Oversharpened

I have uploaded a DVD cover on three different occasions and they were all deleted for being oversharpened. I also uploaded a few postcard scans and a poster for Animage, all of which were deleted for being oversharpened. I can't remember a scan of mine being deleted for this reason before and I am not even doing anything different then I have done with my other scans. What really bothers me is that my last deletion for the third upload of my DVD cover assumes that each one was the same exact scan when I rescanned each resubmission. See PM below:

Quote by SquirrelLuvsPnut,

The scan you have submitted ([url=http://gallery.minitokyo.net/view/690596][/url]) was removed for one or more of the following reasons:

- The image was too small. Only scans with a clear subject of 1,000,000 pixels or more are accepted.
- The scan contains excessive artifacts. This includes, but is not limited to: page folds, dust, or text on the image.
- The image was enlarged. The majority of anime images found on the internet are not sufficient quality to be submitted at Minitokyo, please do not attempt to enlarge these images for submission.

If you still find the scan is of decent quality however, you can always submit it at Minitokyo's sister site: Zerochan.


Sincerely,

Minitokyo Staff

Additional information provided by the moderator:
Oversharpened. Please scan this again, do not keep resubmitting the same image in the same bad quality, because it will be deleted every time.

Inquiries can be made in the Deletion Complaints forum.

If they all are indeed oversharpened then how can I fix this? I'm worried that my scans won't be accepted anymore.

Hi, I deleted your scans for oversharpening and quality reasons.
You submitted the same scan three times, despite being advised not to do so until it is better quality. The only differences between the three versions are like three pixels.

I don't know if you can see the scan(s) anymore, I'll take 690299 as an example: direct link to full-size scan
I'll take another scan to provide a visual example of what I mean:

Here is how your scan looks (right) compared to how it should look (left); it is too sharp, the brightness is hiked up too much, and the girl's face looks much, much too bright (like you ran the Dodge Tool over it - which I did, in this example).

I've noticed that all your scans are much too sharp. Either you are sharpening them yourself in an image editing program (in which case, tone it down) or your scanner is saving the images too sharp/bright. I don't know what model scanner you use, but most scanners come with software that allows you to adjust the quality (brightness, contrast, sharpness) of the image before saving the images. Look into your scanner's settings and tone down the sharpness and contrast a bit.

The image should look smooth - at most, the paper texture can be slightly visible. In the case of your Tokyo Ghoul scan, the sharpness made the paper texture much too visible. It would be the scanning equivalent of paper getting jammed while printing.

Your Owari no Seraph and Onepunch-Man scans were deleted for the same reasons (brightness is not an issue, but the too high sharpening leads to the images being full of white spots).

Okay, so how low should the contrast be? My contrast can go from -100 to a full 100. I did a few scans by messing around with the contrast on either side and the scans looked worse then before. Here's one scan done at around -40 contrast:

It only seemed to wreck the color as opposed to fix any of the visible lines even though I left the brightness alone.

Please try to be patient with me. I want to try to fix this if I can.

No worries, we have a lot of time on our hands and there's no rush to solve things. That's what this forum is for, after all :)

This is how your scan should look, with the correct contrast. You also need to deepen the level of Black and lower the Brightness; the contrast is enough, you don't need to lower it. For some reason, this scan came out too bright and too saturated (increasing the contrast also lead to the characters' skin looking unnaturally yellow).

The main problem with the scan you linked in your second post here are the lines. My old scanner made lines like these when it was on its last leg. You should not have those lines when scanning.

Here are some images with better contrast:
http://gallery.minitokyo.net/view/690667 (note: the white specks on this scan are due to the image being scanned at a high resolution and having been printed at a low resolution, NOT because of sharpening)
http://gallery.minitokyo.net/view/690482 (this could actually stand to be darker)
http://gallery.minitokyo.net/view/690435 (same)

And some with correct contrast:
http://gallery.minitokyo.net/view/690652
http://gallery.minitokyo.net/view/690581
http://gallery.minitokyo.net/view/690574
http://gallery.minitokyo.net/view/690521
http://gallery.minitokyo.net/view/690491 (higher contrast, but the skin is not overexposed and you can see details on it)

These are too bright and look washed-out:
http://gallery.minitokyo.net/view/690500
http://gallery.minitokyo.net/view/690501
http://gallery.minitokyo.net/view/690502
http://gallery.minitokyo.net/view/690442

This is how grayscale images should look. Truly grayscale. Your manga scans have a brown tint to them. We don't delete scans for that, I just took the opportunity to remark on that.

http://gallery.minitokyo.net/view/690597 is a bit bright, but much better than the Tokyo Ghoul scan. The contrast is good.

