I'll use cartoon or cartoon-like images in my site. In my some articles I'll have more than 1 images that is related to the content. After finding the suitable images I want these images to match by means of colors and density of light they use.
So, for example there are 2 images below:
My favorite one is the upper one (Rosa Parks). Pastel, soft.
The lower one (I name it justice) is as you see is dark and not-soft.
My aim is to resemble the "justice" image to "Rosa Parks" image as much as possible by means of color tones and light density.
Q1) How can I achieve this with photoshop? (I have version 6)
Q2) I couldn't find a satisfying tutorial on web so since I don't know the technical terms of photoshop world I used wrong search keys. If this question needs a very huge answer, can you provide me correct searching keywords and/or some links you know
thanks in advance regards
