I'm not sure if it works on a PC. Then open PS, open your testing image, go to curves and load the acv. You will get a solarised kind of version of your image that will show you if you invisibly added texture, etc. It's very handy to see if, when f.i. you added a part to a picture, the grain or transitions in the created image are smooth. If ever you want to create this curve yourself, divide the curve square into 5 parabolics thus getting a kind of sinusoid with 4 tops and 5 dips (I'm not sure that this is the right mathematical description since I'm not a mathematician) The result will look like this: http://users.telenet.be/philippe.orlent/wind_small4.jpg If you look closely, you'll see that there is an fault close to the tips of the left hairs strings. > From: Peter Dzwig <pdzwig@summaventures.com> > Organization: Summa Ventures Ltd > Reply-To: Leica Users Group <lug@leica-users.org> > Date: Sat, 16 Jul 2005 11:56:38 +0100 > To: Leica Users Group <lug@leica-users.org> > Subject: Re: [Leica] Testing curve for PS > > Philippe Orlent wrote: > >> Just offering a testing curve for PS to see if your edited picture has no >> anomalities in it (when you cloned, added grain etc).
