-- JodyHarris - 31 May 2007

Setup:

• Set camera to small/normal
• Set camera to not power-off
• set up .gphoto2/settings with --auto-detect (This only has to be done the first time, or if different cameras are used.)

Capture an image:

NOTE the filename! So far, I've found that the filename must be set in the command line.

Helpful info:

Problems to address:

• any external light source is going to screw with the images
  • you can gel the strobe/s to match the ambient light
  • you can not worry about it since these are effectively snapshots anyway
• "stand here" You'll need to give a clear indication of where the target area is.
  • make an actual booth for the subjects to crowd into like a traditional photo booth
  • make a "reverse frame" to help them align their faces in (I'll try to draw up a diagram of what I'm thinking of)
• Power -- the camera will be on the whole time. You'll have to set the camera to not shut off.
  • Have a spare battery and check the booth every half-hour, switching and recharging the camera/strobe batteries as needed
  • external power supplies? (expensive!)
• Printing -- wide open. What are your thoughts?

Image Manipulation

Other thoughts

• you'll have to let the subjects know how many shots to expect.
• Some kind of visual counter would be nice (you would have to make the/a computer monitor visible in the booth)
• How to trigger the session? "hit the space bar"? show a countdown?
• I would think hiding as much of the 'back end" as possible would be to your advantage.

• One thing that occurred to me, and is attractive to me, and fun is that you can slap a custom logo on each image, or on the image set (or both).
• You could slap your logo on it by default,
• or offer to create and slap an event logo on it.
• Choose to slap both your logo and the institution/event logo on.
• Depends on how you're approaching the whole thing and if some point you wanted to use the photo booth to promote your business or not... lots and lots of options there.

• I have a script that I wrote to "slap" my sign on photos.
• I have a script I wrote for creating "posters" with stuff on them.

• Consider indexing all of the images and storing the originals. There is a possibility that someone would like to get prints of some frames.... There would have to be some kind of rules for how long to keep them, I suppose.

Notes:

2009-10-27 I must have been dreaming because this morning the capture script no longer takes the 6 images. It is capturing a single image and stopping failing to even download it. I suspect it is something where the camera settings changed. This thing may be really twitchy...

2009-10-28 JHH

• Possible display option: gconftool-2 --type string --set /desktop/gnome/background/picture_filename /path/to/image.jpg
• This will set the image as the global desktop for Gnome. (There are different ways to achieve the same thing in other window managers.)
• You could run the photo booth script in the background somewhere and show the users a blank screen. The desktop could be changed to display the latest montage.
• You could cycle back to some default image after some time-out, or some kind of slideshow...

feedback:

It started as just a simple guide to setting the Canon 10D to take better photos. At first that was enough. Then, more and more people started writing better and better software for Linux Digital Photographers. At some point, the Linux information outgrew the Canon 10D page. So, here and I am trying to bring some balance.

Please send me feedback on the stuff I miss. The field of Digital Photography and Linux is changing very rapidly, and I can't keep this up to date without help.

Background:

I've been running Linux as my primary desktop OS since August, 2001. I'm very happy with it, so I was not interested in being slaved back to a Windows box to use my digital camera. Happily, new tools for processing digital images and RAW digital images are being made available to Linux users every day. Now, Linux can satisfy 100% of what I need for post processing of digital images.

For the first year I owned my Canon EOS 10D, I shot in Large, Fine JPEG only (no RAW images). In June 2004, I started shooting RAW when I had the oportunity to be a beta tester for Bibble Labs. With BibblePro 4, I can convert my RAW digital images on my Linux box, and life is very good. I was shocked to discover how much more information the RAW digital format stores at 16-bits per channel than JPEG at only 8-bits per channel. I'm not likely to ever return to the limitations of shooting JPEG.

Organizing images

KPhotoAlbum (formerly known as KimDaBa):

I highly recommend KPhotoAlbum (formerly known as KimDaBa - K Image Database). KPhotoAlbum allows me to categorize and organize images quickly, and in any way I want. I can put all the information on 100 images (location, keywords, people, event) in less than 15 minutes. I'm very pleased with it.

Versions up to 1.1 do not support RAW image conversion. As of version 2.0, KPhotoAlbum does some RAW conversion, but it is limited and not completely tested. I continue use a parallel tree of JPEG "thumbnails" of all my digital images for managing, organizing and cataloging. I include KPhotoAlbum on this page because KPhotoAlbum is unquestionably the best tool for digital image cataloging, sorting, and searching I've ever seen. KPhotoAlbum is already included in many of the Linux desktop distributions.

