Advice on images please
I'm sorry if this is in the wrong forum for this post, and to have to expose my abysmal ignorance about images.
The attached image is from a book published in 1894, taken from the Internet Archive. I'd very much like to use this and ten similar quality images as illustrations in an ebook I'm proof reading now. My questions in decreasing order of importance are: - Is the image fixable - can it be improved enough to make it usable? - How would you describe what is wrong with the image? What needs to be fixed? - What software would you recommend? - preferably free. I have PMView, Paint, Irfanview, and GIMP 2.8. But I am starting from scratch so far as doing more than sizing and cropping, which is part of my reason for asking what is wrong with the image. I haven't found anything in the Wiki; is there anywhere else I can get help from? |

I don't see actually a lot wrong there. It seems like a grayscale image (although heavy on the black) of a painting. Perhaps a small 'cartoon' filter used additionally.
Perhaps you can find a better image of the original painting? It looks a bit familiar. |

It looks like a bit like it has had a blur/despeckle filter applied, but it might simply be old printing technology.
As for advice, I'd fetch the "original", which in the Internet Archive means clicking on "All files", and then choosing one of the largest files, probably one with "jp2" or "raw" in its name. If the image can be improved, it will be from there. |

Thanks to you both.
You might have read the book, Toxaris, it's from Under the Red Robe, by Stanley J. Weyman. I don't think it's a stand alone painting. I got the images from the ePub version, Jelby, and never thought of looking in any other file. I'll go back and check. I'd still like to know how to fix images myself, though, and don't know where to start. |

I don't think there's much to be fixed as it is...

I don't know the book, but the painting style looks familiar. Then again, that may be because of my cultural heritage.

Since Jelby's post yesterday I went back to the Internet Archive. Although I couldn't find a 'Raw' set of files anywhere I did find another version, downloaded the ePub file, and unzipped it to get at the images it contained. Most of the images seem better, but I've attached another image which seems even worse. The scene is in an inn at night, and to my untutored eye looks awful. I know it doesn't look good, but don't know how to fix it. I've seen and happily used other images I got from Internet Archive ePub files for other MR ebooks, but they looked a lot better than these. |

hi Alex. I took a quick look at archive.org, they have quite a few editions of Under the Red Robe. From just a fast glance, it looks like *maybe* the images in the archive http://archive.org/details/underredrobe00weymiala *might* be the best quality you will get (though they still are not excellent, reproduction methods were not the best back then for paintings and photos).
To get the scanned pages -- on the "download" page for each archive, under the list of formats offered, is a link for "https". This will take you to the FTP page, and you will find a list of files. Look for the ones that end in jp2_.zip, or jpg_zip. The image zip files are quite large, and sometimes very slow to download (often 20 - 45 minutes!) Use the "read online" feature to view the book, and download the ones that look best to your eyes. Then the only thing you can do is open the zips and take a look at the actual scans and pick the best ones. Sometimes, it is better to use individual pages from several different archives (when available). The actual physical cleanup and re-sizing depends on the image editor you decide to use. As you know, I use PaintShop Pro, and not too many folks do. Lots of people use the GIMP for free, or Photoshop (pricey!). There are lots of freeware image editors out there, many very highly rated, such as PaintDotNet. In general, you usually need to either completely desaturate the image or convert it to grayscale. Then maybe adjust the contrast, then clean up scratches and spots, and downsize the image. Keep the image in a lossless format, such as bitmap or (photoshop) psd, until the very end, even though the file size will be very large. Jpeg is lossy, and you will lose quality every time you re-save the file. (I haven't forgotten, I'm still plugging away at Innocents, but not much free time these weeks) EDITED TO ADD -- PS --The image you posted is pretty bad, though I have worked with worse. The only fix for something like that is to literally restore it using clone brush and smudging, and dodge and burn (yep, like developing photos). Sometimes you can't tell if the flaws are due to dirt and damage, to scanning artifacts, or if the artist actually drew it that way, very frustrating. It takes a lot of patience and sometimes the end result just isn't worth the time and effort. The attached samples from a book I worked on once show a fair amount of improvement, I think, but I don't know if it was worth it. But at least now the man in the corner actually has a face.

Thanks, grannyGrumpy, that really is most helpful. I'm downloading the raw jpg file as I type.
I guess I have to grind away at GIMP until I understand it. |

What I do:
The raw/jp2 images are even larger and more detailed, but In my experience there wasn't anything to be gotten by using them instead. Also, they are often not yet aligned, so you'll have to rotate them a bit as well. When there are many images in a book, I use the Internet Archive thumbnail viewer, note down the page numbers of images, and make a shell loop to retrieve the relevant pages. This is left as an exercise for the reader Last edited by SBT; 07-03-2013 at 04:49 AM. Reason: Expanded with images ++ |

@Alex, there are many GIMP tutorials online, and maybe this link would be a good starting point: http://www.gimp.org/tutorials/ . (unfortunately, I never felt comfortable with the interface, so my knowledge is only incidental)
@SBT, I wanted to try your step-through, but the Internet Explorer v9, which I am locked into using, doesn't have the option to open an archive.org reader page in a new tab, the option is grayed out. It only allows Save Picture As, Email, Print, etc. What browser are you using? |

If you are utterly stuck with IE, you can right-click, and select 'Properties', that'll list the image link and more. |

arghhh. Pasting the link into the address bar gives me a "bad image stack path" error.
I will have to try this from the library, where I can use my own portable Opera. This problem might be due to some policy settings, or it might just be a Vista thing (have I mentioned how badly I hate Vista?) |
