Reading EXIF Data From Photos You Admire (And How to Use It)

For years I would scroll through photographers I admired on Flickr and 500px and wonder how they got the shot. I would study the composition, guess at the focal length, argue with myself about whether they used flash. Most of the time I was wrong. Then someone showed me the EXIF panel.

It was like turning the lights on. The photo I had assumed was a 35mm portrait shot wide open in window light was actually 85mm at f/4 shot two hours after sunrise. Everything I had been guessing was off, and the reason my own attempts looked nothing like it suddenly made sense.

EXIF data is the metadata your camera embeds in every file it writes. It tells you what the photographer used and when. It does not tell you everything, and the things it leaves out are just as important as the things it includes. But if you learn to read it, you stop guessing.

What EXIF Actually Contains

When your camera writes a file, it bundles a small block of structured data at the start. The standard fields most photographers care about:

• Camera body (make and model)
• Lens (make, model, sometimes serial number)
• Focal length (the actual mm, not the equivalent)
• Aperture (f/2.8, f/8, etc.)
• Shutter speed (1/250s, 2s, etc.)
• ISO
• Exposure compensation
• Metering mode
• Flash fired (yes/no, and sometimes intensity)
• White balance (auto, daylight, tungsten, custom Kelvin)
• Date and time (down to the second)
• GPS coordinates (if the camera or phone tagged them)

That last pair, time and GPS, is the secret weapon. More on that in a minute.

Tools for Reading EXIF

You have more options than you probably realize. Pick the one that fits where you spend your time.

In a desktop editor

If you already use Lightroom, the Metadata panel in the Library module shows everything. I keep mine set to “EXIF and IPTC” so I can see camera, lens, settings, GPS, and copyright in one view. Photoshop’s File > File Info > Camera Data tab gives you the same fields if you are not in Lightroom.

Capture One and DxO PhotoLab both expose EXIF in their info panels. Same data, slightly different layouts.

Standalone viewers

For inspecting other people’s photos, I use PhotoMe on Windows or Preview > Inspector (cmd+i) on macOS. PhotoMe shows you maker notes too, which is where Nikon and Canon hide things like focus distance and AF point selection. Preview is faster for a quick check.

ExifTool is the command-line option for anything serious. It reads more fields than any GUI tool, and you can pipe its output into scripts. I use it when I want to batch-analyze a folder of reference shots and look for patterns.

Browser extensions

For looking at photos online, EXIF Viewer Pro for Chrome or Exif Viewer for Firefox add a right-click option that pops up the metadata in a panel. Works on most photo-sharing sites, with one big caveat I will get to.

On your phone

iOS Photos shows EXIF natively now (tap the info button below the photo). Android varies, but Photo Exif Editor is reliable. For checking shots someone airdropped or texted you, this is enough.

What You Can Actually Learn From EXIF

Reading the raw numbers is one thing. Knowing what they mean for the photo in front of you is another. Here is what I look at first when I find a photo I want to understand.

Time of day plus location equals light conditions

This is the move that changed how I learn from other photographers. If I see a portrait I love and the EXIF says it was shot at 7:42 AM with GPS coordinates in Lisbon in October, I can pull up a sun calculator and see that the sun was about 12 degrees above the horizon, coming from the east-southeast. Now I know the light was warm, low, and directional. That tells me more than any tutorial about the gear.

You do not even need the GPS to be precise. A timestamp plus a rough city is enough to figure out whether the photo was shot during golden hour, blue hour, midday, or in deep shade. (If you want to dig deeper into reading those windows, my piece on golden hour vs blue hour breaks down the visual cues for each.)

Focal length tells you about distance

A 35mm portrait is shot from a few feet away. An 85mm portrait gives the photographer maybe eight to ten feet of distance. A 200mm portrait means the photographer is across the room. The intimacy of the shot changes with distance, even when the framing of the face looks the same.

When I see a photo where the background feels far away and compressed, I check the focal length first. If it says 135mm or longer, I know the photographer probably stepped back, not zoomed in from close range.

