Example 1: Cookie Image

MoviesClick the play button to see a video version of this example.

This studio image has no color casts in the shadow, and is the type of image we are trying to create artificially.

In this example, you are not required to change or improve the image, but to use the hue clock to satisfy yourself that there is no change of hue in the shadows. There is a small mystery for you to make guess about.

Start by creating a hue clock, and move it across each of the different colors available in the image, from brightly lit area to shadow.

In the two images to the right, the direction of the hand on the hue clock is pointing very close to the same direction. This indicates that the hue of the white icing, in and out of the shadow is very constant, and we have no mixed lighting situation.

That the hue clock is tremensously sensitive to color. In this case, it indicates an orange color, and this color is not very obvious to the eye. When in doubt (and that should be most of the time, when it comes to color!) trust the hue clock over your own eyes.

Let’s look at some of the other colors in this image.

Dragging the hue clock’s sample point from one end of the yellow icing to the other shows that it is the same hue for both the shadow and lighted areas – again, this shows that there is no mixed lighting situation causing a difference in color between light and dark areas.

Ditto for the gingerbread-colored cookies themselves – the hue clock is very close for shadow and brightly lit area.

The blue cloth background is also an object in the image, though perhaps not as important as the cookies themselves. Here we do see a bit of a color shift, and this points, perhaps, to a small mystery that I’ll discuss shortly.

The yellow background is also very close in hue. By now, you should be familiar with dragging the hue clock around, and satisfying yourself that an object either does or does not have different color in the shadows and the more brightly lit areas.

If you like mysteries, here’s one for you. I should warn you that I don’t know the answer for sure, but I do find it interesting. Where the plate lies on top of the blue cloth, the hue clock points toward yellow. Outside of the plate, it points between blue and cyan. Where, oh where, could this yellow color come from? It could be several things. My favorite is that it’s a reflection of a yellow ceiling or other yellow material in the room.

That’s it for the cookie example. Take care, and happy curving!
