A quick "how to" on HDR

It's "cheating" because you're bending the rules of lighting and going beyond what a normal camera can do.

Like I said, I don't care if people think it's cheating... I think it looks great, but it does have its place.

But the camera doesn't create the images - you do. The camera is just equipment to record them for you to work with :)

I love HDR. It is definitely my goal for this year to learn about it and experiment with it

If a scene has a higher dynamic range than the camera can get in one shot, it's a great tool and gives great images.

I don't really get why people do HDR on a scene that fits fully into the histogram with a single shot though.
Can't the same final image be made by post processing a single photo?

Not if you want to pull out shadow detail. The over and under exposures capture data which the normal exposure cannot. Some folks try to manipulate a single image exposure and re-merge them, but it is not the same.

Nearly all of my so called "HDR" snaps are made from one exposure...

I typically shoot brackets so most of the time I have the stuff to do the true hdr's... :)

If shooting in jpeg maybe but in raw, shadows and highlights can be pulled out very nicely if the original exposure was fully within the histogram.

You can malipulate it, change the exposure, but you can't get more data than the data recorded. If that were the case, it would be pointless to use more than one image.

Some enhanced single images are nice, but it's not the same. LR4 has a shadow slider which is nice for that effect, but you just don't get the same depth as true HDR.

Well I was disappointed, in the content even though it was semi entertaining, because I was hoping the "how to" in the post heading was actually how to. I guess the inverted commas should have been a give away.
