How to Enlarge Images Without Becoming Blurry in Photoshop
Hi there in this video, we're going to look at enlarging images way beyond where they should go. We all got jobs like that that somebody says here. Here's a tiny jpeg. I want you to make it into a billboard so we'll go through the different ways of enlarging and the kind of different effects will even show you cool little shortcuts on how to kind of compare them all in three little windows all kind of checking details, deciding which enlargement algorithm is going to work best for us. Let's jump in there now. Alright, let's open up the file in oh four fixing images and it's called re sizing one. Alright, so there is different methods for re sizing. So at the moment this document is 2000 pixels. Remember our shortcut down here, click on this and it says 2000 pixels wide but we need it for a billboard. It needs to be huge. Okay, so we're going to bump it up to like 8000 pixels wide, You might be just doing a little change. Maybe not something this big but um it's under image. That's good...
at image size and in here what we're gonna do is, let's say it needs to be under pixels. It now needs to be pixels, make sure re sample images ticked on and by default everyone just leaves it at automatic. Problem with the automatic is that there's some other settings and they might be great. The thing we're going to do also is just make this a bit bigger. Okay, because it's nice to see it rather than that tiny window. So you've got basically automatic is going to pick this first setting here out of this group. These are all the kind of enlargement, automatic settings. There's just one for reducing And to be honest, like you can test these other ones because it doesn't have to just be for enlargement, you could use this for reduction. I'll just give you kind of different looks and you might find one of these better for reduction but enlargement is generally the most problematic one and the ones we're going to stick to in this video. So automatic is picking this one and that's fine. Even if you do use automatic there is if you switch it to it and say I want to use this actual preserved details. Okay, I can play around with the reduced noise and just kind of decide can you see before after. Okay, you can just have a little bit more control with even that one. Now, a good thing you can do to kind of compare these three, you can just like be super quick and easy and just go actually, I was going to toggle through that one. This one just kind of decide which one is good for you. Okay, so you might decide that this quick, easy and dirty method is just good enough. Okay, and you can just kind of like eyeball it and say because this one here preserve details. 2.0 is the brand new one for Photoshop CC 2018 but it's not default yet, even though it often has a better kind of finish or at least a different finish. So decide which of these works for you if you want. My humble opinion. This one here works better. There's a mixture of kind of like noise but also some kind of sharpening that goes on around high contrast areas. I find it looks good when I get up to bigger sizes. If you want to be a bit more scientific about it, I'll show you a nice little trick. Okay, so I had to cancel what we can do is we can go to layer and let's go to duplicate layer. So I'm gonna make three versions of this. So I'm going to say instead of duplicating this layer, I'm actually going to stick it inside a new document. I'm going to call this one. Option option two. Let's just call option one. Okay, so it's kind of taken that file duplicated itself and call itself option one. So it's just a completely separate. It's the same as doing file save as I'm going to duplicate it three times to compare the three different options. Go back to resizing one back to layer, duplicate layer. New, Gonna Go Option two. Back to the first one and we'll go third option you can go through all of these. Like if you are like man, this is a super important job. You might not just use the enlarged ones. Okay. You might use the reduced ones. That gradient ones because who knows what your content might be. It might be repeating patterns or gradients or or weird trippy kind of three D stuff so have a play around with them all. We're just going to do these three. Okay. And close down the original. So my 12 and three options are exactly the same. I'm gonna start with option one and I'm going to go image image size. I'm going to go 8000. I'm going to just say you are that first option. Okay preserve details, click OK. Go to this option to do the same thing. Image size and let's go to preserve details. Two lets bump it up to 8000 pixels. Okay. Okay. Same thing with three. We'll use our shortcut command option three control option Sorry command option I to go to image size, control option I 8000. We're gonna go to that last option. Okay so now we want to compare them so now you can just cycle through them if you want. You can hold down the command key on a Mac control key on a pc If you're on a Mac now so hold command and hit the apostrophe key. It's generally kind of tied in with that wavy utility key and you can I'm just talking through the tabs. We looked at that earlier if you're on a pc hold control tab I think to move through them and you can just kind of see the difference option one, which is the default option two, option three I find in this case, option two is probably the best. It's a mixture of bit of sharpness but it's not too milky like this last option. Let's go even a bit further to kind of compare the three. So let's go to window and go to a range and we're going to say three up vertical. You might be comparing four options or six of them, Okay, Depending on how many you have. Open. I'm gonna go to this three vertical and it just shows me all three of them here and I'm gonna be on this first option, I'm gonna move it to kind of where the eye is and what you can do then is go to window, go back to that same thing where it says a range and say actually just match all of the zoom location and rotation. So they will match up and then you can kind of start doing some comparisons. Another little shortcut is remember shift and drag around kind of and moved one around. Okay using the hand tool. But if you hold actually I said shift didn't I? So if you hold space bar down on your keyboard and just click and drag okay, you can move it around. But if you hold space but and shift it kind of does all of them at the same time. So first up let's arrange and let's match all. Then we can hold down that shift in space bar and we can just kind of work our way around and just say like okay for the teeth that one the man, I think this one here is the best for my option. There's always going to be pixels. There's this group in here which I'm maybe not happy with. What I might do is start blending a couple of these images, start masking out parts and it really depends on how hard court you need to go here. So my advice is don't listen to me or other Photoshop experts and say you have to use details. 2.0, do the test yourself. It doesn't take too long and then just decide. Yeah, that's the one that works in this instance with this image. Just think of them as option 12 and three. All right, before we go, last thing you might do is go down to window arrange and consolidate all into tabs just to get them all back into like this regular old tab structure that we had before. Alright, we didn't cover reduction mainly because in my opinion, I don't run into trouble reducing images. I leave it set to automatic and it picks this one here and it works fine. But again, if it doesn't for you go through test them all and see which one works for you. All right, that is going to be the end, see you in the next video.
