    Default A question regarding ex[posure

    This image of a Snowy Egret was taken at the Viera Wetlands a couple of days ago very late in the afternoon. I checked the histogram and it appeared to be just right. There were no blinkies, but I seem to have lost all the feather detail on the top of the head and the upper back of the bird. In fact these areas look blown out. Cananyone tell me how I might be able to correct this kind of error? All ideas are welcome and all general opinions regarding the image are welcome as well. Shooting data is as follows:
    Nikon D4
    2013:02:19 18:18:13
    850mm
    850mm (in 35mm film)
    1/500 sec, f/6.3
    Mode: Manual
    Metering: Multi-segment
    ISO: 800
    AF mode: MANUAL
    White balance: SUNNY+2
    Flash: Off
    File size: 19.0MB
    Image size: 120 x 160
    Saturation: Normal
    Sharpness: Normal

    Wheeler:

    Sorry for the slow response.

    The D4 is usually pretty tolerant of overexposure of the whites compared with earlier bodies, so it is surprising that you didn't see any blinkies, but still lost the whites

    I know what has happened to me in the past is that when chimping images, I got off the screen that shows the blinkies, went back to shooting, and wasn't getting any blinkies, and didn't realize I was on a different screen until later, having overexposed some images in the meantime.

    It is also possible to have a problem in the conversion process from the raw. Did the original raw file show the lost of detail and a histogram off the right end?

    In regards to the image in general, because the reflection is not too strong, I would crop up from the bottom to try and remove some of the debris in the water from the frame. I like the reeds in the distant background, but would consider removing the one by his back and face.

    Always a challenge to get a clean shot at these fellows!

    Cheers
