you've merged shots to extend the dynamic range etc. but in this case you didn't go far enough - you still have large areas of clipped black on the far bank and the boat below the statue.

Also be careful of boosting the saturation too much - it destroys detail and ruins a lot of the detail which HDR is supposed to bring out.

Did you actually bracket the shots? You've only described one exposure and usually you'd say how many shots you took (you mention 3) and how far they were spaced (+-2ev for example). Posting the middle exposure for comparison is usually a good idea too. Or even post all three if you'd like someone else to have a go at it.

I think , I have to learn much to achieve HDR.
Well, I used +-2 ev and photomatrix to merge those file.
As shot taken few minutes after sunset.

I think you definitely needed more exposures - notice how even on the brightest one that there are lots of very dark areas - but 3 shots at +-2 is about as much as most cameras will do in a single shot so fair enough.

The processing has lost what little detail you did have though so you might just need to practice with the settings a bit. I had a quick go with your small thumbnails and got the following (mine on the right, yours on the left for comparison). You can see the bright statue has picked up the detail and colour from the darkest exposure and the dark background has picked up the limited detail that was available in the brightest one:

I prefer ianoop's image. A picture taken at twilight is okay with large areas of darkness having just the lights showing through. And there is always a lot of contrast when things are lit by floodlights.

I know what you mean and sort of agree aesthetically but looking at it as an example of HDR, it doesn't work. Maybe HDR just isn't the right treatment for this shot.
