Denoise Filters

Denoise 3

> Thanh Suppress noise - Đây là thông số chính cần thay đổi. Giúp xóa noise nhưng cũng làm nhòe ảnh. Thường kéo khoảng 0.8 [0.70-1.00]

>Thanh Clean - Làm phẳng ảnh, lan đều màu. Giống như một surface blur (làm mờ bề mặt), đặc biệt (kiểu như khi ta chọn filter > blur > surface blur). Mình thích để tương đối cao 0.70 [0.5-0.7]

> Thanh Recover Details - Tái tạo lại hình ảnh bị denoise, giảm hiệu quả của suppress denoise

> Thanh Reduce blur (giảm độ mờ) - Khá quan trọng, làm ảnh đỡ bị mờ do denoise. Làm các cạnh sắc nét hơn nhưng giúp cho tones/caro đồng đều hơn/ có thứ tự hơn và sau đó dùng topaz denoise 5 cũng sẽ dễ hơn. Mình thích để khoảng 0.4 [0.20-0.40]

>Các thanh còn lại để 0

Preview trong topaz denoise 3 là 200%  sẽ dễ nhìn tác dụng của topaz hơn như kiểu dáng screentones sau khi topaz hay vùng đen và trắng bị làm phẳng/bị ảnh hưởng như thế nào.

_____
Denoise 5

Dùng cái này là để làm screentones/caro tiếp tục được đồng đều hơn/ có thứ tự hơn, ngoài ra nó sẽ làm mờ vùng đen và trắng đã được làm phẳng sau khi topaz denoise 3

Chỉ thay đổi các thanh này:

>Overall Strength - Làm mờ ảnh. Nếu chỉ muốn tác động một chút thì để là  0.20-0.35.

>Reduce blur - Làm các nét vẽ màu đen không bị mờ hay nhòe quá. Để khoảng  0.10-0.13.

Lí do không dùng các thanh khác là do các thanh còn lại chỉ thay đổi độ tương phản hoặc làm đậm (sharpen), mấy cái filter có sẵn của PTS còn làm tốt hơn.

Ngoài ra có thể denoise 5  để làm đều screentones/caro và làm mờ bụi sau khi level. Sau khi level ở 8000 px chiều dài thì resize về 3000 px sau đó thì dùng denoise 5:

>Overall Strength - 0.80-1.00

>Reduce blur - 0.00-0.13

Detail Recovery

Denoise filters at their core are fancy blurs. They have a habit of blurring out 'textured' areas, black/white line details on patterned areas, or making white details on black areas turn to mush.
Once you level these details will be lost/destroyed. It's our job as cleaners to have our screentones looking top notch while keeping as much of the original detail as possible.
It's not possible to do this without recovering details from the raw image.

These techniques can be applied at almost any step in the cleaning process, so if you see something's missing you can always grab it from the raw. Keep in mind though that doing it at 3000px will yield the best results.

Line Detail Recovery
 (click to show/hide)
Line Detail Recovery is normally done before resizing to 8000px for leveling but after denoising. We use a sharpened copy of the raw layer with the layer-mode set to darken for black lines, and a separate identical layer set to lighten or screen for the white details.

Duplicate the raw layer, sharpen it a fair bit so the details stand out (unsharpen mask 60-80%, 0.9).
Create a mask and then use either the line tool or the brush tool to 'mask out' these details from the layer using a black coloured brush/line tool on the mask. Once you have masked out the
details you want to keep, you invert the mask, level slightly (usually only for blacks), then change the layer mode.
Merge these with the cleaning layer, you might want to duplicate the layers and keep copies during cleaning in case you need to touch anything up after leveling/the potential 3rd denoising at 3000px.

