Rawhide 15

Won Rawhide Kid 4 tonight for $15 plus shipping.

Rawhide 15 is in the repository.

I wasn't very good at math in school, but if there are 11 people involved in this group and some of the files have been downloaded 14 times, I'd say at minimum we have 4 new guests! Don't be shy, outsiders! Feel free to pop into the comments and say hi.

I'll probably scan Two Gun Kid and Tex Taylor this week, but I'm going to need someone to edit. My raws are big and sloppy, so download the test file I put up and see if you're up for the task and let me know.

Also, this 4shared place is picky about filenames. I updated the scan_project and scan_project_checklist files, but even though I deleted the originals I can't rename the new files, so they'll be dated from now on.

your raws would be easy to edit, for me. I have edited fiche, your stuff is easy compared to those :)

I'd be happy to volunteer to edit a book or two myself, but I see Teach has beaten me to it. :)

I may be responsible for one of the additional downloads. I forget which one, but my first try was incomplete, so had to do it again.

But that still leaves a few unaccounted for...

Keep me in mind for future edits. The raws are fine. And using one of teachbug's tips, I'll probably end up converting them to uncompresssed tiff files in any event, making them maybe 3 times bigger!

Well, right now I have 3 books and three volunteers, so you're each getting one!

On the TIFF tip-- there's no benefit to converting from a jpg to a tif. JPG is a lossy format, so once a scan is saved as a jpg, the information is gone. Converting it to a tif at that point just bloats the file with no benefit.

On the other hand, saving the initial scan as a tif has enormous benefits as far as sharpness and clarity are concerned. I was doing that for a while, but the file sizes were starting to annoy me... 8 MB for a single 150 DPI page, etc. Now I scan to jpg at 200 DPI and save the raws at maximum file size before I do any editing on them.

(The scan-to-tif is what I'm doing with the fiche I'm scanning right now, and you want to talk about big file sizes... a strip of 5-6 pages is about 450MB! 1.5 GB for a single 36-page book!)

Thanks pmack, for the TIFF advice. It's good to hang around with experts!

Just to make sure I understand this: I'll usually handle each file at least 3 times, and save each time (straighten, crop, then batch file the edits).

So there's no loss each time I save in jpg format? And here I just upped my RAM to 1.5 gigs to deal with the TIFF files, because they were driving my computer crazy!

Teachbug said...

yeah pmacks is right, if you are gonna do anything with tiffs it has to be the scan as tiffs first, never after.
but if you scan as jpg its ok, I can work with that as well. tiffs make beautiful jpgs when they are done for sure, but I can skip a step and still make a beautiful jpg out of an ugly jpg, no big. also glad that we 3 got the first 3 books :)

I scan as jpg @ 200 dpi, but if you prefer tifs, I can do that for you.

As far as multiple saves in jpg format, you can minimize the compression artifacts by always saving the jpgs with no compression except on the final save. I do a 3-step save as well; each jpg save is at a photoshop quality of 12 except for the final edit which I save at 8. Editing the scans as tifs produces nicer output, but the jpg method can produce fine results, especially with a light Unsharpen Mask right before the last save.

My personal preference is to work in tifs only when the original image is missing a lot of information where you can't really afford to lose more, as in the case of fiche. For flatbed scans, going from 150 dpi to 200 dpi produces a noticeable increase in quality with not a huge jump in file size.

Thanks for the help on this. I'll follow your advice. jpg's is fine by me! Which one do I get to do?
