Hi there in this video we're going to look at what image resolution is or D. P. I. Or P P. I effective PP I basically it comes down to the quality of your images. Let's go and do that. So image resolution might have come up in your world before and you might be like oh I can't understand it. Maybe I don't, maybe you've never heard of it. Okay so let's have a quick little look at what it is, resolution is basically the quality of an image. So I'm going to click on this background image here. Okay. I'm going to go to my links panel if you can't see links, go to window and down two links. Okay. And we're going to do is you might be able to see it already but I don't have mine activated. See this little area has is higher. Show hide link of information. Okay. I'm gonna make mine go up a little bit higher. Just so I can see a bit more of this link information. You can boil it down. You can make a bigger Okay? And it just gives you information about the image. So there's the name, it's a jpe...

g. It's on page one. It's RGB. What we're really looking for is this one the major one is the effective P P I P P I is an acronym for pixels per inch. If you've ever heard of D. P. I. Or dots per inch is exactly the same thing. Just a new way of explaining it pixels instead of dots and we've got targets to hit. Okay so the effective PP. I maximum should be about 300 that's going to give you amazingly beautiful crisp clear image when we print it and the lowest that we can go is variable. So it comes down to what its purpose is. If this is going to be printed commercially through an offset printer and then put out an hour display case at our showroom then we want it to be as close to 300 or above. You can have and that's fine. There's nothing wrong with that. Above is good. Below is when it starts getting into the gray area so 300 is the target. It's totally just a made up number. Okay that looks really good. Some people use it like some sort of like carved in stone can never be changed number really if you're close to 300. Okay like this one is here this is 2 91 I would not care. Okay there's probably pre press people out there that might can go be going kind of a red kind of color now but if we're all honest we've all printed stuff below quality and nobody has noticed the difference. Okay so it's how low can you go? And what really happens is it's depending on how big you've stretched this image. This image is you can see it's actual PP. I is 300 so it was a 300 D. P. I. Image or PP. I. Image but I had to stretch it a little bit bigger to cover the bleed. So I just made it just a teensy bit bigger so it reached over this bleed here. So let's look at an example that won't work. Okay. So I'm going to delete this guy in the background temporarily. Okay. I'm going to go to file place and I've got an example in 03 newsletter, grab that one and let's go to image resolution example. Okay I'm gonna bring it through and I'm going to Bring it in. Okay? I just clicked it once and that's come in and it says it is 72. Okay, so which is going to commercial printer is not going to work. Okay. So it needs to be at least 300 but it looks okay on screen. Okay, so if you were going out to a screen okay as in it's going to be emailed or downloadable from your website, 72 is just a fine old size. I'd like it to be a little bit higher but the minimum is 72 to look okay on most screens on a retina screen, like this Macbook pro that I've got in front of me. It'll look a little bit pants but I've got to stop using the word pants. It's UK slang for bad, like underpants, not bad. Anyway. Anyway, back to resolution. So it is 72 dots per inch or PPI PPI I pixels per inch. So it's going to work for a screen but it's not gonna work for print but let's just say let's just make it bigger. I want to use it for the whole cover so I'm going to make it quite big. Okay I'm gonna make it nice and big so it covers the bleed, I'm gonna trim it up there and it's looking okay right it's like it looks kind of fine on my screen now it might look okay on your video but it will print really badly and you can see if I slipped on it. The effective PP I is 300. Now why is it changing its because I'm scaling it up. Watch the effect of P P. I as I keep scaling it up, Scale it up, let go. It's 28 it's kind of stretching those little pixels because if we zoom right in it's actually made up of little squares, that's what resolution is or pixels per inch. Okay this this is a pixel and how many pixels are in an inch at the moment. There's only 28 in that inch. You need a lot more dense pixels for this to work. You can start to see now it's looking a little bit ready around the outside pence even. Okay so the main thing to look at is don't worry about the quality of the image that came in first back in the days of your you had to make sure everything was 300 PP. I before it came in. What you can do now is we're just looking at effective pp. I ignore this number here, what it is here. So if this is going out to commercial print this is so far from 300 that it's not going to work at all. Now what are the boundaries? Say I do want to use this commercially? Okay I'm going to scale it down, you can see 78 still too little. So if I want to use this in commercial print and I want to use it at G. B. I can see him getting there. 1 38 might move this across so you can see it closer getting smaller. 2 to 7. 312 close to it. Okay so that now is the right resolution to be printed. Unfortunately it's teeny tiny. Okay so if you've downloading images from the Internet you just got to make sure they're really big. So you can lease when you scale them down you get close to 300, how low can you go now? This is total personal preference. Now now the rule is 300 but I know if it's a good quality image from like a stock library site you can get down to about 1 80. 1 50 if you're really sneaky and it will print fine. I probably wouldn't do this for the front cover because it's such an important part of this document but say it's an image that's on page two and it's just a small image and the resolution is about 1 80. Nobody will notice again. It really depends if you're trying to sell Bentleys and you've got some low quality images that are just slightly off, I'll be looking for 300 above for resolution but in the general day to day world 180 works just fine for me and to re crap if you're working on screens okay that means it's going out via digital means it's going to be emailed or via downloaded from our website, 72 is the minimum a lot different because screens deal with resolution a whole lot better than when it's printed physically. So if that's the case I can have this all the way up at 54. Not quite that much. We're getting close 59, come on Dan you can do it. Okay, 71 72 that is fine. If it is physical size, that's going to be a digital download. So in summary, just make sure your effective PP I is between 72 and 300 depending on its purpose

I think Dan is very good at explaining and breaking down complex content. I like the way there are lots of small sessions which is good for keeping focus. I would advise anyone who does this course and is taking notes to label which session the notes are referring to as I have struggled to find a few looking back and this helped me. It really made me realise how much I didn't know and had been fudging. Thank you Dan I will be taking plenty more of your courses in the coming months it's been a great help.
