Using the image from the previous screen, we can open this JPEG format picture using Photoshop and we get the following display.
There are a few different ways we can adjust colours in this format image using Photoshop, but my favourite is the 'Variations' command.
To select this choose 'Image', then 'Adjustments' and then 'Variations' as shown below.
You'll then see the following display. Make sure that you have the original image selected to start with by clicking on 'Original'
in the top left hand corner. Then to reduce the amount of warm colours in the image click on their opposite cool colour. So, blue is opposite
of yellow, green is opposite of magenta and red is opposite of cyan. To reduce the amount of yellow, click on 'More blue'. to increase the
amount of yellow click on 'More yellow'. If you make a mistake or are not happy with what you have done, simply click 'Original' and
start again. When you think you are happy, click 'OK' to accept the changes.
In this case, I just clicked 'More Green' and 'More Blue' once each to get the following. Then I clicked OK.
Now when you see the image larger, after applying your variations, you may feel you've overdone it a little. Here is where the 'Fade' command, one of the best
Photoshop commands, comes in really handy. It allows you to fade the last changes applied to your image. It only affects the last command
so if you do some other editing you won't be able to fade the variations. You use fade by selecting, 'Edit' and then 'Fade variations' as
shown below:
This causes a small pop-up window with a slider control to appear. Slide the control to the left to fade your variations by the required
amount. What a great little feature.
And here's the final image as it appears on my site...