Raw Texture Recovery
 (click to show/hide)
Another type of recover is Raw-texture/pattern recovery.
This form of recovery can be done at almost any time during cleaning as you just have to go to the raw layer and grab the selection.
Personally I prefer doing the selection at 3000px either before resizing/leveling or after resizing/leveling. There are some cases where I have to do it at final size as well if topaz messes up something I didn't think it would, or if I just missed it. Doing this at 3000px does make it look better since you're leveling a pattern at close to the original size rather than a smaller, down-scaled version. Since topaz ends up messing up these texture-based patterns you need to go extract them from the raw, using either the pen tool or polygonal lasso (I prefer pen/paths tool) select the area then layer via copy onto a new layer. From there sharpen it then level.

Topaz Clean 3

Topaz clean filtering serves to smooth out pattern gradients, and helps to make white-dirt on black areas fainter (easier to burn)
Settings breakdown.

 (click to show/hide)


Threshold controls the balance between smoothing gradients and blurring out line-details.
Sharpness controls the edge and screen tone sharpness.
texture controls how prominent the screentones are.


Though topaz clean is a great filter, it does have its flaws.
 (click to show/hide)
Topaz Dust
Topaz clean is notorious for creating a fine layer of dust on the whites of the image. Dust Example
After the filter has completed, level the blacks and whites by at least 5 each to make sure this dust is gone.

Topaz Clean Rings
If you attempt to use the filter on a page as is, it has a high possibility of creating a 'Topaz Clean Ring.'
This is when topaz clean creates a jagged/overly sharp line, several pixels thick, around the edge of your page's patterned edges. Here's an exaggerated example: https://db.tt/duefGz65
To avoid this you need to expand canvas by 100px each side - relative, then if there's blank space, fill it with white. (I find creating a white fill layer behind the clean layer, then merging it down works best). After your tc3 filtering you contract the canvas and continue with the page. Here is an action that will expand/fill the canvas and contract it by the same amount: Download

Sharpening

There are two reliable ways to sharpen. Unsharpen Mask, and the High pass filter Overlay method.
 (click to show/hide)

Adding on to what the above image said, when using the high pass filter try to keep the radius value low (I almost never have to go above 1.0).
Changing the high pass layer's mode can help with increasing contrast, I like to have it set on overlay for the most part.
Once you've gotten your ideal sharpen settings using the high pass layer, you must merge it with the clean layer before continuing to edit the page.

When using the Unsharpen mask filter I like to keep my settings anywhere from 0.36%/0.9radius - 0.60%/0.9radius.

Dirt removal

Sometimes denoising a page won't remove all the dirt from the image, rather than opting for increasing the denoise str values and blurring the page more you can selectively fix the crummy areas.
 (click to show/hide)
To remove additional dirt after denoising (before leveling) use the quickmask tool (default shortcut is Q) brush over the areas you want to remove dirt from with black (patterns only) Press Q again to go from the mask to a selection, invert your selection so only the areas you want are selected. Sharpen more, denoise 5 at max str, .13 reduce blur.

You can also attempt to use the spot healing brush; Mode: replace; Type: Content-Aware at 8000px, brush size has to be around the same size as a set of 4 tone-dots at 8000px or a bit larger, you will be clicking once over the dirt area to ideally get rid of it. This might need a bit of undo/re-clicks for the content aware aspect to not mess up. Try not to brush over large areas with this as content aware algorithm messes up a lot.

Taking advantage of the content aware fill method can help if you don't want to play around with the spot healing brush, make your selection then 'edit > fill'

Topaz clean - some of my crazy stupid thoughts about it

Topaz clean - some of my crazy stupid thoughts about it
1. Why do we need to use topaz clean?
2. Recover details  right before and after topaz clean
3. How to topaz hayate tones - 1300 px


if publishers print manga (which is original black and white(?) in yellow paper), it is fine for eyes to read more.

i always wonder the way publishers make digital manga. maybe something wrong if they only scan the page author draw (with tones) and resize, it is something bad... black and white color and wrong final size (all is 1600 px). it looks inchy for me.

the page author draw >> scan >> print >> physical
the page author draw >> scan >> resize 1600 px >> digital

clean manga is to make page clearly to read. i think it is similar to make manga become digital. (though we used sharp...)

after..... then leveling and resizing page to its final size. the clean page are black and white.
if cleaned page is black and white, it is fine to see 1 page but i think it is harmful to eyes if we see many pages like that.

it is boring if the page only is black and white. let screw it by using topaz clean.

why do we need to use topaz clean? to have grey color (and to make gradient smoother(?))

