    HDR attempt

    i tried to make this HDR from just one image. I changed the exposure on two of the images then merged them. This is what I came out with.


    Sony A77
    Sony A580
    Sony A 100
    Maxxum 400si.
    Sony 18-70 Kit Lens
    Minolta AF 35-70
    Minolta AF 50 f/1.7
    Tamron 70-300 f/4-5.6 Di LD
    Tamron 60mm Macro
    Tamron 17-50 f/2.8
    Tamron 2x Converter
    Sony HVL-F42AM
    Quantaray 70-300 4.5-5.6 Macro

    What's the original look like? I think you've posted a railroad shot like this before. Usually HDR shows the actual image with just more bright highlights and colors and can take more than 2 shots to merge.

    I did post the original before but here it is so you don't have to look for it. The question I asked was never answered can you make a HDR from just one image?
    Thanks Frank

    The original looks much better. For the record, technically you cannot create a high dynamic range image from one capture. There is nothing stopping you from trying, but it isn't HDR.

    You need at least 3 images (-2, 0, +2) and for best results sometimes 5 or 7.

    Okay, yes, it can be done ... it's not quite a dramatic ... but, yes.

    It's more like playing with exposure than anything else ... and important detail is most certainly lost or imperceivable

    Personally ... posterized is my preferred technique.

    Then, you could vignette and throw a frame around it ... just for grins Similar to your initial effort.

    There are so many ways to skin this cat ... HDR? Not so much.

    HDR is a completely different process altogether, and has nothing to do with Photoshop filters or creating artificial looking effects.

    Agreed ... but I was looking for impact, to hell with exposure adjustment. I see nothing to be gained with it, in this particular image, so I abandoned the pursuit for expediency and artistic challenge.

    As the Canonites might add: YMMV

    My own limited vision, I suppose.

    Frank probably knows what he's after.

    Actually in RAW mode (YMMV since I don't know if it's with all cameras), I've seen some HDR images done with multiple images and 1 just by adjusting the exposure and the results were nearly the same. So I guess it is doable.

    Just bump the exposures both ways in the RAW format and try merging them together.
