    Unnatural green colour

    Hello,

    Has anyone a solution to the next problem with the Sony Alpha 100: in pictures with great green areas, such as grass meadows, my pictures are mostly too bright and the green colour is unnatural. Other colours are fine. I attached a picture with this problem. I hope anyone can help me.

    It looks like you're shooting without a lens hood and when the intensity of the Sun is near at it's strongest.

    The focus/evaluation of the scene, however, looks not too bad. As for the green, it is not fair to ask us whether the green looks wrong because we weren't there. However, grass in such intense light usually shifts yellower, and green in shade usually shifts bluer.

    As you can see, the light is very bright. You metered for the shadows to look good (see people, donkeys sides). Now everything that is light from the sun will be over exposed (the grass, people's shoulders, the donkey's back).

    It is normal, nothing to do with your A100 but just with the exposure. You can not have both... either properly exposed people/donkeys or properly exposed grass/highlights.

    You can put things a bit "right" with photoshop "shadows and highlights":

    You might want to see this, i found it on a comparison between some SLR cameras

    From:http://www.digitalreview.ca/cams/A100vsD80vsXTi.shtml

    Sony has introduced a feature called "D-Range Optimizer" in the Sony A100. Sony's Dynamic Range Optimizer (DRO) analyzes the captured image data and instantly determines the best exposure and color tonality of an image before JPEG compression. Unlike software optimization of a processed image, DRO is performed in the hardware. In comparison with Nikon's similar D-Lighting feature, there are a few advantages with the Nikon approach.

    yesterday i was attend a sony alpha's class , the lecturer says that use the DRO on Standard in daily use , only use advance in case the lightning is extreamly 2 low , coz the advance option will process the picture with more lightning , so is not suitable for daytime use...... but u cannot use that function on manual mode , so is not a big deal for me...

    Overexposed grass happens. Don't fret over it; it's not always a bad thing.
