HDR setting or exposure bracketing

I've not had another go with mine yet but feel sure it would be much the same. It's the same image file after all.
Re not looking like HDR, that can often be a good thing - just a subtle improvement in the dynamic range without going over the top. The PS one has the best contrast with the hedge on the left looking much more detailed. And your Photomatix one has brought the sun out too!

If the the photo directly out of the camera doesn't look like the way you remember it when you took it, it seems HDR can help you achieve the look you were expecting. Some HDR is truly over the top but even then if that's what you want, who's to say it's wrong?

What I really need to do is take multiple exposures for an HDR and compare them to the result of processing just a single RAW file, along with an in camera version too. It could be the K-5 just doesn't get s much benefit from HDR as most other cameras with an inherent lower dynamic range.

Its a pity it couldn't bring the sun out in real life LOL It was a very cloudy overcast day.

would be interesting to see the difference with the in camera and the software using more files.

The sun is out here today!!

Well you can't compare what you haven't got so a challenge to find some suitable scenes and make some comparisons?

This is HDR with seven exposures:

Works very well for that John

The scene in John's image is exactly right for HDR processing. It has extremes of light and dark areas and HDR is used to bring those extremes closer together. Great image.

John, Is that 7 shots combined in the camera or 7 individual shots combined in software?

7 shots at different exposures (-3, -2, -1, 0, +1, +2, +3) combined in Photomatix.

That is certainly the way to do it John, a superb example of how effective a good HDR can be.

I have been using a package called Zoner which is a sort of PSE clone from Eastern Europe. It seems to have a very good exposure merging and tonemapping facility which offers quite a lot of control and I have been pleased with the look of the resulting images. My previous attempts at HDR church interiors has been using the inbuilt HDR facility in the K5 which were not in my eyes quite as successful.

Last week I took some bracketed exposures in a German Cathedral ( 3x 2ev) , but I realise that I should have gone beyond three exposures - certainly 5 and maybe 7 as John Riley suggests. I have had no problem aligning 3 handheld images but wonder whether 7 would require a tripod.
You don't need multiple exposures to get HDR shots with a K-5. Completely unnecessary and a waste of time. The K-5 has plenty enough dynamic range. You can 5 stop under expose and still recover.

just take one image and expose to avoid clipping.

I will try a drastic underexposure and see what results. Thanks for suggestion - it could save a lot of time, if it works for me!

Drastic underexposure will just give you noise in the shadows if you try and bring out any detail. The purpose of the +1, +2 and +3 exposures is to record shadow detail properly and avoid that noise.

It also makes sense that the dynamic Range of the K-5 is that good you can bring up the shadows an awful lot without noise being a problem.

And in any case, no one is suggesting drastically underexposing, the idea is to expose so you don't clip highlights.

And even if you're intended shot means that even the K-5 can't cope with the boost in shadows there's no need to take squillions of exposures 1 stop apart. Just take 2 shots, one to cater for the very darks.

Anyway drastic underexposure will NOT give you noise in the shadows that's of any problem....

See here for proof

but don't take his word for it. You have a K-5 so try it. Amazing
