Hi I’m George Peirson. In this Photoshop Elements video we’ll be talking about the truth behind increasing the resolution of your pictures and why you can’t go from a picture like this to a picture like this it just cannot be done.

And if you want to help this channel keep on going take a look at my complete training courses and you’ll find a link right down there in the description. Okay, let’s get to it. [Music] I’m sure you’ve seen videos online where the thumbnails suggest you can go from this to this. Now the basic truth here is that you can’t do that, just cannot happen and that’s because at this pixel resolution we don’t have a lot of details. These little fine hairs in here, they’re not over here there’s no way to put those in. Elements or even Photoshop doesn’t know what’s missing. It doesn’t know how to put that in. We don’t have the nice hard edges on the teeth. They’re just not here to work with. We don’t have these highlights in the eyes. They’re just not there to work with. So you can’t put in details into a picture which doesn’t have those details. So we can never go from this over to here using the standard technique to up-res an image. Actually can’t do it at all with any technique but you can get rid of the pixelization problem in here and improve this to make this bit up you just can’t get over here so let me just show you the standard technique we’ll be doing it on this image here which is a real low resolution image and then I’ll show it again over here on this image this one is that 72 pixels per inch kind of a standard Internet image and we’ll up-res this for photographic use and you can do that and it looks pretty good but we’re already working with a sharp image so we’re okay on that let’s see what happens over here if we actually took those other videos at face value who said you can take this and turn this into this and I’ll show you what happens when you actually try that we’ll use the standard technique and that begins with going up here to image resize and image size the first step is to start with the resolution lists changes out to a printing resolution which is 300 PPI or pixels per inch the next thing which is normally done with those videos is to double the pixel dimensions up here I’m going to set this at 4000 which is a bit more than double let’s make it as nice as we can here here we go so we are increasing the resolution and increasing the pixel dimensions up here as well now make sure the resample image is selected and down here this little drop down set this best for enlarged this will let the Adobe algorithms do the best job they possibly can at making these adjustments ok choose ok and I’ll now zoom this back out to fit on screen so there you go actually it it’s not that bad considering where we started from we’ve gotten rid of all of that pixelization effect and there’s there’s Norfolk civilization but notice we have not put in any details so anything which was missing any missing details cannot come back in again we don’t have the sharp edges on the teeth we don’t have the sharp edge over here we don’t have the highlights in the eyes we don’t have those little hairs up there because those were not in that original picture we can’t add those back in again but we can get rid of the pixelization effect so it will do that for you that technique will get rid of that peaceful ization for you but you get a soft and blurry picture I’ll show you technically exactly why that happens in just a little bit if you want to dig that deeply well go ahead and we’ll go that deeply just a little bit in this video let’s see what we can do here though the next standard step on this technique is to go in and run a noise filter to remove any noise in here so as filter come down to noise and reduce noise brings up our noise filter here I’m just going to zoom out on this a little bit that’s about the same size looks pretty close ok and with this one you have these three options you can reduce color noise in here if you have any jpg artifacts this is also will cause kind of a pixelization look but this would have been solved already with our first pass over there so you can not worry about this now whether or not you have any color noise in here will depend upon how bad your pixelization was over here and how about your JPEG artifacts were originally so at this you can adjust this to check your strength and you can preserve details now if this really does is it comes in just this kind of softens up edges is really a blurring filter it’s kind of a smart blur info but it really is a blurring filter there isn’t one you’re not really seeing anything happening here is because this picture is already blurry so this is not gonna be doing a whole lot of good for us with this image over here this can help sometimes again depending upon your image if you’re getting some weird things happen and this can’t help to remove some of those but for our use it’s really not giving us anything here is preview before you in and out and there’s just nothing happening okay so that’s the normal second step on that now I think that can occasionally be useful but it’s not really the right step that’s next the big problem with this picture is that it’s soft focus it’s a blurry picture obviously if you want to get rid of a blurry picture you want to increase the sharpness we want to sharpen this picture up if that’s possible now it’s sharpening does is it looks for contrast edges and increases the contrast on those edges so we can make it look a little bit better to the eye but still we can never get this over here on the right hand side let’s take a look at its what that is go to enhance come down to adjust sharpness and again all back this out to her about the same size that’s pretty close in there there’s before-and-after I’ll just preview that so a little bit of sharpness actually does seem to help a bit I pull this up see it looks a little bit better in there there’s before it after and what it’s doing is again it is increase in the contrast look at this this highlight along the edge of the face right here it’s less there and it’s more here so it’s really pushing those contrasts on those boundaries and the contrast on the boundaries makes it look as if it’s a sharper picture again it’s not bad here’s the after there’s the before so you can by using a bit of sharpness after you do that image resize trick you can come in here and make a picture look a lot better than it was but it’s still not this we still don’t have those little details in there you cannot bring those little details in