To make the resolution to change with DPI, you need to check the "keep print size" option.b923242 said:
Last week is my first time scan my collection. Before I upload it I know I have to edit and compress it first. I follow all the steps in this post.
https://yande.re/forum/show/10739
But in the progress I still got a few problems.
- when I using XnView to resize the image. I resize it to 300dpi and the original was 600 but the width and height remain unchanged. So after the resize I get a image 5100*7014 with 300 dpi. Should I also make it 2480*3508 to match the format of 300dpi A4 size?
BUT do not do that! The point of using XnView instead of Photoshop to resize image is that you can choose better (Lanczos) algorithm, however if you resize with "set DPI" function, there is no way to choose.. so it counters our purpose. So, besides "set DPI" (and don not check "keep print size", add another "Resize" transformation to resize your image. Be sure to use Lanczos resampling.
And about your scan, it looks ok for me. Can't really judge if not seeing the raw though.
So I do need to resize it back to the 300dpi resolution?fireattack said:

And I uploaded my raw file here:

I am not sure what you mean, when I said "resolution" I was talking about pixel x pixel. DPI is irrelevant.b923242 said:

And the raw is pretty bad. Mostly due to cheap scanner (no offense). The size doesn't help, too: did you resize it already? Even a single page of A4 @ 300 DPI should be larger than this, not to mention B2 (I assume you scan multiple times and stitch)
I did resize it follow these data. (So it not necessary to resize it after changed the DPI?)fireattack said:

The bmp file is 5100*7014. And the image is not a A4 size so after i cut it out from the background it became 1589*2244. (About a A5 size)
About the B2 tapestry I scanned. It really hard to scan since it not a paper and every time I put it into the scanner the sharp will change it little bit. Now I don't even know how to make it back together.....
If the original size is about A5, the resolution is fine. The whole point is to keep your scan at around 300dpi (and respective resolution) so a good balance between file size, quality and the difficulty of processing. If the quality is higher the dpi could be higher too.b923242 said:

One more thing that I want to know. I know people scan dakimakura they can only scan a part of it every time since it so long. But for tapestry i rare see people use this method. Do they have a big scanner that big enough to put it in or simply because it not a scan?
No.. they just scan by pieces and stitch. Nothing special..b923242 said:

Scan progressing problem

- Just simply when to ask are there any good way to remove the noise of the scan? Since I feel pretty unsatisfied with my job here:
https://yande.re/post/show/340406
the filter I use are NeatImage, Gaussian blur and those Photoshop noise remove filters. After apply the filter i just use Spot Healmg Brush than adjust the color.
Any anime image edit master can share their experience =) ?
