Yeah, CDs are universally accepted by the mainstream so they won't be going anywhere
soon. I'm guessing that you will be able to read CDs for a very long time. The bigger issue
is the environment that you store you media and how you treat it. Even the best CDs will
start to degrade in the wrong environment. I would suggest making more than one copy of
each CD, storing them in a cool dry place and also keeping the images on a hard drive
somewhere just to be safe. Store your images on multiple media in multiple places (on and
offsite) and you should be in pretty good shape.

Yeah, basically you set up your batch process with a starting file and a destination file. The
start file should stay the same and then all your new TIFF files will end up in the
destination file. Before doing a batch process though always duplicate the original file just
to make sure that there are no weird mistakes that overwrite your original images.
Hopefully I answered your question. If not shoot me an email.

I haven't had much experience with Picasa but I would enjoy further conversation on the
subject. Anyone with experience or opinions please post away!

Hans,
I'm not a big fan of archiving in RAW format at this point. I would consider batch
converting your images to TIFF and storing them that way until there is a universal RAW
format suggested like the new Adobe Digital Negative format. Imagine trying to open
those images 10-20 years from now. TIFF is universally accepted and safe.

Yes, I would say that you should never make your adjustments before archiving your
images. The responses above are sound. My two cents... I don't like the idea of archiving
images in RAW at this point. Wait until Adobe get the new DNG format accepted. (See link
below) Since each camera company has their own RAW format it just
lays the groundwork for possible problems in the future when you want to open those files
10-20 years from now. The same goes for jPEG2000. It has not been fully accepted yet as
a format that will stand the test of time. Be safe and save your files as HIGH res TIFFs. As
far as arching goes I am always looking for possible problems in the future. I would like to
believe that Adobe will keep making Photoshop and you will be able to open layered files
in the future but to be on the safe side, don't count on it. I would recommend saving the
RAW file as a TIFF and then modifying another version of that TIFF and saving it. That way
you are sure that your images will stand the test of time.

Has anyone tried Picasa from Google? I just stumbled over this today. I am a Google lover
and tend to think that anything they do is great. As I said though I know nothing about it
and would like some opinions. Maybe we could give it a spin and open a separate thread
to discuss the results.

Yes, iView Media Pro is a great product. It might be a little overkill for you though if you
are just interested in viewing and browsing. There are a lot of great products out there
though. I am personally using iPhoto on the mac which is a decent program and getting
better every time. I keep waiting for Apple to start offering their software on the PC
platform like they have with the iPod.
New net.wisdom about gold CDRs?
in The Digital Darkroom: Process, Technique & Printing

Yes, the answer to the archival question on CD does involve purchasing from a quality
manufacturer and the gold CD's do make a more reliable burn. (more on that in a bit) The
bottom line is that you should never trust your valuable images to just one type of media
at this point. Even if you buy the best media there is a lot more that can affect that media
as it is stored. Humidity, temperature, if you store them flat, plus the speed of your initial
burn affects the quality of the burn, etc. We can go on and on. What you really need to do
is store your images on hard drives locally (yes, more than one) and then back them up to
a high quality CD, DVD or portable hard drive off site. Obviously there are many more
solutions but this is just one that the average photographer can use.
Regarding the gold in the CD...
Behind the information area is a reflective layer used to detect the change in reflected light
intensity every time the laser spot moves from the pit onto the land (the area between
each pit) and vice versa. The change in light intensity is used by the CD player to represent
the data that is stored on the CD.
The most important thing to come away with knowing is that gold disks, although they will
cost you much more, have shown greater permenance in many tests and are the highly
recommended solution for users such as ourselves that are interested in maxium archival
time. Silver corrodes through reaction with sulfur dioxide, an environmental pollutant that
can migrate through the disc with moisture causing the disc to reduce the reflection of the
laser and resulting in the data becoming unreadable. Therfore, silver is a good solution
but for longer therm storage, it is not the best choice for obvious reasons. Gold is
obviously the best choice but is traditionally more expensive. For our purpose here I would
recommend buying nothing but discs manufactured with gold reflective layers and
ensuring that you have taken that extra step to preserve your data.