Recover details  right before and after topaz clean
there are rather many cleaners already knew about this or even have better ways to recover and newbie can learn it himself by time too so i do it for someone don't know, it is not that i will lose something.

i'll take a page to do sample. it is manga Hanebado. (its final size is 1300 px high though i thought its size is 1400 px but then i realized that i was wrong )

after doing previous processs like unsharp, denoise, blur,... then the next step is level and resize to 3000 px high
duplicate Layer 1 (alt + j) and use topaz denoise (adjust strength to 1 or what you think it is enough. topaz denoise at size 3000 px high to have tone arranged better) with Layer 1 copy. then resize to final size (1300 px) (for newbie remember that resolution is 72 px/inch)


_______________________________ with Layer 1 copy
after topaz clean, image> canvas size... and fill white in blank erea, then topaz clean and canvas again to crop what was expanded by canvas
__
click here

image >> canvans size and type the number 200 or 100 ... ( >= 16 px) (relative is ticked)

then click here

then fill blank area with white (the area which was expaned)


click here again

then topaz clean (remember image > mode RBG color before using topaz)
the setting is
strength is 2 or 4. threshold is 0.45 - 0.99 or higher
sharpess is 1

texture is 0.6-0.9. always < 1 (texture 1 for redrawer)
usually accent,sharpness and boost need to be 1 and the other settings is variant and not constant.
__
btw is is fun to know that others canvas, make new layer and fill white and move layer clean above then merger layer. it is better than what i've said.
__
after topaz clean, the page will have some dust
level a bit again


then image > canvas size... what was expanded
__________
Why you have to canvas before using topaz clean?
topaz clean doesn't have effect on area in the corner (16 px?) so using canvas to avoid it.
_______
here is result

it looks good but if you compare to raw you'll see detail was lost (open in new tab to compare)

there are 2 kind of losing detail in this (gradient is not good too but i won't say about gradient)

don't know call "1" is what but "2" is called black line
___
now we will recover 1
there are 2 layer name Layer 1 and Layer 1 copy (which was denoise-ed at 3000 px high)
Layer 1 has more details.
use mask (layer mask) to recover details for Layer 1 copy. google it to know a bit about layer mask then practice.




after recover we have this


now canvas, fill white and topaz clean. compare to the previous this is better.

__
now we'll fix 2 :black lines which were lost
it is fun that we won't recover black line as we did to recover 1. because topaz clean with wide threshold, black lines will lost again.

duplicate Layer 1 and fill white and topaz clean it with short threshold (not canvas because it was already canvas-ed. we canvas-ed when we did Layer 1 copy)


you see it has better black lines. use mask to recover black lines (which was from topaz clean-ed layer which was duplicated from Layer 1) for layer which was recovered 1 and topaz clean-ed

move layer was recovered black lines above layer which was recovered 1 and topaz clean-ed. select layer mode darken then merge.
although it was recovered black lines, why does it still need "darken" above not-recover-black-line layer. it is bacause the different contrast between 2 layer we used to recover. you'll understand when you practice more.


you also can recover white dust


here is the final result after recover 1 and 2 (for newbie, remember after topaz clean, level a bit to remove dust). compare to the result which is not recover. it is not bad, right :D. btw there are still some errors. i didn't fix highlight in panel 2 to save time and the recover is something wrong too, i think i need to recover at process denoise raws to improve result. but with this quality. it is ok. i don't need more. if i want more, it will take more time too.