Aperture plus focal length tells you about depth of field

f/2.8 at 85mm from six feet gives you maybe four inches of sharpness. f/2.8 at 24mm from six feet gives you closer to a foot and a half. Same aperture, very different look. If you are trying to replicate a shallow-background portrait and your 24mm shots keep coming out with too much in focus, EXIF will explain why. (If depth of field still feels mysterious, my piece on understanding depth of field covers the math without the math.)

Shutter speed tells you about movement and stability

1/30s handheld at 200mm is a photographer who knows their stabilization or got lucky. 1/2000s at f/4 in daylight is freezing fast action. 2s is a tripod and patience. Shutter alone tells you whether the photographer was working fast or slow, with or without support.

ISO tells you how much light they had

Low ISO (100-400) usually means daylight, controlled studio, or tripod. High ISO (3200+) usually means available light at night, indoors, or somewhere they could not use flash. If a portrait at ISO 6400 looks clean and noise-free, you are probably looking at a full-frame body or heavy noise reduction in post.

What EXIF Cannot Tell You

This is where most beginners get tripped up. EXIF stops at the camera. Everything that happens after the shutter clicks is invisible.

You will not see:

• Post-processing. Lightroom edits, Photoshop layers, color grading, dodging and burning, frequency separation, sky replacements. None of that is in EXIF. The most edited photo in the world has the same EXIF as the unedited version.
• Lighting setup. Whether they used one strobe, three softboxes, a reflector, or pure window light. Flash-fired sometimes appears, but it does not tell you what kind of flash, how it was modified, or where it was placed.
• Crop ratio. EXIF shows the original capture dimensions, not what the photographer cropped to. A 35mm shot cropped to look like an 85mm framing reads as 35mm in EXIF.
• Whether they used filters. ND filters, polarizers, diffusion filters, mist filters. All invisible.
• What they pointed the camera at and chose to keep. The most important decision, totally absent.

I have spent hours trying to copy a photographer’s settings exactly only to realize the magic was in the editing, not the capture. EXIF will protect you from making bad gear assumptions, but it will not hand you the photo.

The Stripped Metadata Problem

Here is the thing nobody tells you. Most social media platforms strip EXIF on upload. Instagram, Facebook, Twitter/X, TikTok, and most messaging apps remove the metadata before serving the image. You can right-click and inspect all you want — the EXIF is gone.

A few exceptions where data usually survives:

• Flickr preserves EXIF by default and even displays it in a sidebar.
• 500px preserves it and shows it on the image page.
• Glass preserves it.
• Personal portfolio sites usually preserve it (the photographer chose what to upload).
• Reddit strips most fields but sometimes leaves camera and lens.

If you want to study EXIF, follow photographers on platforms that keep it. I curate a small list of accounts on Flickr and Glass specifically because I can learn from their settings, not just their compositions.

Watch Out for Edited or Faked EXIF

EXIF is editable. ExifTool can rewrite any field, and so can a half-dozen GUI tools. I have caught photographers tagging shots with wrong lens models (sometimes accidentally, when their camera misidentified an adapted lens) and a few who deliberately wrote in fake settings to make a shot look more impressive.

Sanity-check what you see. If a shot has razor-thin depth of field and the EXIF claims f/16, something is off. If a shot is tack-sharp at 1/15s handheld with a 400mm lens and no stabilization, be skeptical. EXIF is a clue, not a confession.

How I Use EXIF in Practice

When I find a photo I want to understand, I run the same checklist:

1. Check the time and location. Reverse-engineer the light. Was it golden hour? Overcast noon? Studio?
2. Check the focal length and aperture together. What is the depth of field telling me about distance?
3. Check the shutter and ISO. Was the photographer in bright light, available light, or supported on a tripod?
4. Check whether flash fired. If yes, look at the shadows in the photo to guess at modifier and direction.
5. Ignore the gear. The body and lens matter way less than the four points above. A Z9 and a Z6 III will produce the same image with the same settings in the same light.

That last point is the one I wish someone had told me five years ago. I spent too long believing the gear in the EXIF was responsible for the look. It was almost always the time of day, the position of the photographer, and the post-processing — none of which the camera body can take credit for.

EXIF will not make you a better photographer on its own. But it will stop you guessing about light, distance, and depth, which means the time you spend studying photos you love actually teaches you something. Open the metadata panel the next time you screenshot a reference shot. The numbers will tell you more than the photo did.
