keep all metadata fields

[EugeneD]

Hi,
I know, the question "Why is my image smaller after I use ExifTool to write information?" is explained in FAQ already. I have another question (may be little bit paranoid  ) – is there any possibility to disable the optimization (not to change the structure of metadata - to keep ALL fields, does not matter whether they are used or not and change only the field I want to change)? 

Regards

Hi Eugene,

By "fields", if you are including unused space in the file, then no, there isn't an option to preserve this when writing.

Hi Phil,

thank you for the prompt answer. I asked the question, not because I want that  my photos waste more space as they really need. I have just thought, there is surely a reason, why the manufacture (Nikon in my case) reserves these "dummy" blocks and that any software (for example from Nikon itself) could get problems if it does not find the structure it expects.

Hi Eugene,

If you're worried about corrupting your images, worry more about using Nikon software than ExifTool.  (read here)

Hi Phil,

fortunately I do not use Nikon Transfer  ,  may be sometimes  Capture NX2. By the way, something about 30 jpg files, changed with ExifTool I have opened with Capture NX2 without any problems.
I asked the question not because something was wrong, it was only just a thought as I saw that ca. 20kB from every file have suddenly disappeared.
Thanks again for the answer.

Regards

Eugene
