here is my step:
| Code: |
first used "Scanner" to scan "Gray" dpi.300 image to "TIFF format.
open [file] photoshop
I can see title is [filename.tif] [Gray]
Image (I) >
...Adjust (A) >
.....Auto contrast (Alt+Shirt+Ctrl+L)
and:
Image (I) >
...Mode (M) >
.....Bitmap (B) >
set output(o) 300
method
used: 50% contrast
_click OK
and
Save As , done!
|
My problem is:
what mean "50% contrast" ?
is fixed, no changed that "50%" or
can simple set 10%,20%...80%,90% contrast" ?
please!
