Want to watermark your photos with such information as camera
model, shutter speed, date photo was taken and the like?
In technical terms, these
information are are called metadata and are stored in some
named data blocks (e.g. Exif and IPTC) of the photo files.
Since version 3.0, BatchBlitz provides a series of macros for
you to retrieve the Exif and IPTC metadata with ease.
For example, to retrieve the camera model info of a
photo, you can use the macro $EXIF_MODEL. As shown in the left image, the
camera model is Canon PowerShot A80.
To view all metadata of a photo, just right click it in the
Files or
Source Images pane, then select option
"Image Properties" from the context menu.

In BatchBlitz, the
Add Text action enables you to watermark
photos with Exif and IPTC metadata.
Suppose we'd like to watermark our photos with a cameral
model text stamp. Choose File
> New to create a new task, then
follow the below steps:
Step 1: Select source images.
In Source view, select one or
more photos into the Source Images
list. These are the photos that will be watermarked.

Step 2: Specify where to store the watermarked
photos.
In Output view, specify a folder
for the watermarked photos.

Step 3: Add an Add Text action.
In Actions view, click button
on the toolbar above the actions list. In the shown
"Add Actions" dialog, check item "Add Text" and press OK.
 |
You can also double-click the empty area of the actions list to
invoke this dialog. |
Now the actions list has an "Add Text" action. Make sure to
activate it by checking the Active
option. See below:

Step 4: Customize this Add Text action.
To edit the added action, just double-click its icon or label.
This invokes the "Action Properties" dialog for the Add Text
action.
Here we need to set the "Text"
entry to "$EXIF_MODEL", or we can insert this macro into the
edit control by clicking the button to the right (as shown below),
then select Exif Info >
$EXIF_MODEL from the popup
menu.

Here we'd like to place the text on the bottom-right corner,
leaving a 20-pixel
margin on the left and bottom sides of the image. See below:

Now let's set the font face and size using the text format
tools. See below:

Click OK to close the "Action Properties" dialog.
Step 5: Start the task.
Now we've got everything ready and we can start the task. Just
click button
on the main toolbar.
The BatchBlitz online documentation provides more detailed
information on the Exif/IPTC macros.
