JPG durability (Page 3): Yes, the original conversation was about losing detail in JPEGs. Illogical as an explanation as to why the company does not want JPEGs. The TIFFs, RAW, etc.

What would be illogical in what I said? Of course all files are subject to LOSS if media fails. Files can also be corrupted so they are not readable. But the original conversation was about a photographic image losing detail and other IMAGE properties.

Illogical as an explanation as to why the company does not want JPEGs. The TIFFs, RAW, etc. would be just as susceptible to loss if the reason was media.

NOT True you can open a jpg as much as you want to view ! what they really mean is Every time you ( save ) a JPG file there will be some loss in quality after a period of time Mike

Based on your comment and with really know the host of this company, I get the impression "they" want the RAW images and in turn not give the photographer the rights or credit he or she deserves. I would avoid this scam.

I think we all agree that merely opening a JPG does not degrade it. However, the OP said that the archive doesn't accept JPG's, not that they wanted RAW files.

Correct, a possible erroneous assumption.

What WILL they accept?

What if you open a JPG and never close it?
What if you down load a jpg and never open it. How will you know if it degrades over time.

Since the original question was answered on page one, two, and three, I figured it was time for some new ones.

Is it really open?
Is it a picture of Schrödinger's cat?

NO! if that were the case my web site pics are jpeg you can look as often as you want it is not the case with TIFF or RAW open or save of course one would not use RAW files they need to be processed .

A JPEG does not change even when saved. Only if a change has been made to the image is a Save done.

ANY save changes the file. A close does not.

Why do people type without punctuation we would not know were thoughts end and begin with punctuation it is so much easier to read stuff when it is punctuated it doesnt require rereading to figure where the punctuation MIGHT be to make it easily understandable one should use punctuation
