digital photos

[aeh]

This probably is the wrong forum, but couldn't find one close. Anyway, I have a

question about digital files -- "does draging and droping jpeg photo files

several times into different folders cause any loss in quality? Thank You for

any info I can get, Al

Maybe digial darkroom would have been a good forum, but either way the answer will still be no. Only opening and resaving loses quality merely moving around on the hard drive does nothing.

You can move or copy without changing the file at all. If you open it, make _any_ changes,

and then save you will lose quality with jpg.

Al,

 

Which of these two changes a sandwich?

 

1) Moving a sandwich from one plate to another.

 

2) Eating the sandwich.

You can open and close it as many times as you want without any change. If you re-save,

even without making any changes, there will be some degradation.

With most programs you can do a lossless rotation (say landscape to portrait) of jpeg.

Rob... the problem with your analogy ("moving a sandwich") is that both change the sandwich. One less than the other (depressions in the bread, loss of filler, dropped crumbs vs. major removal of portions), but I think when it comes to digital photography we usually talk about pretty subtle changes.

 

The actual answer is still "no," of course. ;-)

Thank You all for the speedy replies. That was more or less what I suspected. Just needed more experienced imput, and I thank you, Al

There's nothing wrong with my analogy, only your understanding of its intended recipient.