Basically: if you have dark parts in an image i.e. black, they are supposed to look black. The black parts in your Tokyo Ghoul scan look gray.

Kay quick test here. Both of these scans have had their brightness drastically lowered. Obviously they are both too dark, but does one look less sharpened then the other because one is scanned from my usual scanner and the other one was done with a family member's scanner.

http://oi64.tinypic.com/x3vonb.jpg

To me, they look just about the same except the lines look more detailed in the second scan. Whatever I do doesn't seem to shake those pesky lines though.

One thing I really don't understand is that I have done nothing different with the scans that have been deleted and the one that was accepted (that Prince of Strides scan). Is it because the colors are brighter and so it mutes the sharp lines?

It's got nothing to do with the bright spots, it's the dark ones you should pay attention to in this case. If you'll look in the dark spots of the Prince of Strides scan (e.g. Takeru's hair), you'll notice that the image isn't as sharp as the Tokyo Ghoul scan.

To me the two Tokyo Ghoul scans look like they were done with the same scanner, except f1d1nb looks more blurred and greenish than x3vonb.
The brightness looks lowered too, which is good. Like in the examples I gave above, making images too bright leads to loss of detail, and you don't want that. I would say the brightness in x3vonb is good enough, maybe a tiny bit higher. But x3vonb is definitely the better version of the two.

Now the sharpening doesn't look like it's a result of the texture of the paper, and it doesn't look like the images were scanned at a higher DPI than the one they were printed at, either. Which leads me to believe that the sharpening is a result of the scanner's settings. Which manufacturer is your scanner from?

It's an HP deskjet dual printer and scanner. I don't know, I guess my scanning day's are over now.

I have an HP scanner too. When you scan an image and the image preview window comes up, you should have a few tabs (one of which controls the brightness and stuff). I don't know your model so just poke around the options until you get what you're looking for.

Ah, I'm not positive but does F4400 mean anything? I found it while looking under properties deskjet properties.

I am not sure, as I don't know how your scanner is set up. What's even more curious is how some of your scans (like your Prince of Stride one) look fine, but others turn out too sharp or too bright (or with scan lines).

I have no idea what the issue is. I have been scanning with the same scanner for years and only now am I having trouble with oversharpness. I'm assuming that the only thing that might help even a little bit would be to buy a new scanner, but I don't know if I have the money for it right now.

I have a couple of scans that I have been too afraid to try to upload, so could you tell me if these suffer from the same problem or not? I think a lot of the white spots in the first scan is mostly due to the texture of the paper. I see lines in the second one, but I don't know it it's considered too much or not.

Both of them look fine to me. Your scanner must've really hated the Tokyo Ghoul image, lol. In which case buying a new scanner for one image that turned out wrong...really isn't warranted. I replaced my old scanner when it started producing lines and the sheet that moved the scan head kept twisting. Supposedly cleaning the scanner will get rid of those lines, the forum threads I've seen on this topic say the lines are due to dust. But disassembling the scanner is a risky business on its own.

Are the two scans at the resolution you're planning to upload them?

P.S. the Vocaloid image is too small to see any white bits. But they are generally caused by the paper texture (image printed at low DPI, on bad quality paper), excessive sharpening when editing, or dust that can get between the image and the scanner.

Both of those scans are scaled way down. The image sharing site does that with images exceeding a certain size. I'll just give it a shot with these and maybe some from an anime magazine. Sure they'll probably just get deleted anyway though.

Well, if you ever need to upload images at their original size, http://imgur.com doesn't resize images.

Okay, I tried with a few more scans and two out of three got deleted again. Funny how it was another Prince of Stride scan that was deemed good enough again. I really appreciate your help, but I think I'm done scanning now. It's not fun anymore if you're not wanted. Just a quick question thoughh. Are my past scans just as bad? The one's I've done for years? If so shouldn't it all get deleted?

The other two had scan lines, which are very visible - probably because they were darker. The Prince of Stride one is currently under discussion, since the dark parts also have those lines. Unfortunately, it appears your scanner doesn't scan things properly; I can sympathize with spending money and wanting to share images, but if you've rescanned things and gone through settings and it's still not possible, your hardware is simply working against you.

It's nothing against you personally, please don't take it like that. It's a question of maintaining the quality of the images submitted to the gallery, and it would be unfair to keep scans which are clearly bad quality, when we normally delete scans for far lesser obvious defects. Hell, I've had a lot of scans deleted too.

As for your previous scans: I can't tell you anything right now, since we're discussing the more recent ones.

I reported the last scan so it will get deleted faster. You guy's shouldn't even bother discussing it. If it's bad, then it's bad.
