Features
Read full description

No more over-exposed and over-saturated videos. This app allows you to record 4K and HD videos with a flat, log color profile, which can be used in color correction software (not included in the app). It allows you to get more control over color tones and better exposure. It records in a wider dynamic range with flattened colors, so that you have maximum control in post-production. Do the colors look grey and washed out? That’s exactly the intention. The videos are captured with a log profile, meaning low contrast, low saturation and extended exposure range.  You get up to 2 stops of extra dynamic range, preserving highlights and shadows ! Recorded videos must be corrected with editing tools, such as DaVinci Resolve, Adobe Premiere, AVID Media Composer and Final Cut Pro. In grading, you should boost saturation, add contrast and lift the gamma curve. You can also use LUTs (for Sony, Panasonic, RED, Canon or Blackmagic), to see which preset color correction looks best on your shots. Record in 24, 25 or 30 frames per second. Select 4K or HD resolution. Choose from 5 flat color profiles: OFF, CINE, M-LOG1, M-LOG2, M-LOG3 Focus, ISO and exposure are automatically adjusted.

Photograph buildings without the lean. Meydn corrects perspective in real time as you shoot, so keystone distortion is gone before you press the shutter. No editing afterward, no upload, no account. For architects checking their own work. For real estate agents whose listings need straight verticals. For photographers tired of pulling lines in post. For anyone who has watched a tall building lean on their phone screen and wondered why it has to. Meydn reads the building's geometry through your iPhone's lens, applies the correction in real time, and writes the result to your Photo Library. The original photo is saved alongside the corrected one, so nothing is lost. Features: • Real-time perspective correction (tilt-shift, keystone) • On-device computation, no internet required • Manual exposure, HEIC capture • Original + corrected saved side by side in Photos • No account, no analytics, no cloud, no third-party SDKs In 1867, while measuring Wetzlar Cathedral from a scaffold, the Prussian architect Albrecht Meydenbauer nearly fell. Buildings, he decided, should not have to be climbed to be measured. He invented photogrammetry. His method was simple: keep the sensor plane parallel to the building, and the geometry stays honest. From his glass plates to tilt-shift lenses to Meydn on the iPhone in your pocket, every architectural photograph whose verticals stay vertical descends from that idea.
