  • vrimg vs. exr vs. jpg can someone explain a newbie how to get the same lighting?

    Hi,

    I am not an expert, but found that I can avoid crashing while rendering my model if I save the rendering directly as a vrimg.
    I managed also to convert this to exr and open this in Photoshop.

    Now my question, in Photoshop the image looks kind of "overexposed".
    If I render "normal" and not to the vrimg the result has the colors and exposure I want in my end result.
    Is there a way to get the same result from the vrimg file without tweaking a lot in photoshop?

    The only reason for me to use the vrimg is that I can easily render higher resolutions without crashing.

    Thanks for keeping the answers practical and easy understandable.

    Thanks for your help,

    Franzi

    In Ps go to Image > Adjustment > Exposure.
    Play with the gamma correction. If i remember correct 0.4545 is the correction i used.

      The reason for that is because its an image with a high dynamic range and you have to tweak it to make it look normal. You have to make it an 8bit image and adjust the color curve to be able to convert to something usable. I would NEVER save an image as JPG from Vray as it really reduces the quality of the image. PNG is the best for good quality unless you go EXR or HDR.

        If you switch to 8 bit mode an exposure adjustment window will pop anyway. So you don't have to switch to 8 bit, you can stay on 32 bit after exposing correction, and still use the high dynamics advantages of the image.
