Why Work Non-Destructively Part 1
The next kind of major topic in this just source started off now and then well after a break we'll kind of get into more meat but is this whole concept of working non destructively as I mentioned before, a lot of people you'll hear people say all time work not destructively. So what does that mean and why is it important? Well, what it means is try and do things in a way where you're not making permanent decisions for example that could be a simple as I go to use the crop tool well by default let's just make sure we don't have any pre set in here s o by default when I'm using the crop tool, aiken say all right, I want a crop it like this and the top here says delete cropped pixels so that means when I hit enter and if I had saved this would be my new photograph period unless I had another version of it somewhere I couldn't change my mind if I uncheck delete crop pixels and hit enter it looks like it's cropped, but the difference is even after I say that if I realize I probably should h...
ave done that, I could go back to the image menu and choose a command called reveal all which shows everything else, so they're used to not really be a simple way to do non destructive cropping, but now there is here's probably the example that I show every time, because I think it probably shows really most obviously the difference between working non destructively and destructively and that's this menu here, I wish there was a way that this menu just wasn't there because the fact that is there I don't all suggests you should use it because why wouldn't you if it's under there but honestly, all of these things it maybe they just need to change the name of this too destructive adjustments and that people go wait should I really use that? Because here's the difference let's say we wanted to a justice photograph using level so I just went image adjustment levels. This big levels dialog box opens up and I'm gonna overdo it to make a point pretend I was staring into the beautiful seattle son my eyes were all out of whack and I went, there we go that looks much better and I click ok and worst of all, I saved it. I won't actually save it, but if I did the next time I open this file that's it those were my new pixels because I have changed the pixels permanently that's not a good thing, and more importantly, perhaps, if you just go back and say, oh, well, what I just go backto levels again yeah, if you ever see this is called a history graham, this little chart in here give her cia history grantman levels. It looks like this imagine says good luck right up there because something like that means there's nothing to work with. So you've got nothing to work with, so that would be bad all the way around. So in contrast to that, if I go to the adjustment layer called levels right away, there's a difference. First of all, it doesn't open this big giant panel. It just kind of floats around in the way it's off to the side, but more importantly, and this is the probably most important part of adjustment layers. If you look really closely at this adjustment layer, you'll notice there's one thing that's not there compared to the other levels and that's. Okay, with an adjustment layer, you never click. Ok, there is an ok button. You just leave it. So when you're making an adjustment, you move a slider and when you're finished, you just move on and do something else. So if I say this document, the next time I opened, it would look just like this and I can go oops, that was bad, and I could just move it back where it was. So an adjustment layer is almost like it's in constant preview you're never going oh well, I have to make that ok now like click ok and make that in any way permanent because it's not so I always suggest people the simplest way to start thinking about non destructive is can I change my mind? And if you apply levels or kurds are and those other adjustments directly to the background layer and click ok and clothes and save your done there's no going back. So when we talked before about changing keyboard shortcuts, one of things that I would consider doing if it were me today it is is I would look at all these keyboard shortcuts for like levels and curves, which are standard and change that keyboard shortcuts so when I pressed commander control l instead of getting levels, I get levels of justin player so that would force the issue to say, don't give me don't just run levels on my document, make sure it's an adjustment layer so personally I highly recommend that with very few exceptions you don't use the options under this menu because by nature they want to be destructive they want to change things in a permanent way that make your life more challenging now there's always exceptions if you open a photograph here like ansel too dark, I want to move this click ok that's all right I suppose, but for me there's a little voice in my head going, yeah, but what if you just don't know? I just don't want to take that chance. So for me I'm going to get this wagon do adjustment, layer and here's the other key part and say this as a psd file adjustment layers mean nothing unless you then say that is a psd to preserve the two layers, the original and the adjustment layer. So then the next time I opened this, it looked just like this with a layer that aiken double click on a go oh, that's the problem I need to switch this like this, dave, I just I have a comment from the chat rooms and this is the part that I love about the interactive nature of our live events. And that is from, uh, from bp photography says when we're talking about the renaming or I'm sorry altering the workspace he or she says, if you name a workspace preset the same as the existing one it asks you if you want to update the pre saw, you know there's a simple way exactly, but it has to be the exact same what makes sense, thank you very good so this is probably the I guess that I always start with this example of being non destructive is because right away it shows you why we do it this way because a I can change my mind, I can say ok, I don't like that I could either hide it completely or I can re edit it or as we'll see later, I can use the layer masters, they only apply it two other areas, but the other reason why it's a good idea to do this is because let's, just pick this one for the sake of argument, what if you have another photo to say I love that adjustment so much? I want to exactly the same one on the other photo. So instead of having to go in somehow figure out what settings that I use, I can take this adjustment layer and just drag it onto the other photograph and then that once adjusted to so from a the other part of working non destructively I think is so important is the repurpose ing ability to say I want to take this same thing I've already done and use it over there. I had a discussion with come brother photoshopped folks some time ago and we had a friendly discussion on the merits of working non destructively, and this other fellow was saying, you know, but a lot of the time, I'm not going to change my mind. I'm not doing the work for a client, so they're not going to have any input I'm just looking at a photograph and I decide I'm going to make this change save it, I'm done and he said so in that case I don't really see the advantage of working non destructively I said on fair enough but the other hand what's the disadvantage of working non destructively and to me the only one I can think of is your file size mike a little bigger, but why wouldn't you want to have that backup because at this moment in time you might think I don't need change my mind, but what if someone you decide a year later I wish I had a version of this where I could whatever fill in the blank to it now you do and the other thing I would remind you we have this you asked the question before bob about saying about looking in the history if you open a document, you see three adjustment layers and a mask and this and that you can sort of break it down and go. All right? I started with this and so that's the other advantage of the whole non destructive way of working as you can look at a new image later look at the layers panel and kind of do that same reverse engineering thing and say right eye made a black and white. Just blair and I paint on the mask, and I changed the blend mode, and you kind of break it down that way. So that's. The other advantage of it is. It gives you the ability to go back later and kind of revisit what you did and see. How did I do that? And how can I use that other parts of my dock? Your other images as well?
