Modern professional cameras don't do time/date-stamps. As digital files, that can be completely manipulated via software editing.


That's what I was thinking. Regardless what's saved with the original image, it can always be changed later. The exif data would have the time and date, though. Can that be easily changed?

Every attribute of the file is editable, EXIF as well as all the OS (non EXIF) values. If it has a 'tag' (identifier for the data storage content), an editor with the ability to access that tag can change the stored value. Even more sophisticated techniques can modify the data absent the simplified tag method.

Well, there goes "The Proof."

I agree with everything your saying; however, some of my clients require the date and time stamp on photos. If its required, then I do it since they use it and feel its adequate proof of completing an assignment. It provides a basis for the paycheck! "The Client is always Right."

Folks, I think you are a bit off center on this one. Yes, adding date and time stamp to a photo can be altered, manipulated, etc. But that is not the issue here. In security/ police issues, a photograph or any piece of evidence has to be authenticated by the one who made it, discovered it, etc. For photos, our photographers simply had a reference card with date, time, place, took a shot of that card and all subsequent shots were included in that batch. If the particulars were questioned then the photographer had to testify as the when the pics were taken. An exam of exif is not done generally. In fact, when the pics are included in discovery, they are copied along with the thousands of other docs as PDFs. The data on the photos are for reference for the multiples of people who will look at discovery. I know because Inhave received 100,000 of pages in discovery.

If a photo file is a QUESTIONED document/ object then forensic analysis is done. Think in terms of revenge porn etc taken by a suspect or witness where cops are trying to figure out when the pics were taken.

Im this case, if the photographer can authenticate the photo then there would be no issue.

Working in security, I sometimes need to have a date/time imprint on my pictures with my Nikon D780.
I cannot find where on a menu to do this. Any suggestions.


In answer to your original question, look for Date Stamp in the setup menu. It won’t work on raw or raw+jpeg

I disagree; the client is not always right and when they are not right it the vendors duty to explain why. In my 40 years as an IT professional, over 30 of which included designing and developing software applications, there were numerous times when the client made requests that were either impractical or simply not fiscally or legally possible. As the technical expert on these projects it was up to me to explain why we can't give them what they want and offer alternative suggestions, if possible.
No, the client is not always right and at times letting them believe so is doing them a disservice. The client is always right is similar to there are no dumb questions.

You can manipulate that too. EXIF is just text in the 'header' region of the file over the image data payload. I edit EXIF most every day when working with scanned film JPEGs to create images that have the rich EXIF as if from a digital camera, adding shooting dates, film ISO, camera and lens data, etc.
