I often tweak exposures on the original frames before sending it to Photomatix, so by all means carry on doing what doing! :) Well the beauty of RAW files is as you say being able to edit exposure, white balance and tones.

I have been opening my raw files and sync them before creating an HDR photo in Photomatix. I sync clarity and vibrance; lens correction; auto white balance and exposure. Or should I not do that?

I think that from this point of view it really sounds like a big difference (256 to 16384). I am sure you know it I only want to enforce your explanation. Great tutorial thank you, Kind Regards, Karol Chris,

The first is that you cannot create a HDR from a single JPEG it's impossible. If you are shooting a scene where there is lots of movement say... people walking around in the frame, or tree's blowing in the wind, when you compile the HDR it's going to ghost and theres nothing you can do about it. The reason it's impossible to create a HDR from a single JPEG is because there is only 8bits of information stored in the image file when it is rendered camera side. RAW format on the other hand has 12-14 bits of information stored in the file, it doesn't sound like a big difference but it's these extra pieces of information that allow us to create HDR form single RAW files. The second disadvantage of shooting in JPEG is that you have no flexibility when it comes to processing the shots, any mistakes will be committed the second you press the shutter. Shooting in RAW allows you to correct any mistakes such as white balance, color saturation, contrast, and sharpness after you have taken the shot. How do you know that they were taken in JPEG? Even raw files end up as JPEGS or TIFFs once they get compressed after the initial processing. I shot in JPEG for a long time and as you say most of the time the end results can't be told apart (because they all end up as JPEGs at the end of line anyway) However because shooting in RAW has it's advantages, if you can shoot in RAW you should.

And, considering that there's a few folks walking around in it, its darn good. Luckily, there was no distiguishable blur. Great stuff!...
