Project 8: Altering Colour With Hue/Saturation.

The next process to look at is using the Hue/Saturation control to alter the colours, again i had to have a little search around to locate the control as in project 7 they weren't located in the same place as described in the course material (IMAGE>ADJUSTMENT>HUE/SATURATION). With hue/saturation you seem to have more control over the individual colour compared to levels where the changes you make have more of a effect over the whole range of colours.

What i found when experimenting with these controls was that by moving the hue slider i could completely change a selected colour to one completely different for example with the scene at the station below i had the trees appear as a very nice red colour giving it a very other worldly feel where as the saturation control basically controls how strong the colour appears, if the slider is moved to the left fully then for example the trees and the other green areas become grey while you move it all the way to the right the trees become a very bright green.

With 50% Saturation.

Above are a set of images that highlight how the hue/saturation controls can be used to make small adjustments to a selected colour in a similar way to levels but unlike levels it doesn't effect the colours around it. Here by selecting to alter greens and moving the saturation slider to the right 50% you can see that it makes the green of the trees and plants much stronger than they appeared in the original.

Altered Version.

As with project 7 the final stage of the project is to take this tool and use it to alter one of your own shots. I chose this photo of a hot air balloon because i took the original in the evening when the light had faded quiet a lot meaning that when i came to look at the shot on the computer i was a little disappointed because the yellow of the balloon seemed very dull compared to how it appeared at the time. Now i can fix this problem by using the saturation control in a similar way to the train station image to put the colour back into the photo and have the end result i originally wanted.