How to topaz hayate tones
Knight told me the proper size for hayate is 1000 px high. it is good for topaz clean but it is small to read and causes trouble to typeset too.

hayate has big screentones in 1300 px high. topaz clean with normal setting won't have effect at all (but 1000 px is perfect)

so here is the best past. i can topaz clean it. i've found out yesterday (it is June 13).
before topaz clean
topaz clean with normal setting
topaz with sharpness 0.3 and level again 5 250 2 times
topaz clean has effect on hayate tones at size 1300 px with sharpness < 1. but it causes blur.
hayate chap 496 i cleaned the first part with that setting. although it is blur a bit, after seeing it again and again many times, it is actually harmful to my eyes.

now let try this



topaz clean like this 3 times and level 5 250 2 times. here is result. (remember with other manga, topaz clean 1 time with texture < 1 is enough. topaz clean > 1 time (with texture < 1) will look very bad and level 2 250 1 time is enough)
it doesn't blur anymore.
see more the effect of topaz clean on hayate tones

http://puu.sh/innpU/c980d1690d.png
http://puu.sh/inmO4/43230bf1b4.png

i will explain the setting
sharpness - 0.3 : topaz clean is enable to have effect with this but it causes blur
texture - 0.9: reduce effect of topaz clean >> reduce blur, and need < 1 to have grey color
size - 6: reduce effect of topaz clean >> reduce blur

with this, sharp is remaining after topaz clean. so i topaz clean 3 times to make black and white caro become grey. althought it is only a bit, it has effect.

if we zoom to see caro
before topaz clean

after topaz clean 3 times




i created another way to reduce blur a long time ago .it worked but it is not enough.. with this setting of topaz clean, now hayate tones can be topaz clean-ed without blurring.
________
because of some problems, i gave up finding the proper setting to topaz clean hayate tones at 1300 px. when i cleaned shinobi no ban, this manga has large screentones too, i found the way to do it and try the similar to hayate and bad luck for me that it worked for hayate.
after years finding the way to topaz clean hayate, i am too tired and finally can rest now. if you are free, let try and finish it you guys.

thanks for reading this point of view shit.
the right to decide belongs to you.
the fact that i learned cleaning from seeing what others clean manga as reference and built my own standard. there is no real standards for cleaning manga so feel free to do what you want.
 everyone has their own ways after all. if you don't want to topaz clean it, let don't. don't be so seriously as me.

10/6
update setting for hayate
yeah, size 6 will cause trouble



the last word...
it will be very easy, if we don't use topaz clean for hayate tones.
the way of cleaning decides if hayate tones will look good or bad after cleaning. i think it is topaz denoise which decides it. not topaz clean.
topaz clean in hayate tones doesn't help make tones better like almost other tones.

so why i have to use topaz clean?
1. i think although normal setting won't work, we still could topaz clean on it. it will be wrong if we don't try or give up too early.
2. if we can use topaz clean for other tones so why can't we use for hayate tones? if it can't, prove that it can't. don't say "it can't because i can't". if you can't prove it then...
3. so how can we use it to make tones better.
my purpose is one of them
-reduce sharpess of tones or
-make tones worse if all is bad orderly then in other words, consider that it mean all is good if you understand otherway

after try hard, my result is not what i want. it is both blur a bit and weird tones.
(sharpness of pattern is reduced >> it is only better a bit compare to not use topaz clean.
sharpness of black line is reduced too >> it is blur, i don't like it. tried to reduce blur)

once again i reached my limit. although it is not good, i still use it. it don't make i am unique but it is what i think and i do.
i topaz cleaned hayate tones like that. welp, i want to stop.

sorry for my bad english.

Change log:
8/12 - strength 1, threshold 0.45
8/14 - boost 1.1
9/1 - topaz clean 2 layers
9/5 - topaz clean 2 layers
9/16 - change level, 13 250 >> 35 1.3 250 ; 7 250 >> 5 250
10/6 - used brightness/contrast. never thought i have to use it. it is bad. use 2 other layers then darken to fix what boost size 6 caused.

(i added contrast to fix blur. it means it will be different a bit what i did in chap 1B of this manga)

btw Haru no Houtai Shoujo. this manga used same tones too in tank from vol 2 or 3 i didn't remember

http://puu.sh/kxZ8a/53983b6454.png (koe no katachi)
the tones in hairs i used topaz clean too
there are some similiar tones to hayate tones (normal setting doesn't have effect :v)