Google Picasa

Google's Picasa has excellent photo management tools built into it. (wikipedia page) I have not made much use of them because of my huge time-investment in KPhotoAlbum.

digiKam

digiKam is also a well-developed photo management tool. (wikipedia page) Again, I haven't used it's photo management tools.

F-Spot

Oh, yeah, and F-Spot... (wikipedia page)

RAW Images:

Some people have the desire for the most accurate possible images. For them, shooting in RAW digital mode is their only option. Here, I attempt to present a comprehensive set of Linux tools for people who want to take advantage of RAW format digital images....

dcraw:

David Coffin's dcraw is, to my knowlege, the first RAW converter for Linux, and the backend for a whole array of RAW converters. At this point, you'll have to compile it yourself. I know that Robert Krawitz has done some good work extending dcraw. I will link to his work when he has some information on it. In the mean time, you can grab a copy of his version of dcraw from here. (Again, it's source, follow the compile instructions from David Coffin's page.)

The images resulting from a dcraw conversion will appear dark and flat until you apply a color profile to them. See Little CMS

ImageMagick:

As of 6.0, ImageMagick has been able to convert (some) RAW digital formats. I do use it to convert Canon's CRW files. Agains, as with dcraw, the images are rendered dark and flat until a color profile is applied. ImageMagick is not able to apply the color profiles internally, so I export them as TIFFs, and use Little CMS to apply a color profile.

LittleCMS:

LittleCMS is a "free color management engine in 100K." Little CMS is, specifically, a C library, but they also ship tifficc and jpegicc runtimes which you can use to apply ICC or ICM profiles to digital images. This is handly if you have programs, like dcraw or ImageMagick, which don't support color profiles. I have found that liblcms SUSE Pro 9.2 installed this package, which included the tifficc and jpegicc runtimes, by default.

LittleCMS is included on SUSE as "liblcms" and "liblcms-devel." It is apparently required by ImageMagick and the Gimp as well as other packages. I guess it's just one of those "hidden treasures."

BibblePro and lite - Bibble Labs:

Bibble Labs has released a new version of BibblePro (4.x). BibblePro 4.x runs on Windows, Mac and Linux! I am very excited about this product. I had the pleasure (and pain) of being involved in the beta testing of this product, and I can say, it's great! It is commercial software, so it's not free, but Bibble Labs does give you a 14 day trail before you have to decide if you want to pay. Being able to shoot in RAW digital and do all of my work in Linux is just pure joy. The people at Bibble Labs are very responsive to their customers, and they are even considering adding features that only Linux users would seriously ask for (like making many of the functions available from the command line for scripting).

RawView - Through-the-Lens.net:

RawView is "an extremely small Java program which allows you to view a variety of raw-files from digital cameras and batch convert the images to JPEGs." Thanks to Ananda Debnath for pointing me at this product.

Alternate 10D color profile:

Someone posted a link to this page by "Ture Pålsson, Lysator," which contains a link to an alternate color profile for the 10D. I don't understand lots of things, but the colors from this profile seem to be better than those that result from the original profile that Bibble Labs has assigned to the 10D. The site also shows how to apply a profile to an image generated by dcraw or ImageMagick using the LittleCMS tifficc runtime: An example workflow could be dcraw -4 -c -w CRW_0123.CRW | pnmnorm -bpercent 0 -wpercent 0.1 -brightmax | pnmtotiff >temp.tif tifficc -i eos10d-linear.icc temp.tif CRW_0123.tif

[UPDATE 30.Mar.2005] **** After sending off almost 200 images that I used this profile, LittleCMS and dcraw to create, I have come to the conclusion that this profile is not acceptable for prints. I have located three places with Canon EOS 10D color profiles. One of which gives them away for free, but they are not LittleCMS compatible. The other two places charge for the profiles, and I haven't decided if I really want to risk even as little as $15-25 on profiles that may turn out to be useless.

I'll keep you posted.

[UPDATE 01.May.2005] **** Got a note from Stephen Tweedie concerning the profile:

The problem I'd expect to see, given what I've seen of the workflow and how the profile was prepared, is one of clipping. Canon raw encodes for about a stop of headroom --- the highest values in the raw file are approximately 200% brightness, not 100%.

