i've read some guides on HDR and most of them mentioned bracketing..
confused, must use bracketing? or can i use the same raw file to create 2 files with different exposure and then do HDR? :dunno:
There were some discussion on this single raw file HDR before.....if you search, you can find.
But if you read the definition of HDR, it should be at least 16bit/colour channel to capture the real dynamic range of a scene. Therefore, if your sensor is only 10 or 12 bit/channel, then the amount of data collected in the RAW file is never enough to qualify as a HDR. So, with a single RAW, I personally think you can get the same effect by adjusting the Highlight/Shadow of the RAW file....dun need to do a fake "HDR".

Hmmm ... which DSLR has 16bit/colour channel? FujiFilm S5 Pro? What else?
Yeap you can.
If you shoot in raw, just open the raw editor and export the picture as JPEG 3 times:
a. underexposed by 1 stop, decrease the brightness/exposure value by 1
b. correctly exposed.
c. overexposed by 1 stop, increase the brightness/exposure value by 1
When you launch the HDR programme it will tell you that it cannot detect diff expo levels and will ask you to manually key in the exposure levels for each photo
Put -1, 0 and + respectively. After generating, click tone mapping and adjust accordingly.
It should work.
There are instances whereby you can only shoot one picture and if you want to HDR it, then RAW is your only option.
Example, during my friend's commissiong parade, i took this RAW image and HDR'ed it. JPEG would not have been as effective due to the ghosting effect it will cause if i take 3 JPEGs and the men are moving around.
For normal landscapes, taking bracketing would be better as it is more accurate.
An impt thing to note when taking HDR is the noise levels it tends to create when the highlights are strong. To reduce this effect use a GND filter or noise reduction software.
Hope this clarifies.
Hi g-khoo, did you try to use shadow/highlight and masking with layer if necessary to get the same "HDR" you get with one RAW?
When you convert your RAW, just "exposose" it to the mid range for a start.
Nope i didnt. I just manually adjusted the exposure levels when editing the RAW files and then export them as JPEG.
After that i just use photomatrix.

Bonk.
Did you know that you can just open your RAW file in Photomatix, and it'd do all that and more for you? =D

I suppose you could also do it in photoshop, duplicate the layer -> stack -> overlay -> adjust shadow/highlight -> mask/unmask.
But photoshop more troublesome la... Although it gives u more control.
Nice HDR u got there bigboy_cad
Hey night86mare, do you know where I can buy photomatix (not online, dun like to do online transaction) from store in CD/DVD form? Thanks.

Bonk.

i've tried experimenting with photomatix and creating 3to5 different exposure files from One raw..
but the results is no where near g-khoo's nor bigboy's piece of work :sweat:
is there more to it than just photomatix? it's really simple to use. but results look so different heheh.
i've tried 3 exposures and 6 exposures at about 1stop apart.Are your exposures far apart enough in terms of dynamic range?