if they weren’t there in the original picture so that’s about the best you can do again this is not bad I mean this actually is pretty good considering how pixelated it was this is a vast improvement but just be don’t be fooled by those other videos where they show those really pixelated things and they’ll show you one of these things as you’re after it can’t be done okay so that’s taking the worst case scenario and kind of debunking a lot of those thumbnails that I oftentimes see on videos and just get rid of that one not gonna bother saving that come to our grid in just a second let’s look at this process over here on a more realistic situation this image is at 72 PPI pixels per inch kind of standard what you would expect for a an online photograph if we zoom in on this so pretend the edge for a finger you see we have some pixelization in there on that edge so we do have some pixelization yeah a bit here a bit up in here and we can minimize that effect as you saw we can really hide pixelization pretty easily by up rezzing the image but it’s only going to work if you’re pixelization is this small this fine on your image already so you know massive pixelization it can’t fix they real fine stuff the technique will give you the higher resolution to see how it works over here on this image again let’s go up to image resize image size once again same trick change your resolution to 300 and then double your pixel dimensions I’ll put it to four thousand exact same thing we did before and let’s change the resample image technique down here to bicubic smoother best for enlargement choose okay and then back to fit on screen and if we zoom in now on that finger it has smoothed the edge down notice all the finger is still blurry along that edge we haven’t increased the sharpness we have smoothed it out so that resize technique gets rid of the pixelization effect but it adds a bit of blurriness it doesn’t get any sharper it just gets less pixelated but again for this kind of an image that actually is fine this is now at 300 pixels per inch so I wanted to use this in a different project that was at 300 pixels per inch this would solve that let’s now see what happens if we sharpen this a little bit using my technique again I don’t like using this one noise reduce noise that really does not work for me that’s not the right way to go because the problem isn’t noise the problem is sharpness so the next trick here is enhance come down to adjust sharpness and let’s just zoom out a little bit here see there’s the there’s the finger now you’re seeing a real difference in here and is really increasing our contrast let’s just back off on that amount bring everything way down to the to the basement down here bring the radius up just a little bit and then bring up our sharpness just a bit and this is increasing the edge contrast and by increasing your edge contrast it gives you the effect of it being sharper so let’s just preview this in not not already seeing much of a change yet let’s go get further now I’m beginning to finally see it you kind of see it right up in the eye in there there’s before and here’s the after now again it’s not adding in more details just increasing the edge sharpness and if your detail is small enough if your pixels are small enough to begin with it can look like you’re getting more detail even though you’re not actually getting more detail so there you go that is the proper way to increase your image or increase your resolution and to fix into that softness again it’s by increasing your edge sharpness using the adjust sharpness tool to bring that up I have these so close to halfway up on this particular picture it’ll depend upon your picture what the actual settings are put them both to the bottom and then kind of move them up like that going back and forth and take it a nice setting if you click and hold you see the original if you let go you get your sharpened version in there and then choose ok and there we go so there is the upraised image we’ve increased the sharpness and it looks like there’s more detail but again there actually isn’t it’s just sharper edge contrast but that’s perfect that’s what we need so there you go that is the right technique for up rezzing it is first to change your resolution by using image resize image size right down here double that up there and then that’s for smooth gradients that’s your first step your second step is enhance and adjust sharpness now give you the best in largeman and you look pretty good I think you’ll be very happy with the results if you’re going from a standard internet image say at 72 pixels per inch and you’re going up to a printed level image which is at 300 pixels per inch this will work out really nice ok so there’s the basic technique and if that’s where you cared about there you go now if you are really interested in what’s really happening in here see how this is actually working I’ll do that demonstration here next let’s just close that out I’m not gonna bother saving that one okay to really see what’s going on I made this grid you know this is just quarter-inch grid and I filled it in with these black and white checkerboard pattern this represents the detail in a picture and this is set at 72 pixels let’s double check that resize image size and we’re at a resolution of 72 pixels per inch now if i zoom into the corner up here way into the carnal go all the way in on this well let’s pull my zoom control here clear to the top that’s as far as it will go there we are and let’s move that up a little box right there this is the exact pixels so that’s 72 pixels per inch that’s exactly one of those 72 that’s your second of your signature third of your 72 and so forth so this is the exact pixel size right there on this image now we have this we can see what’s actually happening if we up res this up to 300 pixels per inch it’s kind of interesting little demonstration now the beats hard edges here the heart is in the heart is edges over here on our big squares this represents your detail the level of detail you have in your picture it’s those hard edges that’s your detail okay image resize image size same thing again exactly the same thing it’s even the same size as you can see up here so let’s set this at 300 the exact same thing as before let’s change Alif to a little bit more than double I’ll set it at 4000 exact same thing we did before let’s set the enlargement here for best foreign largemont spike you look smoother choose okay and there we go that’s what we get on this thing now I’m gonna make sure we’re zoomed all the