So if you're only using up to 100% exposure in your scene, then you're only using values up to 50% in the raw. And ICC profiles are usually really bad at dealing with that --- they really, really want everything to be relative to 100% white for the current profile, not relative to 50% white. If they see 50% in the raw, they will map that to grey, not white, in the output profile.

That's where pnmnorm comes in: it will expand the "normal" exposure of the raw file to fill the full 16 bits of the pnm file, so that the icc transform really maps white to white.

But this is completely the wrong thing to do, because highlights in the scene are going to get fully expanded in the final output, which compresses the tonal range of the rest of the image; in reality, you want to either clip or compress highlights.

The default behaviour of pnmnorm also looks totally incorrect in the way it normalises each colour band separately. If the highlights aren't pure white, then that necessarily introduces a colour shift into the image.

So with better normalisation/clipping, the profile there may well be usable.

On his suggetion, I finally managed to get Cinepaint to compile and run, and the profile works fine there. See the rest of my notes on cinepaint

RawPhoto in GIMP-2.2:

[updated 01.May.2005]
Gimp 2.2 does include RawPhoto? for opening many (most?) RAW formats. it seems to work fairly well. At least on my system, it's a little rough, but it does work. So, you now have direct access to your RAW photos from within the Gimp. You still can only work on them in 8-bits per channel, but you can at least open them directly.

Cinepaint (v0.19):

[Added 01.May.2005]
The CinePaint Project: "!CinePaint is different from other painting tools because it supports deep color depth image formats up to 32-bit per channel deep. For comparison, GIMP is limited to 8-bit, and Photoshop to 16-bit."

On Stephen Tweedie's suggestion, I made another pass at getting CinePaint to compile and run. I had tried and failed before, I tried and failed again, but after several attempts, it finally came up running. Maybe I'll be able to post some more useful information later, if I can get a better handle on using it.

The Good:

• It will let you work on your images in 16-bit colors. (and higher, when those cameras eventually become available).
• It will open some (I have no idea how many) RAW formats directly. I've only tested it with images from my Canon EOS 10D.
• It supports ICC profiles for image, monitor and printer.
• It lets you chose the working color space.

The Bad:

• Good luck finding an RPM for your distro. I think you can get them for Red Hat and Mandriva. It'll also be available for Debian and Ubuntu distros.
• If not, you'll have to compile it on your own.
• I took me a while (several hours) to get 0.19 to compile.
• CinePaint is the recipient of the old, brain dead Gimp 1.x interface. (yuck!)
• Very few advanced tools are available.
• It crashes periodically
• because of the obtuse nature of the UI and hotkey selection, working in it is very slow, at least at the start.

BUT IT DOES WORK, AND IT DOES ALLOW YOU TO WORK IN 16-BIT COLORS!

Perl Tools:

Perl now offers a wide selection of tools for working with images. I have not used most of them. I will document them as I use them.

Image::Magick:

This package is notoriously painful to install UNLESS you install it from your distribution. All of the methods available though ImageMagick are available through Image::Magick, or "!PerlMagick." It is also painfully poorly documented. The documentation is available through the ImageMagick web site: !PerlMagick documentation. In spite of the pain, I find that I love to use this tool.

Google's Picasa:

[updated: 08.Jul.2007; added: 29.Jul.2006]
It's free, it's slick, it does a pretty good job of converting RAW (at least as far as my tests have gone), the colors and tones are as different as any of the other converters, so you may or may not like it. The "I'm feeling lucky" button is about as hit-or-miss as you would expect, but if you're in a hurry, it hits more often than not.

[updated] Gripe: I don't know if this has affected other Linux users. I don't know if the programmers are working on it or not, but when I right-click the Picasa icon in the toolbar, and request it to shut down the background process that watches for new photos, I get a runaway process by the name of Picasa2 which consumes all available processor power. I have to kill it manually to get it to exit. (This seems to be fixed in the current version)

Picasa for Linux is mostly just Picasa for Windows with a lot of custom tweaks done to Wine to make it run. it actually runs very well, and the work on Wine, to my understanding, will be flowing back out to the wine community. That's all good. I'm not one to demand that everything be native Linux, but I do demand that the software I run behave in a predictable manner.

Meta data (EXIF headers):

metacam:

Some kind soul pointed me toward metacam. metacam will spit out the EXIF data in a nice, human readable format, or in XML. Cool, handy, easy, useful

jhead:

jhead is a powerful an popular tool for working with EXIF tags. Not only will it list out your EXIF tags, but it also offers thumbnail removal, lossless JPEG rotation and EXIF tag copying (from one file to another).

