Ratings & Reviews
Fixes to RAW support:
Trevni now supports RAW files from cameras, DNG, and ProRAW from iPhone. Your negative is processed at full resolution, preserving much more detail for conversion and editing.
Full-resolution export:
Save your finished positive as JPEG, HEIC or TIFF. TIFF keeps every pixel for further editing; JPEG and HEIC are better for sharing.
Your photo’s details come with it:
Camera, lens, exposure settings, date and location carry across to the saved image, so an inverted frame stays as easy to find in your library as the original.
Smoother to use:
Sampling the film base and moving the adjustment sliders are noticeably more responsive, especially on large files.
