I have several important and private documents I would like to try 'scanning' with my digital camera. On or two very quick experiments shows image quality and size are excellent.
Two problems I found though were the yellowing of white paper - I was advised not to use the flash, so the the ambient light colour in the room seems to have dominated. What should I do about lighting? Use an artificial electric lamp with a very white light, or use sunlight in a much more brightly lit room?
My other problem is crinkles and folds in the documents that clearly show in the 'scans'. One's first though is to place a piece of glass over the document to flatten it, but that brings the risk of reflections. Is there some kind of material I can use in place of glass that is highly transparent, but non-reflective? Something I could get from a photography or art shop, or maybe a printing supply shop?
I was going to mention that as well. Many all-in-one printers can scan images. I've found the quality to be good enough and if it isn't, any half-decent imaging software can make corrections without losing much of the original warts and all.

You could always just... you know... use a scanner. It is what they're designed for after all. A cheap 3 in 1 printer is roughly £35 in the UK. I cant see them being much more expensive anywhere else civilised.
I'm a contractor that's been here a month and attracted attention by taking too much leave, and being late from transport problems. I don't think I'll be ordering anything until I release some software.
Just order it and be damned, they'll be awestruck by your balls and not say anything.
Here is an email that I sent to my boss 4 years ago;
Now that we have a 'waterit' e-mail account, it would make sense that we have some sort of method of monitoring this if it is to be useful in catching problems as they develop.
It is relatively simple to connect to the Exchange Server and monitor the various folders we have set up and then display the results of this in a webpage.
This web-page would poll at whatever interval we require and display whatever we want, it could flash if e-mails are received that could possibly indicate an immediate problem, it could display totals so we can see what is going on in various systems.
It would also be feasible to write scripts to monitor activity on the servers so we could see any problems developing with disc space, DB activity, backups or whatever.
If we were to have this setup and working then obviously we need a screen on it, were it to be a normal monitor then obviously that would require someone to walk past and look at it.
What we ideally need is a big wall-mounted screen that is clearly visible from everyone's desk (next to the clock is an area that immediately presents itself.
This would mean less time spent checking things to see how they are progressing, and immediate notification to the room, and thereby to whoever is present and currently holding responsibility to do something.
It would also mean that we could make it flash red, and sound a siren.
This, I firmly believe, would be a good idea.
The response I received was;
Find out the cost (ballpark) and I will do a business case.
And we ended up with a big telly in our office that had freeview and could quickly be switched to the monitoring screen should the need arise. We never did get around to creating anywhere near as exciting a monitoring suite as described.
But at least we had the equipment to do so at some point in the future.

Well, what I usually do is pin the paper to a cork board or similar (to keep it flat), set the white balance in the camera based of the paper I'm shooting (if you don't have a manual white balance setting just pick the closest preset) and take the shot. If I can be bothered I'll even put the camera on a Tripod so that I can line up the paper properly.
As for the pins in the corner of the page I just edit them out after.
If using a tripod you don't need to worry about having a bright light shining on your papers (which may cause shadows on some creases) since you can just allow the camera to use a slower shutter speed.
Well I've used iPhones and now a Windows Phone, and I rarely install apps. So even if I had an Android phone, I'd not install this. I only use the browser and email apps irrespective of the phone I use!
I don't know much about IE on Windows phone but Safari on the iPhone is terrible, when I was on iOS I avoided it at any cost. Any particular reason for avoiding apps or you're just too lazy to be arsed into installing any?
Part of it is being lazy, the other bit is I am not very tech-savvy when it comes to using gadgets (mostly due to lack of interest). Kinda ironic I guess given that I spend most of my time writing code, including on mobile devices.
That said, I did get a Nexus 7 for my son and helped him install several games. So I am familiar with Google's app store.
I set the camera on a tripod and use long exposure times. I've succeeded in 'scanning' even nearly unreadable papers using this method. This works even in a dark room, given the exposure times are long enough, and the sensor in your camera is powerful enough.
I use a DSLR though, but I presume that even a point-and-shoot camera should be able to produce good results.
PS: You'll need to do some post processing. But it will be simple enough, and you could get it done with something like Picasa or Paint .NET.
I've never had much luck with that, Brady. Glare, color shifts, keystoning, or some other damned thing always interferes. The best I've managed so far happened yesterday, when I needed to get a signed document on company letterhead to a government agency in a hurry. The scanner isn't working, the document is in Word format, and the fax machine is too poor quality to serve. So I signed the printed document, photographed my signature with my phone, emailed the picture to myself, cropped, resized, rotated and color-corrected the image on my desktop, then pasted it into the Word document. It looked as good as the original, so I pdf'd it and emailed it off, and no one has questioned its validity.
I do plan to keep my signature file locked in my safe, on a thumb drive, and no images of it on my desktop.
It's typically a very manual feature on most new cameras. I've pulled off some great shots using it. My professional photographer friend showed me that he carried around a white sheet of paper in his pocket. When in strange or bad lighting, he would whip it out at arm's length to set the white balance, then get his picture.
I didn't mean it in a mean way, I'm just surprised at the amount of people that discuss the same issue on all sorts of forums, and rarely do people ever mention this feature.
My biggest problem is paralax. I can't seem to get the picture parallel to the document. It always looks skewed; now that is going to take a tripod, which will only happen after payday, or just lots of practice, and a trip to the local print shop for the currently needed scan. It's still interesting though and I will continue as a little hobby.