way in there we are that’s a full zoomin and so this is that little section up in the upper left-hand corner that’s what we’re seeing there we zoom out just a little bit help just pull this back a bit so you can see that there we go now we’re seeing it so when we did that it took those individual pixels see this was one pixel here that was one pixel that was one pixel and a tree divided that into smaller pixels and we did it at 72 up to 300 and then more than doubled that when we went from 1,800 to 4,000 as our pixel dimensions so we basically into about a little more than 600 PPI realistically speaking and what it does is it takes that and just kind of blends that out so i zoom up here this was black this was white this was black white black white and so forth so it took that n divided that up into smaller dimensions and you can see what happens here we’ve lost our contrast in here on the edges it has given us a lot more divisions now so that has smoothed out the pixelization we’re no longer seeing our pixelization in here it has smoothed that out we’ve also lost that edge contrast that’s why first this technique does give it over pixelization effect is really smooth that out you can’t really see where those dividing lines are any longer we’ve gotten rid of that but also shows you why this sharpening technique improves it because it increases the edge contrast and helps push things back to where they were to begin with but not all the way let’s do that but first this is going to scroll over here to the right hand side this is that that first big black square here’s our first big white square and see again the divisions in here it subdivides that division so you no longer see that hard edge that hard edge is what causes that pixelization effect but also that hard edge is what gives you your details so it tends to soften a picture down when you do that when you use that enlargement and that’s actual what’s happening here it softens down that those edges so you know largely your pixel dimensions will tend to soften the image up that’s the main thing I wanted to show here you’re gonna lose detail you can then gain that back the appearance of that back by going in and increasing your edge contrast to see how that works that was enhance adjust sharpness and me back this out so we can find that edge in here so I’m on the wrong layer right there what I’m going to do is I’m going to merge this whole thing this just right-click in all merge layers so it’s all on one layer that’ll make that control easier to see so enhance adjust sharpness there it is so here’s our little square up there that’s what we’re seeing in here and here’s that other our big squares so you can see how the edges have become soft in here we’ve lost a little bit of detail we’ve lost a little bit of detail up in here if I preview this tool so this clear to the bottom there we go and as I bring this up and then bring up my radius a little bit you can see what’s happening now it is beginning to increase the contrast in here so we’re still soft on the edges but the contrast is getting larger the blacks are going more black the whites are going more white and that what is what gives us that effect of gaining back our detail we’re just increasing our contrast we’re still not getting back that pixelization because the border here is still soft still a nice soft deep pixelated edge but the contrast increase makes it appear as if the image is sharper so that’s what we have going on here so if you look at your edges in here if I hold down that the original lick oh that’s our preview so it appears that we’re getting more detail in here we’re actually not gaining anything we’re not gaining detail but we are is restoring some of the detail that was lost at least the edge contrast that was lost we did our enlargement so there does that’s the whole technical side of this whole bit kind of confusing here possibly but that’s what’s actually going on with the enlargement and also with the adjust sharpness so you doing that kind of an enlargement on your image you want to first start with doing the pixel dimension increase and then you’ll want to do a sharpness increase to make up for the loss in sharpness and most of the loss as you can see here these are long real gray the loss in contrast on that let’s go ahead and take a look at that one more time and bring back up my original image here there we go there’s the 72 pixel per inch image looks good but it is only at 72 pixels per inch default 6×4 size that I always use here on these videos there it is there’s the image at that size if we zoom in you’ll see a little bit of pixelization on the edge of your finger right there let’s collect the fit screen the proper way to increase your piece of I mentions and fix any softening again it’s real fast once you get used to this image resize image size here’s where you set your resolution at 300 and you set your width piece of mentioned with at about double actually 3600 I’m just going up to 4,000 for these things make sure you set this for Best Foreign largeman and okay it’ll larges your image back to fit screen and then that also softens your edges up a little bit and you can compensate for that softness that was what those squares going gray that we saw over here that’s this softening there you can compensate for that by increasing your edge contrast you that with the enhance adjust sharpness let’s bring this back down again looks pretty good right there so there it is with that edge sharpness increase which we use this is the exact same settings I used on that black and white checkerboard grid so there it is without and there it is with but again now you’ve seen what’s going on over here at the grid you understand now that this is not putting in more detail but it’s actually increasing the contrast along the edges of those pixels and that gives the effect of bringing back in detail and sharpness so there does that your technique image resize first and then use the enhance and adjust sharpness don’t bother with what the other videos say which is the goal here and use the noise and reduce noise that’s the wrong approach this actually softens things up it increases the blurriness of your image puts back in more fuzziness you don’t want that you want to sharpen and that’s with the enhance and adjust sharpness so there you go cover several bases here in this video we looked at why those thumbnails are bogus we looked at how to actually do the up res for your image to get the best results and we also looked at what’s technically happening in the
