You will also need two blank text files called 'explore.txt' and 'out.txt'. First of all, you will need the stand-alone Windows version of the EXIFtool program. This time, we will explore what other information is available in the EXIF and IPTC tags of your photographs, and find out how to create a list of selected tags that you choose as important to you. In the last Travel Photographer Tutorial, I showed how to use ExifTool to create a list of photo-sizes. It can also produce a file that contains tag information from images in a given directory, and all sub-directories, which is the way that we are using it here. ExifTool can access and update all of this information, if you use the right commands. It is the space that you write to when adding a Description, Location or Keywords to your images, prior to submitting them to a Photo Agency. Meta Information lists all kinds of interesting information that is hidden away in each of the photographs you take, such as when it was taken, the aperture used, the shutter speed used, flash information, and much much more. It can read and write the Meta Information in your photographs. What is ExifTool? It is a stand-alone Windows program written and kindly made available for free by Phil Harvey. Don't worry! This Tutorial will explain everything you need to do, and how to do it, in the simplest of terms.
Unless you have been working with computers since the 1980s, these may be unfamiliar tools, and apt to fill today's computer user, more familiar with the mouse and the icon, full of dread. Unfortunately it has no GUI (Graphic User Interface) so you will need to action it using the Command Prompt, or a DOS BAT file.
This tool, called 'EXIFtool', can be downloaded for free from the EXIFtool homepage. I used a readily-available automated tool that can scan an entire folder or directory, and produce a text file with all the information that we needed in it. In my last Travel Photographer Tutorial, I explained how to create a list of the dimensions (pixel width and height), of every photograph in a folder: an essential requirement if you are setting up a database of your own portfolio of photographs.
