Photo Editing Guide Part 3 - The Enhance Options
This controls the intensity of the colors. At the minimum -100 value this removes all color and is a simple way of making black and white
images. Most digital images are well saturated, so it’s very unusual to have to turn this control up, i.e. to add to the color saturation. How-
ever, some cheaper digital cameras tend to over-saturate colors. In this example the sky is unrealistically over-saturated, it’s too blue. So
here we use the color-select tool feature to reduce the saturation of the sky blue color only, so the sand and sea are not affected.
You might think it unusual to describe the temperature of a photo, but the light all around you has a temperature (and is generally created by
objects such as the sun or an incandescent light that are very hot things). In fact, you can measure the temperature of hot objects by measur-
ing their color. We tend to associate ‘warm images’ with being more red-orange, and cooler images being more blue - that’s what this control
The Hue control changes the colors in your image. A strength control can adjust this from a very subtle tint towards a certain color, to a
complete re-coloring where all colors are changed to be the desired color.
Combine this with the color-select feature, and you can change the color of only certain colors in your photo, or part of your photo. Instead
of the usual slider the Photo Hue control shows a pop-up with Hue and Strength sliders.
This example uses the Color Select Tool to select the orange, and then the Hue Control to adjust only the color (I guess you can’t call this an
orange any more.) Note that even the subtle reflection on the table has changed color. This whole process takes less than 30 seconds.
Advanced note: Other programs sometimes include a ‘Hue shift’ facility. But typically these shift the hue of all colors in the image, which in
our opinion is not useful in many, if any, cases. Instead, our version of Hue control moves all the colors towards a single defined hue, as the
above examples show.
