Here's a minor example of what's possible working in LAB. This tends to be my prefered color space since it allows for the adjustment of lightness without affecting the saturation of color. The curve set i use for nearly all images tends to be the same! go figure. Slight variations for cast removal and/or saturation tuning. Its remarkable what can be achieved in just a few steps using LAB. Corrections that could take a professional hours or even days, take a matter of minutes with LAB. Whats even crazier is that learning how it works takes only a few seconds. Of course it took me 8 years to be brave enough to figure it out. So, hopefully a few of you who do much correction will see this and ask, how?
