I am using cs2 now but I am new to this PS thing. I like to know what does it mean by hue, staturation, color, luminosity and other blending options. Also, how can I make something becomes glittering like the stars and the sun. Also, how do I colour a plain background?? I find it very difficult since I dont know how to mix and match the colour. I try to make the wall to have a woody feeling or the feeling of the uneven paint but to no avail. Another question what is etheral colours?? I will appreciate your help very much if someone is willing to help me out. Thanks.
