Q&A: Sharpening

We want to take any questions on sharpening anybody have any sharpening questions? Go ahead, smart layer question um, once you've done the sharpening in the smart layers, um, say I see like a stray hair or something, and I want to just do like a quick patch or like a healing brush or something, none of my stuff will work like when you click on him, right? You're healing tools will not work on a smart object because you're healing tools are actually missionary on pixels, and that can't happen to a smart object, so you would have to rast arise it at that point, rast arising turns the smart object back into a regular layer. So would you retouch before that and then turn it into the smart object or do it after you did the process of, uh, sharpening their those types? Well, what I typically do is I do my color correction, retouching, special effects and all that before I sharpen. So if you follow that workflow than all of that kind of pixel, manipulation will be complete at the time you're ...

ready for sharpening so you could take your whole layers panel, you know, if the if the image that you're working with is comprised of several different layers, you could turn those layers into a smart object. Just activate all of them right click or control click over here and say convert a smart object and then you can apply your sharpening tio a slew of layers at one time but theoretically sharpening at least in my work flows though is the last step you could if you needed to do some last minute touch ups couldn't you do that on a blank layer above yes you can in fact we're going to be using our healing tools on empty layers when we get into that in a little while yeah so that would be another way around if you know if you didn't see that straight hair or or stray blemish until the very end then he could still fix it yes sir I read somewhere that for commercial work you shouldn't sharp on you should leave it to them to do those tweaks what do you think about that? It depends on how much you trust the person who's out putting your files I would sharpen them myself I mean analysts you know your client or whomever is telling you specifically not to but I would still do it I have a question from paula joe who would like to know if I have a nice pok going on in the background of a photo would global sharpening in uncharted mask hurted if you have so a soft back room global sharpening is going to sharpen it a little bit that if you you know, if you pump up your threshold a little bit, if you're using and sharp mass, then you can keep it from affecting, you know, pixels that don't have very much contrast, which a blurry back room is not going to be high contrast, so I would say, use on chart mask, pump up your threshold a little bit more, you can really go between three and twenty with that control, so I would pump it up to keep it from affecting those pixels, and even if it did, he could still hide it with the mask that comes along with using smart filters. We've had a couple of questions about how thie resolution of the image relates to sharpening, so when you were going through some of your examples of the numbers, somebody had cats itis what size images are these shepherding formulas referring to they seem little rest me? What does she suggest for high res images? One hundred fifty or three hundred p p I, and then still still allen in dallas, still out in dallas, asked, doesn't radius depend on the resolution of the photo? So is there any kind of correlation? It's it's less a question of resolution? Because if you remember, resolution is only the measurement that determines how big or small the pixels are, ok, what really comes into play here is how many pixels you're working within the image. It doesn't matter how big or small they are because, you know, on the screen, you're only going to see them at a certain size anyway, you can't see high resolution on the screen, so it's not a question of how does resolution change those numbers? It's a question of how does how do you pixel dimensions changed those members? So those numbers are are pretty it? I mean, unless you're shooting with a like a cannon five mark d or whatever the heck, the latest and greatest, you know, amazing full sensor camera is full frame sensor camera is I feel like these numbers are going to work for you. Of course, they're just guidelines if your image doesn't look sharp enough to you, then you can, of course, increase them, so you may have to bump up those numbers a little bit if you're working with an image that's, you know, five thousand some odd pixels wide by thirty forty, two hundred, somewhat pixels tall, so the more pixels you have in the image, you might have to increase those numbers a little bit in order to see the sharpening but it's not it's, not really a question of resolution question from still al in dallas since you need more sharpening for printing versus web, would you have a separate file or another sharpened filter that you can that can be turned off to print? Turned off to print? You could you could duplicate your smart object and add, you know, an extra level of sharpening for print if you're preparing the same image for output in both weighs like if this image needed to get on the web and it needed to go to print and then I could, you know, create another. I could do another level of sharpening on another smart object. I could either duplicate this smart object via copy, so it doesn't link it to my original, and then I might apply a little bit more sharpening for that and then just talk with the visibility I often on of the one that I was saving, so you could certainly do that question from glen h w t does global change change the second smart filter? Does global change the second smart filter? Does global change change the second smart filter? And I think that was maybe when there are. Yeah, if you have applied global shark means to a smart object in youth been turned that into a smart object and even applied selective sharpening if you go back and edit the original. Smart object where your global sharpening was, then yes, it will change the amount of scharping that's going on in the second smart object, but on lee in, you know only as much as you're changing it back in that original smart object. So, yeah, I will update the changes in the second smart object. One more question, ok? Canadian gumboots has asked if you're using a high pass filter and you and you don't want to apply the filter to certain areas, what he would you use gray or black to conceal black? Black conceals white reveals you do have you can use gray in your layer mass, but if black conceals and white reveals, gray is goingto do a little bit of both, okay, so it won't hide it completely. So that's another. Actually, I'm glad that he asked that question, because if you if you just want to tone down sharpening in a certain area, you could paint with gray in the layer mask, whereas a painting with black would hide it completely. Maybe you don't need to hide it completely. Maybe you just need to tone it down a little bit, and he could paint with gray inside that filter mask to accomplish that.
