How to Use Your Flatbed Scanner as Digital Camera
No camera? No problem! Suppose you feel like taking a break from your camera, or maybe it’s just a rainy day and you don’t want to go out and risk getting the camera wet. Then you can use your flatbed scanner (assuming you have one) to make very interesting still-life pictures. In this post Kai Virihaur shows you how to get these interesting images using your scanner and everyday objects.
Your scanner may have settings for both film (transparencies) and paper – then use the setting for paper. Now find some interesting objects, of suitable size to put on the glass plate of the scanner. You could for instance use seashells, flowers, seed pods, pine cones, leaves, pieces of driftwood, or even small instruments like old watches or compasses.
You put your favorite objects on the plate and arrange them in some way that pleases you. Just be careful not to scratch the glass in case you are working with some hard edgy object.
Ouch, now you can’t close the cover! No problem, just leave the cover open. I recommend putting a piece of cloth over your object arrangement instead. This cloth then becomes part of the composition, in the role of (hopefully) matching background. A black cloth is pretty safe, it matches just about anything.

Now run the scanner, and open the resulting image in your favorite image editing software. It doesn’t need to be very fancy, but it is an advantage if you can tweak the image a bit, adjust the contrast and brightness and so on, to make it look as good as possible. And perhaps you decide to crop it. Note: if you made the scan at a high resolution, say 500 dpi or even higher, you can crop it a great deal and still have a well-defined image which is suitable for printing on paper.
If you don’t quite like the image you got from the first scan it is very easy to just lift the cloth and rearrange your objects, or remove them and try something new. Keep doing this until you feel absolutely euphoric about the result!
In case you are an advanced user of image editing software like Adobe Photoshop, you can make marvelous composites by overlaying several scans and then combining chosen parts from different images. I won’t go into detail about how to do this, since it is outside the scope of this brief article, but if you are familiar with image editing software you get the idea.
The quality of the illumination you get from a flatbed scanner is very special. Since the object is illuminated by a long strip of light traveling across the glass plate, it is bathed in a soft, diffused light which can’t quite be reproduced by other methods. If you want to really get into it, you can play with adding extra light sources that shine on your objects from the side.
Experimenting with alternative ways of making images, like this one, will add an extra dimension to your photographic skill, and hopefully boost your creativity.

Absolutely recommended for anyone with photographic desire! Ir can really boost up your composition skills.
Tried it myself. Eternal fun, really…

Nice article, Kai! I tried this a while back and got pollen all over my scanner from scanning flowers. A way to avoid this (and scratches) is to put an overhead projector transparency on it first.

I just tried this last night with some jewelry pieces for my wife’s jewelry business.
The problem that I had: it was blurry. The jewelry pieces were clear pieces but I couldn’t get a clear image. I tried different resolutions (100 dpi and 300 dpi). I’m using a photo scanner (Lexmark 3300 series).
Any tips?

And don’t forget to get some overhead slide transparencies or acetates so you can protect your scanner’s glass from scratches!

I wrote this for JPGmag.com (http://www.jpgmag.com/stories/1564) a year ago I sent this to Darren but I didn´t knew if he got it or not, I have some examples on flickr too, you will see what other things you can do. Check the JPG article :D and post your experiments.

That is very cool, I never thought of using my scanner for something like this. I have always used it for normal things like scanning in documents. Yet another thing I need to try this week.

Please stop publishing your entire articles in the RSS feed. Just place the title and a summary of the article. Also do not place pictures or graphics in the summary.
Thank you!

I’m just chuckling, here, because I actually do the exact opposite. I don’t have a scanner at home, so whenever I need a digital image of a photo or a piece of paper, I take a picture of it with my camera and use THAT! In fact, a lot of time, the photo-of-a-photo looks better and sharper than the scanned version I could get at the office. Go figure.
August 28th, 2008 at 7:26 am
I second you, Deb. Most of the times when I’m at the office and don’t have time to get a photocopy of an important note or memo that I would need to refer to later on at home, I take a photo of it. It’s fast; convenient and most of all….EASY :)

Hi RayPG – sorry but I don’t seem to have got your tutorial. If you have others at any point feel free to shoot them over via our contact form.
August 28th, 2008 at 9:25 am
Sorry Art but we decided to publish full feeds because of public demand (see last week’s post explaining it) – the response has been overwhelmingly positive. I apologize if it doesn’t work for you but it seems the vast majority of readers want it.

