Actioning a consistent image resolution

Video: Actioning a consistent image resolution

In this movie, we'll further modify our action, to take into account a wide variety of images. And that way we'll be able to use the action to batch process an entire folder full of images at a time. And part of that is about nailing down the resolution value. Because after all, the whole notion of sharpening for output goes out the window if we don't have a fixed resolution. Because otherwise, we don't know how big our halos are going to be. So I'm going to start things off by grabbing these panels right here and putting them back in the icon column right at the top.

Actioning a consistent image resolution

In this movie, we'll further modify our action, to take into account a wide variety of images. And that way we'll be able to use the action to batch process an entire folder full of images at a time. And part of that is about nailing down the resolution value. Because after all, the whole notion of sharpening for output goes out the window if we don't have a fixed resolution. Because otherwise, we don't know how big our halos are going to be. So I'm going to start things off by grabbing these panels right here and putting them back in the icon column right at the top.

And then I'll click on the little Play button to bring back my Actions panel. And I'll go ahead and twirl these guys closed, because we're going to make yet another action in just a moment. But first, I'm going to go up to the File menu and choose Browse and Bridge, and this of course assumes that you've gone ahead and installed Bridge independently using the Creative Cloud utility. And notice that I have Bridge trained on the content of the South of France sub folder that's inside the actions folder. And we have here is the total of 15 different photographs that I really understand what's going on.

I need to see some additional information. So, I press Ctrl+K or Cmd+K on a Mac to bring up the Preferences dialog box. And then click on word thumbnails to advance to the Thumbnails panel. And let's go ahead and change this first guy to dimensions. And then it will automatically turn on the Show check box. And you can now see the dimensions in the background here inside Bridge. And then change the second option to Color Profile, and then click OK. And now we can see in addition to each one of the file names, we can see their dimensions and we can see their profiles.

And notice that all the physical pixel dimensions are exactly the same 2360 by 1040. And all the profiles are set to Adobe RGB, but the resolutions vary all over the place as high as 300 pixels per inch and as low as 72. And also we have some flat JPG files as well as some layered PSD's. So we are going to have to figure out a way to address all these images uniformly. So what you want to do, is, go ahead and open up one of the PSD files. Doesn't really matter which one. I'm going to grab Glanum ruins here.

And now, I'll go ahead and Zoom in on this image just a little bit. And I'm going to start by duplicating this last action right there, for office printer, by dragging it and dropping it onto the page icon. And the reason I keep duplicating actions is that, I'm a big believer that, one you have a working action that might save a good purpose. You don't want to take a chance on wrecking it. If you're going to create a variation you're better off duplicating first. And I'm going to go ahead and rename this action. Convert for pre press and then press the Enter key, the Return key on the Mac to accept that new name.

And then I'll twirl it open. And I know that the first step is no good here. I don't want to duplicate the document, because that'll create no end of problems if we're batch processing a bunch of images at time. So I'll just go ahead and select that guy and Alt-click or Option-click on the Trash icon. And now I'll go ahead and press the Ctrl-key or the Cmd-key on the Mac and double-click on flattened image in order to apply that step. And now I'll click on that step to select it once again, because I want to add a step right after it in which we change the resolution of the image.

And to do that you click on a Step and then you click on the Record button down here at the bottom of the Actions Panel. Then go up to the Image Menu and choose the Image Size Cmd. Or you can just as easily press Ctrl+Alt+I or Cmd+Opt+I (Mac). And this time we don't want to change the number of pixels inside of the image because, you may recall. All these images have the same pixel dimensions. But I do want to change the resolution. So I'll turn off the Re-sample image check box, very important. And then you want to change that resolution value to 267 pixels per inch which is a very popular industry standard, then click OK.

In oder to create that step. And that's all I need. So I'll click the Stop button in order to stop recording and now if I twirl open image size, as you can see, just one item listed there. We're changing the resolution and nothing more. So it's very important that you save only what you're changing. Here inside the Action panel. Alright, now I want to play the next several steps here. So I'll click on Set background and I'll Shift+click on Delete Filter Mask Channel. And when you have multiple steps selected like this, you can click the Play button to play those steps and those steps only.

So notice those steps converted the image to a Smart object and applied Smart sharpen as a Smart filter but I did not add the curve's adjustment layer because I did not have the last two steps selected. Now, if I zoom in here, you can see that we've got some problems. We've got a lot of chromatic aberrations that we're not going to worry about. But we also have some over sharpening and this is a very noisy image, in fact pretty much all of them are. So we need to add a step to reduce the noise. So I'm going to do that right after the convert to Smart Object, because you want to reduce the noise before you sharpen the image.

So with that step selected I'll click on the Record button and then I'll go up to the Filter menu, choose Noise and then choose Reduce Noise right there. Then I'm going to change the strength value to 8 and set the preserve details value to 10, and then I'll enter a Reduced Color Noise value of 50%. I don't want to be sharpening the details because the next step does exactly that and much better than this dialog box does. And you want Remove JPG Artifact to be turned off. Now, inside this dialog box, you can go ahead and save your settings.

So that settings problem we encountered is specifically a smart sharpen thing. And I'm going to call this something like, prevalent noise, let's say. And then click OK. And where this dialog box is concerned, you have to make sure to choose that setting that you just saved unless you want to overwrite the previous one. And then click OK. And now notice, if I twirl open this step, it's saving all of the numerical values plus a lot that I didn't change at all. So I'll go ahead and twirl that guy closed and I'll click the Stop button once again.

Alright, now let's play back our action to see how reduced noise has affected the things. So I'll go up the File menu and choose Revert command. And then you want to click on Flatten Image and Shift click on Reduced Noise to play just those stamps. And then drop down to the Play button and click on it. And now we need to test down our smart sharpen settings by double-clicking on the words Smart Sharpen. And the image is still going to look way over sharpened. So I'm going to take the amount value down to 200%, which still creates an over Sharpening effect.

But bare in mind that we're going to fade this effect in the very next step. So I'll click OK in order to make that modification right there. Then presumably, you would go ahead and click and Shift click on these guys and play them. But I'm here to tell you, we already got a problem with this step right there. Notice what it's called. It says, set Filter effects one of current layer. So current layer's great but filter effect one is reduce noise. So we'd end up setting Reduce Noise to luminance, which would kill the fact that I want to get rid of color noise, and it would reduce it to 50% as well and it'd leave the Smart Sharpen effect completely in tact.

So what we have to do is delete this guy and re-record that step. So I'll Alt+click or Option+click on the Trash icon to get rid of it. Then I'll click on Smart Sharpen, click on Record And then double-click on the sliders for Smart Sharpen to bring up the Blending Options dialog box. And I'll change the mode once again to Luminosity and I'll reduce to opacity value to 50%. And then I'll click OK in order to apply that step. And you can see, now it says set Filter effects to of current layer, which is exactly what we want.

Now, you can press the Escape key or click on the Stop button to stop recording. Alright, so that's at least how you begin the process of modifying an action So it will suit a wide variety of images. In the next movie we'll modify the Curves Adjustment layer and I'll also show you how to introduce a Save As operation.
