    Changing light on canola

    These were taken from roughly the same position on successive nights. The processing is a bit different as they were done at separate times. However I was intrigued by difference the light made to the colour of the stubble.

    This was done at sunset, the stubble in the shadows is green and in sunlight is yellow brown

    Changing light on canola

    This was taken the next night just before the sunset. The stubble shows a bit of green in places, the majority is yellow brown. I was surprised the green was so obvious in the shade and that sunlight would make such a difference. I wonder if it may be like shaded snow reflecting the sky, and thus blue. But the green defeats my limited ability to explain.

    I'll leave the science to others. I like the colour pallette in the first shot, Trevor.

    I amended the initial post, but I am still perplexed about the green.
    I admit I prefer the first image for the same reason you do.

    Really interesting, Trevor!

    Consider cropping the first one at the top ever so slightly above the pink cloud that has a vertical shape. The light blue tones of the sky above that area add an element that detracts for me from the otherwise simpler palette.

    Thanks Mike Good point, even with a rough crop by sliding the image up on the computer I can see your suggestion makes a stronger image. I am not attached to rigorous adherence to traditional format sizes so a wide narrow crop is quite acceptable. I have yet to go completely free form with the crop and have amorphous shapes, but one never knows!

    I like how the sky remained pink on both and the warmth of the fields compliment the atmospheric changes.

    Re: Changing light on canola

    If you had waited until after sunset on the second day, I wonder if it would have still shown green Trevor?

    IOW, I am wondering if the stubble has dried out and turned more yellow-brown between the two images due to the elapsed time and drying out/ageing action of another day's sunshine.

    Intriguing, Dave

    I have no explanation, however I really like the images, particularly the first.
    Well done.

    Re: Changing light on canola

    The change in color of immature canola seeds (green in color) to mature seeds (yellow in color) seems to involve a decrease in the chlorophyll content of the seeds. What might have occurred between the two days the photos were taken was a decrease in chlorophyll content of the seeds as they progressed from an immature state to a mature state. If that was the case, then the lighting is not responsible for the color differences seen in the two photos. The chlorophyll content of the seeds changed. I base this suggestion on information and photos which can be found on page 5 here:

    I prefer #1, such a nice image Trevor. And I agree with Mike about the crop

    Nice shots, Trevor. The only canola I've ever seen is a lovely golden color, rather translucent.

    Both are very nice images. For me, it's a hard call which is better, although I do agree with Mike about the crop.
