Re: Basic Digital Negative Curve Tutorial
That part is a little touchy-feely. I start by working my way left to right and dividing the spline in half each time I put a set of anchor points down. Sometimes I'll put more points in an area if the curve has a bump or a dip. Generally, it seems you need more anchor points on the left than the right. Do a couple and you'll start to get a feel for it. Good luck. ~m ----- Original Message ----- From: "Laura Valentino" <laura@this.is> To: <alt-photo-process-l@usask.ca> Sent: Tuesday, June 26, 2007 5:55 PM Subject: Re: Basic Digital Negative Curve Tutorial > Hi Michael, > Thanks for this!
