Geez, and there I was thinking that's what Superia looks like 
Well, at the very least you seem to have dispelled the myth that film has a higher dynamic range than digital.
EDIT - so how did you manage to create an HDR image from scanned images? Did you use either of the techniques described in post #2?

It does. The shop gives me an unadjusted file. It's like raw in digicam terms.

Print film has a wider latitude. So what? Digital has a screen on the back of the cam. It's slide film that's tricky. It's easy to get the exposure right with digital and print film.
The shop's scanner has a big latitude. That's all.

and that unadjusted file is a jpeg? Are they/you using Silverfast?

Yes.
No. It's a Noritsu minilab. It uses it's own software.
You're looking at the light source:
Program mode +2 exposure comp.
But, who takes a photo like that anyway?
All these look the same, regardless of the acquisition format:

Well, that's the thing with Photoshop. You can make anything look whichever way you like. Sit doesn't matter what you shoot with, right?
Question is, where do you like to spend more time: behind the computer or behind the camera?

No. It can't. If the exposure was wrong, it's stuffed.
The camera.

You're going to hate me for this, but if you were shooting raw, you wouldn't necessarily be...
Maybe I'm still half asleep but you lost me on the point your making.

Thought I'd report back after all the suggestions etc. on Friday...
I used Photoshop's NEF import dialogue to import the following RAW (NEF) image 3 times, one at the original exposure, one at -1 and one at +2 (just looked better this way - range seemed wider than -1 to +1):

Used Photomatix to create a HDR image from the three versions of the image, tone mapped with the following result (also cropped slightly):

The images I have uploaded are fairly small and one way or another they are not as saturated as they look on my 32" monitor or my MBP monitor (think I need to look at the calibration settings) but I had a good time with this and I think they serve to illustrate that a fairly good HDR image can be generated in this fashion. Maybe not as 'out there' as some of the HDR stuff I have seen but I feel the tone mapped one is a very nice enhancement.

Nice - although heavy saturated in Safari it's much more sedate in Firefox
IMO often the harder it is to tell its HDR the better it is.

...Any idea why that is? Just had my knickers in a twist over it.
Incase ppl are wondering whats the difference:
@SlinkyMike - if you'd prefer I not use your photo as an example please let me know and I'll remove it immediately.
BTW - if you're looking for a calibration I can vouch for the Spyder2Express.

Safari is presenting the photo the way its supposed to be as it respects ICC profiles. You can tell the most recent version of FF to the same by going about:config and changing gfx.color_management.enabled to true.Thanks

No worries abut the picture - I'll consult the subjects though and get back to you if they have issues.
Great tip about the Firefox switch (gfx.color_management.enabled = true) wish I'd known that a few minutes ago, would have saved me a few 'face-palms'
The more saturated version (a-la Safari/FF once colour is management enabled) is as I finally left it at about 12am last night, eyes were a little tired and dry by that stage, what do people think? Over saturated?
I think maybe a bit...

I believe that FireFox 3.1 will have colour profile support enabled by default.

I dont like the way photoshop handles HDR though. Have you tried one of the dedicated apps?
I gave it a shot...
Tried with 3 and 5 shots, now this is using a point and shoot, while sitting on the ground and using my knee as a tripod. Result: Moderate success. It was slightly blurry cause of the camera moving around slightly but it wasnt too bad. What I need to improve on though is figuring out what each of those sliders and other adjustments in Phtomatix Pro 3 do. It will take some time, but I will figure it out. Is photomatix the easiest and best program to use for HDR?
