Every digital photo is the result of a few decisions: how long the shutter stayed open, how wide the lens opened, how much the sensor signal was amplified, and how much of the scene the lens took in. Cameras and phones record those decisions in the photo's EXIF metadata. Reading them is one of the fastest ways to understand why a picture looks the way it does, and to repeat a result you liked.
This camera settings viewer pulls those values out of any photo you drop in and shows them as plain photography terms: shutter speed in fractions of a second, aperture as an f-number, ISO, focal length and 35 mm equivalent, plus the camera, lens, flash, metering and white balance. It runs entirely in your browser and works with phone and camera photos alike.

Shutter, aperture, ISO and focal length at a glance, with the camera, lens and date.
Example values. Phone photos usually record all of these; images exported from editors or downloaded from social networks often have them removed.
Drop the original JPEG, HEIC, PNG, AVIF or TIFF file into the workspace above.
The Camera & Exposure panel shows shutter speed, aperture, ISO and focal length at the top.
Below them you will find the camera, lens, 35 mm equivalent, exposure compensation, program, metering, flash and white balance.
Repeat with your other photos, or export each one to CSV with the metadata extractor to compare in a spreadsheet.
| Setting | What it controls | Low value | High value |
|---|---|---|---|
| Shutter speed | How long the sensor is exposed; motion blur | 1/1000 s freezes action | 1/15 s blurs motion and shake |
| Aperture (f-number) | Size of the lens opening; depth of field | f/1.8 blurs the background | f/11 keeps more in focus |
| ISO | Sensor amplification; noise | ISO 100 is clean in good light | ISO 3200+ is brighter but noisier |
| Focal length | Field of view and perspective | 16–24 mm (35 mm eq.) is wide | 85–200 mm is telephoto |
| Exposure compensation | Brighter or darker than metered | −1 EV darker | +1 EV brighter |
These three settings, often called the exposure triangle, together decide how bright a photo is, and each has a side effect. Shutter speed controls motion: 1/1000 s freezes a running dog, while 1/15 s blurs a waterfall and, handheld, risks camera shake. Aperture, written as an f-number, controls depth of field: f/1.8 lets in lots of light and blurs the background, f/11 keeps a landscape sharp from front to back. ISO amplifies the sensor signal: low values are clean, high values let you shoot in dim light at the cost of grain and lost detail.
When you look at a photo you are unhappy with, the settings usually explain it. A blurry handheld shot often shows a slow shutter speed; a noisy night photo shows a very high ISO; a portrait with everything in focus shows a small aperture.
Focal length decides how much of the scene fits in the frame. On its own the number is hard to compare between devices because sensors differ in size: a phone's main camera might have a real focal length of around 6 mm, while a full-frame camera uses 24–70 mm for similar views. That is why many devices also record a 35 mm equivalent, which translates the view into full-frame terms.
As a guide, around 24–28 mm equivalent is the typical wide phone camera, around 50 mm is close to natural human perspective, and 85 mm and above is a portrait or telephoto view that flattens features and isolates the subject.
Beyond the main settings, a few extra tags explain how the camera behaved:
Phone photos are heavily processed. The recorded settings describe a single exposure, but the final image may combine several frames for HDR, night mode or noise reduction, so a "1/10 s at ISO 1000" night photo can look cleaner than those numbers would suggest. Most phone lenses also have a fixed aperture, so the f-number rarely changes between shots.
Dedicated cameras record settings more literally, and lenses with variable apertures make the f-number far more informative. In both cases the metadata is a reliable record of how the capture was configured, which makes it ideal for learning.
A simple habit improves your photography quickly: pick five photos you love and five you do not, and look at their settings side by side. Patterns appear fast, such as the shutter speed below which your handheld shots blur, or the ISO above which your camera gets too noisy for your taste. Export each photo's settings with the metadata extractor to build that comparison in a spreadsheet.
See exactly how your best shots were taken and repeat what worked.
When you have the original file, the settings show how a photographer handled tricky light.
Slow shutter speeds and high ISO values explain most soft or grainy images.
Sample photos from a camera or lens for sale can show the model recorded in the metadata.
Drop the original photo into the viewer above. If the EXIF data is intact, the Camera & Exposure panel shows the shutter speed, aperture, ISO, focal length, lens and camera model.
The camera make and model are stored in EXIF and shown at the top of the Camera & Exposure details. Phones usually record their model name, for example a specific iPhone or Pixel model.
Small sensors, like those in phones, need short real focal lengths. The 35 mm equivalent tells you the field of view a full-frame camera would need for the same framing, so a phone lens of about 6 mm might be listed as 24–26 mm equivalent.
Editing apps, screenshot tools, social networks and messaging apps often remove EXIF. Ask for the original file if you need the settings.
Most phone lenses have a fixed aperture, so exposure is controlled by shutter speed and ISO instead. A few phones have variable apertures, and some simulate background blur in software.
No. The settings are read from the file in your browser, and nothing is sent to a server.
This viewer reads JPEG, PNG, HEIC, AVIF and TIFF. Convert RAW files first with the RAW to JPG converter, or check whether your camera saved a JPEG alongside the RAW file.
The exposure program shows who chose the settings: manual, aperture priority, shutter priority or an automatic mode. Metering mode shows how the camera measured light, such as across the whole frame (evaluative/pattern), mostly in the centre, or at a single spot.
