Tips and trix for Editing Doujinshis.

Okay first of there is soo many bad scanners out there and I want to guide them
to a tiny bit better scans, first of really it's more the 'editers' work to fix
the scans up, as the quality of the scanner itself doesn't matter THAT much. Any
50-100$ scanner works more or less as good. And pretty much it, scan at decent
DPI and gray scale for black and white doujinshis/mangas.

This is how a finished scan could look like.
As you can see, a lot of ink spots who got there due bad printing, and lots of
shadows from the paper itself you don't want here... You just think MEH this
will take hours to edit but no it won't, it goes pretty fast Razz

Step_001.jpg
First of start with cutting out the page itself, pretty easy in photoshop, just
use the Rectangular Marquee Tool and select select the page itself and copy past
it in a new document, I recommend having a 'WHITE' background for way faster
cleaning pages up, more about that later.

Step_002.jpg
Now I think you think, WOW what just happened here? the bad shadows is gone
and it looks almost perfect except the ink dots here and there. Well
this step is quite easy, but may take a bit 'trial' and error, it all really
depence on the scan, the paper and so on.
First of what we did here is using Levels, basically telling where 'white' start
and where black is black, and hence removing a lot of 'gray' as you upping the
white level.
In any event some pretty decent 'levels' you can usually play around with.
0 0,76 228 for pictures with really bad shadows, some times this is not enough
but more about that later, For color pictures you may want to use level's to
and some doujinshis who's not that messy but need a tiny clean change 228 to
a higher value, example 240. You can expirment with any value between 228 and
240 for the matter, but I don't recommend going higher or lower, Instead apply
the level more then once.
On this picture I've used 0 0,76 228.

Step_003.jpg
This is an even easier step, just to clear up the last shadows ( usually at the
corners of each page) this page however does not have any, but don't bother try
to fix it with levels as you will most likely destroy all shadows the art had.
Here just use use ANY select box and mark whatever you want gone and delete it
This is the reason why you wanted to have white background Razz. to speed this
process up.
You can also use Clone stamp and just normal spray over with a complete white
color.

Also here we are now done with this page, just rinse and repeat with every page.
This page took me about ~2 min to fix. Some pages requires barely any work and
some other requires a lot more, you get used to it Smile

Misc:

Q: Why bother clean a picture up?
A: Because it will look closer to the original it once was, this way described
above will clean the picture up and make it look like it was an original ink
painting. Plus the quality of the pictures become so much greater, and even
the file size decrease quite a tad bit saving it.

Q: How much file size get saved?
A: Well depence on how bad scan it is, on this example.
Step_001.jpg = 433,3 KB 002 = 294 KB so a total of 139 KB saved.

Q: Is my way the only way?
A: No it's not the only way, it's my way, there may be other ways who work as
good but this is the way I prefer.

Q: Why not use Auto Levels?
A: Oh hell no, do you want to destroy the picture even more? NEVER EVER use auto levels, it really got no purpose for this at all!.

Got any other questions or tips go ahead and fill it out. Razz sorry the pic I made for this was not a loli picture Razz
