Hello, this has probably been answered somewhere, but while i'm looking for it, i thouht i'd post this to ask anyways in the hopes of someone responding shortly.

If i do exposure bracketing on my camera (say -2,0,+2)
and i take those three raw files layer them over one another in photoshop and do custom tonemapping by playing with layers, is that legal in advance editing?

thank you

Nope, sorry. From the rules:

You must ... create your entry from a single capture.

nope, not legal...it has to be from one image...What you can do is make variations of the same exposure image in PS so it looks like different exposures, and then combine them in Photomatix, or other HDR programs. (right?)

You can only use more than one camera capture in "Expert Editing"

I believe that the Advanced Editing rules state that only one source image may be used.

Having said that, I tried using one RAW image and exposed it multiple times (three) so I could merge those in HDR. PS CS2 has a problem with them because it reads the EXIF info and all three have the same info. There are ways to strip the EXIF data to get it to work, but I haven't tried it.

Thanks everyone

So basicly the only thing i can do is take my better exposed Raw image, change the exposures in raw converter and then use those? so long as all three are infact the same picture just with different exposure levels from the raw converter?

Thanks

That's correct; I call it "quasi HDRI" as opposed to "true HDRI". It works pretty well as long as the tonal range you are trying to cover isn't too extreme.

I don't think you have; they are not legal. However, some shots with ultra-wide-angle lenses look like panoramas if they are cropped skinny.
