Metadata for aircraft photos: using EXIF, IPTC and keywords the right way

A year of spotting, a few thousand photos, and suddenly the question: when did you last catch the A350 with the registration D-AIXA? Without metadata, all you can do is click through folders. With carefully maintained metadata for your aircraft photos, it is a search that takes a few seconds. This guide explains what EXIF, IPTC and XMP each store, which fields really matter for spotters, and how to tag registration, airline, aircraft type and location so your archive still works after ten years.

Metadata in one sentence

Metadata is data about your picture that is stored in the image file itself: the camera automatically writes when and with what you shot, and you add what is in the picture. The big advantage over file names or a separate spreadsheet: the information travels with the file – when copying to the backup drive, when switching photo management software and, if you want, when uploading.

Three terms come up constantly, and they are often mixed up:

	EXIF	IPTC	XMP
What it is	Camera standard for technical capture data	Standard for descriptive image information	Storage format for all kinds of metadata
Who maintains it	JEITA and CIPA (Japanese industry associations)	International Press Telecommunications Council	originally Adobe, now ISO standard 16684
Who fills it in	the camera, automatically	you, in your photo management software	the program, in the background
Typical contents	Time, camera, lens, focal length, aperture, ISO, GPS	Description, keywords, creator, copyright, location	contains IPTC fields, ratings, editing steps
Important for spotters	Date, time, focal length, GPS	Registration, type, airline, airport, spot	Sidecar files for RAW

In short: EXIF answers when and how, IPTC answers what and where, and XMP is the container in which modern software stores both.

EXIF: what the camera writes on its own

As soon as you press the shutter, the camera puts an EXIF block into the file. For spotters, these details are the most interesting:

• Capture date and time, often with fractions of a second. You use them later to match photos with flight data – for example to find out which flight an aircraft was operating. How that works is shown in the guide Matching sightings with ADS-B logs.
• Camera, lens and focal length. Handy for working out which focal length works at a given spot. If you have ever stood at the Munich Airport visitors’ hill with 400 millimeters, you know next time whether that was enough.
• Exposure: shutter speed, aperture, ISO, exposure compensation. Especially with propeller aircraft or night shots, you learn the most from these values.
• GPS position, if the camera has a receiver or is paired with a smartphone app. Smartphones usually write it automatically, as long as the camera app has access to location.

Since EXIF 2.31 there are also fields for the time zone offset. Many cameras fill them in by now, but you cannot rely on it. Older files only know the local camera time without a time zone – after a long-haul trip that is a classic source of errors.

What EXIF cannot do: describe what is in the picture. There is a simple description field, but no structured keywords and no clean location fields. That is what IPTC is for.

IPTC: the fields that matter for spotters

The IPTC Photo Metadata Standard comes from the news industry. Agencies needed a uniform way to carry captions, creators and rights directly in the file. The standard consists of a core section (IPTC Core) and an extension (IPTC Extension). Most photo management programs show you a selection of them as an input form.

For aircraft photos, these fields are the most worthwhile:

IPTC field	What you use it for	Example
Title	short name of the picture	D-AIXA Lufthansa A350-900
Headline	brief summary, one line	Lufthansa A350 lands in Munich
Description	full caption	Lufthansa Airbus A350-900 D-AIXA on final approach to Munich, runway 26R
Keywords	filterable single terms	D-AIXA, A350-900, A359, Lufthansa, DLH, MUC, EDDM
Creator	your name or pseudonym	your spotter name
Copyright notice	rights notice	© 2026 your name
Location Created	where you stood	Visitors’ hill, Munich, Bavaria, DE
Location Shown	what is visible in the picture	Munich Airport

The difference between headline and title matters: the standard explicitly stresses that the two are not the same. The title is more of a short name or identifier, the headline a brief summary of the content. Many spotters use the title for the combination of registration, airline and type – that works well because this line then shows up as the image name in many programs.

Location created and location shown

For spotters, one subtlety of the IPTC standard is especially useful: it separates the place where the photo was taken from the place that is shown in the picture. If you photograph an aircraft on approach from the Affenfelsen in Hamburg, the location created is the spot and the location shown is Hamburg Airport. For photos from the aircraft window or overflights at cruising altitude, the two are even far apart.

The older location fields in the core section – city, state/province, country, country code and sublocation – are considered legacy in the current standard, but nearly every piece of software still supports them. For the country code the standard calls for ISO 3166 abbreviations, so for example DE, AT or CH.

XMP and sidecar files: where the data ends up

XMP was introduced by Adobe in 2001 and is now standardized as ISO 16684. As a user, you mostly never see it, but there are a few things you should know:

• IPTC mostly lives in XMP today. The IPTC standard recommends writing the fields both in XMP and in the older IIM format so that old programs can read them too. Good photo management software does this automatically.
• RAW files often have sidecars. Many programs do not modify the RAW file itself but put an .xmp file with the same name next to it. It holds your keywords, ratings and edits. If you separate RAW and sidecar when copying, your metadata is gone.
• JPEG and DNG take XMP directly into the file. When you export from your editing software, your IPTC details therefore usually end up in the finished image automatically.

