  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.