ImageMagick EXIF handling:

ImageMagick's identify tool can extract EXIF data. See the main ImageMagick documentation for information. Look under "-format."

Perl and EXIF information:

Perl now offers a good selection of tools for working with EXIF tags, including tools for writing EXIF tags into images.

Image::Magick:

See my notes earlier about the pain in installing Image::Magick.

Image::Magick can glean some EXIF data from image files. I've found that I use the other tools listed here more often than not.

Image::ExifTool:

My buddy Brian pointed me at Phil Harvey's ExifTool, which also includes his Perl library Image::ExifTool. If you're a Perl hacker, and you like to combine your photography with your Perl, you'll enjoy Image::ExifTool. The documentation is a little lacking. I need to write up what I've learned that makes things easier as well as some examples and send them back to Phil. He has done a great service for Perl hackers who like to dig into their Exif headers.

Image::ExifTool is available via CPAN.

Image::MetaData::JPEG:

Image::MetaData::JPEG is a tool to "read/modify/rewrite meta-data segments in JPEG files, which can contain comments, thumbnails, Exif information, IPTC information and similar data." You cannot use Image::!MetaData::JPEG to edit the MakerNotes, but you can modify all of the standard EXIF headers with it. The documentation is verbose. The interface is pretty straight forward. I use this module to copy the standard EXIF data from Canon's THM file into the JPEG files I create for organizing and managing photos.

Image::MetaData::JPEG is available via CPAN.

IMPORTANT NOTE: Think twice before restricting write access to a web or a topic, because an open system where everybody can contribute is the essence of WikiCulture. Experience shows that unrestricted write access works very well because:

• There is enough peer pressure to post only appropriate content.
• Content does not get lost because topics are under revision control.
• A topic revision can be undone by a member of the TWikiAdminGroup if necesssary.

UnknownUser is a reserved name in TWiki. If the UnknownUser appears, it is probably because author information for a topic could not be recovered, perhaps because a topic has been modified by a non-TWiki tool.

User Form

Note: This is a maintenance topic, used by the TWiki administrator.

This form defines the form of the home pages of registered TWiki users listed in TWikiUsers.

Note: Please keep the TWikiRegistration form and this form definition in sync. When you update this form you need to edit/save the NewUserTemplate topic. This ensures that the fields are in the right order.

Header of User Homepages

Note: This is a maintenance topic, used by the TWiki administrator.

The part between the horizontal rules gets included at the top of every TWikiUsers homepage. The header can be customized to the needs of your organization. For example, show all frequently used fields from the UserForm on top, followed by a personalized portal. The portal can pull content from other places, such as headline news by department, a list of current projects, etc. The TWiki:TWiki.UserHomepageSupplement has some additional documentation and ideas on customizing the homepages.

Web Changes Notification Service

Each TWiki web has an automatic e-mail notification service that sends you an e-mail with links to all of the topics modified since the last alert.

Users subscribe to email notifications using their WikiName or an alternative email address, and can specify the webs/topics they wish to track using one of these bullet list formats:

three spaces * [ webname . ] wikiName - SMTP mail address
three spaces * [ webName . ] wikiName
three spaces * SMTP mail address
three spaces * SMTP mail address : topics
three spaces * [ webname . ] wikiName : topics

In the above examples, topics is a space-separated list of topic names. The user may further customize the specific content they will receive using the following formats:

• Specify topics without a Web. prefix
• Topics must exist in this web.
• Topics may be specified using * wildcards
• Each topic may optionally be preceded by a '+' or '-' sign. The '+' sign means "subscribe to this topic" (the same as not putting anything). The '-' sign means "unsubscribe" or "don't send notifications regarding this topic". This allows users to elect to filter out certain topics (and their children, to an arbitrary depth). Topic filters ('-') take precedence over topic includes ('+') (i.e. if you unsubscribe from a topic it will cancel out any subscriptions to that topic).
• Each topic may optionally be followed by an integer in parentheses, indicating the depth of the tree of children below that topic. Changes in all these children will be detected and reported along with changes to the topic itself. Note This uses the TWiki "Topic parent" feature.
• Each topic may optionally be immediately followed by an exclamation mark ! or a question mark ? with no intervening spaces, indicating that the topic (and children if there is a tree depth specifier as well) should be mailed out as complete topics instead of change summaries. ! causes the topic to be mailed every time even if there have been no changes, ? will mail the topic only if there have been changes to it. This only makes sense for subscriptions.

