    From a single file processed in triplicate. Happy with the way it turned out given the single image processing. I usually like to use at least three.

    Cheers!

    Nice, Linc. Good catch.

    Linc this is so dreamy! I love it!

    A heavenly mall.

    Tell me what you mean by singl file processed in triplicate. I've processed single RAW files and tonemapped them but what do you do here?

    I love this look. It looks like it was done for an advertisement. Very nice!

    My desire in photography is to capture the essence of life, to make others catch their breath at the purity of the moment captured, I'm still working on that.

    Jen,

    What I do is convert the Raw File three times at equal intervals.

    I use Apple Aperture, but Camera Raw will work the same.

    Take the original RAW exposure and export it to a 16-bit tiff. Don't change the exposure value. This is going to be your +0EV exposure. Then, take the exact same RAW file and move the exposure slider to -2EV (or -1EV) to reveal highlight detail and export again to 16 bit TIFF. Then do the same thing for the shadows. Move the slider to +2EV (or whatever works. You just want the spacing to be consistent) and export to 16 bit tiff.

    Now you have 3 tiff files at -2EV, +0EV, and +2EV. Go to PM. HDR>Generate. Browse for the files and click OK. With this method you can uncheck the align option. It will ask you to check the exposure values. Change the spacing at the top and then the value for each shot in the main frame. It will combine them and you can tonemap like usual.

    I have experimented with this doing 3, 4, and 5 exposures. Some images seem to work really well, others don't turn out so well with this method.

    One thing I've found is that my camera will recover about 1.5-2 stops of highlight detail from raw files. So I could have a RAW file with a blown out sky at +0EV, but when I move that slider down to -2EV, I can usually get most if not all of the lost detail back.

    However, if I have clipped shadows, there is no hope! When I move the slider up, an insane amount of noise is produced. I can get about +1EV from shadows and still have noise that is manageable with DFine.

    For this reason, if I think I may use the file for HDR, I always use exposure compensation to give me a brighter original file when I shoot it. So I might expose the original at +.5EV or +1EV, to make sure I get sufficient shadow detail, and then when I process the file multiple times, I may be able to push the exposure on up one stop and then down three.

    I read an invaluable article about digital capture and proper exposure that explained why those RAW files contain so much highlight detail and how to properly expose to take advantage of it.

    I hope this helps. It's long and probably unclear given my communication aptitudes, but I'll be happy to answer more questions.

    I usually get better results with this method than processing a single RAW file in PM. PM seems to throw away a lot of the highlights from the RAW that I could otherwise recover.

    As Jen said - dreamy - I really like the way this has come out - I do the same with single images in Lightroom - as Linc says sometime it works and sometimes not

    Thanks Linc. I will have to bookmark this and read it in detail when I want to try my best to get the detail out of 1 RAW image as you explained.

    Thanks for the good explination!!!

    Great image nicely done.

    Perhaps it would help everyone if you'd post an original image right before tonemapping, maybe tonemapped with the default settings, and then a screen shoot of your image in Potomatix that would show the exact settings for this, eg. sliders and values.

    Cheers.
