Removing moire effects.
Well, I don't exactly know how moire came to be. It is those lines in the tone of the manga that gets too prominent when you resize a page. Sometimes this is tolerable, but there are times that it looks real bad.
One of the practice page for Cleaner Test illustrates what a moire is.practice page
Before anything else, the following procedures must be done with the original raw scan and NOT the resized one.
1) Resize it to 90%.
2) Resize it to 80%.
3) Resize it to 75%.
4) Finally, resize it to 1120 height.
If you follow these procedures, you'll notice that it considerably diminishes the moire, and it looks smoother.Removing dust
Dust are those specks of grey all throughout the page. You're lucky if you get a really good raw, however, not all the time is this possible. A good way to remove dust is to do the following:
1) Make a new layer.
2) Fill it with a solid white color.
3) Set the mode to difference.
It will make all the dust in your page appear. Do take note not to use this in levelling because you'll tend to over level the page.Healing Brush
This is one tool of PS that is overlooked by many editors. Cloning can do a good job, if you're trying to clone out a detailed section of the manga, however, using Healing Brush is better for copying out tones. Because it blends seamlessly into the image making it look smoother. Do take care to change the mode to Replace for the first part and then switch to Normal to smooth it out.Levelling
There are two ways of levelling. First is to level before resizing, and second is to resize before levelling. For some pages, this makes the difference in the world. Exaggeration, yes, but it does make a difference and you'll notice it once you go hardcore. Resizing before levelling will squeeze the page texture making it look smoother and with less dust. But there are times when the first method looks better. Just try to experiment.
1) Select the WHITE POINT eye dropper and click on all the little grey dots until they're gone (don't grab from the page gutter or you'll over level the page!)
2) Select the BLACK POINT eye dropper and click on a solid black area. Most of the grey dots will go away in one click. You'll probably have to click on the almost black dots one more time.
Drag the black and white arrows to where it starts to curve inside. Adjust the midtone if necessary. I can't really explain this. People who would like to learn this, I suggest seeing Forever-More's editing tutorial. The eyedropper method works for me. Very rarely do I have to adjust the midtones afterwards because they're too dark.
Some groups digress from adjusting the midtones, but you can do this if you want. Putting in a higher number than 1 will make the grey colors looks brighter. There are times that this looks nice.Action
Programming in Actions will save you a lot of time. Instead of saving, levelling, putting in the usual things over and over, you can make an Action to do all this work for you. Well, I won't elaborate on this. There are a lot of tutorials teaching this.Cloning Dots Screentone
When you press ALT, a crosshair appears. Center this crosshair in the middle of a dot. Make sure it is in dead center of the dot. Now go find a dot near the part you want to clone it in, and press alt then center the crosshair on that dot. DON'T CLICK while holding alt, because will just make another reference point. If you hit the right spot, you can start cloning. If you don't, there's always Ctrl-Z.
And that's it. Hope you enjoy it. The tutorials here came from different tutorials and my own experience.
