I think it would save some time. If the scanner color profile is correct, it should be possible to fix all images in one step as apposed to using level correction in gimp or photoshop on images individually. I'll order a calibration sheet and post sample before/after scans next week.
I figure a few raw/profile corrected/manually corrected comparisons should show if it's worthwile.

Sounds good, thanks Huygens.

I couldn't find any mention in the quidelines of color calibrarion. You can get close by hand, but you have the color inacuracy of the scanner compounded by the color innacuracy of the monitor. Do they mention it somewhere else?

Well I put that up as a guide, we can write our own guide, that seems like it only has to be done once right, by chance have you tried using it and noticed the difference between a regular scan and one color calibrated? The photos do look better after it in the link you gave Huygens. Would follow those steps save time with using Imaging software?

I found this site about scanner calibration
http://www.photographical.net/scanner_profiling2_2.html

Essentially you get a sheet with sample colors to generate a color profile for the scanner, scan with no color/contrast correction and then apply the profile to get accurate colors. It doesn't seem like that much trouble, free software and a $10 calibration sheet.

I was just wondering if anyone here has ever considered creating/extending a database to catalogue game package contents, manual/cover versions etc? Not for the purpose of replacement documents, but solely to record existing versions.
It's hard to figure out what originally came with a game and it will just get harder as time goes by so I think such a database would be helpful.

Dremora was working on it, don't know the status.

I'd say we should be closer to http://www.softpres.org/ - they dump disks _and_ scan all the papers.

Can you give a little more info on why you think it doesn't fit in here?  Like "it goes against redump's purpose statement' or 'it would take up too much of people's time and they wouldn't have any left to dump'.

That's a good idea but i think that has nothing to do with Redump.org... this site should be only to dump the game discs and nothing more... like no-intro but instead of carts we dump discs

May I ask why you think that? I would really like to understand where you are coming from. I must have a misunderstanding of no-intro, I was under the impression they started for the simple reason of removing Scene intros from roms. I know I am just registered over there so I might not have access to everything they do but I was under the impression they find the best roms on the internet and put it in their dats, and when/if a better dump comes a long they would take out the old and put in the new and if I remember correctly one of their High Council even posted in a thread on the old forum, now this isn't verbatim but "When did we get in the business of dumping games". Am I mistaken?

Now on the other hand, as a preservation project if we find out or even suspect a dump is bad we remove it and not just wait till a proper dump comes a long.  As you can't actually claim a game preserved without its supplement information is also preserved (As we are dealing purely with bits of 0 and 1s that would include scans of the supplemented information, cover art, manual, etc.) In the physical realm say the museum of video games wouldn't say we preserved this game when they only had the disc would they? No, unless that's all that remains of that game. 

I think Redump.org is the perfect place for that information, but that is my opinion and really that's all it is. It could also be that I am too idealistic about what we are doing here.

Yes, good scans would be wonderful; it just takes a lot of effort to get a good scan so people might be less willing/able to contribute. I'd say making scan 'preferences' would be good (resolution alignment etc), but still accept anything that serves the purpose. If anyone ever submits a better scan, just replace the old one.

There are quite a few free photo hosts available (photobucket etc) so it might be doable without increasing the database site's bandwidth.

I can understand where you are coming from, I conceive its from the same place I am coming from "human nature" but opposite sides. Humans will take the least resistance path that's why we don't have an army of dumpers as people think our way to dump games is "complicated" or "time consuming"  we are the exception because we have the passion in what we do, I also believe it's because we don't have "preferences" with our dumping procedure but strict steps to follow, of course we could have a bigger database if we was loose with our requirements for dumping games but that's not our purpose its to preserve games.

Same as scanning unless we have strict rules to follow we will get the least resistance (shitty scans) and if we accept it what incentive is there for someone to make the perfect scan? If we make the least resistance perfect scans yes scans might trickle in at first but as we grow in more popularity, maybe more acceptance as the raw material becomes more scarce or lower quality (more vandalism on the material, marked, stickered, lost or thrown away, etc.) same as the games themselves (going to a used game store 3 out of 5 games aren't in dumpable condition meaning most likely there will be glitch some where in game) more people will take up the cause.
