If the expcomp file it doesn't show up with (at the start of the line) "-rwx" then you'll need to reset the permissions:Code:ls -l expcomp
I'd also advise reading something like http://freeengineer.org/learnUNIXin10minutes.html to get to know a bit more about what these commands are doing.Code:chmod 755 expcomp
Really appreciate it

I finally wrote a script that takes 5 pictures from -4 to +4 with 2 exposure intervals
It takes around 20 secs to take the pictures and they will be in your MyDocs folder
photo_bracketing.sh

If you're still around, your script doesn't seem to focus properly. It seems to use the exposure settings from the last photo taken with the camera app, but not the focus settings.
I made myself a tripod mount using an old hair clip and a piece from a broken webcam, and took a picture of a very backlit miniature. The miniature was sharply in focus. I then used the script to take three photos, but the miniature was blurry in all three!

Yeah that's why he said you need to compose a picture using the camera app before running it.
Someone should write an autofocus script and autoexposure to be used before running the HDR script

bachagabriel: I did compose the picture with the camera app, and the photo I took in the camera app is in sharp focus. But the photos taken by the script after closing the camera app are all out of focus.

Indeed seems very cool. Can't wait to get this in a format where I'm not too scared I'll break my device with it :P
There's a couple of these rogue projects where no one is actually committing to make an app for it, just want to see what's possible. Other one is for example this one: http://talk.maemo.org/showthread.php?p=555611

You would need to set the camera to 'action' or 'landscape' to disable autofocus first. That does work for taking pictures with manual focus, I haven't tested it with the HDR scripts myself.
edit: I did test it now, it doesn't work, as soon as the camera application is no longer active, the focus seems to be reset (you hear the clicking sound).

Here's my HDR photo. Colours in the final combined picture are good, focus is bad:
The light outside the windows is bright, and in a normal picture the miniature is almost silhouetted or the windows are overexposed.
