How to Use ExifLens
- 1
Upload a photo
Drag a photo into the upload area at the top of the page, or click to choose one.JPG, PNG, and most camera RAW formats are supported, with up to 100MB per file.Your photo is never sent to a server — everything is processed inside your browser.
- 2
Read the EXIF data
As soon as the photo loads, the camera, lens, shutter speed, aperture, ISO, focal length, and the date and time taken appear in the “Extracted EXIF” panel.Photos that went through a messaging app or social network may have had their metadata removed, so some fields might not appear.
- 3
See where it was taken on a map
If the photo contains GPS data, click “View on map” next to the location row to see exactly where it was shot.Photos without location data leave this row empty.
- 4
Calculate your ND filter exposure
The ND filter calculator shows the shutter speed detected from your photo as the base value.Pick a filter strength or type in a custom number of stops to get the long-exposure shutter speed you need in the field, then use the built-in timer while you shoot.Matching gear recommendations for the selected ND filter are shown too.
- 5
Build a camera-info frame
Use “Create a frame” in the top menu, or the button that appears after uploading, to open the EXIF Frame Generator.Add a clean camera-info frame to your photo and download it at the original resolution — handy for social media and portfolios.
- 6
Protect your privacy before sharing
EXIF data can include where and when a photo was taken and what device shot it, so sharing the original file can expose personal information.Remove the metadata with the EXIF / Metadata Remover before you post.

Frequently Asked Questions
Real questions from photographers, pulled from across our tools and guides.
Why do the overcast variants use different apertures?+
Each stop of the aperture roughly corresponds to a lighting condition letting in about half as much light as the one before it, so the rule widens the aperture by one stop per condition to keep the same shutter speed reasonable.
Why is the 'equivalent aperture' different when compared to another sensor?+
Depth of field and background blur are governed by the lens's actual physical aperture diameter, not the f-number alone. When the field of view is matched across different sensor sizes, the f-number that produces the same apparent depth of field scales with the ratio of the two sensors' crop factors.
Do I have to grant location permission to use this?+
No — you can enter latitude and longitude manually and use the calculator without granting location permission at all.
Why does this only support Nikon and a few Canon models right now?+
Nikon documents this field (ShutterCount) as a plain, unencrypted number inside its MakerNote block, which we've independently verified against real camera files. Canon publishes the storage location for a handful of recent EOS R bodies — the R5, R6, R6 Mark II, R8, and R50 — so we support those too. Other manufacturers (Sony, Fujifilm, Olympus, Panasonic, Pentax) either don't store an equivalent value in the file at all, or store it in a way that varies by model and needs separate work per camera — we're expanding brand support gradually.
Why does the guide number change with ISO?+
A higher ISO makes the sensor more sensitive to the same amount of light, which is equivalent to boosting the flash's effective reach — but only by the square root of the ISO ratio, not proportionally. Doubling ISO increases the usable guide number (and distance) by about 41%, not 100%.
