If I use MC's "Rotate" function, will the images lose resolution
Actually, my question was nothing to do with being lossless or not, though thanks for answering it.
These two statements are contradictory.
Lossless means by definition that you don't lose anything (hence, loss-less or "without loss").
If you happen to lose the "name" tag (only when it's blank and I haven't verified this problem), that is a change in MC's database
not in the image file itself (therefore still lossless as far as the image file is concerned). The reason this is important is because once you make a lossy change to the actual image file, the data is gone and it can never come back. (You can decrease resolution, but you can never
accurately increase it.)
Just a quick second question to those in the know:
Does adobe applications use some kind of industry wide standard for its rating tags etc. in images? Does such a standard exist?
The state of
metadata tagging in Images is kind-of a nightmare. However, there are some standards including
EXIF and some standard
TIFF extensions which are somewhat similar to the ID3 tags in MP3 files. Unfortunately, the image management and editing companies out there (Adobe I'm looking at you) have modified these "standards" so much that there really isn't a standard anymore. The problem is that there is a standard way to add tags to images, but each manufacturer calls the tags different things (and some keep changing their minds). There is supposed to be a tag naming standard (called
Dublin Core) but no one seems to be comitted to following it quite yet.
