A pretty common thing you need to do with images, especially if you've scanned them on a scanner or even just digital camera shots, is something called Spotting, where you want to zoom in on your image at a pretty decent zoom percentage and start panning around the document looking for imperfections like dust and spots and scratches and whatnot, and then you want to quickly retouch them out. But you want to make sure you cover every pixel to make sure you don't miss anything. So the best way to do that is just zoom up to an appropriate zoom level and then start panning around the document. The idea though is to do it one full screen at a time to make sure that you don't miss any pixels. So here's how I would do that. I would zoom in to a particular size, I'm going to start at 100% Command+1, Ctrl+1.
I'm going to go up one notch higher so Command+Plus or Ctrl+Plus and we want to start in the upper left hand corner. So if you look at your keyboard, somewhere on your keyboard you will have a Home and an End key as well as a Page Up and a Page Down key and those are actually very useful for a Spotting workflow. To begin I'm going to the Home key. That puts my upper left hand corner of my image in the upper left hand corner of my screen, and you can see I got a problem right away. My panels are over on top of the image. So I'm just going to press Tab to hide my panels. Before I do that, you'll see I have got my tools and I'm going to use already set the Healing Brush tool, in this case the Spot Healing Brush tool, and I can just press the letter J for that. So I have already got the tool I want. I'm going to hit Tab to hide my panels and now I'm starting the upper left hand corner and I can see a little imperfection that I want to get rid off right away. So I'm just going to go ahead and click on that with the Spot Healing Brush tool and it takes care of that.
Now if I just use my Hand tool, Hand pane, that's where I can get in the trouble, because I'm not going to be very precise and I might end up overlapping or missing a section of pixels. So I want to go one full screen down at a time. So I hit the Page Down key. That will move my image down one full screen. I don't see any imperfections there. So I hit Page Down one more time. Oop, there is another one, so I'll just hit that with the Spotting on the brush. Page Down one more time. I now see the bottom of my image and I have covered that vertical strip of those pixels. I now want to go over to the right one full screen and that's when you add the Command key or the Ctrl key on Windows to your Page Up and Page Down key. So if I do Command+Page Down. That moves me one full screen to the right. If I did Command+Page Up or Ctrl+Page Up, that would have moved me one full screen to the left.
So I've moved one screen over to the right. I don't see any imperfections. I hit the Page Up key. That section of the pixels looks good. One more time, and that looks great and so on. All the way up to the top. Okay now I want to move to the right again. So Command+Page Down, it moves one full screen to the right, Page Down, Page Down, Page Down. Oops, there's another one, I'll hit that up with the Spot Healing Brush, and finally Page Down. So again Home takes you up to the upper left corner of your screen. End does just the opposite. It puts the lower right hand corner of your image in the lower right and of your screen, and then Page Up and Page Down do exactly what they intend to do, what they are labeled to do, and then adding Command on the Mac or Ctrl on Windows to Page Up and Down moves on left and right.
Okay, so there you have it. When you're all done, Command+0 or Ctrl+0 to fit back to window and you've got a very fast, fluid, efficient way of doing spot removal.
