I select the tagged images using apple+T and choose the copy function (apple+Y). The images are copied into a new folder in my system which is named after the job and with a six figure date "jobname-280207" would be a typical folder name and the images are sequentially renamed and numbered during the copy process. The files are named "jobname-neil-001" and so on using a pre-defined job name and the sequential numbering variable in Photo Mechanic.
The contact sheet of renamed and numbered images is then opened (apple+O). At this point I highlight all of the images and undo their tags (apple+-). All images that are the same as one another are selected and the "Stationery pad" is opened to batch caption and keyword the RAW files. This process is repeated for each set of images requiring matching captions using the "apply stationery pad" command after each set.
With Photo Mechanic it is important to use the check box by each box to make sure that the given information is properly added. It is even more vital to mark all images with the copyright holder's information so that if the images are ever in a folder they can be identified as the property of the owner.
Once the stationery pad has been added to all of the images in the set, it's time for the critical edit. Back with the contact sheet I highlight all of the images again before opening a new preview window, going through the tagging process again. This is the final edit and so I make sure that only the images that I want the picture editor to see are tagged.
