I was outside in the garden, staring at all the frost-covered items: grass, plants etc. But I then found a green leaf in the soil. I quickly got it onto the grass and took the photo.
Now, it didn’t look like this when I took it. In order to make it better, I put it into Lightroom CC and changed the Exposure, Contrast, Whites, Blacks, Vibrance, Saturation and many other settings. I also applied these exact settings (I may have changed a few of the numbers to suit the individual image) to a few others.
