## ExifTool Verbose Option

With the Verbose option enabled, ExifTool prints a verbose log to the console as it extracts the meta information from a file.

The -v option of the exiftool application allows control of the Verbose setting. A number between 0 and 5 may be specified with the -v option to set a specific Verbose level. For example, -v2 sets Verbose = 2. Without a number, -v increments the current Verbose level by one. Multiple -v options are allowed, so the following two examples give the same result:

>     exiftool -v -v -v t/images/Canon.jpg

>     exiftool -v3 t/images/Canon.jpg

Below are example outputs for different Verbose settings.

### Verbose = 1

Prints tag names and extracted values. These are the raw values straight from the file, before any conversions are applied. Also printed are details of the file and directory structure:

>       FileName = Canon.jpg
>       Directory = t/images
>       FileSize = 2697

### Verbose = 2

Prints all of the information from Verbose = 1, plus additional information about the tag ID, data size and format:

### Verbose = 3

Adds a hex dump of the binary data associated with each tag. The hex offsets are relative to the start of the file, unlike the default HtmlDump output where offsets are relative to the start of the TIFF header (the native base for TIFF/EXIF offsets). If the data is very long, only the first few lines of the dump are printed:

### Verbose = 4 and Verbose = 5

These Verbose levels give similar output to Verbose = 3, except that with level 4 there is no limit on the length of data dumps of tag values, and with level 5 the limit is also removed for dumps of JPEG segments. Note that the output may be very long at these levels.
