Hi,
For physics i am doing research on French beans, and i'm looking if cooking with more salt makes the French bean browner(still green, but more in the brown direction). I cooked the beans and photograhed them all under the same lighting, camera position, etc. And now i have made an image of every bean apart. I want to make a graph of the greenity against the amount of salt in the cooking water, and therefore I need to accurately get the grade of greenity/brownity out of the images. Well, I understand hexadecimal colour values, I want to do it with those, but i first need to make the image one colour. But there is also a bit shadow, and a bit highlight on the images.
Is there a better way with photoshop to check the grade of a colour? If not, how do i make the image one colour?
thanks