The reader needs to be aware that there are differences in scanning technologies. The two primary systems in popular use are CCD (Charged Couple Device) and the CIS (Contact Image Sensor) optical scanning technologies. This might help Todd (above) understand why his images came out blurry.
There are many differences but the one most important to the three-dimensional scanning artist using a flatbed scanner is depth of field. CIS devices have a much shorter depth of field than their CCD brethren. CCD devices have a much brighter, full width Xenon or Mercury Vapor lamp and a front surface mirror to direct the image to the CCDs where CIS devices are LED driven with a single RGB (Red-Green-Blue) LED and a plastic rod lens that directs the image to the sensors.
The results shown in this tutorial are stunning. They are best achieved using a CCD optical scanning system. There is a lot of creative room with the use of ancillary lighting, deeper focus and greater color depth when using CCD scanners.
I have used both. To give an example I stood with my face over both types of scanners and took a self-portrait. A CCD scanner allowed me to be 6†to 8†above the platen and my full head was in focus from the tip of my nose to the back of my ears. When using a CIS scanner I had to put my nose on the platen to record the image. The depth of field was so shallow that even with my nose on the plane of the platen glass the device could not get my eyes in focus. One might ask how large is my nose to cause this (lol). To quantify my test I placed a ruler at a 45-degree angle and was only able to get a three-eights inch (3/8â€) depth of focus on the CIS scanner.
I have been using flatbed scanners to photograph still life for the last eight years and have found that CIS scanners do an excellent job with document scanning but if you want to try your hand at 3-D scanning a CCD scanner is what you will want to use.

P.S. Darren — I have to echo Art from Seattle’s feelings about publishing the full article in the RSS feed. He may have dial-up which makes loading the full article with graphics a l-o-n-g process. I have broadband and do not find the process of loading the feed to be a problem it was just so much more convenient to have a short blurb to filter the chaff from the wheat and target articles that I had an interest in much quicker.
Just my two cents worth. Sorry for the off-topic reply
Cheers,

Hi Darren, sorry about that, I use the contact form mmm but who knows what happend anyway I will try to find something to share again :D
August 28th, 2008 at 11:55 am
what a cool idea!

Nice to see so many comments on my article! And especially interesting was the one from Bilka, where he explains the difference between different types of scanners – which I didn’t even think about since I have never used more than one type, the CCD variety:
…”CCD devices have a much brighter, full width Xenon or Mercury Vapor lamp and a front surface mirror to direct the image to the CCDs where CIS devices are LED driven with a single RGB (Red-Green-Blue) LED and a plastic rod lens that directs the image to the sensors…”
So, those of you who have a LED-type scanner are out of luck I guess.
PS: those of you who followed the link to my site – http://www.a1phototips.com – yesterday may have noticed there were some technical issues then, like the RSS feed didn’t work. I am sorry about that, those issues should be fixed now and everything in fine working shape!

I found this article while searching for photography blogs. I’ve done this in the past and it’s lots of fun! I’ve done several pictures of flowers, and sometimes I use cloth, but I’ve also just put an empty paper box over everything. It fits the screen, and gives a velvety black look to the background.
August 30th, 2008 at 12:40 am
I have taken some wonderful and interesting pictures of flowers and take them in a darkend room and just leave the scanner lid up and that gives me a black background. I then can change the color of the background using photoshop.
I also have used my scanner to take insurance pictures of my wife’s jewerly. I find that the scanner has a greast depth of field. Very similar to using a pin hole camera.
All my scannner pictures look very different from a picture taken with a camera.
I am using an Epson Perfection 1240U Scanner.

TO: Sunnyman ~~
Thanks for your kind remarks about my CCD vs. CIS note; I am glad you found it informative. I hope others did too. You presented some great stuff here. I enjoyed your photographs and your tutorial.
Cheers,

To Bilka –
Thank you! Actually, I am grateful for those appreciative words you wrote about my pictures, which I made for the purpose of demonstrating the technique. I am by no means an expert, just dabbled in it for fun. You, on the other hand, seem to have used this method for making images extensively.
To Jack Lane — how funny, I have an Epson Perfection 1200U also! Bought it a number of years ago, still works fine.

I did this 5 years ago for an online competition and actually won. It was great fun.
Here is the shot that won –

Suzanne – that was an extremely ingenious way of using the scanner method! (Also employs one useful way of improving your pictures which I have also mentioned in one of my Photo Tips: “Framing your shots“!)
No wonder you won that competition.
Interesting to see creative examples of how people use this unconventional no-camera technique…

I can see why it won!

During my high school and early college years I modified an Epson scanner and lugged it around in a backpack to “shoot” on location (because most of my subject of interests are 3D or everyday still life)…I haven’t done any in few years, but seeing what everyone has to say is getting me inspired again!
Some of my photos are uploaded at http://flickr.com/photos/exeunter/sets/1344187/
Needless to say, there are entire flickr groups dedicated to scanography with some amazing photos!
