How to Straighten Fisheye Distortion Without Guesswork

A fisheye lens locks you into curved horizons and bowed lines, but the 7Artisans 10mm f/2.5 for the Nikon Z mount ships with a way out. A free lens correction profile straightens those shots into a clean wide angle look, and applying it takes a handful of clicks.

Working from his review of the 7artisans 10mm f/2.5 fisheye lens, Adrian Alford walks through the exact steps in Lightroom Classic and Photoshop. 7Artisans posted sample images on its product page, including a stadium shot, an astro frame, and an interior looking up through a building. Alongside those, the company built a lens correction profile you can download directly, with before and after examples showing the fisheye curve removed. The download arrives as a zip file. Inside, you get a text file and a .lcp file. The .lcp is the one that does the work.

Alford imports the profile in Lightroom Classic through File, then "Import Develop Profiles and Presets," pointing to the unzipped folder and selecting the .lcp file. Importing it once set it up in Photoshop at the same time, so no second step was needed there. In Lightroom, the fix lives under lens correction: enable profile corrections, set the lens profile make to 7Artisans, and the fisheye bend disappears. A shot taken beneath a bridge shows the shift most clearly, where curved railings snap back to straight. He recommends running the lens correction before touching white balance, highlights, or shadows.

7Artisans notes that the profile works best on raw files straight out of the camera. In Photoshop, the process runs through the optics panel: click "Use Profile Corrections," choose 7Artisans under lens profile make, and the outward bowing along the frame flattens out. A frame shot straight up a palm tree makes the correction obvious, with the trunk pulling from a curve into a natural line. The whole sequence stays fast because the profile handles the geometry for you.

This is a good example of how a small extra file can widen what a single lens does. Buy one 10mm fisheye and you get two distinct looks: the dramatic curved perspective when you want spatial tension, and a corrected wide angle when you want clean architecture or landscapes. Camera and lens makers have leaned into this for years, shipping correction profiles that let optical designers keep lenses small and light while software cleans up distortion afterward. Adobe bakes many profiles into Lightroom and Camera Raw automatically, but third-party and budget lenses often live outside that database, which is why manufacturers like 7Artisans post their own. Knowing where to find a maker's profile page and how to import a .lcp manually is a skill that pays off across any off-brand glass you own. Keep the raw file, apply the profile first, edit light and color second, and you preserve the most correction data the sensor captured.
