Thanksgiving with Images

To edit all of my images, I used Adobe Photoshop. For the first image, I brought down the brightness and turned up the contrast. Then I made the hue a little, but not noticeably, greener. I also dialed up the saturation and dialed back the lightness of the image. For the second picture, I brought the brightness down only slightly and turned up the contrast. I left the hue alone, because if I had changed it too much, the pumpkin would have been blue or green or purple. I also played with the saturation, bringing it up a little. I darkened the image. For the third image, I turned the brightness down and increased the contrast a lot. I made the hue slightly greener and saturated the image a lot. Then I darkened the image a bit. For the fourth image, I brought down the brightness and increased the contrast considerably. I didn't touch the hue but turned up the saturation a little bit. I then darkened the image using the lightness controls.
