Hi there, guys. In today's video, we're gonna be looking at adjusting our image to get some better contrast for the C. M. Y. But before that, let's have a quick intro first. So today's video can be found on softwaretraining.co.za. We make short and easy to watch problem solving videos and we also have daily updates otherwise, back in the programme here. So now in the previous video, we looked at removing our K from our C M Y layer and adding a K layer on top with a multiply overlay. So now today we're gonna be looking at adjusting the contrast so we can get a bit more clarity with out having our K. So what I'm gonna do is with our bottom layer selected. Um, we can take three approaches. We've got the basic brightness, we've got levels and we've got curves. Now, depending on the workflow you like to use or familiar with, it might vary, So I'm just gonna quickly run through all three of them so we can have a quick, uh, overview of that and, uh so we see how to go about it. So what we can do is with your layer selected. You'll see we've got this little icon here at the bottom for creating new adjustment, Uh, full adjustment layer. So especially like a black and white little circle. I'm gonna click that. And then the first option we have here is brightness and contrast. Like I mentioned, it is important to make sure your bottom layer is selected. And then you under the properties, you'll see we have brightness and contrast. So now you can simply up the brightness if you want, or lower it and then use the contrast button to create a little bit more contrast. If you, um if that's what you're going for, then you can use this little eye next to it to preview it with it without it. And then you can see if you actually like the changes, I'm just gonna remove that one. Let's look at the next one. Click on the same little button. Now we're gonna go to levels now with the levels. We, um, have this little sliders where we can choose where the black come in, and same with the white so we can drop those ones a bit and then we can use this middle slider to fine tune exactly where we want the level to be. Likewise, you can bring that in and out so you can see we have quite a bit more contrast there without actually dropping the blacks and so forth. It's gonna remove that one. And we look at the last one, which is the actual curves. It's the one I use often. But, um, you might find the levels or so forth a little bit easier. It's gonna scale this up a bit so we can see it a bit better. So what I like to do is just create a little s curve here, pop up the black a little bit, and then you can maybe even consider dropping some of, um, the whites on top if it's necessary. And you can play around with these points so you find something you like. Obviously you don't want to bring too much of the blemishes through, so it doesn't become a muddy image. But, um, yeah, if we go before and after, you can see that little bit of contrast when you find your printing, it's gonna do quite a difference. So I'm gonna leave it on that one. So we have a nice little, um, what do you call it? Um, adjusted image with a little bit more contrast. So we can just preview with and without again. So this is without I didn't do something major, but you can obviously push these values more if you really need to. Uh, sometimes subtle does goes a long way. So and then if I put this back, you can see we have some more contrast. So it just makes the whole image a little bit easier to read, seeing that we don't have black anymore in the image, but yeah, Otherwise, before we head on to finalising this image and exporting it to the right format, Um, I would say if we go here to softwaretraining.co.za. You guys will notice we've got a variety of different Softwares we do cover, and you can also isolate your search on the top and right. But if you do not, however, find the training videos you're looking for, just simply go. Yeah, request the training video, fill in the mini form, and then we'll do our best to try and make that for you. But otherwise thanks, guys, for watching and cheers
