    Thanks William,

    But is the one I submitted qualify as HDR?

    Just the smoke seems too "clear" to be a normal picture.

    Yep , I'd say by the look of it , It's a single RAW image HDR , Mr Felix , Go to photomatix web site you can download a free trial version , Just has water marks on the images , Or buy for $90 , You just have to load one RAW image in , Use the default settings for processing and you'll get what they call a pseudo HDR from a Single file , Which works if there is a heap of movement , Thats the easiest way

    "HDR stands for Hard to Do Right "

    don't you mean Hard to Do Tastefully?

    I actually blend my HDR images by hand, now that I have a graphics tablet (wacom intuos4) I can do it significantly faster and with far more control than what was previously possible.

    OK, next question.

    My 330D made .CRW files.

    Now with the 550D and I take RAW images, I get .CR2 files.

    Adobe says it can't load them.

    Short of re-naming them - a typical windozxe fixall - what do I need to do to get Adobe to load the files?

    You'l probably need to update to CS5 for it to read .CR2 files from a 550D , Each new version of PS includes updates of new Cameras , Dont think the 550D was out when CS3 was released

    Ok, next question.

    For the sake of learning, while at Parramatta this morning, though I don't do raw files because of the problem mentioned above, I bracketed a shot of some balloons. PhotoShop didn't mind loading the three pictures with the HDR thingy/function.

    Ok, it did some things itself but then what happens?

    I tryied to save the picture but couldn't save as JPG.

    Saved it as the PhotoShop format and tried to look at it.

    It is HUGE! And it won't load. 23MEG I think.

    I am trying to get my head around the process, but if someone wouldn't mind giving me a bit of help.

    HDR are 32 bit images. JPG are 8 Bit. If you want to save the resultant photo, go to Image > Mode > and change it to 8 bits/channel and then you can save it as JPG
