Assistance in shooting plain HDR

Hello!

English is not my native language and am experiencing all the technicalities surrounding CDHK as difficult, but I will do my best to make myself understood in this issue.
All I want is a function, with which the camera automatically shoot three pictures with different exposure values (lowest, middle and highest).
I have searched for help on the forum and put down a great deal of effort, but without succeeding. Installing CHDK on my camera (Canon G9) was no performed without any problems. However, I have tried almost all HDR-scripts, without succeeding. At one point, the camera did take several photos by itself, but it did not use different EV-values.

Can anybody tell me what type of script of method that the would recommend for me. I will be happy to try it out and I will report on the problems that I encounter. Hopefully, in the end I will succeed with this.

Thanks in advance

In English, this is called bracketing. Maybe http://chdk.wikia.com/wiki/CHDK_User_Manual#Bracketing_in_continuous_mode will help.
Don't forget what the H stands for.

Thanks for you replies.

I believe myself to be closer the solution now.
These three images was shot automatically using the bracket-timer-method:




However, the problem now is that my HDR-software does not recognize what EV-values the pictures has. When I open the three pictures above in Dynamic Photo HDR v4.65, the software can't find the EV-values in the images exif-data.
It looks like this:

I can always type in the values by hand in Dynamic Photo HDR. I set the TV-Bracket-value at 2 Ev, so I am guessing that the I should type +2 for the lightest image, 0 for the middle and -2 for the darkes image. This is the result that I achieve then:

What do you guys think? Should I use other EV-values and how do I make the camera save the EV-values in the images (as it ordinary does when shooting HDR)
