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.

How Wide Is That Lens, Really? Calculating Field of View in Degrees
"35mm" or "200mm" only tells you so much on its own. Our Camera Field of View calculator converts focal length and sensor size into an actual angle in degrees — here's how to use it and why it matters.

Studio Lighting Basics: Shaping Depth with Three-Point Lighting and Lighting Ratios
One light left half the face buried in shadow, and adding more lights just flattened everything out? Here's how key, fill, and back lights split the work, how the inverse-square law predicts exposure shifts, and how to calculate a lighting ratio that actually adds dimension.

Finding Your Camera's Diffraction-Limited Aperture (and Why It's Not the Whole Story)
Our Advanced DoF & Diffraction calculator shows the aperture where diffraction starts to soften detail for your sensor size, alongside the resulting depth of field. Here's how to read both numbers together.

Frequently Asked Questions
Real questions from photographers, pulled from across our tools and guides.
I don’t know my camera’s exact megapixel count — what do I do?+
Pick the resolution preset closest to your camera’s actual megapixel count; the listed example models can help you match it.
What happens to location data when I compress?+
By default EXIF and GPS are removed. Only when saving a JPG as a JPG can you keep everything or remove only the location. If hiding location is all you need, the EXIF Remover tool also works.
Do I really need 300 DPI?+
Not always. 300 DPI is a common benchmark for prints viewed up close (albums, framed photos), but large posters or banners viewed from a distance can look plenty sharp at around 150 DPI. The farther the viewing distance, the lower the DPI you need.
Should I calculate based on RAW or JPEG?+
Use RAW if you plan to do significant editing afterward, or JPEG if you need ready-to-use results right away. If your camera saves both formats at once, add the two file sizes together and enter that total with the 'Custom' option.
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%.
