If you have a remote there is no real need to use the 2 seconds delay, only if you use some long lenses and a not so sturdy tripod you might notice a difference. For the lenses you have I wouldn't use it.

If you use a wired remote and the camera is on a tripod, don't forget to switch of the SR redutcion, it can blur your photos.
With wireless it's automaticly switch it of but not with wired so far as I know. If you use a delay the SR is also switch off just that you know that.

there are also electronic wired remotes, you can program some of those so that they take all the shots with one press on the button.

I do it so as Jackie, and since I use CS4 it opens the original DNG file with the changes aplied with Lightroom. So if I save I save it over the original file so i saved it as tiff if needed or straight to jpg if I wouldn't do any proccessing later or if the processing was simple.

btw I love the crop tool in lightroom with the third rule lines in it, is there anyway to get them in photoshop as well?

Here are some photos and they look similare so you can compare them easier.
Pentax http://www.photozone.de/pentax/134-pentax-smc-da-16-45mm-f4-ed-al-review--test-r...
Sigma http://www.photozone.de/pentax/147-sigma-af-17-70mm-f28-45-dc-pentax-k-review--t...

Oh wait you have a k10D sorry
Yes it only fires one shot, only the K20D can do it.

Look for a remote, they arent that expensive and handy for these kind of shot.
If you look for a wired one simply get a third party device that works on the canon 400D, they have the same connection. I got my for €10 in the shop I believe. I also have the wireless Pentax remote F, that one is so small that it will fit in your battery grip.

Gently is the key here, quite differend then what other HDR photos looks like. This a good example how to use it in my eyes.

Does Potomatix do it better then Photoshop if so I need to try it

Yes and they work in 64 bit version, there is also a special version of neat image but don't know if i will get it.

One thing that annoys me is how long it can take with topaz denoise to filter out the noise, it can take some minutes if you set it on the highest quality. Neat image did it almost in seconds.

It has to do with the bit size, you probable are in 16bit and jpg doesn't support that. you can set down the bit rate in Image > Mode > 8 Bits/Channel. if it's already on 8bit then something else is the problem but this the most likely one so give it a go.

I've seen him before too, really wonderfull shots there.

non of my failed so far, never had any hick ups either.
I've a sandisk 8gb extreme 3 and a sandisk 2gb extreme.
The 8 gb is basicly living in my camera and the 2 gb is there for backup.

You really see that the glass downgrades your image, or else they would have been so much better.

Wonderfull photoshoping tel, it surely looks a lot better
