Noise Filter

So now this is the effect we're going to create so if I zoom in a little bit and this is ah higher is image that I have given you here because I really wanted to be able to zoom in on screen to show you this effect so here's the before and the after this is pretty severe, but I think it's one that is useful it's one of the most beautiful half tone effects that I've seen it's derived from a technique I learned from scott valentine actually has a fabulous but just on blend modes and I think it is just called blend modes and this technique it's similar to one that he had in that book and I don't remember the contributor's name because it was a book that he put together they had a bunch of people contribute to but this is a great use for the noise filter and the blur filter, so I'm gonna turn off the layer that I made for you and as you can see it creates a quite a unique look. So the first thing we're going to d'oh is create a new layer that set tio blin mode called hard mix, which is goi...

ng to reduce all the colors and the image down to primary colors so let's go ahead and add a new layer but in a different way that we've done before, so we're going to press shift command in for new or shift control in for new on a pc and from the mod menu, we're going to go ahead and choose hard mix, which is down here in the overlay category and click ok the next thing we're going to do is fill that layer with fifty percent gray, so we're gonna try out to the edit menu choose phil and from the eu's poppet menu you're going to choose fifty percent break is isn't that handy? It's an option? Click ok, great! We're done that's keeping that the effect of hard makes right there reduces your colors to primaries, which is kind of wild anyway, we are not yet finished now we're ready to run our filter so let's go up to the filter menu and you could do this with smart filters as will burn and choose filter noise, ad noise skate this whole dialogue up so you can see it you're going to add on a male anywhere between fifty and one hundred percent let's shoot for the middle of just seventy five and you want to make sure in turn on gaussian for distribution and turn on monochromatic so that we're just introducing black and white noise, not colored noise, so go ahead and click ok, now we're gonna add a blur filter so let's go back to the filter menu choose blur, gaussian blur and we're going to enter an amount somewhere around two, three, four five so kind of a small amount we'll shoot for five for this one, so we're just going to blur that noise a little bit. Now, the last thing we're going to do is we're going to lower the phil amount, not the opacity, the fil amount because the phil is going to affect what's on this are the spots in the speckles it's really going to drop the gray out it's what's going to happen here? So let's, go ahead and lower the phil amount and you can experiment with this so usually for this technique maybe between fifty and seventy five percent of a fill level, but isn't that beautiful let's just appreciate that for a second and that nice it's different so there's the before and there's the after another great technique to have in your bag of tricks. If you've got an image that you just can't seem to get the color to your liking on so let's zip through that one again so vast it really is an easy take me, so we're going to add a new layer so we can just use the new layer icon at the bottom of the layers panel and then use the papa mini for blend modes at the top of the layers panel and we're going to set this new layer tow hard mix now we're gonna fill it with fifty percent gray such use edit phil cheese fifty percent gray from the eu's poppet menu click ok, now we're going tio run the noise filter filter noise, ad noise this is really the only place we have to remember a whole bunch of settings so you want this amount somewhere around seventy five percent you want to turn on gaussian and turn on motto chromatic and those settings will stay that way until you change them and at some future point in time, so click ok go back to the filter menu she's blur, gosse ambler we're just going to blur the noise a little bit and here you're going to enter a pixel value of around five for larger documents, maybe more the higher value here, but this is a pretty big document, so five we'll probably see you just fine. Click ok, and now we're going to lower the phil not the opacity, but the phil and we're going to lower that to an amount that looks good to us, which will be somewhere around the fifty percent range and it's just a beautiful technique that I think he can sail in your photography business. Yes, how could be used to fill setting instead of the capacity like what's the difference between the two? Well, the phil works in a little bit of a different way than opacity opacity would drop the capacity of the whole layer so cia's we drop opacity not really much is happening here we're dropping opacity the whole layer but what we really want to do is drop the opacity of the gray bits and that's where phil comes in so if you've got anything on a layer see gray is unusual color in this particular blend mode so when I dropped the field it's dropping the gray this out of the image so we're really only left with some of the color so it's dropping a little bit of the layer content out not all of it one of the the best ways to experiment with a difference between filling capacity is tio ad cem at a shape layer to your document and put a stroke on it and the field color and when you dropped the phil then your stroke is still one hundred percent invisible so another example of that would be on text actually we can just do it on a shape player real quick so I'll grab a shape player and I'll make it oh fill it with orange and then we'll put uh a red stroke on it will make the stroke nice and big so as we click and drag here on our document if I zoom in you can see that oh we've gotta fill and a stroke or an outline well, when we drop the opacity, we drop the capacity of the whole mess. So everything that's on that layer. But phil behaves differently, and it on ly drops what's inside of it. It's, a little bit more difficult, understand in this particular layer, because we've got neutral color going on. We had a noise to say, we've got a lot of different colors in there, so it's behaving a little differently, but that's, basically the gist. So fillon opacity are different things there.
