Hi
may i ask a question which is the first step/steps when you are going to edit a photo?
the thirst thing is watch the lights in camera raw , and the white balance
after straighten , and find the black,white, gray point and use a level
so
1) tweak lights
2) white balance
3) straighten using natural vertical or horizontal lines
4) the level with black white and gray point
about the fourth point , i would like ask an opinion
reading a Scott Kelby's old book he suggests to find a black point with photoshop threshold adjustament layer and a white point moving the slide
after create a 50%gray layer blend mode difference and find the gray point and use level eyesdropper (black / gray/white)
now ,is still necessary or useful the fourth step?
thanks
cheers

I have CS5, but I don't know how, or even understand how to use it
