One pic with curve + dodge + burn is not HDR.....
    Isn't it all dependent on the camera? If my camera has super wide DR then why I need 2 pics to capture? The definition of HDR is NOT the number of pics you use. It is basically just how wide the DR of the image is.

    S3pro has roughly 1-2 stops (my opinon) more DR than conventional DSLR's so scenes which require another DSLR to shoot 2 shots at 0 and -2EV, I only need to shoot 0eV then developed the RAW to bring back the highlights.

    Of course if the scene's range is too wide, then must do multiple exposure but 2 stops is quite significant.

    Of course, I said s3pro's single RAW file is not HDR standard YET but technology is so fast-paced and probably in the near future we will see a true HDR camera capable of shoot HDR in one raw file.

    If Canon + Fuji were to work together designing the sensor, it would be a dream come true. Hehe. Clean noise free images + high dynamic range. Makes a nice Christmas treat.

    Yah, I agree with you that HDR is not the number of pics, but the DR 1 shot can hold is limited. Actually HDR=32bit or 16bit. So I dun think s3pro can provide 16bit bah??

    Actually if 2 pics are merged, and if most of the exposure are overlapping, the true capture DR may not be 16bit too....

    Yah, I am waiting for that day when I can shoot HDR with one press of a button. Actually now Nikon D80 has this multi exposure function that can shoot 3 shots with +/- 2/3ev and then merged into one file for the user....however, I think +/-2/3 ev is not good enough, still using exposure bracketing for this purpose.....I think every soon we will be able to shoot HDR in-cam very soon.

    I am waiting!! High DR sensor, I am not sure when, but in-cam HDR processing shound be very very soon.

    Actually I THINK the s3pro provides more than 16 bit. There are times when I develop my s3pro raw files to 16 bit, I find that some of the information get clipped away. I always have to set my CONTRAST to minimum and carefully adjust the exposure slider to fit all the informatino into a 16 bit tiff. This is another reason why I used multiple JPEGs and merge to HDR in CS2.

    The s3pro raw file contains 28 bits per pixel, 14 bits for S pixel and 14 bits for R pixel. compare this to the 12 bits per pixel in a normal DSLR. 28bit vs 12bit is big difference.

    Yah, just did a search and s3pro can provide up to 24bit with SR mode. It is indeed a good cam and it was launched in 04! May be you can try merge to 32bit HDRi loh.

    Hi, may I know what is the traditional method?

    silly question here, but how to get rid of the EXIF info?

    cheers

    I think he meant setting up a tripod and bracketing the exposure. ie shoot 3 or more shots at different exposure settings.

    for my case, I develop using silkypix and they have an option to whether you want the exif or not.