Whether you shoot RAW or JPEG therefore also changes how you secure your metadata. If you use RAW, include sidecars in your backup strategy or set your photo management software to also write changes into the files.

The spotter scheme: registration, type, airline, location

The technology is the easy part. What makes the difference is a fixed scheme that you stick with for years. A proven principle: the registration is the primary key. An aircraft can change airline, livery and home airport, while the registration often stays the same for a long time – and when it changes, that is interesting information in itself. You will find more in the article on re-registrations.

Around the registration you add the other attributes, ideally as plain text and as a code:

• Aircraft type: plain text such as “Airbus A350-900” plus ICAO type designator A359. The codes are short and unambiguous, more in ICAO type designators explained. For an Airbus A320neo that would be A20N.
• Airline: name plus ICAO code, so for Lufthansa that is DLH, optionally the IATA code LH. How the two systems differ is explained in the guide IATA and ICAO codes.
• Airport: name plus code, such as MUC and EDDM for Munich Airport or FRA and EDDF for Frankfurt Airport.
• Spot: your location, spelled the same way every time if possible.
• Special features: special livery, first flight, farewell flight, military, business jet – anything you want to filter by later.

A formula for the caption

For the description, a fixed sentence template that you always fill in the same way is worthwhile:

Airline – type – registration – situation – location – date

For example: Lufthansa Airbus A350-900 D-AIXA on final approach to runway 26R, Munich Airport, October 12, 2026. This structure is readable for people, unambiguous for search functions, and you can reuse it directly for uploads to photo platforms. How platforms such as JetPhotos expect the details is covered in the JetPhotos upload guide.

The more practical part – how to enter a registration quickly and without errors when captioning – is covered in more depth in the article Captioning photos properly.

Keywords as a hierarchy

Simple keyword lists quickly become confusing: “A350”, “A350-900”, “Airbus A350” and “a350” eventually sit side by side. Almost every serious photo management program therefore supports hierarchical keywords. You build a catalog in which every term has a fixed place:

Level	Example hierarchy
Type	Aircraft type › Airbus › A350 › A350-900
Airline	Airline › Germany › Lufthansa
Location	Airport › Germany › MUC Munich
Spot	Spot › MUC › Visitors’ hill
Registration	Registration › D- › D-AIXA
Theme	Subject › Special livery, Subject › Landing, Subject › Night

When you assign the lowest keyword, the program can write the parent terms automatically. One click on “A350-900” then also adds “A350” and “Airbus”. Lightroom, for example, additionally stores the hierarchy in a dedicated XMP field so that it is preserved when exchanging files. How to set this up in practice is described in the Lightroom workflow for aircraft photos; a comparison of the major programs is provided by Capture One, Lightroom and DxO compared.

A clean archive in five steps

The folder structure complements this system but does not replace it: folders by date or session, contents through metadata. More on this in the article Archiving aircraft photos.

GPS data: a blessing for the archive, a risk when sharing

GPS coordinates in the file are worth their weight in gold for your own archive: years later you can still see exactly where you stood, and you can visualize sightings on a map. If your camera has no receiver, you can add the position afterward from a GPS track. Programs such as ExifTool match the capture time against the timestamps in the track and interpolate the position – which again shows how important a correct camera clock is. The guide Geotagging aircraft photos explains the details.

When sharing, things look different. A photo with GPS data can reveal where you live if you photograph overflights from your balcony. Some platforms remove metadata on upload, others do not – you should never rely on it.

Creator and copyright, on the other hand, you should almost always leave in the file. They are no substitute for legal protection, but they make it traceable who a picture comes from. What legally stands behind your pictures is explained in the article Copyright for aircraft photos; how to set up exports for different channels is shown in Export settings for Instagram, forums and websites.

Common mistakes

• Typos in the registration. “DAIXA”, “D-AIXA” and “D-Aixa” are three different things to a search. Always write registrations in the official format with a hyphen and in capital letters. Background is provided by Understanding aircraft registrations.
• Type too coarse. “A320” is not enough if you want to distinguish between ceo and neo later. Assign the exact variant; the hierarchy adds the family.
• Airline instead of operator. With wet leases or subsidiaries, an aircraft often flies on behalf of another airline. Tag the actual operator and add the brand as a second keyword.
• Forgotten sidecars. If you move RAW files without their .xmp files, you lose all keywords.
• Different programs, different fields. Not every piece of software shows every IPTC field. Test once whether your details still arrive in full in another program after an export.

Once the foundation is laid, your archive becomes a data source: how many A350s have you got? Which airline are you still missing? The guide Analyzing your own spotting statistics shows how to answer questions like these. And if you also keep a logbook, Documenting sightings provides the right framework.

Conclusion

Metadata is the memory of your spotting archive. EXIF supplies time and technical data without any effort on your part, IPTC captures what only you know: registration, type, airline, airport and spot. XMP makes sure all of it is stored in the file or in a sidecar file next to it. What matters is less the program than consistency: a fixed scheme, codes alongside plain text, hierarchical keywords and a correct camera clock.
