i thought it would be nice to devise a step by step instruction on creating high
resolution, raw scans that can be used to create glorious wallpapers.
as a background reference on "resolutions" i have scanned an article
by the imaging wizards at Photoshop Creative, that i have found most
informative: 123456
to scan one needs access to:
electricity
a computer
digital imaging software [PS or PSP]
a scanner [be sure to clean the glass]
an art-book [make sure book is clean not dusty, bloody, muddy etc]
i will be using Photoshop software.
before scanning: make sure to set up PS or PSP to directly IMPORT
scans. never use the scanning software to edit/scan provided with the scanner,
since PS is so much better at editing large scans and the image will be directly
imported into Photoshop.
now we can begin:
1) Open up Photoshop. We are ready to start scanning. go to FILE - IMPORT - THEN
SELECT YOUR SCANNER. I choose Epson Perfection 2580.
2) Always scan at the highest resolution you can. Never scan lower than 300
resolution. In this case I am scanning at 600 ppi. Hit PREVIEW and then
SCAN.
3) After scanning your images- hit CLOSE. You are now back in Photoshop. Hit C
to crop. Select the area you want to keep and then RIGHT CLICK and choose CROP.
Hit ENTER.
4) Next is resizing the image. Hit [CTRL-ALT-I]. Make sure all the boxes are
checked and the sampling function is set to BICUBIC SHARPENER or BICUBIC in PS7
or earlier.
5) Change the WIDTH to 2000. all other values remain fixed. i.e. don't change
them. if you want the width to be 2500 or 3000 etc then substitute that value.
the key is to only re-size 1 time. Hit OK.
7) Select the IMAGE QUALITY. In this example I used "8" since the
total file size was approximately 1.6 mb. Ideally the file size should be as
close to MT's 2mb limit as possible.
Great!
I usually scan with the Scanner Wizard And then I open the image in Photoshop- I never knew about the whole bicubic
thing, so I guess I'll do that for sure next time- nifty
what's the difference between the different types of resizing settings? (like
bicubic, pixel resize, etc.)
and also, I find that when I scan something glossy, like say magazines, it turns
out weird, 'cause there's subtle reflections or something....
and just a note to the PSP users: instead of Save or Save As, use "Export
-> JPEG Optimizer", and turn down the compression value until the file
size is close to 2mb as possible. Esp if you have lots of reds in the scan,
using straight Save or Save As will pixelate the reds horribly

scanning directly in PS will not only allow the retention of more pixel data but
will be easier on your pc's resources as well.

Re-sampling involves changing resolution. You
can either add pixels [up-sampling] or reduce pixels [down-sampling] through a
process called interpolation. Interpolation adds pixels to the colour value of
the surronding pixels. source: Photoshop Creative- see article in
OP.
Photoshop CS and above have 5 re-sampling image settings.
Nearest neighbour: Nearest neighbor
interpolation is the simplest method and basically makes the pixels
bigger.
Bilinear: Bilinear Interpolation
determines the value of a new pixel based on a weighted average of the 4 pixels
in the nearest 2 x -2 neighborhood of the pixel in the original image.
Bicubic*: Bicubic interpolation is more
sophisticated and produces smoother edges than bilinear interpolation.
Bicubic Smoother: Used to up-sample an
image. I do not recommend up-sampling scans/images. Mt does not accept scans
that have been up-sampled- that is has additional pixels added giving the
"appearance" of a larger scan.
Bicubic Sharper*: Used to down-sample an
image. Retains detail and sharpens even when removing pixels. [Photoshop
Creative]This is the recommended setting for Photoshop CS and above.

my first imaging program was Paint Shop Pro 9 and it is an excellent program. As
noted in my PS step by step, PSP can be used to import scans, crop, resize and
save.
the step for saving is, as Lady MapleRose pointed out: different in PSP than PS
and actually has an advantage; since you can see the exact file size and the
pixels compared [original/new size] next to each other.
to illustrate i pulled up a Hiroki Mafuyu scan that is
over 16mb. I will be saving the scan in PSP. this falls under Step 6.
6) Now SAVE the image. go to the main menu and
select FILE > EXPORT > JPEG OPTIMIZER. Change the value of the SET
COMPRESSION VALUE. In this case i set the value to "11", which gives
me a file size of around 1.8mb. Take a second to view the pixels of the final
size 1.8mb file compared to the original size of 16mb. Note: for best results
make sure the CHROMA SUB-SAMPLING is set to (NONE). Hit OK and choose a file
name.
