Yes, DVDs have limitations. You certainly wouldn't want to scratch them. True, but they will degrade due to a number of other factors. Environmental factors and manufacturing quality are two major ones. In my case, I attribute it to the application of labels on the DVD's. The ones that had the most significant issues all had a similar label applied. Damage to the label side of the disk can damage the ability to read the disk. |

Pete, thanks for these links! Perfect timing! I am helping a family member who is working on our family history. You're most welcome. I've helped my wife with scanning old prints to post on www.ancestry.com/ |

Hi Andy,
I assume you mean the stick-on type labels. Yes, they are a worry for me as well since they could become loose and start to peel each time they are inserted and ejected from the dvd player.
Fortunately I haven't had any issues with labels so far, but I have very few DVDs with stick-on labels. Since I got my Epson SC P600 printer I have been printing labels directly onto the DVDs (types that can be printed on).
I don't see DVDs as very long term reliable storage mediums but they are very convenient for sharing videos, well for my family and extended family at least.
It would be a waste of time for me to spend too much time trying to "guess" what long term storage technologies will in the future supersede today's technology.
Our kids and grand kids I am sure will be more than able to transfer "valuable" family photos and videos from today's optical and magnetic discs to whatever they feel is more appropriate in 10, 20, 30, 40+ years time

Let's not continue to be myopic and focus on DVDs; the thread is about image storage, accessibility, and preservation.
We've had enough about DVDs [possibly the pros and cons of DVDs should be discussed in another thread] - in my OP I mentioned long term safety and accessibility, whether DNG was a viable file format, and digital data storage in general.

I didn't think Andy and I were being myopic regarding DVDs
In any case, I agree with alexr earlier. Family descendants, or whoever, will be better placed to transfer whatever data they feel is valuable to whatever the latest or most appropriate storage formats and mediums are in the future.
If you make an incorrect choice now on incorrect or poor assumptions it could mean loss of data and/or a lot of double handling and extra work for future generations.
I doubt anyone today will be able to give a 100% unconditional guarantee on the future proofness (if there is such a word ) of any current format/storage technology.
If they can, then I am all ears

Hi sepiana,
You're most welcome. I've helped my wife with scanning old prints to post on www.ancestry.com/Pete, thanks once again! I am the one in charge of scanning old prints. I will check that website.
If you or anyone else is interested in genealogy, www.myheritage.com/ is another web site that might be worth looking at depending on what you are after.
I know a couple of people who have found it very useful and helpful. |

Regardless of how you end up storing your image files, if preserving the accuracy of the image's colours is important then you MUST embed into your image file an accurate colour profile from a properly calibrated/profiled monitor.
If no colour profile is present or if an inappropriate or inaccurate colour profile is embedded, then there is no way possible for anyone viewing or printing your images to be able to reproduce your original image colours. Yes, they still will most probably be close but certainly shifted a little and less saturated to some extent.