For example: Subscribe Daisy to all changes to topics in this web.

   * daisy.cutter@flowers.com

   * daisy.cutter@flowers.com: Web*

   * TWiki.DaisyCutter: Petal* (1) TWiki.WeedKillers (3) Pretty*Flowers

   * TWiki.StarTrekFan: Star* - *Wars - *sInTheirEyes - *shipTroopers

   * daisy@flowers.com: TWiki.NewsLetter?

   * buttercup@flowers.com: TWiki.NewsLetter! (1)

   * TWiki.GardenGroup: TWiki.AllNewsLetters? (3)
   * petunia@flowers.com: - TWiki.ManureNewsLetter

If a TWiki group is listed for notification, the group will be recursively expanded to the e-mail addresses of all members.

Tip: List names in alphabetical order to make it easier to find the names.

Note for System Administrators: Notification is supported by an add-on to the TWiki kernel called the MailerContrib. See the MailerContrib topic for details of how to set up this service.

Note: If you prefer a news feed, point your reader to WebRss (for RSS 1.0 feeds) or WebAtom (for ATOM 1.0 feeds). Learn more at WebRssBase and WebAtomBase, respectively.

Main Web Preferences

The following settings are web preferences of the Main web. These preferences overwrite the site-level preferences in TWiki.TWikiPreferences and Main.TWikiPreferences, and can be overwritten by user preferences (your personal topic, eg: TWikiGuest in the Main web).

Web Preferences Settings

These settings override the defaults for this web only. See full list of defaults with explanation.

• Web settings:
  • Set WEBTOPICLIST = Users  |  Groups  |  Changes  |  Index  |  Search  |  Go
  • Set WEBBGCOLOR = #FFEFA6
  • Set SITEMAPWHAT = Welcome to TWiki... Users, Groups
  • Set SITEMAPUSETO = ...see who is registered on this TWiki
  • Set SITEMAPLIST = on

• Default template for new topics for this web:
  • WebTopicEditTemplate? : Default template for new topics in this web. (Site-level is used if topic does not exist)
  • TWiki.WebTopicEditTemplate: Site-level default topic template

• Comma separated list of forms that can be attached to topics in this web. See TWikiForms for more information.
  • Set WEBFORMS = UserForm

• Users or groups who are not / are allowed to view / change / rename topics in the Main web: (See TWikiAccessControl). Remove the # to enable any of these settings. Remember that an empty setting is a valid setting; setting DENYWEBVIEW to nothing means that anyone can view the web.
  • Set DENYWEBVIEW =
  • Set ALLOWWEBVIEW =
  • Set DENYWEBCHANGE =
  • Set ALLOWWEBCHANGE =
  • Set DENYWEBRENAME =
  • Set ALLOWWEBRENAME =

• Users or groups allowed to change or rename this WebPreferences topic: (e.g., TWikiAdminGroup)
  • Set ALLOWTOPICCHANGE = TWikiAdminGroup
  • Set ALLOWTOPICRENAME = TWikiAdminGroup

• Web preferences that are not allowed to be overridden by user or topic preferences:
  • Set FINALPREFERENCES = NOSEARCHALL, ATTACHFILESIZELIMIT, WIKIWEBMASTER, WEBCOPYRIGHT, WEBTOPICLIST, DENYWEBVIEW, ALLOWWEBVIEW, DENYWEBCHANGE, ALLOWWEBCHANGE, DENYWEBRENAME, ALLOWWEBRENAME

Help on Preferences

• A preference setting is defined by:
  3 or 6 spaces * Set NAME = value
  Example:
  • Set WEBBGCOLOR = #FFFFC0
• A preferences setting can be disabled with a # sign. Remove the # sign to enable a local customisation. Example:
  
  • #Set DENYWEBCHANGE = UnknownUser
• Preferences are used as TWikiVariables by enclosing the name in percent signs. Example:
  • When you write variable %WEBBGCOLOR% , it gets expanded to #FFEFA6
• The sequential order of the preference settings is significant. Define preferences that use other preferences first, i.e. set WEBCOPYRIGHT before WIKIWEBMASTER since %WEBCOPYRIGHT% uses the %WIKIWEBMASTER% variable.
• You can introduce your own preferences variables and use them in your topics and templates.
