Making a PDF "print" of photo image with EXIF metadata

Introduction 

JPEG photos will contain EXIF metadata which gives information about the time and date the photo was taken, the phone/camera model used to take it, and other data including the technical settings such as ISO number and focal length. It is important that the JPG file itself is preserved so that the full metadata can always be examined, but also, particularly if the JPG photo was not taken with a setting which stamped date/time stamp in the image at the time it was taken, it is important that the file is printed to a PDF (or captured in a screenshot) in such a way that metadata is shown below the image - so that the date and time the photo was taken can be seen at a glance. This should be done in a way which makes it obvious how the PDF "print" was produced and should show a reasonable size image with EXIF data below all in a single PDF in portrait orientation. 

The reason why it is important  that image and EXIF data should be shown together in a single PDF - or in a screenshot of a single window (rather than having the EXIF data shown in one window and the image in another window) - is that if there are two  separate windows (or two separate PDFs) that does not prove that the metadata in one window is actually from the same JPG as the image displayed in the other window. Of course any proof is relative: ultimately any computer data can be forged but deliberately putting forged evidence before a tribunal is a serious crime which is rare. Having image and EXIF data together in a single window, or in a single PDF, at least establishes that the image from one JPG is not being accidentally shown with the metadata from a different another JPG.

Although EXIF data is often the main focus, the file-system "date/time last modified", if the same as the EXIF date/time taken, can provide some reassurance that the JPG photo has not been altered since it was taken (by an app which does not record the update in EXIF data). However if the file being "printed" is not the original JPG on the original device it was taken on, but a copy on another device, "date/time last modified" may, depending how the copy was done, simply reflect the date/time of the copy and not necessarily indicate that the JPG photo has been altered after it was taken. The filename may provide corroboration if it is in the yyyyMMdd_hh.mm.ss format (rather than in the IMGnnnnn format).     

There are not many programs available which show EXIF data together with a reasonable sized image. Many programs which show EXIF data do not show the image or only show a thumbnail image. In fact there is only one program that I can suggest which can do this (see below). If you know of any others, please tell me. it is important to note that some other apps will display the ordinary file-system date/time if the EXIF date/time data is missing  without giving any obvious indication that that is what they are doing. It is important that any app which is used gives a clear indication if EXIF date/time taken data is missing rather than automatically substituting the file-system date in the display.    

Create a PDF "print" using Acute Photo EXIF Viewer

Acute Photo EXIF Viewer is available for Windows computers and can be used both for any JPGs on the computer itself and for JPGs on phones, tablets, and SDCards by plugging into the computer. If the JPGs are on a phone or tablet which, for some reason, cannot be plugged into the computer, you could, instead, create (on the phone/tablet) a ZIP or RAR archive file containing the JPGs and send the archive file (e.g. by email) to the computer. When you extract from the archive file onto the computer the filename of each JPG will be the original, and the "date/time last modified" should be the original but If you find that the ordinary Extract does not preserve the file system "date/time modified" try extracting using another program such as RAR or 7zip. 

To print to PDF you need a PDF printer which can produce a left hand margin so use PDF X-Change Printer Lite rather than Windows' built-in PDF printer.  

When using Acute Photo EXIF Viewer, tap Settings and tick Show Image Preview and untick Show embedded preview if available. Tap File - Open and select the JPG - or click and drag it. Drag the blue preview bar to the right to show a reasonably large image. Tap File - Print and in the Print panel select a PDF printer of PDF X-Change Lite and choose the following printer options: Page size B4, Margin 10mm, Orientation Landscape, Layout type Standard, Sheet Size A3, Scale to Fit, and tap Print.

Note 

If the photo is in portrait AND there is GPS EXIF data AND the blue slider is fully to the right to produce a maximum-sized portrait image, that will cause the GPS data group to be pushed below the bottom of the page produced and, instead of appearing on a second page, it will be cropped and a blank second page will be generated. In this case do not have the blue slider fully to the right - move it so that it is still right of centre but not fully to the right. This reduces the size of the image and allows all the GPS data to fit in. The DPI values in the EXIF XResolution and YResolution fields are essentially meaningless for digital photos - the fields having been designed for scanners - and so it does not matter that the image size is less than the calculated "Print size" dimensions shown under "Image Summary" as long as all relevant details in the image can be clearly seen. If, in order to include the GPS data, you have to reduce the size of the image so that it is pixelated, or otherwise not sufficiently clear, you may need to use the original image file, together with the image-and-metadata PDF print. The original image file can then be consulted for the finer detail whilst the image within the image-and-metadata print is your proof that the metadata is from the same JPG.           

 How to create PDF prints in bulk efficiently for a number of JPGs

Starting off with JPGs in a folder - the "source folder" -  you can do the following to create PDF "prints" from each JPG each named the same as the JPG:
