Lazy Scanlator Guide: extra short version

Crop:

If you want to release LQ then use "File>Automate>Crop and Straighten Photos".
If you want better quality then crop manually. pic
If you need to crop a problematic double page then read this: http://www.kickthekitty.ucoz.com/blog/lazy_scanlator_guide_cropping_and_editing_a_douple_page_draft_2/2010-04-19-9


Levels:
First make sure your pc monitor isn't set for extra brightness or contrast.
Here's the way I do leveling:
image before leveling
 pic1 First I view image at it's full size. (CTRL+1) And start Levels tool. (CTRL+L)
 pic2 Then I move black arrow all the way to right to better see gray dirt in image.
 pic3 Move white arrow to left to remove dirt.
 pic4 Now move black arrow back to left.
 pic5 And move gray arrow to left next to black arrow
 pic6 Move black arrow to right to remove dirt.
 pic7 Then take full view (CTRL+0)
 pic8 By moving gray arrow to right you can darken image.
 pic9 And by moving it to left image lightens.

Don't bother to remove all the dirt. As some of it is just very near black or near white tones which has  no real effect to what image looks.


Resize:
Photoshop can not resize properly if mode (Image>Mode) is set as "indexed color". (and PNG's are indexed color.) Set mode as something else, like RGB color, if it's set such.

Change image size by changing value of height or width or by setting a percent value.

Denoise:

Do not use Photoshop's denoise. Use plug-in. I recommend Topaz vivacity denoise and Topaz Labs denoise.
If your image is LQ or resizing left interpolation artifacts then denoise will improve it significally.


Save:
-Save color images as jpg. (ProJPEG plug-in recommended)
-Save grayscale images as PNG-8.  File>Save for Web & Devices  Use settings:"PNG-8" "adaptive" "no dither" "interlace=off"  (PIC)
Number of colors depends what is being saved. Keep increasing the number until preview looks as good as original image.
As a thumb rule:
 For >2000px height between 8-16 colors. Pic
 For <2000px between 16-32 colors. Pic
 For image with smooth tones atleast 128 colors.
